Parsing source faster than real-time playback?

[fvisagie]

Hi All,

I need to extract and save to disk the timecodes from a 36GB DV AVI and so far the DVInfo-based script actually seems to be coming along ;-).

Apart from extracting timecodes the script isn't used for anything else. I would prefer for it to run through faster than normal playback speed.

Other than using a player with sped up playback or doing a light-weight encode, is there some way of making AVS running at maximum processing speed by just "dumping its output to Null"?

Thanks kindly,
Francois

You could use VirtualDub and it's "Run video analysis pass" option in the file menu...

Use VirtualDub and run the 'Video Analysis Pass'.

Incidentally, here's a trick to speed up DVInfo: replace DVInfo(file) by
StackVertical(Crop(0, 0, 0, 20).DVInfo(file), Crop(0, 20, 0, 0))

Thanks, people!

ffmpeg -i script.avs -vcodec copy -an -f null NUL

also works very nicely. Especially for me wanting to invoke this via the Windows shell and being unfamiliar with VDub's command line.

See what I was needing this for :) http://forum.doom9.org/showthread.php?p=1317470#post1317470.
