When to transcribe the audio with Whisper. Subtitle transcripts cost $2 per 1,000 and speech-to-text transcripts $5 per 1,000 (first minute of audio included, then $0.0025 per started minute), at list price.
Fallback (default):the platform's own subtitles when a video has them (TikTok, YouTube), speech-to-text otherwise (always for Instagram and X).
Replace automatic captions: like Fallback, but videos whose captions are machine-made are transcribed with speech-to-text and billed at the speech-to-text price. In our test of 500 videos, automatic captions missed about 1 meaningful word in 120, and 5% or more of the words in 7% of videos; YouTube's also censor swearing. Captions written by the creator are kept. If speech-to-text fails, you get the captions at the subtitle price.
Always: speech-to-text for every video, at the speech-to-text price.
Never: subtitles only; videos without them are skipped for free.
