Some of the xvid/divx video files that I have tried to convert to dvd format TMPGEnc overcalculates the lenth of the video by like 3x. ie. a 24 min video file is calculated by TMPGEnc to 80 min. And after the encoding this perticular video there was no sound at all just the film rolling. Are there any plug-ins or solutions that i can obtain to solve this problem?

Can you tell me if the ac-3 plug-in will convert all audio, INCLUDING, audio used for bgm?

No, you can only convert between these formats :
MP2 - Linear PCM - AC3 ...
as it it is for TMPGEnc DVD Author.

I noticed a question someone asked "Can you tell me if the ac-3 plug-in will convert all audio, INCLUDING, audio used for bgm?"

This is just a hunch, but I think the guy was asking this "why does dvd author render ac3 audio for tracks, but when it renders BGM audio it turns even ac3 original audio from a video file into PCM?"

frankly, I too have the same issue. I have a small mpg2 video file i made using a still image, mixed with a 30second audio clip. the audio is in AC3 format. i use this 30 second video file as my background menu for my dvd. and of course, i check off "use audio from background video as BGM"

in my environmental settings i have selected both options to re-encode any pcm or mp2 audio into ac3. YET dvd author always turns my ac3 audio from the BGM into PCM. can you imagine, even after having both options checked off to convert ANY pcm or mp2 audio into ac3 AND using ac3 format to BEGIN with - it turns my ac3 BGM into PCM!

what GIVES here?

Capture device: Hauppage PVR 250

I'm capturing videotape concerts to burn as dvd's. I have no sync problems what so ever using DVD Movie Factory 2 to author. I much prefer TMPGENC DVD Author for it's menu options & styles. However everytime I try to author with DVD Author I get a/v sync problems. I've tried demultiplexing & multiplexing with TMPGENC PLus & that file to author > still have sync problems.

Using the following to capture:
"Output Type": Program Stream
720x480
VBR 6400 - 8000
GOP 15
Stereo MPEG1 Layer2
48KHz
384kbs


Is there a way to fix this problem? I've seen many posts about sync problems with DVD Author?

Solutions????

hi!

i'm afraid i cannot help you well, but at least i can tell you what the problem is, and give you an educated guess, why it works with (some) other software.

so.
the problem is, that your audio and video capture-rates do not match.
that's nearly always the case when different boards are used to cap audio and video, means video by some tv-card/gfx-card with vivo"/... and audio by the soundcard.

so the theoretical capture-rates are lets say 29.97fps/44100Hz, but the real caputre-rates differ from that a little - maybe 30fps/44100Hz or 29.97fps/44066Hz or something like that.

since most capture-apps use the audio-track as reference-time, the video-rate will be adjusted to match the audio stream - giving you a video stream of 29.998fps or 29.968fps or similar.
but since neither of these are MPEG-standard, the capture-app will write the mpeg-headers with the theoretical framerate of 29.97fps, but the gop-timecodes will recieve the timestamps calculated from the audio-stream, which will be the real-framerate, that is off by some amount.

and when you finally feed the file into tmpgenc-dvd-author, it will remultiplex the audio and video streams, using the "standard NTSC" framerate told by the mpeg-header, and NOT the gop-timecodes, which is why you will get a a/v lag which will increase over time.

(BTW: this is also the reason why you get a/v sync when you remux the file using tmpgenc mpeg encoder - you don't even need to author - try the remuxxed file in media-player - it should give you the same sync problems)

the reason it might work with some other app is, that probably not all author-apps rewrite the GOP timecode when remuxing files.
but that way you would end up having a non-standard conform dvd-disc, that might introduce strange behaviour when played by some picky hardware-players.
also, because the video-framerate is not standard, video will be jerky, even if it might be very subtle (depends on the amount of the a/v-rate mismatch when capturing).

some imperfect "solutions" i can offer you:
* cut the mpeg file into small pieces like 5 minutes or so, and add them to the project as independant files (you can use the same title though!)
* demux the file to audio and video, convert audio to wav, and use some tool like "sox" to strech the audio-stream so that it fits the length of the video-stream. then reencode to mp2, 48khz, and use that file as audio-source for tmpgenc dvd author. - you can use virtualdub to tell you what stretch-factor you will need (open mpeg file, menu: "video"|"frame rate..." -> read the value in braces after "change so video and audio durations match" -> calculate "that_value/29.97" (or 25 for PAL) -> that is your stretching factor)
* capture using a combined a/v capture-board
* use a capture-app that can sync on video, and dynamically resample audio for that purpose

hope that helps!

Wow, lot's of info there! I'm finding out I'm not the only one running into sync problems. Thank's for the info.

I am trying to convert a .divX movie file to mpeg or VCD....however I get an error: "file name.divx cannot open, or unsupported" Am I wrong to assume that this program does not convert .divX files to other formats?

Thanks in advance,

Hello Everybody ..

I'm currently using TmpgEnc create dvd from mpeg "dowloaded" from sat.

My Target is a PAL DVD at Half D1 size (352*576).

I use an AviSynth script to do the following:

1 - Separate the fields of the source video
2 - Crop them and resize them singularly to 320x256
3 - adding a 16 pixel black border to 352x288
4 - Rebuild an interlaced frame 352*576 in size

I produce and Avi File with a lossless coded wich I then
(finally :)) compress with TmpgEnc.

I use CQ at 100% quality 8000 as maximum bitrate 0 minimum bitrate.
VBV size is 40.

During PlayBack the movie shows some sudden gaps in playback.

I read some other posts on this BBS and I think that is the main
cuplrit of this are VBV too small.

My questions are:

1 - Is there a way to calculate an appropriate value for VBV or I
Should just set it to 0 and let TmpgEnc do the job ?

2 - It is better to add the borders to the file or it it better to let
TmpgEnc to center the image and add the borders by himself ?

3 - The resulting Mpeg has a average bitrate of 3500, in other posts
I have read that the minimum bitrate should not be set to 0.
Has anyone some indications of how to calculate an appropriate value ?
Should I also padded it ?

Thanks in advance for any help.
I also welcome any comment on the process used.

320x256 is a bit small for a single field, better resize to 336x280 or 336x276.

VBV of 40 is way to small, set it to 224 for DVD.

CQ of 100% gives you a kind of CBR-Encoding.

Never set Min lower than around 1300 kbps, some Players do not like lower Min-Bitrates.

Never use Padding!

Oh, and there's no need to produce an AVI first, open the AVISynth-Script directly in TMPGEnc.

Thanks for the Info.

I'll raise the VBV size to 224 and I'll run some tests.
BTW. is it possible to change it without re-encodig the video ?


> 320x256 is a bit small for a single field, better resize to 336x280

I choose that dimension because I want to make the borders size a multiple
of 16 which is the MPEG block size.
The resulting size is within the PAL Safe area anyways.

> CQ of 100% gives you a kind of CBR-Encoding.

Do you mean that I sholud lower it ?

> Oh, and there's no need to produce an AVI first, open the AVISynth-Scriptdi rectly in TMPGEnc.

You are right, but at the end of my avisynth script there is a Trim istruction
yhat TMPGEnc. seems to ignore :(

First off, I thought mpeg block sizes were in multiples of 8, not 16, I could be wrong.

Also, I wouldn't use a minimum bit-rate of 0, if I want max quality, I do min and max of 8000 in tmpgenc, because thats the max value, although it is my understanding, DVD format supports up to 9000? Is this not correct?

You're idea of adding a black border is a good idea, I've wanted to know how to do that without simply cropping or letterboxing in Flask. Now I know I can use avisynth to do it. The reason, is becaues the overscan on most TV's is too aggressive, and I have AVI's that play perfect on my computer, but the subtitles, get cut off on the bottom and sometimes at the edge of the screen. So your idea of adding a black border is good, don't assume that TMPGenc will encode and center everything properly, because it will still cut things off if they are close to the edge of the screen on your computer. Some TV's are worse than others of course.

Also, it is my understanding that CQ looks better than CBR, and is smaller too. I haven't been able to tell much difference, because so far I've only been encoding Anime, so the quality isn't super great to begin with.

> First off, I thought mpeg block sizes were in multiples of 8, not 16, I could be wrong.

I found this information on the Avisynth user guide.
I used to make SVCD with the same concept, ie black borders,
so I can use the bandwith for something i will actually see.
The aspect size is sligthly off specs by it is unnoticeable.

During the playback on my TV I only see a small (couple of line) black line in
the bottom.

I will try to set the VBV size to 0 to see if TMPGEnc does it's job. :)

Thanks for your opinion.

> I choose that dimension because I want to make the borders size a multiple
of 16 which is the MPEG block size.

Yeah, that's right, but consider on: You are encoding with half of the full resolution, so 32 Pixels will become 64 while decoding. So it's posible to see black bars at the Sides of your Video. That's why i suggest you to use 336 instead of 320.
336+16=??? 352 ;)

> The resulting size is within the PAL Safe area anyways.

See what i wroth on top of this posting.

> but at the end of my avisynth script there is a Trim istruction
> that TMPGEnc. seems to ignore :(

TMPGenc will not ignore anything in a correct AVISynth-Script. Guess there's some misspelling inside the Script. Oh, and TMPGEnc is also able to do such cuttings/trimmings. (Advanced -> Source range -> cut editing

So do you lose any quality, when you add the black bars? Because the AVi's I encode are already 4:3, so if I added black bars, I would be shrinking the video, does that make for loss of video quality, or is it small enough to not really be noticeable?

I would much rather have a slight letterboxing effect, than to have parts of my video cut-off.

First of all Thanks to everybody for answering.

>So do you lose any quality, when you add the black bars? Because the AVi's I >encode are already 4:3, so if I added black bars, I would be shrinking the video, >does that make for loss of video quality, or is it small enough to not really be >noticeable?

I do shrinking the video ideed.
The material I'm encoding comes from Digital Satellite. so it is not always
comply to DVD specs, that's why I have to reencode it
I do shrink the video and I add the 16 pixel border.
The outoput play perfectly on my TV,there is not visible (at list to my eye)
defference from the source material.

>TMPGenc will not ignore anything in a correct AVISynth-Script. Guess there's some >misspelling inside the Script. Oh, and TMPGEnc is also able to do such >cuttings/trimmings. (Advanced -> Source range -> cut editing

I agree, the same script works as expected on VirtualDub, it is only TMPGEnc.
Very bizarre behaviour wich I'm still investigating, there is probably some
problem vith the VFApi plugin.

>Yeah, that's right, but consider on: You are encoding with half of the full >resolution, so 32 Pixels will become 64 while decoding. So it's posible to see >black bars at the Sides of your Video. That's why i suggest you to use 336 >instead of 320.
>336+16=??? 352 ;)

I did not understand the statement.
The width of the TV frame is still the same, there is only less pixels.
The size of 32 pixels at Half D1 is the same that 64 pixels at Full D1.
I do not see black bars, at least in my TV.

> I do not see black bars, at least in my TV.

On YOUR TV, OK. But if i would play your Disc on my TV, than it's an other story. The visible Area of my TV is arround 664x538 (Full-D1 PAL). So the minimum size for Half-D1 is 332x538 without black bars arround the Picture.

Thanks for the info.

I'll try 332x538 as you suggest.

I suggested 336x544 or 336x552

If you are Captureing From Satalite and file use a strange resolution Like 544+480 you can still author it to DVD and it Might work, The program i usually use to Author DVD"s DVD-Lab has features for Authoring non-standard resolution Files Like Satalite TS Mpeg2 streams which Might be something to try ......

Hi,

I have a problem setting Colors with Tmpgenc. I record MPEG2 File from my TV Card with Video Bitrate 9000 and Audio 224. This file i change to DVD which works out Perfect. Now i try to change this to MPEG1 (Non Standard) with Tmpgenc for my Pocket PC (Ipaq H2210). I take following Settings

Video= MPEG1 (Non Standard)
Size = 352x288
Video Bitrate= 600
Audio= 44100/128/ Joint Stereo
With these settings i get the best results for my Pocket PC and the File Size also work out Perfect (110 min Film = 580 MB)

The only problem is on my Ipaq the Colors are very pale like less Red. I tried to change the Red Colors during Encoding MPEG1 (in Simple Color Correction) and tried so many different settings but could not get the better colors. Otherwise the film is Excellent but the colors does not comeup right.
Has anyone a Idea...??

Bye

Well It could be because because your Bitrate is far too low for that Resolution.....

Hi Minion,

When I convert a DVD (with DVD2AVI+WAV) and have the same Resolution which i wrote above, the quality of MPEG1 (after encoding with TMPGenc) is excellent.
This Bitrate i use because i want MPEG1 for Pocket PC (IPAQ H2210).
The Only problem is with MPEG2 File which i Record with my TV Card (Cinergy 400)
and the Quality of this Orignal MPEG2 itself is excellent with 9000 Kbit Bitrate.

Any other Ideas ??

check out this site and tell me if any1 notices anything well weird
http://dvd.vcd.americancdduplication.com/

recognise the screenn shots??? take a close look at the 'mpeg setting' screen shot

is this company in anyway involved with tmpgenc??? if not well ahhh WTF!?!?

If they provided more details for the Video, GOP, and etc. menus, it'd be easier to see. Maybe they just used that one screen? Their first shot did not look familiar at all. Maybe it is fake program to steal money? Or maybe it's a bootleg...

yea the first screen i dont recognise, but the 2nd screen is tmpgenc down to a tee.

alotta gullible people would actually buy this as well at $50 a pop

hmmmmmmm, maybe i should start something like this, i like making money for doing shit all ;-)))))

Hmmmmm, i just tried that page again and its unreachable

Hello. I have a movie sized 712x400. It's in widescreen because it is wide and the top and bottom black bars have been clipped out from the video file. The characters look fine, they don't look stretched out. So what settings for Video Arrange Method in TMPGEnc should I select to maintain the widescreen? I want to make an XVCD. Again, here are the weird settings I use:

Output Size: 480x480
RCM: Constant Quality
Bitrate: 2520 kbits/sec
Motion Search: Normal
Video Arrange Method: Center (420x420)

The reason why I have the VAM at center is because the side won't go off the TV screen. But it won't work for this widescreen because it stretches the video to drastic measures! Should I make it 420x400? Please teach me how you make the calculations in easy steps so I don't have to ask again next time (I have another widescreen movie that I might need help with next time). Thanks! :)

Woops, I forgot to add. I need to add some subtitles to the video too. But, the subs have 2 parts, a SUB and an IDX file. The creator said that you need both in order to view the subtitles correctly and their filenames must be the same as the AVI file. While I know the subtitling process via Virtualdub, I don't get what to do with this SUB and IDX file. :( Help? Also, Virtualdub only accepts SSA files. :(

set ur source aspect ratio to 16:9(fullscreen keep aspect ratio) not centre

But I don't have a widescreen TV. And I need to keep it center at 420x420 for non-widescreen movies for overscans. So now I don't know what to do with this widescreen movie because setting it at that might turn out to be too wide.

i dont have a widescreen tv either, do u notice that nearly all dvds are 16:9 widescreen, you dont lose any picture with a dvd do ya, you just get the black bars at top and bottom of screen which is fine yea?

thats exactly what you'll get if you do 16:9 (fullscreen keep aspect ratio), i promise you, ive encoded many widescreen xvids with this method and i never get any cut-offs

try encoding a little 30sec segment of your vid (so you dont have to wait a long time for end result) with these settings and you'll c what i mean

Thanks, I'll try it. But will converting it that include overscans? Because I must leave a 30 pixel border on each site so my subtitles won't go off the screen...

if you use the standard templates with the settings i said b4, you shouldnt have any cuts what so ever, although i havent tried with subs =/, but that shouldnt really make a differance

also my non widescreen tv only overscans when i 'dont' use the settings that ive said b4, it could b ur settings causing the overscan

No. Before I was using one of TMPGEnc's default VCD templates. And most of the times, long subtitles would go off the screen. Therefore, I experimented and found that setting the VAM at center 420x420 works best for me. The subtitles stayed on screen.

I think I know what you mean by 16:9. Before, I selected 4:3 525 lines NTSC under aspect ratio. So now, I selected 16:9 525 lines NTSC. Is that correct? Also, would that selection work for a video with a size of 640x360?

I tried that option with the video 640x360 but the widescreen is not appropriate. :( The characters turned plump! Any suggestions?

for source aspect ratio there should be an option with just 16:9 (not 16:9 ntsc, pal, blah blah ect) then set the video arrange method to full screen keep aspect ratio

settings:
source aspect settings: 16:9 display
video arrange method: full screen keep aspect ratio

if you use standard templates and those exact settings you will have no cut offs

Then what is 16:9 NTSC 525 line do? They're both 16:9 so wouldn't it be the same? I would understand that 16:9 PAL is different and I don't use PAL...

Oooh! I get what you're saying. I had originally set SOURCE Aspect Ratio as 1:1 VGA. And then under Video Stream Settings for Aspect Ratio, I set it at 16:9 525 line (NTSC). Now that I know what the problem is, what should I set the aspect ratio under Video Stream settings?

Source Aspect Ratio: 16:9 Display
Aspect Ratio: ?
VAM: Full Screen (keep aspect ratio)

Sorry, even setting it at 16:9 Display doesn't work. The characters are too plump. Just a side note, I downloaded this movie. It's a DVD-rip. So wouldn't it make sense to set the source aspect ratio as 1:1 VGA

>The characters are too plump

but do you get any over scan?? is it fitting the screen??

>source aspect settings: 16:9 display
video arrange method: full screen keep aspect ratio
(use the standard templates)

if you use those settings and it still doesnt work, well im at a loss

i'll say this again i use those exact settings and NEVER get any troubles (cut offs, obscure picture ect ect). if you have actually done what ive said and you are having problems with cutt offs or whatever, then i dont know what it could be.

and by the way, if you dont already know this (you probably do) the coverted movie will have different resolution than the original movie, which may or may not be causing the 'plumpness' as you say, but if the movie is fitting the screen well i'd take plumpness over terrible overscan anyday

>Output Size: 480x480
RCM: Constant Quality
Bitrate: 2520 kbits/sec
Motion Search: Normal
Video Arrange Method: Center (420x420)

whoa whoa whoa, your output size is standard compliant ntsc svcd resolution, are you creating a svcd or a vcd? (vcd ntsc res is 352x240)

I'm creating an X(S)VCD where the resolution is 480x480. And no, I don't think there is too much overscan, or there is too little overscan that I don't notice.

Also, if I do this it works:

Aspect Ratio: 16:9 525 line NTSC
Source Aspect Ratio: 1:1 VGA
Video Arrange Method: Center (480x360)

It works perfectly well for some unknown reason. The reason why I set it at 360 is because the source video's height was also 360. It work well anyway.

>It work well anyway.

excellent
i was running outta ideas

Hi, I am trying to convert svcd (mpeg2) to vcd format using VCDTrick. It works great for most files. But I am seeing problems while multiplexing some of the files. While doing simple multiplexing, part of the file is missing. I am not sure the reason for this. I really appreciate if someone could help me on this.

Im Trying to install TDA 1.5 & Im getting error -

also error 1714

please help

many thanks

I'm new at this. I am getting mono sound from my encoding. Great picture but not stereo. I am assuming that I have to separate the audio, does TMPG do that itself first? What do I use to put the files back together afterwards. Not a natural english reader.

Well If your Source File is Mono you will never get True sterio..All you need to do is Choose "Sterio" on the audio Settings and you should get a sterio Mpeg file but if your source file is Mono you will get a Psudo Sterio File with the same Chanell being Played out both speakers.....

Hi, I'm a new user and I'm trying to convert a .wmv file to .mpg to put a small 320X240 video on my webpage to have a variety of available video formats for the user to view. I've already converted many of my .wmv files except one older file [bit rate: 235Kbps; 320X240; 20 kbps; 32 kHz; mono 1-pass CBR] that comes out pixelated and choppy. Is there an appropriate setting or filter for this bit rate? Thank you!

Well Choppynes could because you are makeing a Mpeg files with a different Frame rate as the WMV Files..Tmpgenc does not convert Frame rates Properly, Pluss a WMV Files at such a Low Bitrate is going to be Quite Low Quality and even Lower when encodieng to Mpeg at a Low Bitrate, so you can either Raise the Bitrate which will help or deal with it, You can"t expect very high quality when the source is a Low Quality format Like WMV...
