avi splitting with virtual dub

[apocX]

Hey, I tried to cut the credits out of a movie so it would fit on one disk and that worked fine and the new file I created has flawless audio but the video skips very badly. I followed the tutorial flawlessly whats the deal?

THanks,

ApocX

1) Did you set BOTH "Video" and "Audio" to "Direct Stream Copying"?

2) What version of VirtualDub are you using?

[apocX]

yep, I set them both
1.4.7

[setarip]

Version 1_4_6 through 1_4_8 were buggy in this regard. I'd suggest that you download the latest version 1_4_10, or one of the older, proven versions (I continue to use version 1.4D)...

Let us know of your success ;>}

[apocX]

Good deal, I got 1.4.10
No more skipping!
BUT.... now I have audio out of sync. hopefully this wont be too hard to fix tho

Here is the error I get when I open the AVI file:

VD has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header w/ standard CBR values during processing for better compatibility. This may introduce up to 20894 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress w/ a constant bitrate encoder. (bitrate: 127.8 ± 13.1 kbps)


Thanks,
Apoc

You've got an AVI file that has a Variable Bit Rate (VBR)-MPEG Layer 3 (MP3) audiostream, which has to be converted to a Constant Bit Rate (CBR). Do the following:

Simply use VirtualDub to save the audio stream as an Uncompressed PCM (WAV) file.
Then set "Video" to "Direct Stream Copying"
Then save the .AVI as a silent .AVI (set "Audio" to "No audio" after you've saved the WAV file).

Then close VirtualDub and restart it
Set "Audio" to "No audio"
Load your silent .AVI
Set "Video" to "Direct Stream Copying"
Under "Audio" click on "WAV Audio" and load your .WAV
Set "Audio" to "Full Processing Mode"
From the "Audio" dropdown menu, select "Compression" and choose the appropriate .MP3 settings. Click on "OK"
From the "File" dropdown menu, select "Save as AVI" and save your file with a new filename.

Again close VirtualDub and restart it
Do your cutting and save your new, shortened .AVI with a new filename.

Be good enough to postyour results...

thanks setarip, you are helping tremendously, I'm at the part where I seletect the .mp3 settings (sorry I took so long, i had a phone call) what should I select?

[apocX]

I'm guessing MPEG layer 3
but can you confirm this? Thanks

[apocX]

well I did as you said and it worked great BUT the final file was 1.07 GB
i guess the conversion to .wav ???


thats w/ me seeing the compression to MPEG layer 3, i assume thats right...

[setarip]

"thats w/ me seeing the compression to MPEG layer 3, i assume thats right"

Yes .MP3 and MPEG Layer 3 are one and the same. Once you've selected an MP3 setting (e.g. 44,100Hz, 96Kbps or, if need be, 48,000Hz, 96Kbps) and resaved the file, the filesize will be MUCH smaller...

[apocX]

alrighty, how do I do that?
THanks again man, your a great help

[setarip]

As I mentioned in my earlier post, "From the 'Audio' dropdown menu, select 'Compression' and choose the appropriate .MP3 settings. Click on 'OK'"
