Frequently asked
What tools should I use to repurpose long-form videos into short-form content?
OpusClip for volume clipping, Descript for transcript-led clipping, Submagic for captions, and Vidmoat for reframing and captioning each clip on a timeline.[1][2][3]
How do I convert 16:9 to 9:16 without cutting off the speaker?
Use subject-aware reframing, which follows the person instead of cropping the centre. Vidmoat's auto reframe tracks the subject.
Can repurposing be automated end to end?
The mechanical parts can: cutting, reframing, captioning and per-platform versions. Choosing the moment is still judgement.
