Good to know.
How accurate is it?
Clear speech transcribes very accurately. People's names and brand names can be misheard; edit the SRT if you need them exact.
Can I upload just audio?
Through the API, yes: MP3, M4A, WAV and FLAC work for caption files. The studio takes video files (MP4, MOV, WebM or MKV).
How is it priced?
By the length of your clip. A caption file is the cheapest output; translation and burning in cost more.
How long can a clip be?
In the studio, up to 10 minutes and 2 GB per run. The whole clip is processed, so trim longer videos first.
