How to Add Text to a Video for TikTok

The fastest way to add text to a video for TikTok is to type it in the app's editor, set a duration so it appears and leaves at the right moment, and keep it clear of the interface. Here's the full pass, plus the two things TikTok publishes that decide where the words can go.

Add text to a video for TikTok with the built-in editor

TikTok's editing tools let you edit, position and set the duration for text. That last part is the one people skip. A line with no duration sits on screen for the entire clip, which is how a video ends up with four titles stacked on top of each other by the halfway point.

Give every line an in and an out. It's the difference between text that reads like part of the edit and text that reads like a sticker.

Where the app's own interface takes over the frame

The frame you edit in is not the frame the viewer sees. TikTok's creative guidance for creators is direct about it: save space on screen for the TikTok UI.

Two published details make that concrete. First, safe zone size varies with your caption length. TikTok states that the longer the caption, the smaller the safe zone becomes. So the caption you write at posting time retroactively decides how much room the text you placed earlier actually has. Second, TikTok advises against transparent or white backgrounds, because nicknames, captions, music captions and UI icons in the app are white and vanish against them.

The practical version: keep text in the central band of the frame, away from the bottom third and the right-hand column, and don't rely on the corners existing.

And keep lines short. TikTok's guidance suggests 5-10 words per second when using text. A line that takes three seconds to read needs three seconds on screen.

Moving text on a real timeline

Montaj puts animated text on a real timeline, so each line has a position in time as well as in the frame, and it moves rather than sitting still. Because it's a timeline rather than a duration field, adjusting when a line lands is a drag, and 100 steps of undo sit behind every attempt. Everything renders on your device, with nothing uploaded. Once you're adding text to a video for TikTok in any quantity, that's the difference between placing text and actually timing it.
