I have an AVI captured at double-speed. Can TMPGEnc create an MPG of it at
half-speed, effectively making the material run at normal speed again?

It would help to know what the frame rate is.

ASHY

Yes it is Possible But It would be hard to tell you how to do it without Knowing what frame rate the AVI file was captured to..You can make it run at normal speed without encodeing it, you can use a Little Program Called "Avi Frame rate converter"(Or something like that) that will change the Frame rate that the AVI file plays at, so if say the AVI file is 30fps and Plays at double speed you change the frame rate to 15fps and it will play at normal speed, then you can encode it to Mpeg with the "15fps(30fps internally)" setting so you would have a Standard compliant Mpeg file(Mpeg can"t have 15fps)..But then audio sync would be another problem...

Sorry -- the AVI is recorded at 25 fps. Do I have to use an external app,
such as "AVI Frame Rate Converter", or can TMPGEnc do it? Thanks.

What do you mean it is double speed? Is it playing too fast?
25 fps is the correct framerate for PAL VCD so what's the problem?

ASHY

Yes, I purposely created the AVI at double-speed, and at 25 fps.
I then wanted TMPGEnc to create an MPG at half-speed, that is,
to render the MPG by slowing down the AVI by a factor of 2, if
possible. The MPG would still be 25 fps, but every video frame
would perhaps be doubled, and the audio would also be synced.

You've lost me?
Does the AVI actually play at the correct speed now at 25 fps or is it playing at twice the speed at 25 fps?

If it is the latter then simply click the 'Setting' button where it says frame rate and set the frame rate to 25 / 2 = 12.5 fps then in the advanced options check the 'Do not frame rate conversion' box.

Be aware that halving the frame rate like this may cause the playback to be slightly jerky.

Out of curiosity, what was the point in what you did?

ASHY

Hehehe, okay, here is a better explanation:

The source material is recorded at 25 fps (PAL).
The footage of this source was from a machine playing at 2x speed.
Thus, the source material is showing footage running in fast motion.
Similar to a VHS machine that has recorded material in LP format.

If you play back this source material at half-speed (12.5 fps), then
everything looks normal again (except at a lower quality, naturally).
So, the original source (AVI) is 25 fps with everything moving fast.
I want TMPGEnc to create an MPEG1, still at 25 fps to be compliant,
but at half-speed, so the footage is played at normal speed.

Ok thats better.
The info above will do what you ask.

I downloaded a movie. When I try to make a VCD with TMPGEnc, I have no sound. Then, I make a WAV file with VirtualDub. There is a delay of 5-6 seconds between sound and image. I tried various things and, still no synchro. Anybody has any ideas, please ?

Virtual Dub seems to do this with AC3 audio..Use something different extract the audio from the AVI file, like "AVI-MuX", and after extracting the audio to Wav check and make sure that the audio length and video length are the same cuz it they aren"t you will have a Sync problem...

Thanks for the tip, but it doesn't work. Any other ideas ?

The following will only work if the audio sync seems to get prolonged/delayed more and more as the file is played.

With virtual dub open the avi(what i usually convert) and under AUDIO>>Select Full Processing Mode

then Select Conversion and select 44100Hz then OK and SAVE WAV when u convert with tmpgenc you should have complete audio Sync.

Unless the original video file has undecompressable frames in which i think it deletes or maybe skips and then the audio begins to get out of sync.

If the audio is only out of sync for the 2nd half you may try to split the mpg and just try to sync that part.

http://www.dvdrhelp.com/sync.htm for mpg audio sync problems

hope this helps

Thanks, but this is the way I always do it, but this time it doesn't work.

Monte-Cristo just make sure you have the CONVERSION set to 44100Hz or else you will still get audio sync problems even though you have a wav file.

If the audio problems persist check the video stream for errors with virtual dub if it has many messed up frames then download it again.

Does the audio get prolonged more and more as the file is played?

or is the audio sync off sync the same at the beginning as at the end?

your only choice if you really really want the file is splitting it into 10 minute files and syncing each of those parts with this guide.

http://www.dvdrhelp.com/sync.htm

Hi,
If I play the movie on WMP or Winamp, it's perfect. The sound is out of sync right from the beginning with VirtualDub at 44100. Thanks for the guide. I'll look into it.

so back to the issues of no sound...

i did use a wav file at 44100 and when i used tmpgenc i got the picture but no sound!!!

i browsed to get the proper audio file and went through the encoding process only to have no sound!

anyone help?

Are there any audio converters to change AC3 into a MP3 file? If so would it be able to be used as a plugin like SCMPX?

Whay would you want to turn AC3 into Mp3??? Mp3 will Not do you any Good if you are makeing a VCD or SVCD Cuz they use Mp2 audio..Headac3he can encode AC3 to Mp2(and mp3)...and no you can"t use it as a Plugin...

I'm not making a (S)VCD and I know, but thanks. I have a whole bunch of .avi's that are using AC3 audio and I need to compress it so like I can free up disk space.

AC3 audio is allready Highly compressed so encodeing it to MP3 will not reduce the Size very much, Why don"t you just burn the Files to CD-R, then you can totally delete the file...

Hum, well I'll still expirement. Hey what program will seperate the ac3 from this avi I have? TMPGEnc won't recognize the audio part so I can't parce it.

if when u browse for an avi file and the audio box does not automatically filled in, it is because u have changed your codec settings, maybe because u have recently downloaded a new codec.

to enable the sound box to fill in automatically when u browse for an avi file, do the following:

quit the wizard, and go to options, environmental settings, VFAPi plugin, and right click on 'direct show multimedia'. Increase the priority until it is at the top of the list. Now open the wizard and browse for the avi file you wish to encode, and the audio box automatically fills in.

Matt. If you have more problems with tmpgenc - go to: http://www.dvdrhelp.com/tmpgenc.htm . There is a problems section 3/4 of the way down the page!

I have a avi file and a sub-file that I want to convert to mpeg2 but how can I include this sub-file?

It depends on the format of the subs. If it's from VOBs then you can use VOBSUB and Virtualdub to frameserve the movie to TMPG.
If they are in another sub format you will need the Virtualdub subtitle plugin.
You may also need to convert the subs with Subadjust to the correct format and to adjust the timing.

ASHY

how to frameserve with vdub to tmpgenc? do i need a plugin? can't find any information...

argh, didn't mean how to frameserve with tmpgenc...sorry, i meant how to open the vobsub files with vdub---?

Follow the instructions when installing VOBsub.
Load the AVI into Virtualdub then Click Video>Filters and add the Vobsub filter.

I have multi-language vcd, left channel play chinese audio, right channel play english audio, when I watch vcd I need to munually adjust speaker to the desire channel. now I want to remake vcd for english only (left channel), please tell how to setup, thank you very much

I don"t think you can, Well not with Tmpgenc..You would need to use an Audio editor to Extract the english channel to a Mono track then convert it to a Sterio Track then Mux the audio back with the video..There are Probably many tools that can do this but I don"t think that Tmpgenc is one of them..and you do not need to do any Encodeing of the video Just the audio...

I have given you the answer to this question over a week ago. Please pay attention in future!
This is your previous post: Request - How to extract left channel from audio file No.34765

Here is the answer again:

Virtualdub will do the job nicely.

1. Load your VCD into Virtualdub.

2. Click 'Audio' then 'Full processing mode' then 'Conversion' from the menu.

3. Where it says 'channel' choose the channel you wish to save. I.E. the left channel. Click OK.

4. Next click File then 'Save wav' from the menu. Choose a name for the wav and save it somewhere. This will save the left track into both channels.

In TMPG:

1. Load your wav into TMPG in the 'Audio' field and check 'Audio only' as the stream setting.

2. Now encode. When TMPG has finished you will have an .MP2 file.

3. Go to File>MPEGtools and load your VCD into the the Video field of the
simple multiplexer'
Load your new Mp2 into the audio field.
Choose 'MPEG1 video cd' as the 'Type' then name your output and click run.

4. When TMPG is finished you will have a new VCD with just the English track.

I have no ides why this is happening but when I encode an avi file into a standard vcd 1150 cbr or even when i use a lower bitrate of 1000 cbr.

I leave my computer unattended when it is encoding and when i come back to use it Tmpgenc has closed but the file that it was able to encode before it closed is on the hard drive in usable condition it always happens at different times sometimes it encodes 6 minutes or 45 minutes and I have no idea why it happens because I don't receive any error messages.

I have encoded many mpg files and didn't have any problems before this problem has been bugging me since yesterday.

Any help is appreciated.

I have an ASUS A7V333 AMD athlon xp 1800+ 256mb ram

I too have experienced this problem. I have yet to get an answer from anyone but I have narrowed it down to encoding certain divx files that I've downloaded. What I have found is that the encoded video is truncated about 2 seconds. Is this the case with the files you've been encoding?

My system is an ASUS A7V8X AMD athlon xp 2400+ 1.0gb ram.

Wayne what do you mean by truncated?

I checked the video for errors with virtual dub and it's fine absolutely no errors and I extracted the audio as a wav file before encoding.

I tried getting the free verion of tmpgenc and encoded with it yesterday only about 45 minutes and it did not shut down. I am not sure if it was just luck or if it was the tmpgenc i had was flawed.

but this has actually happened before and i just replaced tmpgenc and it seemed to go away but it reoccurs every so often. I am pretty sure it's a windows setting or something because when i have problems encoding a certain video if I just reencode it again it will usually do it fine the 2nd time so I don' think it is an error in the video.

Maybe but not likely if you have ever used a program IOLO System mechanic which I have used you can adjust a setting so that non-responding programs will be automatically shut down. I used the program and turned of that setting.Maybe you have used it before to and I wa thinking windows might think tmpgenc is non-responsive sometimes.

I have seen when tmpgenc closes for no reason and I was surprised I was sitting b the comp and I saw it just close as if i had aborted and closed it myself or also even stranger sometimes when I click start encoding or any other operation it will close itself with no error message.

I have windows xp proffesional :)

Yup have the same problem here...

OS win2k
Mb Gigabyte 6vtxe
P3 700

For me TmpgEnc will close for both single avi conver or batch avi convert. It is an immediate close not 1 minute or 45 minutes...

Am looking for other software to do the job...

Make sure your computer's hard drive is defragmented because I read in another post someone solved their problem by defragmenting the hard drive.

It might be causing some of the problems.

Although I have already converted this large avi VHS captured file (19GB), and it had converted OK a couple times with other times reboots and/or errors. When I finally thought that I had achieved a good result, DVDMAESTRO is giving me the ÁÕhis video bitrate is too high according to the DVD standardsEerror and stops building the structure. Then I had to try to reconvert reducing the bitrate and then is when all my actual problems started. TMPGE stops converting on 100% of my attempts, in spite of all changes I have made. It is been two weeks now over the same problem. The most common errors were:

Read error occurred at address 00483F5D of module 'TMPGEnc.exe' with FFFFFFFF.
Read error occurred at address 0049A567 of module 'TMPGEnc.exe' with 333231D4.
Read error occurred at address 00499775 of module 'TMPGEnc.exe' with 24232228.
Read error occurred at address 00482408 of module 'TMPGEnc.exe' with FFFFFFFF.
or
Illegal floating decimal point calculation order.
or
At address 4090544, Read error occurred against address 4090544.

My last tried setting is a 2-pass VBR with 3400MB average bitrate with maximum set to 6000MB and minimum rate set to 0, NTSC, High Quality motion precision, DC component 9 bits, YUV 4:2:0, ratio 4:3, VBV buffer 0 (automatic), sound LPCM stereo, no closed GOPs.

I believe that the ÁÕoo high error rateEwas given because the movie was compiled with TMPG set to a maximum of 8000MB bitrate. If that had happened (on a peak) and was added to the LPCM bitrate, which eats bandwith, that could have reached the DVD upper rate limit.

I desperately want to save this graduation tape, any ideas are welcome.

My hardware is a ASUS A7N8X with XP2100+, Corsair Xtreme DDR2700, video ATI 9700PRO and 450GB of HDs, the biggest one is the 200GB Maxtor Every, very fast one E SONY DRU 500A, all with XP PRO.

My TMPGEnc is a registered copy. TMPGEnc does not respond to my inquiries.

I"m not surprised that Tech support doesn"t reply, they are Dick heads , after they get your Money that is the Last they want to hear from you unless you want to spend more money..I don"t really know exactly how to fix the errors you are getting ,But I do have an idea as to how to fool your DVD authoring Program into thinking that the Bitrate is Lower than it really is, there is a Program called "DVD Patcher" that will Change the header of the File so that it shows the Bitrate is whatever you want..I use it for Authoring SVCD"s that have over the SVCD Standard Bitrate so that the audthoring program thinks the Bitrate is standard..You can also use it to Change the header so that the Resolution and aspect Ratio are seen to be different than they are..But if Your authoring Program actually analizes the File for the Actual bitrate then this will not work, and Might not work even if you Do lower the Bitrate in Tmpgenc Because Tmpgenc Has Really Really Bad Bitrate controll, I have had SVCD files set at 2500kbs that Tmpgenc encoded But after encodeing I put the File in a Bitrate Viewer and the Bitrate has spiked up to over 5000kbs..When I need Realy strict Bitrate controll(And awesome Quality) I use CCE SP to encode to Mpeg2 cuz it follows the bitrate exactly as you set it and produces exelent Quality and is Up to 5 times faster than Tmpgenc and Does up to 9 pass encodeing...But to get rid of the errors you are getting you might try Frameserveing the source file to Tmpgenc with something like Virtual Dub or AVISYnth....

Thank you Minion for your kind answer. I saved it for future reference.

Yesterday night I had a miracle over here and I could find were problem was. I had been around this problem for more than a week. Because the hard disk where I am storing the avi is new (I mounted it on Feb 08), I could never imagine that the problem was fragmentation! Can you believe that? The 19GB avi file was 68% fragmented, causing TMPG to either reboot or cause those read errors. It took me hours and 3 pass to defragment the disk. Today I was able to compile the DVD, burn and test it, and it came out just perfect! To get rid of the ÁÃit rate too highEI encoded selecting on the Á®PEG Setting -> Rate Control Mode -> 2-pass VBS(VBR) -> Setting -> Maximum Bitrate 6000. I choose Average Bitrate to 3400 to fit the 1:53 tape below the 4070MB file size mark. If you leave the Maximum Bitrate on its default, i.e., 8000MB, and you are encoding your sound track using LPCM, the two bitrates combined, during peak video bitrates, can cause the excess bandwidth. Limiting the Maximum Bitrate to 6000MB (or 7000MB) avoid that to happen. Other option is to keep the Maximum Bitrate at 8000MB and encoded the sound using MPEG. The collateral effect is that your players legacy compliance will reduce.

Thanks,

John

You see, I'm going encode a SVCD. I'm going to encode the movie with 2520 kbps CBR.
Will the output get better if I chose Normal, High or Very high instead of Fast in the motion search precision field?
I mean, I'm using the highest bitrate so the motion search precision will not have any noticeble effect, right?

/david

Of course it will make a difference.
How do you expect TMPG to allocate the bitrate to each scene correctly if it doesn't look for where the motion is in a frame? The higher the setting the more accurate the search will be and 2520 kbps CBR is not the highest bitrate or is it even that high anyway.
My advice is to use a VBR setting, the best being 'Constant Quality(CQ)' and raise the bitrate.

Set it to 'high'. This will give a noticable improvement over the 'normal' setting, but don't bother with 'highest' as there is no improvment over 'high' except for the dranatically increased time it takes to encode.

I have created a d2v project file in DVD2AVI and a mpa sound file was created automaticlly.
Then I got to TMPGEnc and open the d2v project file and the sound file.
And when I save it as a AVI file I don't get any sound in the file but when I save it as a MPEG file I get sound.
What's wrong?

What compression setting did you choose for the AVI audio?
In any case you should have created a wav for the audio not an Mpa file.

ASHY

MP3, 128kBit/s, 44,100 Hz, Stereo

I have a problem. Everytime I click on "Browse" to locate my AVI as the audio source, I get back a message saying, "Cannot open, or unsupported". I dunno what to do , now. The video was okay, but the adio source wont open. Can someone please help me??


Please email if you can help.

Generally speaking you should Extract the audio from your AVI files to a WAV file then use the wav file as the audio source..More and More poeple are useing AC3 audio in there Files especially with DiVX and XviD file downloaded off the net and Many encoders have major problems with AC3 Audio, so use something like "Virtual Dub" or even Better "AVI-MuX" to extract the audio to WAV format and use that as the audio source...

I was wondering if any has experienced the video playing great and then 30m or so into the video breaks up here and there and then returns to normal. I can't figure it out and need some help. Any ideas?

Does it only happen when you burn the mpg file to vcd or is it in the actual encoded file? I had a problem like this in which when I burned vcds about 30 or 40 minutes into it the video would get very glitchy and blocky. In the end I realised it was the brand of cds I was using (Imation). Now I use Verbatim cds and I can say that they are awesome.

Guess what type of CD's I'm using? IMATION lol, they glitch...
not to bad but they do.
What's with that anyways?
Anyhow I'm gonna pick up a dif brand tomm.
Later.

Well this happens when you use Crappy Disks and when you burn on to high of a Burning speed, if you are useing really cheap CD-R"s then I wouldn"t Burn at higher than 4+ speed, I use High Quality TDK Disks and I don"t burn at faster than 8+ speed , Cuz even with High Quality disks you will get Problems burning on High speed...

I agree with Minion. Don't burn at high speed. Some cheap disks also cause problems.
The best disks I have found, and have noticed this is agreed with in many other forums, is the brands made by RITEK such as DATASAFE.
This goes for both DVDR and CDR. These disks are highly reliable and give great performance regarding playback.


ASHY

I forgot to say it only breaks up when I play it in my DC (dreamcast)
Yes that's my movie player. I think it doesn't have enough power or something.

Are you using the crappy Dreamcast VCD player software or are you using Gyplay?

ASHY

Holy shnikes man.....I am using Imation cds as well. I only buy them cause I thought they were good cds. They seem to scratch less easy than others. WTF!?!??! So it is the cds none-the-less. Looks like I need a new brand. I get them at a heck of a rebate here when they go on sale. NOW WHAT DO I BUY INSTEAD??? Thanx for the help.

What about memorex......they r fairly cheap in price but i think they tend to scratch easily. What about Maxell. Or how about Fuji?

I use GypPlay, but i'm going to get a dvd player here soon, and make vcd's.
Can't stand those break up's. BTW tested a "TDK" brand cd-r on DC, same result's as the "Imation"

Well then the Problem is Probably your Dream Cast...You can get a DVD Player that Plays Most Formats For well under $100...Maybe it is time for an Investment..

Well i bought some Verbatim DatalifePlus and burned the VCD part one at 4x with my Liteon 40x burner. Still i get blockyness. Not at same parts though as before. Maybe its the VCDEasy program when i add chapters. It could be the culprit???

GUESS WHAT.....ITS VCDEasy PROGRAM. Its making my hard work turn to krap. So much for adding chapters!!!

I use VCDEasy with Most of my Non-standard SVCD"s and Have never had a Problem with it..Did you burn at a VERY Low speed??? and there are Lots of other Programs that will add Chapters besides VCDEasy, Like Most Ulead Authoring Programs...

Could you give me exact names of some of these programs? I would like to keep chapters but VCDEasy is not working well for me. I burned the one test VCD at 4x on Verbatim DatalifePLUS cd-r's and they got blocky on me when adding chapters. I am using a LiteON 40x burner. I then burnt the same VCD but at 24x with out chapters and it played perfectly the whole time.
