Project setting
hi, im a bit confused on what would be the best comp setting for me to do a project.
i have some footage, all shot in 720p 60p. and i would like to have some regular slowmotion like 40% of the original 60p which is aprox. 24p, and also on some parts use twixtor to slow down even more, like maybe 10% of the original 60p.
so im wondering if i should have my project comp in 60p, and then just slowdown the clips to 40% speed and then throw some twixtor on the ones i need, or, have my comp in 30fps and drop frames from the 60p footgae, then just interpret the footage i want to slowdown to from 60p to 24p. and on the ones with twixtor get the interpreted footage of 24p and add twixtor.
im just confused because im not sure if will have any advantage having my comp with 60p if youtube and vimeo will drop it to 30fps anyway when i upload it to the internet.
ideally i would like to have my final comp in 60fps, and then have it converted to 30fps for the internet because the footage looks smoother with 60fps as it is videos of people doing tricks with bmx bikes.i hope i was clear, thanks.

If you want the slow motion to be smooth, you’ll want to be taking the 60 full frames, and slowing them down to play back at 30fps, or 24fps. Perhaps 30fps as you are doing sports. So, you need a 30fps sequence, so that your footage slows down…all 60 frames…to play back at 30fps. If you used 60fps in a 60fps timeline…it wouldn’t be slow motion. And if you slowed it..then you’ll be doubling frames…not smooth. So, 30fps.
Make the 30fps timeline. Right-click on the footage in the Browser and choose INTERPRET…and have it interpret it at 30fps. BAM…it’s slow motion…smooth slow motion.

yeah, but if i have a 30fps timeline, than all my 60p footage will be dropping frames to match the 30p timeline right? and therefore i will have a sort of a choppy video.
what i wanted to do is make use of the 60p footage, and in some parts of the video throw in some smooth slow motion playing it back at 40% speed of 60p (which is around 24fps) plus on top this make some super slow motion using a little bit of twixtor.
so what im wondering here is on how to make the slow motion with the best results.
is it better to just change the speed of the clip to 40%? or should i interpret the footage to 24p and then add twixtor if necessary??? -
[Willian Praniski] “yeah, but if i have a 30fps timeline, than all my 60p footage will be dropping frames to match the 30p timeline right? and therefore i will have a sort of a choppy video.”
30fps is hardly choppy. NFL Football is broadcast at 30fps. All that will happen, if you put your 60fps at full speed into a 30fps timeline is every other frame will be removed. Won’t be choppy at all. But if you want the 60fps stuff you shot to play back slow motion…SMOOTH slow motion, you need to use it in a lower frame rate timeline. 60frames at 60fps is 1 second. 60 frames at 30fps is two seconds…and slower. So slowing down 60fps to 30fps will be a .5x speed…and smooth. If you use 60fps in a 60fps timeline, and try to slow it down…then every frame is doubled in order to slow it .5x or more.
[Willian Praniski] “what i wanted to do is make use of the 60p footage, and in some parts of the video throw in some smooth slow motion playing it back at 40% speed of 60p (which is around 24fps)”
No, that’s more like a 60% slowdown. 30fps is a 50% speed, 24fps is slower…so 60% slower. If you slow it down to 24fps…and use a 24fps timeline, then things will looks “cinematic,” not smooth. 30fps is smooth. But you also cannot slow your footage down to 24fps, and have it play in a 60fps timeline smooth…frame will repeat.
[Willian Praniski] “so what im wondering here is on how to make the slow motion with the best results.”
I’m telling you. Use a 30fps timeline…slow your footage 50%…basically taking all 60 frames per second, and stretching it to play back…frame by frame…but at 30fps. FCP uses Cinema Tools and the CONFORM option to do this. It’s easier in PPro…and I told you how to do it. If you need me to do a video demo of that…I will.

ok, i think i got it.
so just to make sure i understood it right.
i will have a 30fps timeline, drop all my 60fps footage there, which will play at 30fps. and thenn on the parts i want to slow down, i take the footage i want, interpret to play at 24fps or 30fps. and then if i want to make a super slow motion i take the interpreted footage and add twixtor right???thank you so much for helping me out, i really appreciate it.

[Willian Praniski] “i will have a 30fps timeline, drop all my 60fps footage there, which will play at 30fps.”
Yes…you got it!
[Willian Praniski] “and thenn on the parts i want to slow down, i take the footage i want, interpret to play at 24fps or 30fps.”
30fps…so that it matches the frame rate of the timeline.
[Willian Praniski] ” and then if i want to make a super slow motion i take the interpreted footage and add twixtor right???”
That I’m unsure of how to proceed. I know that you can send it to AE, and use Twistor. If it sends it 60fps slowed to 30fps…I don’t know.

ok how do i convert 60 fps to 30 and keep it same speed…when i do this it looks choppy
-
Just drop the 60fps into a 29.97 fps sequence. It’ll look choppier than 60p because there are less frames. If you use a 30i sequence instead of a 30p…that might help not sure. Not sure the frames will get dispersed amongst the fields.
