How to Slow Down a Video for TikTok

The fastest way to slow down a video for TikTok is to use the speed control in the app's editing tools, but whether it looks good was decided when you filmed it. Here's how to do it, and how to predict the stutter before you commit.

Slow down a video for TikTok with the built-in speed control

TikTok's editing tools include adjusting video speed. Speeding or slowing the pace of video clips. It's a per-clip control, so one shot can run slow while the rest of the edit stays at normal pace.

That's the easy half.

Why slowed footage stutters, in numbers

TikTok's own developer documentation states the frame rate it accepts: a minimum of 23 FPS and a maximum of 60 FPS. That range is the whole explanation.

Slowing a clip doesn't invent new frames. It spreads the frames you recorded across a longer stretch of time, holding each one on screen for longer. Film at the top of that accepted range and there are frames to spare. Halve the speed and the motion still reads as continuous. Film near the bottom and there's nothing in reserve, so each frame lingers visibly and the movement breaks into steps.

The practical version: slow motion is a shooting decision that the editor can only execute, never rescue.

Captions that stay on the right word

Montaj doesn't change playback speed. What it does bring to a clip where the pacing has been deliberately shaped is word-by-word subtitle timing. Each word carries its own timing rather than sitting in a block of text that appears and disappears with the line. Correct a word inline and the timing follows it. On footage that's already been slowed for effect, captions that land on the right syllable are what stop the text and the picture drifting apart. Learning how to slow down a video for TikTok is one decision; keeping the words attached to it is the next.
