Steven P. Denny Posted September 9, 2010 Share Posted September 9, 2010 I have the Varicam 27H. We shot some footage at 24fps. Now the director wants the 24fps converted to 60fps! I think we're screwed? Though I have read many times that 720p format is always recording to a progressive 60 (59.94) frame tape format. Is there any way to convert this 24fps to a 60fps in post?

Premium Member John Sprung Posted September 9, 2010 Premium Member Share Posted September 9, 2010 Is there any way to convert this 24fps to a 60fps in post? Sure, no problem, it's called 3-2 pulldown. Most of what we did on film for TV went through that process, all the way back to Lucy. Any post house can do it. -- J.S.

Premium Member Phil Rhodes Posted September 9, 2010 Premium Member Share Posted September 9, 2010 Depends what they want, though. Is your director after a slow-motion effect? If so, look at Twixtor, or any of the other interpolating frame rate converters. Results can be eyebrow-raisingly good: http://vimeo.com/8574526 P Link to comment Share on other sites More sharing options...
Steven P. Denny Posted September 9, 2010 Author Share Posted September 9, 2010 Yes, Phil, they want to use the 60fps for slo-mo, just as we get when we shoot a 60-frame shot in film. I just did not think you could take the 24fps recorded video and overcrank it to 60fps in post without terrible flutter. Link to comment Share on other sites More sharing options...
Steven P. Denny Posted September 9, 2010 Author Share Posted September 9, 2010 Phil, I just watched the link at Is that 24fps video converted to highspeed? Amazing. Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted September 10, 2010 Premium Member Share Posted September 10, 2010 If it's slow motion you want, the best of the bunch at the moment is Arri's Relativity software. FotoKem has it. -- J.S. Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted September 10, 2010 Premium Member Share Posted September 10, 2010 Is that 24fps video converted to highspeed? Yes, but fire is a fairly friendly subject for it - if you know what artifacts to look for, you can see it warping away, but then fire is a fairly "warpy" thing anyway, so it isn't too obvious. Still, with manual guidance and really good software, you can get quite astounding results out of this sort of thing. That example was just "full auto" mode, give or take the ramp at the beginning where it originally failed badly on the rapidly-expanding early part of the explosion. It isn't hard to look around and find examples on Vimeo or Youtube of this sort of thing choking badly on certain types of motion What I'd do is to do my edit with cheap, low-quality frame doubled versions, then get someone (can't think who you'd possibly use, ahem) to do the HQ versions with manual hinting and everything.
