overcaption / batch subtitle generator
Subtitle a whole folder of videos. One run, offline.
Drop in as many files as you have, set up the pipeline once, and collect finished subtitles, translations and burned-in videos for every one of them. All of it on your own computer: nothing is uploaded, and nothing is billed per minute. Part of Overcaption Pro, free to try for 14 days; the app around it is free forever.
Why batch on your own machine
- No per-minute pricing. Cloud batch tools meter every file because their servers do the work. Here the work happens on your hardware, so a backlog of forty interviews costs the same as one: nothing beyond the Pro license you already have.
- The whole pipeline, not just transcripts. One run takes each file through transcription, translation into the languages you picked, SRT, VTT or plain-text export, and, if you want it, a styled burned-in video. Not a pile of raw transcripts to finish by hand.
- Built for the backlog. Queue it before you leave; files process one after another, without soaking up the whole machine, and everything lands named and sorted in the folder you chose. A report notes what happened to each file.
- Every file stays editable. Each video becomes a real Overcaption project. Spot a wrong name in episode three? Open it in the editor, fix it, re-export that one file.
How it works
-
01
Drop in the files
Video or audio, mixed freely. Drag them onto the app, or drop a whole folder's worth at once.
-
02
Set the pipeline once
Transcription model and language, the languages to translate into, the formats to export, whether to burn the captions in and in which style. It applies to every file.
-
03
Let it run
One screen shows every file's progress. Pause, resume or cancel any time; a file that fails doesn't stop the others, and you can retry just that one.
-
04
Collect everything
Finished files land in your output folder as they complete, named consistently. Save it all as one zip if you prefer, subtitles only or videos included.
What one run can produce
The pipeline multiplies, so a modest setup goes a long way: eight episodes, translated into Italian and French, exported as SRT with burned-in originals, comes out as eight transcriptions, sixteen translation tracks, twenty-four subtitle files and eight captioned videos. Configured once, reviewed over coffee.
Translations run on local models, in any of the 50+ supported languages, with grammar-aware line breaks per language. The languages page has the per-language breakdown.
What is free and what is Pro
The single-file workflow, transcription, the editor, local translation, every export format and burn-in up to 1080p, is free with no time limit. Batch processing is part of Overcaption Pro at $99 a year or $19 a month, alongside the rest of the finishing suite. The 14-day free trial includes batch, up to five files per run, so you can try the real thing on your own footage. Details on the pricing page.
FAQ
How many files can a batch hold?
As many as you drop in; there is no fixed ceiling. Files process one after another, so a big batch simply takes longer, and an overnight run is the natural fit. During the free trial, batches run up to five files each.
Do the files get uploaded anywhere?
No. Transcription, translation and burn-in all run on your machine, same as the rest of the app. Two optional cloud engines exist for transcription and translation, clearly labeled, and even those never upload your video file.
What happens if one file fails?
The rest keep going. The failed file is marked with the reason, you can retry it on its own, and the batch report in your output folder records what happened to every file.
Can I fix the subtitles afterwards?
Yes. Every file in a batch becomes a full project: open it in the editor, correct the text, retime lines, restyle, and export again, without re-running anything else.
