Frequently asked
Straight answers about SubVela.
The essentials for creators evaluating a private, local subtitle workflow.
Does SubVela upload my videos?
No. Whisper transcription runs on your Windows machine, so your media does not need to be uploaded and no transcription API key is required.
What can SubVela export?
Export subtitles as SRT or styled ASS files, or burn subtitles directly into the video with FFmpeg.
Can it create bilingual subtitles?
Yes. SubVela can show original and translated lines together, style them independently, and handle Chinese, Japanese, and Korean fonts.

Yes. The core application is MIT licensed and free to use. The Windows installer bundles components such as FFmpeg under their own licenses; the licensing panel lists those terms.
