Time Warping #962

Closed ghost closed 4 years ago

Is your feature request related to a problem? Please describe.

Not related to a problem. Folks in the Olive Subreddit, Discord, and (unofficial) Facebook group discussed about time-warping.

Describe the solution you'd like

Keyframeable clip speed. I believe Blender's sequencer is the only NLE out there with time-warping with its source code available.

This feature could solve https://github.com/olive-editor/olive/issues/902 too if one keyframes the speed to 0?

Describe alternatives you've considered

The current method for "keyframing speed" is to have multiple, split fragments of a clip with different speeds. Not a productive and performant solution.

Additional Notes I opened this issue because Olive users from different platforms discussed about this feature.

It would definitively make Olive the coolest NLE EVER !

I wonder if librubberband could be hijacked here. It's audio specific, but allows keyframe type stretching in non-linear fashion. I'm not sure how one would go about applying this to 2D graphics though...
