Buttons

• [Add Velocity] Adds velocity.
• • Regular: default time-remapping.
• • Advanced: time-remapping with a speed slider.
    
• [Split] Splits the layer and removes useless velocity keyframes.
• [=] Opens the 'minimal speed' calculator.
• [?] Shows some information.

Controllers

Speed (%): playback speed.
Offset: frame offset (the value shows the real frame offset only with 1000fps footage, with other framerates it shows 1000/<layer_fps> times higher value).
Time-reverse layer: reverse playback, play the source from end to start.
Graph support (SLOW!): audio only controller, <0> force linear keyframe interpolation, <1> graph support (make sure to set comp fps to 30+, otherwise your audio will stutter a lot)
