Quick question regarding FCP Slow Motion?

I'm editing a project and there is a part where I film someone doing a flip, and the peak of the flip I would like to use some slow mo. Now here's the problem, since I have music edited to this ( Music Video ) when I create the slow mo everything in the timeline jumps forward.


So my question is this, Is there a way to create slow mo and still preserve the time and place of a clip?


Thank You
 
Not without speeding up another part of your footage. By slowing down a clip, you're essentially adding time to your sequence. So that time has to go somewhere. It sounds like what you want is time remapping/speed ramping.

Exactly! That's what I need "time ramping" Any ideas or places I can get some more info on this?

Thank you
 
I know Videocopilot has a tutorial based in After Effects, but the principles are the same in any software. So that might help.

As CB said, you can do this in FCP using the controls in the motion tab. But if you have access to After Effects I would do it there instead. You have better/easier control and will get better results with the frame blending. Or if you don't have After Effects, try Motion maybe. I would imagine it's similar.
 
Yep what you want is Time Remapping. After Effects has this feature and I'm sure Apple Motion would as well. Time remapping allows you to stretch and remap the contents of a clip, without changing the length or the in/out points - very useful when you want to add speed effects without changing the length of your edit or putting material out of sync.

If you had to do it in Final Cut, getting the timing perfect might be easier if you split your clip into sections and apply speed changes individually rather than applying one speed ramp to the whole clip. The problem with a speed ramp is you will be endlessly adjusting to try and get your sync exactly back to where you need it. So, use the blade tool to cut out the section of the clip you want to remap - you might want to copy it to a new track just so you know you have an untouched version you can revert to if needed. Then split this clip into three sections, the middle one marking the section you want to be in slow motion. Speed up the beginning and end sections, then slow down the middle section as much as you need to to make it fill the gaps. It won't be as smooth or flexible as time remapping but it kind of works in the same way.

Of course the other easy option is to slow the section down, the cut back to an angle/take which is in sync. Then you can just drag the first clip back into sync before you cut back to it.
