Long recordings in parts
Each upload is limited to 10 minutes, so split a webinar recording into sections and caption each one. Processing uses minutes from your free allowance or one-time pack, so check your balance first.

FAQ
Webinar subtitle generator FAQs
How long of a webinar can CapsAI handle?
Each upload is limited to 10 minutes of video. Split a longer recording into parts, caption each part, and join the exports in your video editor. Processing uses minutes from your free allowance or one-time pack, so check your remaining minutes first.
Does it handle multiple speakers in a webinar?
CapsAI transcribes the speech in the recording. Review the draft carefully where speakers overlap or interrupt each other, and edit the text if you need to identify who is speaking.
Can it handle technical/industry jargon?
Jargon, acronyms, and product names can be transcribed incorrectly in the first draft. Review and correct them in the editor before export.
What webinar platforms are supported?
CapsAI works with recordings, not live platforms. Save your webinar recording as an MP4 or MOV file and upload it to CapsAI.
Can I subtitle just a portion of a webinar?
Trim the recording to the section you need before uploading, then generate captions for that clip.
Which files can I upload?
The uploader accepts MP4 or MOV video files. Audio-only files and pasted video URLs are not part of the caption workflow.
Can I download SRT or VTT subtitle files?
The export is an MP4 with the captions burned in. Separate SRT or VTT files are not available from the editor yet; the standalone converters under /tools work on subtitle files you already have.
How accurate are the captions?
Accuracy depends on audio clarity, background noise, accents, and language selection. CapsAI creates a first draft and lets you edit captions before export.
How much can I try for free?
You can start with 3 free minutes. Free video export may include a CapsAI watermark; watermark-free video export is listed as a paid-plan benefit.
