AVi to vcd files

[angelus214]

hi all

new to the vcd world (jus figured how nero works it). Ive been trying to write some of my newer files to vcd. But the files get frame sticky in windows media player and the same thing happens on a dvd player. for example if there was a frame of a man running switching to a frame of a horse running the man frame would still be there till the horse frame had cleared it piece by piece. thats what happens in wmp and on the dvd player. ive tried writing at lower speeds and getin a new version of the file but it still dont help.

the only way ive found to play them on my pc without this happening is by using video lan client however you cant put that on dvd players. any ideas how i can solve this?

thanx

Hi angelus214,

Welcome to the forums.

Try scanning for, and fixing them i.e. deleting video and audio, with VirtualDub.

I'm not saying that's the problem, but it's a possibility.

[daamon]

thanx for the info i appreciate it but there is another small problem. i dont have the faintest idea how to use virtualdub ive downloaded it but id appreciate a small tutorial if you know how.

1. Download the 1.5.10 version of VirtualDub (that's the current "stable" version).
2. Create a new folder on your hard drive - I've creatively called mine "VirtualDub".
3. Copy the files form the zip file into that directory and double-click on "VirtualDub.exe" to run the app.

4. Click menu options: File -> Open video file
5. Click menu options: Video -> Scan video stream for errors

Get that far and report back on what it says...

I also found this guide - the title suggests it may be useful, but I've not taken a look.

i scanned it and there appears to be no errors however when i loaded the file it did say something about the audio header and that it could rewrite it but that would introduce 40000+ ms of skew

[angelus214]

actual message was

virtualdub has detected an improper vbr audio encoding in the source avi file and will rewrite the audio header with standard cbr values during processing for better compatability. This may introduce up to 42197 ms of skew from the video stream. If this is unacceptable , decompress the ENTIRE audio stream to an uncompressed wav file and recompress with a constant bitrate encoder (bitrate 127.0 kbps 16.5)

[redwudz]

VD is correct. MP3 VBR audio is a problem with many encoders. If you save the audio out as a WAV and use that file as your selected audio in your encoder along with the original video file this will solve that problem.

[jchristl]

I've got the same issue as he does. Except mine says the skew is 7200 ms or so. I've got this AVI and all I want to do is split this thing apart. I don't even know if I want to create a DVD or an SVCD.

How to I get the Audio out of this dern thing?

Thanks

[angelus214]

ok ive stripped the audio how do i strip the video and put them together using virtualdub and how or more importantly what do i use to encode the audio wav file i created

[daamon]

Hi angelus214,

So you've got original_video.avi (I'm assuming it's AVI as it has VBR MP3) and now you also have audio.wav.

When you're creating your VCDs, use the video file for the video and it'll probably default to that for the audio too. Change the audio source file to be the WAV file you stripped out and make VCDs as you've done before.

Good luck.

[angelus214]

yeah ive got the original video file bigredguy.avi but i usually just drag the file onto nero to write can you recommend a vcd creator that gives you and audio source option. and a quick tutorial for it or does nero offer this and im just thick?

[redwudz]

angelus214, In my opinion Nero doesn't do well at encoding. You can download TMPGEnc and use that for VCD encoding and it will do a much better job. Lots of guides for it, and for VCD, it's freeware. Just follow daamons instructions.

[daamon]

Encode to VCD with TMPGEnc - free for VCDs.

I've created VCDs before with VCDEasy (an older and free version than the latest) and been happy with those.

Hi angelus214,

Iwould also like to point out to you a very easy to use free program with which you can convert an AVI(Xvid/DivX)file to VCD. It's called Avi2Dvd.

[angelus214]

ok guys maybe im doing something wrong but it didnt work. in tmpgenc i selected the video file as video source and the wav file as the audio source and encoded some of it and it still skewed in windows media player. the only thing i can think is that i completely remove the audio from the original video file cause i copied the audio from the video but i dont know how to seperate just the video (no sound). any ideas?

[redwudz]

When you open the original file in VirtualDub check 'File Information' and see if the video and audio length are the same. Do the same thing with the WAV file. All files should be exactly the same length. If they're not, you will need to adjust them. That's more complex.

It should make no difference that the video file still has the VBR audio in it. When you select the WAV file for the audio source, that's the only audio the encoder will see.

[angelus214]

video length 1:00:59.03
audio length 1:00:59:00

thats the length of the original video file with vbr audio in it.

wav file length is 60:59 (cant get it more accurate than that)

so whats that mean?

[daamon]

so whats that mean?

I'd say that that means the video and both audio files are all the same running time. The ".03" at the end of the video is 3 frames.

TMPGEnc has a "feature" in it (or, at least the version I use does) as follows:

1. Select video file.
2. Select different audio source.
3. Select encoding template - VCD in your case.

After step 3, TMPGEnc's quirk kicks in and changes your audio source to that of the video file. The above is quite possibly the steps you took, and hence explain your skewed audio - you're still getting VBR audio from the source file.

To get around it, do step 3 first then select the video file and different audio source.

Hope that helps...

i got version 2.524.63.181 core version 2.04.169 is that your version?

[angelus214]

ohand what template do you use

when tmpgenc loads it askes which format id lie to use i download one which i use "KVCDx3-MPEG-1-PAL.mcf" it doesnt use the audio and then i click the video file and the audio file.

do i need to encode the audio file with something coz i just extracted it from the video file and it said that it needed encoding with a constant bit rate encoder but i dont have one

[redwudz]

For audio select 'MPEG-1 Audio Layer II'. If it's not shown, go to 'Other Settings' at the bottom of the wizard 3/5 screen, click on 'Audio' and select it under stream type, then Sampling frequency of 44100. TMPGEnc is the 'Constant bit rate encoder'. If you are not using the wizard, the same setting is at the bottom of the main screen under 'Setting'.

[daamon]

i got version 2.524.63.181 core version 2.04.169 is that your version?

Mine is a bit older: 2.52.34.129, Core Version: 1.83.129

ohand what template do you use

I've only ever created straight VCDs, no variants, and so I use the VideoCD (PAL) template.

redwudz has covered your audio question.

[angelus214]

hi again all, just to let ya know i cracked it. decided to check what compression the files that work in wmp use, using gspot. and found that compression on tmpenc and then saved the file with the ripped wav files and hey presto. thanx for all the help

[daamon]

No problem. Glad to be of help, and good to hear you're all sorted...
