You already have the long video. The job is clip, reframe 9:16, caption, export. This URL still ranks in search; we rebuilt it so the seven-tool promise is 2026, not a Listnr press list from last year.
- Opus Clip — virality score, auto-reframe, the default if you want a machine to guess the moment.
- Vizard — interviews and podcasts; speaker-aware cuts and social packaging.
- Captions — if a human is still going to touch the edit. Also on our UGC list.
- Pictory — webinars and scripts to vertical; storyboard people like it.
- InVideo — templates, stock, a full editor when the AI cut is 70%.
- VEED — subtitles and cleanup with a UI you will not fight.
- Kapwing — smart B-roll and team browser editing. The Swiss army knife, not the scalpel.
Listnr ClipMaker was #1 on the old page. Listnr is still a serious TTS studio; clipping leadership moved to Opus and Captions. We would rather update a ranking than defend a friendship.
If the footage does not exist and you need a synthetic presenter, that is AI UGC. If you are clipping adult companion promo (live-action clips, Dream Clips), read the platform ToS twice and start from the companion ranking — those exports are usually personal-use, not YouTube inventory.
