Shot 60fps but metadata still says 23.98fps
Shot on the 7D at 60fps. I open the footage in Quicktime and it says the frame rate is 23.98.
We shot this to be played back in slow motion–and i know to comform the 60 fps clips to 24fps, but I’m confused as to why the clips (right from the camera) when played in Quicktime say they’re at 23.98.
Does this mean the footage wasn’t actually shot at 60fps? and i’m screwed?
Thanks.

I’m assuming you shoot 720p and not 1080p.
At 24p is it playing back in slow mo?
-
the clips are 1920 x 1080. they play at normal speed at fps.
i wasn’t shooting, but i do know the fps were set at 60, but is there something wrong with shooting 1080p at 60fps?
thanks

i’m afraid your assumption has just answered my question: you can’t shoot 60fps at 1080, can you? only 720.
i didn’t shoot, and we’ve never done 60fps. i know the camera was set at 60fps, but if your shooting 1080 then it must default to 24fps. is that correct?
so is the only solution now to slow it down in post, which will look terrible so there’s no point in doing so?
thanks

Nothing shots 1080p at 60fps, Unless you go to about a 100 grand camera (or a real cheap flip type camera)
-
there are plugins (that cost) that can do a pretty good job from what I have read. I think RE:Timer or something like that.
-
yep. as soon as you mentioned 720p i realized where we went wrong. lesson learned, and they’re always painful.
so now is there any decent way to achieve slow motion in post? I’m looking into twixtor but that’s pricey.
thanks again

Regarding you question about slowing footage down. Do you have FCP? I have had a lot of fun slowing shots down using Apple Motion and selecting Optical Flow as your method. Here’s a little demo I found
https://www.metacafe.com/watch/1270539/super_slow_motion_optical_flow_retiming/If you slow the material down to say 5 or 10% you can start to see really weird morphing-type effects that I just love for an avant-garde film I’m making. Two examples of what I have been doing with it here:
https://www.youtube.com/jonfelixfilms#p/u/2/BRWzM6AyBag
look around 2mins 8secs. This was super-8mm footage shot at 24fps and slowed down to 2fps.and here:

original material shot at 2fps, exported out to 24fps (so going way too fast), then slowed via Optical Flow in Motion to 1fps. -

You can’t set the fps on a Canon 7D, they are pre packaged with the size of the video. 1280×720 is either 60fps or 50fps. Are you confusing shutter speed as fps?
Also in case you are not aware if you choose 1280×720 60fps, then your shutter speed should be double the frame rate, so the nearest is 1/125th sec.

The problem was that we didn’t know you can’t shoot 1080p at 60 fps. Lesson learned! I know about the shutter speed thing–that wasn’t an issue.
What I ended up using for the slow motion effect was a plugin called Twixtor. Really impressive and intelligent slow motion plugin. Here’s the final video, all shot at 24fps and slowed down to, at the most, 50%.
