Hi there
Youtube and Vimeo support 60 frames per second.
Now I am thinking about using 60 frames for my next timelapse video in FCPX. Are there any reasons to not use 60 frames in my video workfiles?
Cheers
Oli
Only if your intervals are short enough so that the time lapses will not play to fast. Personally I don't use 60fps. I mostly go for 30fps.

Ok, but in a 60fps workfile you can still use 30fps, just slow down the clip 50%. So in a 60fps workfile you have both options.
Or am I mistaking something?
When doing time lapse you always have a certain amount of frames. The fps is only a meta tag written into the file that tells the player how fast he should play. It does not matter if you export from LRTimelapse with 60 or 30 fps. Both files are the same size and have the same content. Only the fps meta tag differs. With "interpret footage" (see below) you can change this meta tag in a video editor.
The problems come in Video editing. By default the video editors will not stretch or slow down sequences because they think the timing is important (as for video with audio etc.). For timelapse this is different. Normally it's okay to strech it or slow it down a bit - you just don't want to lose frames.
If you accelerate/deaccelerate in a video editor, you will lose frames or frames will be interpolated.
Some video editors offer "Interpret footage" this allows you to change the framerate of clips without losing frames.
Bottomline: you should know about those things before you start working with different framerates. In the video editor, all clips should have the same framerates, otherwise you will get choppy results.
I work with FCPX and did a lot of slowmotion videos before. Mostly my workproject and exports had only 24 or 30 fps. But the clips I added for slowmotion used to have much more fps from my GoPro. The frames apear when I make this clips slower in my project workfile. This "feature" was the reason I switched to FCPX that time. But I think Adobe Premiere can also do it.
