Whenever I turn my VOB files into AC3s, and then open them in VirtualDUB via AVS, they have huge (as far as I can tell) file sizes. (15 MB for a 10 second video! :o)

Also, if the video is any longer then about 2.5 minutes, it expieriences HUGE audio lag. What am I doing wrong?

I've had this problem for a while, but now it is finally starting to bug me Grin

That's what compression is for, maybe you should read up on it (the FAQ).

I don't know but you should do problem #1 first.

I do compress (using DivX compression codec) but it still doesn't work very well.

However, it does reduce the size by about 90%. (The originals are nearly always above 100 MB)

Did you compress audio too? 3 minute Wav is a pain in the ass in the context of DivX compression....audio can take moe than video.
To compress the audio, click on Audio in Virtual Dub, then Full processing, then compression in Audio tab. Then choose the codec. The best would be Lame ACM that nate tells about in recording and compression FAQ.
Advices for installing it are in said FAQ.
For the lag, after you compress something, show us the sample. Maybe we'll find the way to kill it.

... Yes, compress the audio...

Typical wav bitrate of 1411 kbps * 10 seconds = 13.8 MB. Add video and you got your 15 mb in 10 seconds.

I'm addicted to games

start the divx pro trial, then select the "unconstrained" profile in the divx compression options.

edit: uh, dont delete your post after I reply! People won't know why the hell i told you that.

Hmm.. that seemed to fix my DivX problem... Thanks!

But the audio still has problems, even with the compression.

Okay... Its uploading to my site. The url when it is uploaded will be "http://www.zeldarevolution.net/ZoraHallsGlitchyHills.avi" according to my FTP thing, it should take 41 minutes from the time of this writing to upload. I'll edit this post if it finishes eariler.

EDIT: Its uploaded. The file is a .avi that has audio lag near the end.

I remember you had audio sync problems a couple months ago..

First off, you need to learn how to troubleshoot. I have no idea if the problem is in the source file, or in the final encode. Maybe you should tell us that first before we go farther with this.

And it would probably be a better idea to upload a sample of the source files of that 1:17 video, to see if others can reproduce it, or find another way around it.

Oh, and I get a "this avi file was not prepared for sequential reading" error when loading with media player classic. Just what are you doing? :-/ It still loads... but that shouldn't happen.

edit- You know what.. to save some time from going back and forth, here's what I want you to do:

- Download and install latest DGindex
- Put the dvd that has that clip in the dvd drive
- Load whatever vobs are inside into dgindex
- Try to make a selection of exactly what was in that clip
- File -> Save project and demux video
- Do not rename the files.

You should get an m2v and ac3 file. Upload that for us to try out. And you should try encoding it too.

I use DGIndex.
I get a D2V and AC3. Is that what you meant?

And I don't have that DVD anymore. I could get a new one if you want of me just messing up on tricks if you want...

I just made another video. It didn't have audio lag this time (I successfully compressed both the video and audio this time). However, when I uploaded it to youtube, the video conversion (to flash) failed. I tried uploading it twice, with no luck. That may mean something, but I doubt it.

The link below contains a .zip file with my most recent video's D2V and AC3 files. They are already renamed, though. If you need the one that is vob_numbernumbernumber instead, just tell me.

http://www.zeldarevolution.net/vob.zip

The video you watched with the Zora and stuff is really old, and made without Lame. I don't know if that is important, but I don't think it would be very good for working with...

My VOB files don't have audio lag. It happens when I open them in VirtualDub.

And what I do to make my videos is:

-record
-open vobs in dgindex
-rename vob######### to vob
-open vob.d2v and vob.ac3 in virtual dub via avs file
-resize
-compress on an unconstrained profile at 2048 bits w/ the divx codec
-compress with lame
-crop ends of video where necessary (to get a good video)
-save
-watch
-cry silently

A VOB is a container for m2v video and ac3 audio. What good is a d2v file without the video stream?

Quote:

The whole point was to get the source file. You encoded that zora video so you still have the source files somewhere.

Good, no more need for this thread.

WTF did you encode this with? It's impossible to play this on my computer, which is kind of hilarious, as every video from the site plays extraordinarily well...i have every possible codec i can think of installed. Even MPlayer and VDub won't play this!
I second ballofsnow. What the hell are you doing?

EDIT: Oh shit ballofsnow is right. I didn't notice one channel audio because i have a special mode in my speakers that makes even mono audio a stereo one...But after turning it off i can say he's right for sure.

Tell us every step you take when encoding. Also reupload the second video - maybe upload got corrupted.

Do you think the speaker problem is because of the audio setting on the Zelda game? I can change that from the main screen.

And I have no idea what I am doing wrong O_o That is why I am asking for help. What I do is--

Record using a DVD-RW
Open the Vob files directly from my DVD drive into DGIndex
Save project or whatever as "vob" into my Local Disk (C:) drive
Rename the weirdly named .ac3 file into vob.ac3. (its originally something like "vob126g3702.ac3"
Open my .avs file into virtual dub
Compress the video via DivX Codec at 2048 kbs on "unconstrained" profile
Resize the video to 320x240 via the resize file in virtual dub
Compress the audio with Lame
Save AVI as "whatever.avi"

Viola...

EDIT-- I don't think the upload got corrupted. YouTube also doesn't recognize it.

Ahhhhh. I think i got it. From the Compression FAQ:

Quote:

DGIndex will do the work of demuxing your run and, after a time, will finish and beep. From here, you will need to unzip and edit the vob.avs file. Open it in Notepad and change the C:\Program Files\AviSynth 2.5 ... lines to wherever you have your Avisynth plugins directory. If you installed Avisynth on your C: drive, these lines are probably already correct, and do not need to be changed.

Next, change the C:\vob.d2v to wherever you saved the DGIndex project file. You should not need to change this, either, if you followed my instructions earlier and saved the project file at the root level of your C: drive and called it vob.

Did you do this?
Also, do you have enough free drive space? I didn't encode DVD videos much (well, hardly at all :)), so i didn't run into a problem like this, but free space continously runs into programs way and gives many problems, so that might be the case too Grin

You do it all at once or in three steps? In the second case, either swap the order or do it once. More effective, faster and better quality that way.

Even so, if your player can read this, reupload.

Remember, you NEED files with audio (ac3) and video (d2v). Do you have them after the project?

Yes, I did that.

I'll go reupload right now.

And what do you mean by "swap the order"? And how do I do it all at once?

EDIT: OMG.... I just realized... I can't watch the video. O_O; I was able to just fine in Virtual Dub... I opened it in Windows Media Player, and the audio worked fine, but the video wasn't showing.

Any ideas? And does anyone here have MSN? Using MSN would be much faster.

I don't have it, sorry :-[ But that what's the forum for. Besides, other people can get into discussion and help you too.

Maybe try to encode the video with other codec. XviD or x264 for example.

By swap the order i meant: first resize, then compress the audio & video at once.

What about the free space? And you didn't answer me what files you get after saving the project...

And I get a "vob.d2v" and a "vob279572957297529.ac3".

Do codecs such as XVid work as good as DivX?

Sometimes they are even better. And x264 (h.264) rulez.

To do the both at once...first choose the compression for video, then for audio, and then save the video.

First, you need to fix the problem with no audio in the right channel, then you can try my H.264 guide. It's made specifically for Starcraft, but you should still be able to follow it since you've already got your avisynth script setup.

Note that you'll still have to learn how to encode to DivX/Xvid if you plan to submit to SDA. (or get Nate to do it..)

Hmm... XVid seems to be working... I got video, and no noticeable audio lag (yet). I'll be sure to post here if I need more help. x264 didn't work right.

And does anyone know the Double-Posting rules? Are there any? Forum double-posting rules seem to always change.

I'm reuploading the second video. It should be uploaded in about 45-60 minutes.

EDIT: Make that 15 minutes.

There are no rules set in stone about double posting, just use your common sense! Is double posting on a month-old topic ok? Yes. Is double posting on a topic an hour old, where you know people are going to check it again later, ok? No.
