Creating 48 frames per second footage

[Craig W. Bickerstaff]

This most recent weekend I was shooting a short film and because this camera I rented could over crank in any frame rate I wanted up to 60 I decided I would shoot 720p24 at 48 frames and convert it via an image sequence.
I discovered however that I could not make a 48 frames per second movie in quicktime pro 7 nor could I make a sequence setting in Final cut pro 6 at 48 fps.
Any ideas? I was really just trying to test the motion of the video but it ended up not working out, I guess it would be easier to just shoot a 60p short if I wanted to test high frame rate films.

FCP 6 only supports 23.98, 24, 25, 29.97, 30, 59.94, and 60 fps as sequence settings.

Quicktime Pro can use "Custom" frame rates, and accepts 48.000 fps. Just pick "Export..." and pick your video settings. The interface varies a bit based on your codec ... but wherever it shows frame rate options, just pick "Custom" and type 48 into the text box that appears.

Well, if you are looking to see if you like higher frame rate stuff ... then I suggest trying a variety of formats in any case.

Here is the thing ... 60p looks notably different from 48p, just like 30p looks different from 24p.

My preference in "high frame rate" is for 48fps, with a 360 degree shutter, which I think looks a lot like 24fps with 180 shutter.

Not the same mind you, but it looks good to me.

I've done 60p tests in the past but they were just "I have the camera for a few hours more I'll go outside and shoot stuff" I still haven't shot a short in 60p let alone 48 for that matter, 48 just seems more interesting to me but I will likely try both at some stage.
Maybe I'll do 48 if I gain access to a red since I used the EX1 and that doesn't shoot 720p48 I would have to shoot the whole film 720p24 convert it afterwards then add the externally recorded audio.

Craig - just shoot in 50p. You live in PAL land, the difference is negligible for your purposes, and the look will be not noticeably different. Then, if you want it to look like regular video or put it to DVD, you can convert 720p50 to 576i50 (does require a bit of an obtuse hack to do it straight on the timeline in final cut, without a full transcode. Take your 720p50 footage, use cinema tools to make it 720p25 footage, put it on an SD Anamorphic timeline and speed ramp it to 200% speed with Frame Blending on. What you actually get is 576i footage with different motion in each field, whereas if you drop the 720p50 footage straight into an SD timeline it just makes it progressive and throws away every other frame.)

I craig did you figure it out ?
i know that 50P would be easy , but is 50P a standard of DCI for digital release ?
if not i guess that only 48P is an option ....

Does exist any tool to add progressive pulldown to 48P and make it 60P?
Does exist any tool to remove frames and transform back 48P to 24P (just in case for film release of the project ?)
Does Blu ray accept 48P ? (or need to be 60P?)

i think if we can add pulldown , than even FCP can be set to 60 P and we should be good to go ...

thanks

It didn't work out, I tried a 48 fps custom export in quicktime 7 but it just gave me 24 fps anyway. I may have done it wrong so I'll probably try again in the future.
As for the rest I really don't know, if I ever get around to doing a test film I may just shoot 50p or 60p to make it easier on myself, it's unlikely I would put them anywhere other then online anyway.
