Transparent Captions
Captions with a Transparent Background
Export your captions on their own as a clip with a real transparent background, an alpha MOV or WebM. Drop the overlay onto any timeline in any editor and the captions sit cleanly over your footage, with no green screen to key out.
How It Works
A Caption Overlay in Three Steps
Generate captions, style them once, and export them as a transparent overlay you can layer over any footage.
Upload Your Video
Drop in an MP4, MOV, MKV, or WebM file. The spoken language is detected automatically, or you can set it yourself.
Generate and Style
The speech is transcribed with word-level timing. Choose caption or karaoke highlighting, set the font and size, and translate the captions if you need to.
Export the Overlay
Render an alpha MOV or WebM with just the captions on a transparent background, ready to drop onto your timeline.
Capabilities
A Caption Overlay That Drops onto Any Timeline
A genuine transparent caption clip, styled exactly the way you want, that layers over footage in any editor.
Real Alpha Channel
A true transparent background in MOV or WebM, not a green screen you have to key out, so there is no spill or fringing to clean up.
Styled Once, Baked In
Caption or karaoke highlighting, background boxes, fonts, and size are all rendered into the overlay, so it looks right the moment you drop it in.
Editor-Agnostic
Layer the overlay over your footage in Premiere Pro, DaVinci Resolve, Final Cut, or any editor that reads an alpha channel.
Word-Level Timing
The captions carry word-level timing, so they stay in sync with the speech once the overlay is aligned to the footage.
Translate the Overlay
Export a separate overlay for each of 21 languages, so one master edit ships in several languages.
Other Exports Too
Also export SRT, VTT, an After Effects project, or a burned-in video from the same project.
Alpha vs Green Screen
Why an Alpha Overlay Beats Green Screen
Both let you layer captions over footage, but a real alpha channel skips the keying and the cleanup that green-screen captions force on you.
| Transparent (alpha) overlay | Green-screen captions | |
|---|---|---|
| Background | Truly transparent (alpha channel) | Solid green you have to remove |
| Keying needed | None, drop it straight in | Yes, chroma-key every clip |
| Edge quality | Clean, no spill | Risk of green fringing on the text |
| Formats | MOV or WebM with alpha | Any video with a green fill |

FAQ
Common Questions
Transparent subtitles are captions exported as a video clip with a transparent background, so only the text is visible. You layer the clip over your footage in an editor and the captions appear on top, with everything around them see-through.
A transparent overlay uses a real alpha channel, so there is nothing to key out and no color spill or fringing. Green screen captions need you to key the background, which can leave edges around the text. Alpha MOV and WebM overlays drop in clean.
MOV and WebM can carry an alpha channel, so both are exported with a genuine transparent background. Most editors read one or both of these formats with transparency intact.
Import the MOV or WebM and place it on a track above your footage. The captions show over the video and the rest of the overlay stays transparent, so no keying or masking is needed.
Any editor that reads an alpha channel, including Premiere Pro, DaVinci Resolve, and Final Cut Pro. You place the overlay on a higher track and the transparency is preserved.
