Change a segment’s speed

Speed up the long climb in a thermal, or slow down the landing. Each segment has its own speed.

The Segment speed sheet with 0.25× to 16× buttons, 4× selected, and the segment's length in the output.

Set the speed

Select the segment (tap it on the timeline). Split first if only part of it should change.
Tap Speed.
Pick a speed: 0.25×, 0.5×, 1×, 2×, 4×, 8×, 16×.
Tap Done.

The sheet shows where the segment is in the original video and, in orange, how long it will be in the finished video. The segment’s label on the timeline changes to the new speed, and the preview shows it in its corner.

Sound

Up to 4×, the sound plays at the new speed but keeps its natural pitch (no chipmunk voices).
At 8× and 16× the sound is muted, because it would be noise.

Back to normal

Select the segment, tap Speed, choose 1×.
