Greetings.
I downloaded a Grateful Dead concert from YouTube.
The video is missing the last 2 songs & encore of the concert.
I downloaded from somewhere else the audio for the missing items.
The audio time is about 25 minutes.
I created an avs file that loaded three mp4 files from YouTube
with a total time of about 6+ hours.
ViDub Source Rate Adjustment says initially,
"Change so video and audio durations match 481.54fps".
After I edit down the 6+hours to about 29 minutes,
ViDub Source Rate Adjustment still says 481.54fps instead
of computing based on the new 29 minute length of the video
with the 25 minute length of the audio.
It seems to me that ViDub Source Rate Adjustment should
recalculate as the length(s) of the video (and/or audio) change.
I will also mention that -
ViDub would not properly dub the output I wanted.
ViDub would generate the video output but
would only process a few seconds of the audio ...
so I loaded the video output into ViDub and then
added the audio track - which worked fine ... |

Edits on the timeline take place after that adjustment option and also assume the audio is synced as they remove both audio and video together. The other way around wouldn't work.
Also, if you're seeing ~480 fps show up as the calculated length, it means that the audio stream that VirtualDub is seeing is much, much shorter than the video, so the auto-adjustment wouldn't work anyway. That option only works if the amount of audio and video is the same, and for some reason the source file is set to play one or both at slightly the wrong speed.
