Japanese audio → English .srt
English subtitles for any Japanese video.
Drop a video on SubsRip and get a timed English subtitle file beside it. It runs on your computer with your own transcription and translation accounts, so there is no subscription and no middleman.

Watch it work
From a line of Japanese to a line you can read
Each video shows where it is: extracting audio, transcribing, translating, saved. The timing of every line comes from the speech and is never changed by translation.
How it works
Three steps, one window
Add your keys once
Paste a key for a transcription service and a translation service. They stay on your computer, in its keychain.
Drop a video or watch a folder
Drag files onto the window, or point SubsRip at a folder and let it pick up new videos by itself.
Get the .srt next to the video
A timed English .srt appears beside the video, named to match, ready for any player.
Before you start
Get an ElevenLabs key for the transcript
The transcript decides how good the subtitles are. Of everything we tried on Japanese speech, ElevenLabs Scribe was the most accurate, so SubsRip uses it by default. Create an account, copy an API key, and paste it into SubsRip.
- Create an ElevenLabs account and open its API keys page.
- Create a key and copy it.
- In SubsRip, choose Add key and paste it.
- Add a translation key the same way. xAI is the default; Gemini, OpenAI, DeepSeek and others work too.
Where your video goes
Your accounts. Your files. No server of ours.
SubsRip has no backend. It talks to the services you choose, directly, and nothing passes through subs.rip.
- On your computer
Audio is extracted locally
ffmpeg is built into the app. The video file itself never leaves your computer.
- Your transcription service
Speech becomes timed text
The audio goes straight to the transcription service you picked, on your account.
- Your translation service
Lines are translated
The transcript text goes to the translation service you picked. Timings are never touched.
- On your computer
The .srt is saved
The finished subtitle file is written next to the video.
Services
Pick who transcribes and who translates
Change either one in Settings at any time. If a translator rejects your account or runs out of credit, SubsRip can switch to a second one and carry on.

Long videos
A failure costs you one step, not the job
Every finished step is saved as it completes. If the network drops or a service says no two hours in, press Try Again and SubsRip continues from the last saved step.

Questions
Straight answers
What does it cost?
The app is free. You pay the transcription and translation services directly, at their prices, through your own accounts.
Which keys do I need?
One for transcription and one for translation. ElevenLabs and xAI are the defaults, and ElevenLabs gave the best Japanese transcripts of everything we tried. An xAI or Gemini key can do both jobs.
Does my video leave my computer?
The video file stays on your computer. Its audio is sent to the transcription service you choose and the transcript to the translation service you choose. Nothing is sent to subs.rip.
Does it only do Japanese to English?
SubsRip was built and tested for Japanese speech and English subtitles. You can set another spoken language or target language in Settings, but those pairs have had less testing.
Does it run on Windows and Linux?
Yes. SubsRip runs on Mac (Apple silicon, macOS 14 or newer), Windows 10 and 11, and 64-bit Linux as an AppImage or a .deb. Every version uses the same engine and the same services.
What happens if a long video fails halfway?
It keeps every finished step. Try again and it continues from where it stopped, without paying for the same audio twice.
Is this as good as a human subtitler?
No. It is a readable first pass. Expect to fix wordplay, names, overlapping speakers and the occasional misheard line.
