Questions, answered
MP4 transcript questions
Can I upload a three-hour MP4?
The uploader checks the configured size and duration limits before processing. Large files use a queued private media workflow.
Does the page fetch videos from a URL?
No. Upload a video file you own or have permission to process. CastTranscript does not provide a video downloader.
Can I export subtitles from an MP4 transcript?
Yes when verified sentence timing is available. The same project can export SRT or WebVTT alongside TXT and Markdown.
