Why no interval mode or 1 shot in 24p?

Out of curiousity, what don't interval mode or 1 shot work in 24p? Is it something about the pulldown? Shouldn't they at least be able to work in 720 24pN since that just records pure frames? It's a shame as I'd really like to be able to do some timelapse stuff but it'll look odd at 30p when mixed with 24p. Is there any easy way to shoot 30p and 60p and somehow convert to 24p in post?

Hi David, I agree it's a slight bummer that interval work requires the camera to be in "video" mode. But, the fix is easy, either Mac or PC if you have After Effects.

Simply bring in that time-lapse/animation footage into After Effects and change the frame rate of that clip to what you want it to be (23.976). Make a comp at 23.976 frame rate and duration, drop the clip on and write that out as a new file.

Regards,
 
Thanks. I was thinking of trying the same thing in Combustion. Will the motion look better if I do 30p or 60p when converted to 24?
 
Since you're basically "assigning" a playback rate based on the time base you want, either 30p or 60p will look the same. 30p would be an advantage only if you need a bit more shutter open time when shooting, but otherwise they'll be the same.

The trick is to just ignore the actual fps when shooting and just "think" in terms of 24fps when plotting out how long something will take... if you want the sunset to be on-screen for 10 seconds, and it takes 20 minutes of actual time, your interval at 24fps would be a frame every 5 seconds.

Hope that helps...
 
One caveat... with After Effects you can literally tell the clip it's a different frame rate, this isn't a render or a frame-blending sort of thing... you're treating the QT like it's an image sequence, which has no inherent time-base in the first place...
