slow down with Time Remap – I am STUMPED!

[Mary beth Koplin]

ok, Arnie, thank you . In my reading I saw that Time Remap requires that the slower part of the clip will require the rest of the clip to be faster, so the duration stays the same. Is this what you are referring to?

[Arnie Schlissel]

If I understand you, you want the beginning and the end of the clip to be normal speed, while the rest of it is slower than normal.

At the same time, you want it to be exactly the same length, even though most of the clip is slower than normal.

Well, as Mr. Spock would tell us, this is not possible without violating the laws of physics.

In order to do what you want to do, some part of the clip must be faster than normal speed to take up the difference in length.

If you don’t mind the clip being longer, or your out point being earlier, then what you want is fairly easy.

Yup, that’s it exactly.

As far as I know, you can’t really do this in FCP – not smoothly anyway. It’s pretty easy in After Effects. Simply enable time remapping for the layer, then create some keyframes at several points within the clip. You can then move the keyframes causing the speed to change. As long as there’s a keyframe at the end of the clip that’s not moved, the run time does not change. Also, applying “easy ease” to the keyframes with smooth out the transitions. Hope this makes sense!

Butting in.
After years of time remapping in After Effects, I can tell you that it doesn’t matter how many keyframes you use but you must have two keyframes at the end of your clip. Say they’re positioned at the last frame and about 15 frames before the last frame.
The one at 15 frames tells FCP to make a speed change from this point to the end. The last one tells FCP the clip has ended, no more frames are available. What’s going on is the one 15 frames forces all the rest of the frames that haven’t been used yet to play in the last 15 frames.

The next-to-the-last KF can be anywhere. It’s only function is to use up all the rest of the frames that haven’t been shown yet. This is best accomplished with about 5 seconds of padding at the ned of the clip so the next-to-last KF can be used to smoothly come to a halt or to smoothly ramp back to normal speed.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”
