Caption Burn-In
Caption burn-in is the process of permanently encoding captions directly into the video file, as opposed to adding them as a separate, selectable subtitle track.
When captions are burned in, they become part of the video image itself. Every viewer sees them automatically, regardless of the platform, device, or playback settings. There is no option to turn them off. This is different from soft captions (separate SRT or VTT tracks) which viewers can enable or disable and which some platforms strip during upload.
For short-form video on TikTok, Instagram Reels, and YouTube Shorts, burned-in captions are standard practice. These platforms are primarily used on mobile with sound off — over 80% of short-form video is watched without audio. Captions that depend on the platform’s subtitle system may not display consistently across all devices, browsers, and embed contexts. Burned-in captions always display.
The trade-off with burn-in is permanence. You cannot edit burned-in captions after export without re-rendering the video. If there’s a transcription error in a burned-in caption, the fix requires running the clip through the pipeline again. This is why transcription accuracy matters so much before the burn-in step.
AutoClip burns captions directly into the video file using word-level timestamps from Deepgram’s transcription. The result is precisely synchronized, styled captions that display identically on every platform with no compatibility issues.

Frequently Asked Questions
What is the difference between burned-in captions and subtitles?
Burned-in captions are part of the video image and always visible. Subtitle tracks are separate files or streams that viewers can toggle on or off. Burned-in captions are standard for short-form social video because they display reliably on all devices and platforms.
Why do clippers burn captions into videos instead of using subtitle files?
Short-form platforms handle subtitle files inconsistently. Burned-in captions guarantee the same display across TikTok, Reels, Shorts, and any embed context. They also look native to the platform aesthetic, matching the styled caption format that audiences expect on short-form content.
Does AutoClip burn captions into clips?
Yes. AutoClip burns animated captions directly into every exported clip using Deepgram word-level timestamps. The captions are permanently part of the video file and display identically on every platform.
