Hypothetical: HVX200 60fps to 24fps in FCP
I’m researching for an upcoming shoot and have a hypothetical question. The shoot involves intricate timing in and out of the sides of the 720p frames. We shoot with an HVX200 and prefer 24fps stylistically, but in the shoot we are considering shooting 60fps in case we need to slow down or speed up a clip to make the timing match perfectly.
I know the HVX200 can record at 720p24 on a 60fps timeline by writing duplicate frames, then deleting those duplicates when you transfer it digitally (I’m running on FCP 6.0.2), but is there a way to take true 60fps footage and convert it to 24fps in post and still maintain a true, crisp 24fps film feel? I tried a few different ways and every test gives me either humming frames on extreme action movements or a blurring effect on the edges.
Any ideas? Would something like Twixtor help with this? Anything in Motion or Shake I can use?
Thanks!

Or use the DVCPRO HD FRAMERATE CONVERTER in the FCP TOOLS menu. This is how you get GREAT looking slow motion.

[Dave]: Copy the clip in question for safety’s sake, open the copy in Cinema Tools, and conform it to 23.98.
That’s one of the things I tried, but it makes it slo-mo. And when I take that conformed 24p clip back into FCP, drop it in a DVCPRO HD 24 sequence and speed it 250% to bring it back up to speed, it does that humming/blurring effect that doesn’t look good. I also tried the DVCPRO HD Frame Rate Converter in FCP (which in essence does the same thing as Cinema Tools, I think) with the same results.

Wait…what are you trying to do? You said you wanted to slow the clip down…that’s what we told you how to do. Now you don’t want it slow motion? I don’t get you…
You have 3 frame rates…23.98, 29.97, 59.94…what are you trying to do to “speed up” or “slow it down” to match…what?

I apologize for not being more clear on my original post. It’s hard to convey the intricacies of my situation.
The reason we wanted 60fps overall was so we have the extra frames to make that really sweet slow-motion effect if we need to, but overall would like to keep the 60fps clips in real-time, and just make them look like it was shot in 24. We’d love to shoot the whole thing in 24fps for the film look, but with the intricate timing of the shoot, we can’t afford to shoot it at 24 and 60. It’s basically locked off with long one-take clips.

Good to know. Just wanted to see if it were possible, or if there were alternatives I wasn’t aware of.

Ok, so is there some reason why he can’t shoot at 60 and then drop frames down to 24?

He can, if he shot 24p at 59.94, and used Compressor to convert, or perhaps Reverse Telecine in FCP or Cinema Tools. Or he can drop the footage into a 23.98 timeline and render.

I have stayed out of this manly because most of the solutions do not look the same as native 24p footage.
Short of Shane’s note (rendering 60fps in a 24p timeline) – there is not really any way to extract the frames to properly get to 24fps without manually extracting the extra frames.
Conforming the footage will not give smooth motion.
you can try a reverse telecine but with out a dupe frame cadence CT often forgets what it is doing.
you can pass the video thru a Teranex or Ukon to handle the issue.gary adcock
