BUMP!
I need this
This would be extremely useful for me and I know a few others who could use it too, if someone could make a plugin or something for this I would be extremely grateful.
Having just a scene (or even better a source) that turns the velocity of a source down to 0% would be amazing. Even then if you wanted to do more you could make it so you could change the entire velocity of the source you're mirroring so that people could do something like a slow motion effect. All that being said, all I personally really need a freeze frame.
