How to Split a Video for TikTok
The fastest way to split a video for TikTok is to use the split control in the app's own editor, then delete or reorder the segments you've created. Here's the workflow, plus the difference between splitting inside one post and splitting across several.
Split a video for TikTok in the built-in editor
TikTok's editing tools let you stack, trim and split video clips. Splitting is what turns one long recording into pieces you can treat separately. Drop the segment that sags, move a strong moment forward, keep the rest.
Splitting into separate posts is a different job. That happens to the file before it reaches the app, and it's driven by length rather than pacing.
How long a single post can actually be
TikTok's Content Posting API documentation is the clearest published statement on this: videos of up to 10 minutes can be sent through its upload endpoint, and it explicitly notes that the actual maximum post duration varies by creator account. That caveat is the important half. There isn't one universal ceiling to plan against, which means "will this fit in one post?" is a question about your account, not about TikTok in general.
Practically: if you're near any limit, split by content rather than by the clock. A part that ends mid-thought reads as a technical failure, not a cliffhanger.
Splitting, reordering, undoing
Montaj keeps a real timeline, so splitting a take and reordering the pieces is a normal editing move rather than a destructive one. The segments stay draggable, and 100 steps of undo sit behind every decision. It all runs on your device, with nothing uploaded. Once you know how to split a video for TikTok, being able to try three different running orders is what turns the split into an edit.

Decide which kind of split you mean
Splitting inside one post breaks a take into segments you can trim and reorder. Splitting across posts turns one recording into a Part 1 and a Part 2.

Re-time your text after every split
TikTok lets you edit, position and set the duration for text. A split changes which segment a line belongs to, so overlay durations need checking afterwards.
