Frequently Asked Questions

Clipping is the process of cutting short, shareable segments (typically 15-90 seconds) from a longer video or audio recording. Most creators clip podcasts, YouTube uploads, streams, and lectures, then post the clips to TikTok, YouTube Shorts, Instagram Reels, and Facebook Reels.

Manual clipping means scrubbing through the full recording to find good moments, trimming each one, writing captions, and reformatting for every platform. AI clipping automates all of that: transcription, moment detection, caption generation, and aspect-ratio reframing happen in minutes instead of hours.
