Reverse a video clip (play it backwards)

PandaStudio plays any part of a video backwards: add a speed change over the span and switch on Play backwards, and that span rewinds in the same time it takes to play forwards.

Reverse is a setting on a speed change. Add one from Add on the timeline toolbar (Speed up or slow down), drag it over the part you want to rewind, and switch on Play backwards in the Speed change panel. The span plays backwards in its own slot on the timeline at the speed you pick, so 1× rewinds at normal speed and 2× is a fast rewind. The recording's sound is silent there by default; under More options, Sound when reversed switches between Silent and Reversed (the audio plays backwards too). Reversed playback is constant speed, so Ease in and out is off while Play backwards is on. A reversed span must be at least 100 ms long and can't overlap another speed change, ramp or freeze frame. It reverses the main video on the timeline, not a single overlay. The preview and the export play the same frames.
