Changing frame rate with Gordian Knot?

[boosted]

I have a TS capture of the show 24. Fox broadcast it in 60p (59.94 to be exact) and I'm trying to convert it to Xvid in either 60p or 30p. The problem is, GK's front end won't recognize 59.94 fps and the resulting video ends up looking like slow motion. I tried using avifrate to change the frame rate, it made it worse. I tried to edit the d2v file to 30p to try and fool GK to encode it at 30p then use avifrate to change it back to 60p, didn't work. I know VDub can drop every other frame, but I don't know which file and where to edit it after the job in GK have been queued. Any ideas? Perhaps I'm doing this totally wrong?

Hi-

I've never captured anything in my life, and have no idea why your 59.94fps AVI gets played back slowly (assuming the source plays at the right speed). Evidently the framerate is getting reduced, but without the duplicate frames being removed. Or maybe your computer just can't keep up with decoding Hi-Def 60fps AVIs. I do know, however, how to get it to play at the correct framerate.

If you want 29.97fps, just add:

SelectEven()

into the GKnot generated .avs. If you want 23.976fps (much more likely if this is show is film), then, remove the "#" from in front of the Decomb LoadPlugin up near the top of the .avs, and then further down edit the .avs by adding this:

SelectEven().Decimate(5).

Save the .avs, and before doing the encoding, open the .avs in VDubMod and first go File->File Information to confirm the framerate, Then find a place where there's movement, and advance a frame at a time to confirm that there aren't any duplicate frames, and that there aren't any frames missing.

You're using 30p and 60p incorrectly. It might be 720p 60, for example. When talking just framerate, it's in FPS. I'm taking your word for it that the show is broadcast 59.94fps progressive. If it's interlaced or at a different original framerate, then those script edits won't work.

Thank you so much for the reply manono.(again) It worked perfectly as advertised. SelectEven().Decimate(5) reduced the framerate to 23.976 without duplicate frames and no missing frames. Movement is smooth as it should be. Just as a test, used SelectEven() by itself, duplicate frames shows up every 5 frames as it should be.

About 30p and 60p, you're absolutely right. I think I was frustrated with the conversion and came up with my own shorthand. Now I can't remember why I used it that way. lol
