Which Video Editor Uses AI for Captioning?
Most video editors use AI for captioning. Learn what to compare, how VideoGen captions reach 98%+ accuracy, and how to style and export them.
VideoGen is a video editor that uses AI for captioning: it transcribes the voiceover or uploaded audio with 98%+ accuracy, applies animated caption styles you can customize, turns captions on across the whole project in one step, and exports them as burned-in text, SRT, or VTT. Most current video editors use AI for captioning in some form. The question that matters is how well each one does it: transcription accuracy on your audio, styling options, language handling, export formats, and whether captions can be applied across a whole project at once.
This guide explains what AI captioning does, gives you a checklist to compare editors, and shows how captions work in VideoGen.
How AI captioning works in a video editor
AI captioning starts with speech recognition. The editor listens to the audio track, turns the speech into words, and records when each word starts and ends. It then groups words into caption lines, places each line on the timeline at the moment it is spoken, and applies a visual style.
The quality of each step varies by editor. Speech recognition can stumble on names, product terms, and accents. Line grouping can split a sentence in an awkward place. Styling can be limited to a few presets or open to full control. Export can be burned into the video, saved as a separate file, or both.
That is why "which video editor uses AI for captioning" has a short answer (most of them) and a longer answer (compare them on the details below).
What to compare
Run this checklist on any editor you test. Use your own footage, not a demo clip.
- Accuracy on your audio. Count the corrections you need on a two-minute sample with real names and product terms.
- Styling control. Can you change font, color, position, and animation, or only pick a preset?
- Language handling. Does the editor caption the language you record in, and does it handle a mix of languages?
- Export formats. Burned-in captions, SRT, VTT, or all three.
- Project-wide captions. Can you enable captions for the whole project in one step, or do you caption each clip?
- Source audio. Does the editor caption a generated voiceover as well as recorded audio?
- Plan access. Check which plan includes AI captions. VideoGen lists this on the pricing page.
Write down the results side by side. The editor that wins on accuracy for your voice and vocabulary is usually the right choice, because every correction costs time on every video.
How VideoGen captions work
VideoGen generates captions from the audio already in your project. That can be a text-to-speech voiceover created from your script or an audio file you upload. Transcription accuracy is 98%+.
Captions are a project-wide setting. The "Enable captions" remix action turns them on for the whole project in one request, and the captions land in the AI video editor timeline next to the rest of your edits. If the recording has filler words or long pauses, run "Clean up transcript" first. It handles roughly three hours of speech in one pass and judges words in chunks of about 300 words, in parallel, with a language model that reads each word in context. Captions generated afterward match the cleaned audio.
Styling is open. Pick an animated caption style, then set the font, color, position, and animation to match your brand. The auto subtitle generator page shows the styles in use, and the AI caption generator page covers the generation options.
Export offers three outputs: captions burned into the video, an SRT file, or a VTT file. You can use the burned-in version for social feeds and keep the SRT or VTT for players that support caption tracks.

Caption styling that reads well on phones
Most captioned video is watched on a phone with the sound off. Style for that case first.
- Use a large font. If the text is hard to read at arm's length on a phone, it is too small.
- Keep contrast high. Light text on a dark background box, or dark text on a light box, reads in any scene.
- Place captions in the safe area. Keep them away from the bottom edge, where platform buttons and progress bars sit, and away from the top, where titles and account names appear.
- Keep lines short. One thought per caption line is easier to read than a full sentence.
- Pick one animation and keep it. A single animated style across the video looks deliberate. Mixed styles look like a mistake.
- Check the vertical version. VideoGen switches the whole project between 16:9, 9:16, and 1:1 in one request, so review caption position after each switch before you export.
Export options and accessibility
Each export format serves a different audience.
| Format | Where it shows | Best for |
|---|---|---|
| Burned-in | Always visible, part of the video image | Social feeds and autoplay with sound off |
| SRT | Separate file, toggled by the viewer | Video platforms and players with caption tracks |
| VTT | Separate file, toggled by the viewer | Web players and HTML video |
Burned-in captions reach everyone who sees the video, including viewers who never turn captions on. Separate files let viewers choose, let players resize the text, and let assistive tools read the text. Exporting both covers the widest audience: post the burned-in version where sound is often off, and attach the SRT or VTT file where the platform accepts caption tracks.
Frequently asked questions
Do all video editors use AI for captioning?
Most current editors include some form of AI captioning. They differ on accuracy, styling, language handling, export formats, and whether captions apply to a whole project at once, so compare them on your own footage.
Which video editor uses AI for captioning on a text-to-speech voiceover, not only recorded audio?
VideoGen captions both. It transcribes the text-to-speech voiceover generated from your script or an audio file you upload, at 98%+ accuracy, and places the caption lines on the project timeline.
Can I export AI captions as an SRT or VTT file instead of burning them into the video?
Yes. VideoGen exports captions as an SRT file, a VTT file, or burned into the video image. Use the separate file where the platform accepts caption tracks and the burned-in version for feeds with sound off.
Do I need to caption each clip separately, or can one step caption a whole project?
In VideoGen, one step does it. The "Enable captions" remix action applies captions across every clip in the project in one request, and the captions stay editable on the timeline afterward.
