Slowing a clip down is how you show what actually happened; speeding it up is how you make twenty minutes of something watchable. Both are a speed multiplier applied during the encode, which is why they live here and not in an editor.
Convert offers six steps — 0.25×, 0.5×, 1×, 1.5×, 2× and 4× — and names what you're doing as you pick: slow motion below normal speed, timelapse above it. The change is baked into the output file, so whatever plays it afterwards just sees an ordinary clip at a new length.
00:04:18:12How it runs
Six steps, 0.25× to 4×
0.25×, 0.5×, 1×, 1.5×, 2× and 4× — the useful multiples rather than a slider you have to nudge onto a round number.
Baked into the file
The output is an ordinary video at its new duration — no player-specific speed metadata to be ignored.
Stacks with the rest
Combine with trim, crop and a resolution change in the same pass; the estimate updates as you go.
