How to Trim a Video for TikTok
The fastest way to trim a video for TikTok is to open the clip in TikTok's editor, drag the handles until the hook is the first thing on screen, then check the new opening with the sound on. Here's the full pass, and why the head of the clip deserves more attention than the tail.
Trim a video for TikTok in the app's own editor
TikTok's editing tools let you stack, trim and split video clips in the creation flow, so a first cut doesn't need a separate app. Drag the handles in, preview, adjust. It's quick, and for a clip that's already close it's all you need.
The limit is that trimming only works at the edges of what you already recorded. It won't tighten anything inside the take.
The opening seconds are what you're really trimming for
TikTok's creative guidance for advertisers is blunt about where attention lives: prioritise the hook in the first six seconds, and it reports that 90% of ad recall impact is captured within those first six seconds. That reframes the job. You aren't shortening a video, you're deciding which frame gets to be the first one. Faster scene changes early on, in TikTok's words, "typically draw viewers in early", so the walk to the camera, the throat-clear and the "okay, so" all belong on the wrong side of the cut.
Trimming on a timeline you can keep working on
Montaj keeps a real timeline, so a trim is a move you can revisit rather than a one-way render. Cut, reorder the pieces, come back and pull the handle out again. The clip stays editable while you're still deciding what the opening should be. Everything happens on your device, and nothing is uploaded to make it work. Once the length is settled, knowing how to trim a video for TikTok matters a lot less than what you do with the twenty seconds that survived.

Play it back with the sound on
A trim that looks clean can cut a word in half. Listen to the new first second before you post.
