Question - 480x360 -> 720x480 HELP PLZ No.39742
bhh  2003-11-05 05:55:48 ( ID:qdrflxpyuvc )   [ Delete / Reply with quotation ]

This is driving me nuts. I've got some files at 480x360 that I'm trying to encode to go to DVD. Using the wizard, NTSC and everything and it doesn't matter what the hell I use for my video arrange method, the files that are being ouput are 720x540 and obviously aren't DVD compliant. What the hell do I do to get a 720x480 with this source footage???


B_Racer  2003-11-05 08:55:34 ( ID:0jd4rmr3tyn )   [ Delete / Reply with quotation ]

Setting -> Video -> Size -> 720x480
Setting -> Advanced -> Video Arrange Methode -> Center (Custom Size) -> 704x480
Setting -> Advanced -> source aspect ratio -> 1:1 (VGA)

But i suggest you to use AVISynth with the following Script and in TMPGEnc with the Arrange Methode Center.

AviSource("D:video.avi")
BicubicResize(704,480,0,0.6,0,0,480,360)
AddBorders(8,0,8,0)
ConvertToRGB24()

If you have Files that are 480+360 and want to make a DVD out of them I wouldn"t encode them to 720+480 because the Resize from 480+360 to 720+480 will totally Destroy any Definition and Clarity in the Image and you will end up with a File that looks Much worse as a DVD than it did as a 480+360 file..Up-sizeing destroys Image Quality especially when you are resizeing about 100%...What I would do is use the "Half D1" DVD standard which is a Mpeg2 file at 352+480 authored to DVD..So that the File stays in it"s original Aspect ratio set the Resolution to 352+480 but in the "Video Arrange method" set it to "Center(Custom Size)" and set the Size to 352+264, But if you don"t like how that looks because of the Black Boarders then choose "Fullscreen Keep aspect ratio" ....This will Give you a Much clearer and sharper Picture and you will only need to use Half the Bitrate and you can get twice as Much Video on the DVD......Good Luck


ashy  2003-11-07 20:41:25 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

Actually I'm gonna have to disagree with both of you.
@B_Racer
>Setting -> Advanced -> Video Arrange Method -> Center (Custom Size) -> 704x480

Why 704x480 and custom size when using 'Full screen keep aspect ratio' will maintain the exact ratio of the original whereas using custom and 704x480 will distort it slightly?
I hope it's not gonna be something to do with the overscan issue on this one either.

@minion
>Up-sizeing destroys Image Quality especially when you are resizeing about 100%...What I would do is use the "Half D1" DVD standard which is a Mpeg2 file at 352+480 authored to DVD..So that the File stays in it"s original Aspect ratio set the Resolution to 352+480

In my opinion it WOULD be better upsizing to 720x480. Using 352x480 is still upsizing the vertical resolution from 360 to 480, but then you would also be downsizing the horizontal from 480 to 352 which will only result in quality loss.
It would be better to just simply upsize it to DVD resolution and use the keep aspect ratio method.

I will agree though with B_Racer that it is better to use AVIsynth to resize than TMPG as this will maintain a better quality in the resized image.

Well, that's because 'Full screen keep aspect ratio' will distort the Video, custom size to 704x480 will not!

Remember, the Video is 4:3. 704x480 is also exactly 4:3. If he does a direct resizing to 720x480, the AR is no longer 4:3. (720x480 is equal to 704x480 plus 16 Pixels Overscan).

Jeez, i have to tell shh to correct Fit2Disc a little. ;)

I just Know from Personal experience when I first started to try to back up my SVCD Collection to DVD and resizeing to 720+480 allways looked awefull, I actually got better Quality resizeing down to 352+240 than I did Up-sizeing to 720+480...I ended up Just Authoring the SVCD"s to DVD the way they were which was the best option....I also Found that Up-Sizeing Interlaced material was especially bad , But with Progressive Footage it was OK, I guess it depends on the Source file...Cheers

@B_Racer
>Well, that's because 'Full screen keep aspect ratio' will distort the Video, custom size to 704x480 will not!

Sorry to disagree, but I don't think so!
Actually I don't disagree with you that 704x480 will produce the correct ratio. What I'm trying to convey is that using 'Full screen keep aspect ratio' will produce exactly the same results.

TMPG will automatically place the resized image with the exact same aspect ratio as the original within the 720x480 frame and create the 8 pixel border. If you test it you will see.

This is what the 'maintain aspect ratio' setting is for. TMPG will resize the image to exactly the same ratio as the original input ratio setting no matter what the output resolution is, so if it's 4:3 then TMPG will maintain this ratio and resize the image accordingly (namely 480x360 to 704x480) to fit inside the 720x480 frame.

@Minion

Minion I think your quality degradation when upsizing is due to using TMPG to do the upsizing.
If you use AVIsynth to do the upsizing you should see much better results.
Upsizing is best using a Bicubic method. I don't know what method TMPG uses, but I don't think it's Bicubic which is why the quality is always degraded.
I guess it may be Bilinear, or worse some other quick resizing method such as nearest neighbour (Ughh), which is just no good for upsizing and nearest neighbour is just no good for anything (in my opinion).


ashy  2003-11-08 14:04:59 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

@minion.
By the way minion it probably wasn't necessary for you to re-encode or resize your SVCD's at all.

You can use DVDpatcher to patch the resolution which will make any DVD authoring program accept it so you can author it to DVD.


Minion  2003-11-08 23:20:46 ( ID:/d4nypdxsbj )   [ Delete / Reply with quotation ]

Actually I do use AVISynth to Resize and when Resizeing that Much (Allmost 100%) and still Had really bad results, absolutly no definition or Sharpness and a Lot Of Blockyness in Dark areas even when useing 5000kbs-8000kbs with CCE 2-Pass and that is why I Just end up authoring the SVCD"s to DVD but didn"t use the Patching the Headers Method Because My DVD Player had Problems with those DVD"s, What I did was Used DVD-Lab which is Great for Authoring SVCD"s to DVD..I actually got Much better Quality resizeing Down to 352+240 from 480+480 than I did Upsizeing to 720+480 ,But I guess everyone has a Method that works for them...Cheers


B_Racer  2003-11-10 09:22:16 ( ID:0jd4rmr3tyn )   [ Delete / Reply with quotation ]

@Minion

On Videos with a Resolution like this one here in the Thread, i prefer to resize to 352x480, unsing Bicubic with a Factor of 0.5 - 0.6.
"Upsizing interlaced"? Huh? What's that? Interlaced Video HAS to have the vertikal Resolution of 480 or 576, all other Stuff isn't interlaced, it is distorted. So there's absolutly no need to do any Resizing-Job on interlaced Video except for coversions NTSC-PAL, PAL-NTSC.
If i convert NTSC interlaced Video to PAL, i do a interlaced Resizing using AVISynth (after SeparateFields), it works perfect.


@Ashy

I did'nt say, your Methode is wrong, but for Newbies, it might be a little Dangerous. If he don't know the exact Source-AR of the AVI and do use the wrong setting, Keep aspect ratio will not do a propper Job.
But like you said (and me too): it's better to use an other Tool to do the Resizing because TMPGEncs Resizer is a simple Bilinear working thing (i guees so, the Results do look like simple bilinear resized).
If you use AVISynth or VirtualDub to do the Resize-Job, it's a good Idea to use Center in TMPGEnc. That's the fastest and imho save Way.



Question - Burning MPEG onto CD-R No.39738
lloydgump  2003-11-05 02:39:41 ( ID:xwd.nn0r/uk )   [ Delete / Reply with quotation ]

I am trying to burn an mpeg movie onto a CD-R....have encoded the movie to mpeg, from AVI with TMPGEnc. Do I just burn it onto a disk, or do I need another program to do this?


uxbridge  2003-11-05 17:44:42 ( ID:vzqtdfw3ffa )   [ Delete / Reply with quotation ]

No, you need an authoring program.
Assuming you've created a VCD or an SVCD, you can use NERO or VCDEasy, the second is a better choice to my opinion


Sakuya  2003-11-06 01:15:21 ( ID:6y4cusar5hr )   [ Delete / Reply with quotation ]

Sorry to barge in, but why is VCDEasy better than Nero? Is VCDEasy free? I use Nero 5 and it adds more minutes to my VCD, plus, the video in the VCD stops a few seconds shorter than it was intended to. But then again, it might be my DVD player's problem.


Minion  2003-11-06 05:31:20 ( ID:/d4nypdxsbj )   [ Delete / Reply with quotation ]

I find VCDEasy a Better authoring Program because it supports Chapters and has better menu options but it"s Burning engine isn"t very reliable ,So I used to use VCDEasy to add chapters amd menu"s then make a Bin/Cue file that I burn with nero....



Question - Aspect Ratio and Video Arrange Method - Help Needed No.39736
Tomas  2003-11-05 00:55:41 ( ID:w9nioantxtg )   [ Delete / Reply with quotation ]

I'd appreciate if someone "WHO KNOWS" will explain the setting of the aspect ratio parameters.

When I start the TMPGEnc with the Wizard and pick the AVI file (Captured by Scenalizer from Sony TRV900) the Aspect Ratio in Expert Settings for Source portion of the screen shows 4:3 525 Line (NTSC, 704x480) - Is it correct or should I change it to 4:3 525 line (NTSC) or even 4:3 Display

Next when I go to Other Settings, Video Tab the spect ratio there is set to 4:3 Display
And finally I go to Advance tab and look at Vidoe Source Settings - It looks like this Aource aspect ration corresponds to whatever I selected at the very beginning at the Expert Settings for Source part of the Wizard. And again; What should it be?

Another confusing part on this tab is the Video Arrange Method. Does it matter how it is set if I'm producing the DVD for the NTSC TV Output and I'd like to keep original size and aspect ratio?

I come accross the following explanation for Source aspect ratio and Video arrange method. Are they correct?

>>>>
***Source aspect ratio
If source footage dimensions are the same as the output dimensions, then selecting 4:3 Display or 16:9 Display (depending on the format) for both the source and output aspect ratios will ensure that no resizing is done (which makes the encoding faster and preserves the source quality). Alternatively, you can select the n-Line mode that corresponds to the source file's format (ex., for a 4:3 PAL file captured at 720x576, select 4:3 625 line (PAL), and for a 16:9 NTSC file captured at 704x480, select 16:9 525 line (NTSC, 704x480), etc.). In older versions of TMPGEnc, the n-line modes compressed the image horizontally by a few pixels in PAL, but this problem appears to have been fixed in newer versions. Note that the 1:1 (VGA) option doesn't refer to square images, but to square pixels (the format used by most computer-generated images).

***Video arrange method
If your source footage has the correct size (i.e., the same as the output size, selected in the Video tab), any method you pick will produce the same result. If the source footage has a different size, then it will be resized using the rule you define here. If you do not want the video to be resized at all, select Center. If you want the video to be stretched to occupy the entire screen, select Full screen. If you want the video to be resized in such a way that it keeps its original aspect ratio even when that's different from the output aspect ratio, select the modes marked (keep aspect ratio). If you want to convert a video clip to fullscreen without letterboxing it (by clipping the edges instead), select No margin. If you want to adjust its size manually, select Center (custom size).

Generally, if your source footage does not match the DVD resolution, it's best to resize it using an interactive program (that will show you the result immediately), and then feed the resized footage into TMPGEnc. If you resize directly in TMPGEnc you will only see the result after the compression is finished, so if you select the wrong mode you will have wasted a lot of time.

Thanks for any clarification, Tomas

You are mostly right, but:

> If you resize directly in TMPGEnc you will only see the result after the compression is finished

You can use the Prview Mode to see if it is correct.

About the Keep Aspect Ratio settings: They are dangerous. Without any Resizing, there are only two Modes which will work correct all the Way: Center and Full Screen.
Because many Source-Vids didn't have a correct DAR and/or PAR, with Keep Aspect Ratio you will get a distortet Result

I am trying to convert a 500MB file that is 480x480 to 720x480 and when it is done it comes out to be 1.2GB. Is there any way to make this so that it stays approx thesame size?

Thanks!

Ryan



Minion  2003-11-05 02:20:30 ( ID:/d4nypdxsbj )   [ Delete / Reply with quotation ]

Let me Guess you are Trying to convert SVCD to DVD???? Bad Idea...Converting from SVCD to DVD or from 480+480 to 720+480 will totally Ruin any quality the Image Had and you would need to use about twice the Bitrate which means the File will probably be about twice the size of the SVCD Files...What I would sugest is to author the SVCD"s to DVD as a Non-Standard DVD...Most DVD Players should Play this Type of DVD without a problem and there will be No quality loss...There is a DVD authoring Program called "DVD-Lab" that will author SVCD"s to DVD, I used it for backing up over 400 SVCD"s to DVD and they all worked Flawlessly in all DVD players I have tried them in...You can download a Fully working 30 day demo of DVD lab at :"http://www.mediachance.com/dvdlab/"..

So to your Question...No you can"t keep the 720+480 file the same as the SVCD files ,Well you can if you use a Low enough Bitrate but at a Bitrate that Low and encodeing from SVCD Files the Quality will be Just Horrendous....good Luck



Question - Cannot search in Media Player No.39732
Jay  2003-11-04 20:33:38 ( ID:cjvtc6zw7k6 )   [ Delete / Reply with quotation ]

Hi,

I've been trying to encode my DVD movies to SVCDs..
NTSC, 4:3, CQ....

Anyway I tried to rip this movie with DVD2SVCD (using the TMPGEnc)
and the results were fine, except the BeSweet Audio encoder thats
included was crap.. (like Downmix Overflow where it makes this annoying
BEEP and TICK sounds... like a bad encoded mp3)

But I I realised that I can use DVD2AVI to get the WAV file extracted
from a VOB file, then encode the VOB file in TMPGEnc with the WAV file
extracted from DVD2AVI.

Anyway to get to the problem, Windows Media Players are not taking the
file so well. It gives errors if i try to search the movie, fast forward
or something. However there is no problem when I burned the encoded
mpg file on to a SVCD and played it on my DVD player...

Does anyone know what the problem is?

Thanks in advance


Minion  2003-11-04 22:55:34 ( ID:/d4nypdxsbj )   [ Delete / Reply with quotation ]

This Probably because WMP Sucks For Playing Mpeg2 files and uses a Pretty Crappy Decoder if it is Useing the Decoder that comes with Media Player 9...You should be playing your Mpeg2 files with a Software DVD Player like WinDVD or PowerDVD then you should be able to Navigate the File without Problems.....

Question - DVD Text Issues No.39725
JBreits  2003-11-04 02:56:06 ( ID:t/izlzje1yw )   [ Delete / Reply with quotation ]

I have a 1.5 hr movie which is a compilation of several home movies. At the beginning of each section, I have some text that fades in, displays for a few seconds, and then fades out. I'm trying to use TMPGEnc so I can better control the resulting file size and thus fit teh entire movie on one DVD.

First, I encoded everything with a contant bit rate of 4965. Everything seemed ok. It encoded well, it worked well with the authoring software, it burned fine. I was able to play the DVD perfectly on my PC. However, when I put it in to my standalone DVD player (memorex), the text fade sections did not work. To be exact, the screen just stayed blank and the text never appeared.

I then tried several smaller files with just the text fade in/out with several of the different options in TMPGEnc. It turns out that using the Constant Bit Rate, the text never showed up. Even at 8000 bit rate. I did a test using 2-pass VBR Min:0 Max:8000 Avg:4000 and the text fade worked perfectly.

So I re-encoded my entire movie using the following settings:
2-Pass VBR
Min: 1000
Avg: 4900
Max: 7500
P Spoilage: 0
B Spoilage: 20

GOP: IBBPBBPBBPBBPBBP
Closed GOP: Y
Detect Scene Change: Y

What I got was a movie, that would fade the text in correctly, but while the text was static, it would appear to be "jumpy" or have fuzzy edges, then the fade out would look fine as well.

This is my first DVD and I think I have everything figured out except the correct settings for encoding the MPG file. The text fade looks great if I use some simpleton software like Sonic MyDVD. But that won't let you change the bit rate (therefore, the size can't change) and the menus suck.

Can some one help me out?

Thanks,

What Audio format are you useing with your DVD??? If you are Useing wav audio then that could be why the DVD Files are so big as Wav Files are Huge and it is better to use a Different format even Mpeg 1 layer 2 audio is better than Wav just because it takes up so much disk space..At an average bitrate of 5000kbs with mpeg audio at 224kbs you should be able to easilly fit 2 hours on a DVD-R ...As for the Fade ins and Fade outs not working on your DVD Player but they do work on your PC then it seems like a DVD Player or Burning program problem and not a Tmpgenc encodeing Problem..Tmpgenc will only encode what is On the Video and will not change it in a way that you seem to be sugesting.....cheers


JBreits  2003-11-04 13:40:56 ( ID:3/z0k74zo2h )   [ Delete / Reply with quotation ]

I was using WAV but I don't see how that would affect whether or not my text displayed correctly. And I don't see how it can be a player problem if the player will play it correctly if encoded by another software. It's definitely got to be the way it is encoded in TMPGEnc. Would the Detect Scene Change have any affect on this? How about the minimum bit rate or GOP structure? Any suggestions?

Video Guy  2003-11-04 17:58:32 ( ID:4yfrh0hqv72 )   [ Delete / Reply with quotation ]

What program did you use to create the text? Many programs render the text as Progessive frames. Go back to the program and see if you can set the render option to interlaced. This may be why its fuzzy and jumpy.


Minion is correct.

Wav audio is huge compared to mpeg audio. Most of the time your ears can't tell the difference between the two. Your text may appear fuzzy because it may not be given enough bitrate by the encoder. By compressing the audio and can give much more bits to the video stream and thus clearer video.

Use the GOP defaults that are in the TMPGEnc DVD template.

It makes no sense that you would get a black screen using CBR and then have it show up in VBR.

What is the format of your source. Is it avi? If it is, is it uncompressed or DV or something else? If the text is in the source avi file then it should be shown.

I do 1.5 hour encodes all the time which I burn to dvd. I use CQ, Max at 6500, Min at 2000, Audio at 256. I find that CQ gives much better results then the two pass VBR, plus its takes less time to encode.

Video Guy.


JBreits  2003-11-04 19:34:25 ( ID:3/z0k74zo2h )   [ Delete / Reply with quotation ]

The text was created in Adobe After Effects. And the movie was output as a DV AVI file. I assume the render out of AE was interlaced but I will check tonight.

I was using the default GOP structure unless I am mistaken.

As I mentioned earlier, I did a test on a much smaller video (30 sec) that included the exact same text fade in/out. The best test was from the 2-pass VBR. During testing, the CQ setting showed the text, but it was fuzzy and jumpy. But I will try one with your settings.

The were some differences between the test video that looked great and the actual full video.

The test had:
min: 0
max: 8000
avg: 4000

The actual:
Min: 1000 (I thought this would improve quality)
Avg: 4900
Max: 7500

I agree that encoding my audio would allow me a higher bit rate for my movie. But what kind of a bit rate should static (not moving) text require? I wouldn't think much. Also, that wouldn't explain why when rendered with a cbr of 8000 (pretty high I assume) the text did not show up.

I'll try some of these things out tonight.
Any other tips?

Thanks for your help
Josh



Free talk - Possible Fix f/ illegal mpeg audio stream No.39723
g_raas  2003-11-04 01:55:22 ( ID:u7ojvc268zj )   [ Delete / Reply with quotation ]

For those of you who are experiencing the error "illegal audio mpeg stream" or some such;
If you are downloading the image files say from IRC or some such and are using ISObuster or WINiso or VCDgear to create SVCD-DVD's.
Please be aware that your problem may be caused by the fact that you are merge/cutting mpeg files (both vid/audio) using the EDIT utility in MPEG tools prior to reencoding the audio. If this is the case any significant overlap in your merge can cause the stream to become unstable/corrupt (audio will sometimes unsync as well. So if you are merging your files (disc1 to disc2) either: make the merge points seperate chapters in your dvd authoring tool of choice or: de-multiplex the audio & video stream re-encode just the audio to/224bit/48000Hz MPEG layer II - then multiplex the vid/audio again (view to ensure sync) after this has been performed you can than progress to merging the discs/files and not have to worry about the illegal mpeg stream issue.
Its worth trying as I no longer have this problem.

I found it better to Not use Tmpgenc for File mergeing at all..I would use Mpeg2VCR to Merge My SVCD Files then after mergeing I would demux the Mpeg audio and encode it to AC3 audio at 48000hz, then Use a Program called "DVD-Lab" to author the SVCD files to DVD..It is the best program for authoring SVCD to DVD and it has all the Features that any good authoring Program has like Motion Menu"s and AC3 and DTS support and Chapters ...I backed up over 400 SVCD"s to DVD useing it and all of them were flawless....Cheers



Question - Burning DVD No.39719
Thomas  2003-11-03 23:19:56 ( ID:bp4oyjfiysl )   [ Delete / Reply with quotation ]

I am burning movie to DVD. For just 48 minutes, it takes up 3.4G. According to specifications, a 4.7G DVD takes up to 155 minutes. Is there any settings I need to do?

What determines the Size of your Mpeg file is the Length of the File and the Bitrate used to encode the file...If you Lower the Bitrate you also lower the size of the File and lower the Quality..and you have to realize that Tmpgenc could be adding the Size of the Wav audio to the Overall Size of the mpeg file, so the Video Might just take up 2.5gb but the audio could be takeing up 1gb..Wav audio is Not really good to use in DVD"s Because it takes up a Lot of Space on the DVD Disk, and the Only other Audio format that Tmpgenc will encode to is "Mpeg-1 layer 2 audio" which does only take up about 10% of what wav audio takes up but the Quality isn"t as good..so if you set the audio to Mpeg 1 Layer 2 your Projected file size should greatly decrese..I usually encode the Wav audio to AC3 which is the best format for DVD because of it"s Small file size and High Quality...When Makeing a Standard Full D1 DVD you can get about 2 hours of Video on the DVD at a Bitrate of about 5000kbs and an AC3 or Mpeg audio Bitrate of 224kbs..That will Produce quite good Quality but you shouldn"t go much lower than that if you want to achieve any sort of Quality image..You could not fit 155 minutes of Standard Full-D1 Resolution Video on a DVD, If you want to put more than 2 hours on a DVD-R I would sugest useing a Different DVD Format Like "Half D1(352+480/576-Pal)", You can get about 3.5 hours of Good Quality video useing this DVD standard and the "SIF Standard (352+240/288-Pal)" you can get up to 6 Hours of Fair Quality Video on a DVD-R...well I hope this Info helps...Cheers

Thanks for the details info.
It looks like if I use TMpgEnc, I can only use Mpg-1 Layer 2 audio to burn a 2-hr DVD. How can I do it in AC-3?


Minion  2003-11-04 06:40:53 ( ID:/d4nypdxsbj )   [ Delete / Reply with quotation ]

Well to do it is AC3 you would need an AC3 encoder to encode the Wav audio files to AC3..and your DVD authoring Program will have to support AC3 audio files as Many lower end Ones do not like Most DVD Apps Made by Ulead...Most AC3 encoder are Very expensive but there is one freeware one that I know of and it is Called "BeSweet" I found it hard to use so i never bothered figureing it you...I have a Fairly High end Video editing Program called "Vegas Video 4" which comes with a High Quality AC3 encoder built in and that is what I use for AC3 encodeing ..And you have to make sure your DVD authoring Program supports AC3 audio as Some Lower end ones do not...well good Luck and you can probably get away with useing Mpeg 1 Layer 2 audio But make sure you use a High Bitrate which will give you better Quality, 384kbs will achieve Quite good Quality in Sterio....Cheers



Question - can not open, or unsupported No.39714
Tomas  2003-11-03 05:49:45 ( ID:jgk7gdvxbnk )   [ Delete / Reply with quotation ]

I'm converting the standard NTSC AVI file to MPG2 using 2-pass VBR, and every time at 50% (after Analyzing) I get the "can not open, or unsupported" error. I tried few times with the same results. I also changed the priority on VFAPI plugin - Direct Show Multimedia File reader to 2 - it did not help.

The strange thing is that just other day I have successfully converted another AVI file (created same way as this one - Using Ulead Video Editor 7.0).
This behavior is puzzling. Any suggestions?

Tomas

This Is Rather wierd..When it is analizeing can you see the Picture in the Tmpgenc window??? usually when I run across a File that I can"t just simply encode in Tmpgenc for some unknown reason I usually try to frame serve the file to Tmpgenc useing either AVISynth or Virtual Dub which usually works..Does it encode normally when useing the Regular Encodeing modes like CBR or CQ??? Because if your Source AVI file is of High Quality then you will not get any noticeable quality gain useing 2-Pass compared to the Constant Quality method, and only Marginal improvements when useing Low Quality or Noisy source files....Well either way Im sure if you tried Frameserveing the file tmpgenc will encode it normally unless there is something wrong with the file like it was a downloaded file as Many downloaded movies just aren"t reliable...good Luck

Thanks for your quick response.
I tried the CQ and it worked OK.

I'm still wandering why it does not worked for VBR setting. I use this setting 95% of the time and usually have no persistent problems.
I've seen people suggesting that the MS WMP 9.0 may create the TMPGEnc processing problems. Can this issue apply to my problem.

There were Problems with WMP 9 and Blocking access to some Mpeg-4 codecs but I believe those Problems have been resolved cuz I now use WMP 9 and I don"t have any problems..But I do occationally get a File that I can play Fine but Tmpgenc will Just not load no matter what settings I use but with these Files I usually Just frame serve them which solves the Problem 99% of the Time...Cheers


Tomas  2003-11-04 18:03:12 ( ID:w9nioantxtg )   [ Delete / Reply with quotation ]

I found the reason for the TMPGEnc to crash at 50% of 2-pass VBR. It only happens if I use the "Center" setting for Video Arrange Method. Go figure, I changed it to "Full Screen (keep aspect ratio)" and it completed OK.

Question - How do you encode to widescreen/ 16:9 No.39711
Nova  2003-11-03 02:48:17 ( ID:l2e/t7t/a0f )   [ Delete / Reply with quotation ]

The movies im trying to encode are in widescreen so i heard that its best to encode them that way. I have actually gotten it to do it this way once but i have no idea what i clicked on to do it. Im even clicking on the 16:9 aspect but it still doesnt work

Quick guide for PAL DVD only...
First of all, You must have a project file (You can do this using DVD2AVI - File/Open --> select *.vob which contains the main moovie, next go to Audio --> Output Method and check Demux All Tracks, next go to Video --> Field Operation and check None, next go to Color Space and check YUV 4:2:2. Next File/Save Project --> usually it takes about 10 to 15 minutes).
It gives You a project file *.d2v and demuxed audio file *.ac3.
Next You can start Tmpeg application...
Give path to Video source and output file name...
First - check box ES Video Only, and press Settings
At Video window:
- stream type: MPEG-2 Video
- size: 720x576
- Aspect ratio: 16:9 display
- Frame rate: 25fps
- Rate control mode: 2 pass VBR
Settings:
- Average bitrate (set required value)
- Maximum bitrate (circle about 8000kbps)
- Minimum value (leave as is - 300kbps)
- Profile and level: Main Profile and Main Level
- Video format: PAL
- Encode Mode: non interlaced
- YUV format: 4:2:0
- DC component precision: 8bit
- Motion search precision: Motion estimate search (fast)
The 2 last options You can change as You prefer - it depends by quality which You request...
At Advanced window:
- Video Source Type: Non-Interlace (Progressive)
- Field Order: Bottom Field First (field B)
- Source aspect ratio: 16:9 display
- Video arranged method: Full screan (keep aspect ratio)
other options I usually didn't use...
At GOP Structure:
I frame: 1
P frames: 4
B frames: 2
Output Interval of sequence header: 1
and check Detect scene change
You can use Force picture type settings and load file which can be produced by IFOEDIT... In this case You can uncheck Detect scene change...
At quantize matrix - leave as is...
After few hours you get the output file *.m2v...
Then go to IFOEDIT for example, press Author new DVD, give path to your *.m2v file, your *.ac3 file (which You have been demuxed earlier...), give path to output file, ant thats it!
I know taht is a very short description (guide) but it should works pretty well...

Thanks for the info. About that DVD2AVI.. i dont know if i downloaded the wrong version or something.. but it only lets me open MPEG-2 files. Im trying to open an Avi file though. Do i have to make it mpeg first then open it in DVD2AVI?
