Oops, didnt see that. Thank you! :)

You're quite welcome, Simon. Happy editing!

I'm in the same situation as OP, but I don't see any option to do this:

bwilhelm:

However, you can promote motion adapters to full timewarp effects in the Motion Effect Editor
and gain access to all of the parameters (ie: speed keyframes, etc.) of the timewarp that way.
Try that and please report back whether it works or not.

In the Motion Effect Editor, I see no option to promote. All settings are greyed-out.

Can you post a screenshot? It sounds like you may not be parked on the clip, or maybe the track is not enabled, but it's hard to say without seeing it.

Clip is a MOV with alpha... in a different frame rate and resolution from the project. Track is enabled, and I'm parked on the clip.  I'll send a screenshot if I can't figure it out soon.

I was able to apply Timewarp to the separate tracks after stepping in. Kind of clunky, but it worked. (I would have just edited my reply, but this forum makes all my posts disappear until they are approved, I guess.)

I'm glad you were able to figure it out.

Yes, because you are new to the forum, your posts have to be approved. I set your status to unmoderated, so that should'nt happen any longer.
