60p>24p

For fun, I shot a bunch of 720 60p family video yesterday with my 60D. (I normally shoot 1080p). I originally was going to just slow it all down to 40% on a 24p timeline but now there is some I'd like to play back at normal speed on the same 24p timeline. The 60p slowed down looks great. Problem is 60p played at normal speed on a 24p timeline looks like cr$p.

I'm using Vegas 10.d. I tried ticking each of the resampling options on the event. I'm not transcoding anything - these are 720 60p .mov files straight from the camera. I usually render (even my 1080p stuff) to a 720 24p 3.5Mbps MainConcept .mp4 encoded file.

Any ideas?

That needs Optical Flow (synthesizing new intermediate frames).

After Effects and Motion have this, and there are many other tools.

There may be some virtualdub/avisynth tools you could get for free (except for the learning experience).

BCC works right within Vegas 10 and has Optical Flow, though I haven't used it for this purpose.

You could also put it on the 24p, disable resample, and playback at .8 to tell Vegas to drop every other frame. It would be like you shot it at 30p and slowed it down to 24, which isn't that much slower. If its too stuttery you could play with motion blur too.

kairosmatt - how do I tell Vegas to drop every other frame?

You might want to test HDStreamTools, www.cinecomp.com ($90). They do a great job of converting 60i to 24p. The only problem is that you have to feed them AVCHD files, so if your canon is recording as MOV files you would have to convert those to 60p AVCHD before feeding them to HDStreamTools. I've tested the 60i to 24p and really liked the results. They also have an option for 60p to 24p.
