Summarize MP4 recordings

By the Potok teamUpdated ~2 min read

Summarize MP4 recordings by sending the file to Potok in Telegram; 1 reply brings a short digest of the spoken part. The picture is ignored, so a recording where talk is only background gives a thin result. Read the digest beside the video and confirm 1 key point.

Expecting the summary to describe the MP4 pictureOnly spoken words are summarized, so visuals are missedAdd notes about slides or screen content yourself
Sending an MP4 with a muted audio trackThere is nothing to transcribe, so no summary appearsCheck the MP4 has sound before sending
Expecting the summary to list every number said in the MP4Figures spoken in the video may be left outSearch the transcript for figures you need to keep
