Frame-rate Troubles!?!?!?

[puertorican138]

I have a 53 minute clip that has a 49.925 Frame-rate. When I change it to 29.97FPS in VirtualDub, and I check the file properties, the 29.97 frame-rate is 88 minutes and 19 seconds long!!! How did it get that long??? Can somebody show me the steps to convert this to another framerate properly. I've read the guides and I get so confused.



Any help would be appreciated 8) :P.

How did it get that long???

example- if you have a clip with 60 frames and the framerate is 30frames/sec. then you see that the clip is 2seconds long.

ok, now let's say you reduce the framerate to 15frames/sec. now instead of playing 30 frames every second, you're playing 30 frames every 2 seconds. thus making the clip take "4" seconds to play the 60 frames.

as you can see cutting framerate in half will double the length of the clip. there is really nothing you can do that is easy to reduce the framerate.

what's the hard way you ask? let's just say it involves "manually" taken out 19.045 frames out of every second of video then changing the framerate to 29.97 frames/sec, then streching or shrinking the audio to fit the new video.

If you decimate by 2, it'll be close to PAL. Maybe even close enough.

Thanks jkl, I've already found a topic that shows me this :P.
