Use Closed Caption Editor in three steps
Start from media or an existing caption file
Use the upload path when you need a caption draft, or paste an existing SRT/VTT track when the caption file already exists.
Normalize the caption structure
Duetoday restructures the cue layout for readability and lets you keep editing the result before export.
Export the cleaned track
Copy the text, download the current format, or convert between SRT and VTT after the cleanup pass is done.
Who this workflow is for
Teams cleaning up rough auto-caption output before sending a video live.
Educators and creators who need an editable caption track instead of a fixed export only.
People moving between platforms that expect different caption formats.
What Duetoday does better here
One place for generation and cleanup
If you start from uploaded media, you can get the first caption draft and do the first editing pass in the same browser flow.
Keep the exported file format flexible
When the destination platform changes, you do not need to start again. Convert between SRT and VTT from the same cue set.
Reduce the usual copy-paste mess
The editor keeps the caption text structured so the conversion or cleanup step is faster and less error-prone.
Where this fits in real work
Cleaning lecture captions before posting recordings
Paste or generate the track, tighten the formatting, and export the version your learning platform accepts.
Fixing rough captions from a first transcription pass
Rewrap lines, clean the cue blocks, and keep the caption file easier to review before a final human pass.
Converting VTT to SRT for a client or internal workflow
Use one caption source, then switch the output format without opening another converter first.
Duetoday vs a format-only caption converter
A plain converter changes the file type. Duetoday also helps generate the initial cues and gives you an editable working area before export.
| Capability | Duetoday | Typical tool stack |
|---|---|---|
| Generate captions from uploaded media | Yes, you can create a caption draft before editing it. | Often expects you to already have a caption file. |
| Edit inside the browser | Paste, review, normalize, and export from the same page. | Frequently split across separate edit and convert tools. |
| Transcript reuse after cleanup | The transcript can stay available for Duetoday notes and follow-up workflows. | Most tools only care about the final caption file. |
| SRT/VTT switching | Convert the same cue set to the destination format you need. | May lock you into one export or a more manual copy-paste flow. |
Questions people ask before using it
Can I paste existing captions into this page?
Yes. The editor accepts existing SRT or VTT text so you can clean it up or convert it without needing a separate tool first.
Can I generate captions from media if I do not have a caption file yet?
Yes. Upload media, let Duetoday create the timed cues, and then keep editing the result from there.
Is this a full timeline editor?
No. This page is built for browser-first cleanup, normalization, and export, not for deep post-production timeline editing.
Will my manual edits stay in the export?
Yes. The output area is editable, so what you keep there is what gets copied or downloaded when you export the file.
Why would I use this instead of a subtitle desktop app?
If the main job is getting to a cleaner working caption file quickly, this is lighter and faster than opening a heavier editor for the first pass.
