I've been searching long for this, and I guess I'm just not good at searching. My scenario is this:
I can capture with iuVCR (as well as Nero Vision Express) into huffyUV format with PCM sound, both generating about 1 or 2 dropped frames for every 20 minutes of recording, which isn't bad to me. I don't care to lessen the dropped frames during capture, what I want to know is after I open the captured file up in VirtualDub, what exactly do I do there? As til now, I have been doing the following steps in order, all with VirtualDub:
1) Save Wav of the audio stream onto harddisk
2) Find and delete the dropped frames in the video file, saving this "cleaned" video stream onto harddisk
3) Opening "cleaned" file, and muxing it with the previously extracted audio track
4) changing the frame rate so that "video and audio durations match"
5) applying XviD compression, and project is done
Up until now, I have been getting pretty good files, but I'm confused about the dropped frames. Right now, I capture at 29.970, but end up with XviD project's that are 29.951 or so fps. Before I delete the dropped frames, the frame rate is a perfect 29.970, but after deleting the dropped frames, the project is now 29.951 fps.
What I want to know, is this a similar method that y'all use for dealing with the dropped frames? Do y'all keep the dropped frames in, do y'all apply a filter to the file to deal with the dropped frames? I would like for the files to end up at 29.970, but I don't want to make the video the "master stream" as that will then skew the audio away from 44.1 kHz. Any comments/suggestions are welcome. Thank you for your time.
EDIT: Problem solved. :)
