How it works
From editable subtitles to a burned-in video export
This page is about the final render step. Keep captions editable while reviewing, then bake them into the MP4 when they are ready.
Prepare captions
Generate subtitles or import a subtitle file, then keep captions editable before rendering.
Check timing
Review caption timing against playback and fix timing before captions become permanent.
Choose the caption style
Pick a readable visual style that works when captions are rendered into the video.
Export MP4
Render the final captioned MP4 with subtitles burned directly into the video.
Before you render
Check the caption layer before it becomes part of the video
Burned-in subtitles are permanent in the exported file, so Captn keeps wording, timing and style editable before captions travel with the video.
Edit the words
Review text, casing, punctuation and line breaks before the subtitles are rendered.
Preview the timing
Check captions against playback and adjust subtitle blocks before the final render.
Lock the style
Use readable caption styling that matches the video, then export with previewed placement.
Export options
Export the final MP4 with subtitles baked in
The main output is a final captioned MP4. Subtitle files can still exist as supporting exports, but this page is about permanent captions in the video file.
Burned-in MP4
Export a video with subtitles permanently rendered into the final MP4.
SRT files
Keep a subtitle file as a backup or upload track when the platform supports captions.
Permanent social clips
Use the same hardcoded-caption approach for clips where viewers may watch without captions enabled.
Caption styling
Make burned-in subtitles readable before export
Tune the caption style before it becomes part of the video. Use clear outlines, backgrounds and highlights for Shorts, Reels, course videos and client-facing deliverables.
Preview first, then burn in.
Use cases
Burn subtitles into videos that need captions visible by default
Use burned-in captions when the video needs to be readable anywhere it is watched.
Short-form social
Hardcode captions for Shorts, Reels and feed videos so the text stays visible even when viewers never enable captions.
Product demos
Export explainers and walkthroughs with permanent captions that survive every player, embed and client review link.
Online courses
Publish lessons with captions baked into the video when a separate subtitle track is not reliable for learners.
Webinars
Turn long recordings into replay videos where readable burned-in captions stay visible on every platform.
Screen recordings
Add permanent captions to tutorials and demos so every step stays legible in the final rendered video.
Translated videos
Render translated subtitles directly into the localized video when viewers need the caption text visible by default.
Podcast clips
Burn captions into spoken clips so they remain understandable in silent autoplay feeds and reposts.
