How to Add Captions to TikTok Videos

Choose based on where the video will run and how much control you need over the look.

TikTok introduced auto captions as an option on the editing page after you upload or record a video. The exact button placement changes between app versions, but the flow stays the same:

Burn captions in when the same clip goes to more than one platform. A clip cut from a long YouTube video or podcast is usually posted to TikTok and YouTube Shorts. Captions you design once travel with the file, and you don't have to fix the same transcription errors in two apps.

Burned-in captions also carry editorial choices that native captions can't: highlighting the key word, keeping two lines short enough to read in a glance, or moving the text up when a product is shown at the bottom of the frame. On a talking-head clip, fewer words per line and a steady position are usually easier to follow than fast word-by-word animation. Test both on your own audience before choosing a house style.

The downside is permanence. A misspelt guest name is now part of the video. Review the captions at full size on a phone before exporting, not just in the editor's timeline view.

An SRT file is the simplest caption format: a line number, a start and end timestamp, and the text shown during that time. Because it is plain text, it is easy to correct, translate or search, and many platforms accept it as a separate caption track.

On YouTube, you can upload a subtitle file with timing to a video. LinkedIn lets you attach an SRT file when posting a video from a desktop computer. For TikTok, the practical route is to keep the SRT as your corrected master copy and export the video with those captions burned in. That way the corrected text is the version viewers see on every platform.

In HypeNest, the caption workspace lets you download the SRT for the transcript and export the video with styled captions. Correct the transcript once, then use the burned-in export for TikTok and Shorts and the SRT where a platform accepts caption files.

A cooking podcast cuts a 58-second clip where the guest explains why resting meat matters. The clip goes to TikTok and YouTube Shorts. Auto captions in the TikTok app transcribe the guest's name, "Aoife", as "Eva" and "Maillard" as "my yard". Both are easy to fix, but they would have to be fixed again in YouTube's editor.

Instead, the editor corrects the transcript once, sets captions to two short lines in the upper-middle of the frame so they don't cover the cutting board, highlights "rest" and "ten minutes", and exports with burned-in captions. The same MP4 goes to both platforms. Auto captions stay off on TikTok so two caption layers don't overlap. The corrected SRT is kept for the full YouTube episode.

• Names, brands, numbers and technical terms match what was actually said.
• Only one caption layer is visible: don't add TikTok auto captions on top of burned-in ones.
• Text avoids the face, the product and the areas where the app places buttons and the post description.
• Lines are short enough to read at normal playback speed on a phone, with sound off.
• Timing matches speech after your final trim. Re-generate captions if you cut the clip again.
• Emphasis is used on a few words, not every word, so it still means something.
• For accessibility, captions include important non-speech sounds when they matter to the meaning.

If you are cutting clips from a longer video, captions are one step in a bigger job. The subtitles feature adds burned-in captions to clips as they are drafted, so every candidate is readable on mute when you review it. For a finished video that only needs captions, use the video caption generator: upload the video in HypeNest, choose a style and position, correct the text and export.

When a clip is approved, HypeNest can publish it directly to TikTok or YouTube, or you can export the file and post it yourself. Either way, check the uploaded version on a phone once more. The app interface covers part of the screen differently from an editor preview.
