Can somebody pls explain why the audio in my movie gets out of synch in the middle??? It was perfectly fine at the start then its gets delyed for 1 sec, in the middle.
First I tried use virtual dub to edit the movie, then I got this message.
VitualDub has dedected an improper VBR audio encoding in the source AVI File and will write the audio header with standard CBR values during processing for better compatibillity. This may introduce up to 15257 ms of skew from the vidio stream. If this unacceptable, decompress the *entire* audio stream to an uncompressed WAV File and recompress with a constant bitrate encoder.
After that I said yes rewrite the header.
then followed this procedure below.....I've done this a couple of times and it was all OK but now I'm worried that if I change the audio/interleave it might screw up the first part....PLS HELP
Converting .AVIs with VBR-MP3 Audio
Simply use VirtualDub to save the audio stream as an Uncompressed PCM (WAV) file as follows:
Load your original .AVI into VirtualDub
From the "File" dropdown menu, select "Save WAV" (Enter a new filename with a ".WAV" extender).Click on "OK"
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.
In the audio/interleave you can add/delete a delay for the sound in milliseconds. So, for 1 second delay, use -1000.
