Frequently Asked Questions

What video formats does Clario support?

Clario Premium supports MP4, AVI, MOV/QuickTime, MKV, WMV, WebM, and 3GP video files. Download your lecture video from your course platform (Canvas, Blackboard, Zoom, etc.) and upload the file directly. Clario processes the audio track for transcription and study material generation.

How do I download a YouTube or course platform lecture?

For course platform videos (Canvas, Blackboard, Panopto, Zoom recordings), check your institution's download policy — many platforms allow students to download their own course recordings. For YouTube lectures posted by professors, standard browser tools or download utilities may be used where permitted. Upload the downloaded video file to Clario for processing.

How accurate is video lecture transcription?

Clario uses Deepgram Nova-3 English for transcription, which achieves high accuracy for clearly recorded educational content. Quality is best with recordings that have a clear single speaker, minimal background noise, and standard academic English. Most lecture recordings from university platforms transcribe with very high accuracy.
