What Glyphcast is
Glyphcast turns a long video into short vertical clips. You upload a podcast episode, an interview, a webinar or a conference talk, and it returns the moments worth posting, cut to 9:16 and captioned.
The part that matters is how the moments are chosen. Scene detection finds the cuts, audio and motion analysis describe what is happening, the audio is transcribed locally, and the scoring runs against that real transcript rather than against a guess about what a good clip looks like. Every stage is described in full on the how-it-works page, including the one capability that is switched off.
