Here is a sneak preview of one of the things planned for version 21.04 (April)

Time Remapping!

To use it you must choose a clip with NO B-frames (that is a video encoding terminology). If you try to use it on a such clip you will be blocked by a dialog asking you to use Properties > Convert on it.

After that, it is basically Filters > Time > Time Remap > Keyframes. Go to this forum post for more information.
