Resolume Forum

Most parameters can be run with an envelope. Why not video clip speed, or am I missing something?

Clip speed is not a regular parameter, it doesn't have animations at this time.
Here is the feature request about it, feel free to join the discussion viewtopic.php?t=20975

You can hack this using Wire by creating a Float In for the Video Players Phase, but you would need to do this for each clip and that can take some time. If it's just for a few clips, this might be a solution for now.

Agreed I'd LOVE this feature. I find myself wishing it on nearly every show I'm on.

Lots of quick trips to/from After Effects when sometimes it'll be just fine in Resolume even with seeing the frames stuttering as it ramps.
