I just ran into that, where I wanted to speed up for a exported gif or mp4 that shows a drag behaviour that was set at 300%.
But setting up for video export there is no way to replicate that speed.
Would be good if we had an option for setting not only speed for exports but also speed of timeline play similar to what we have in the control timeline action.
This is great, but for fine tuned results I’d recommend using time remap selection/feature found in After Effects. One great thing about it is, like I was saying in my earlier posts AE gives the flexibility of key-framing on a granular level and ramping up speed in between key-framed points by dragging in and ends and it doesn’t stop there, you can keyframe more points to get the result your looking for. After all set and done, I use adobe media encoder for whatever export is needed avi, mp4…
