Unless I press PLAY on the VCR before I start the capture, the audio will always lag behind the video depending on how long between the two steps. Say for instance, if I hit PLAY on the VCR 2-3 seconds after I start the capture in Virtualdub, the audio will lag behind the video for 2-3 seconds from beginning to end. If I do it the other way around, by having the tape already …

Instead, here are the technicals so you will at least know how it works and what issues arise as a result. I should note that I didn't devise the VBR scheme; I simply reverse engineered it from the Nandub output when I started receiving reports that newer versions of VirtualDub suddenly were not handling audio sync properly on some files.

I've been capturing Babylon5 on Sci-Fi, and I've been having problems with the audio sync. I capture video with low-motion DivX at 6 mbit/sec, and PCM audio at 22 kHz/16-bit/stereo (real-time MP3 compression crashes VirtualDub for some reason). After this, I do one of the following: - For a...

The audio isn't in sync in the capture file. It's what we get for putting audio and video capture on separate clocks. If you are running VirtualDub 1.4c or earlier, check the Knowledge Base for a possible workaround if your sound card isn't very accurate. (This problem will be fixed in V1.4d.)

First convert your movie using Virtualdub to some other format and see if audio remains in sync. In my case I used x264vfw, but I guess it doesn't matter as long the audio stays in sync and DVDVideosoft can handle many formats as input. Afterwards I used DVDVideosoft Free 3gp convertor to do usual conversion to MP4.

An imprecise clock can be one source of problems, background task interference is another, and audio buffering is a third. A subtle fourth source of error is that the capture program can only service audio and video synchronously; in particular, if video takes a long time to compress, it can delay the receipt and timestamping of the next audio block.

If you had an delay between video and audio, and you have corrected the audio track, you must instruct Virtualdub to use this corrected track instead of the audio track that is in stored in movie file: Virtualdub > Audio > Audio from other file...: Then select the corrected audio track you have stored. Before saving, you should test the result.
Welcome to virtualdub.org! - virtualdub.org
VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images. I basically started VirtualDub in college to do some quick capture-and-encoding that I wanted done; from there it's basically grown into a more general utility that can trim and clean up video before exporting to ...
