How AI YouTube Shorts Generator works
- 01
Upload a long video
Drop in an MP4 or MOV between 1 and 30 minutes long, up to 1 GB. Podcasts, interviews, vlogs, webinars and talks work best because the tool reads what is said.
- 02
Choose how many clips and how long
Pick 3, 5 or 8 clips and a length (15–30s, 30–60s, Up to 90s). Choose Fill to crop one speaker to 9:16, or Fit to keep the whole frame on a blurred background, and pick a caption style: Bold, Clean or Boxed.
- 03
AI picks the best moments
The video is transcribed with word-level timing, the moments that make sense on their own are selected, and each is cut to a 1080×1920 clip with word-by-word captions and a hook title.
- 04
Review and post
Every clip gets a virality score out of 100 and is saved to My Videos. Download it for YouTube Shorts, TikTok or Reels, or open it in the editor first.
Why creators use it
- Turns one long recording into several Shorts in one run, without scrubbing the timeline yourself.
- Animated, word-highlighted captions burned in, in three styles, so clips work with the sound off.
- A hook title on each clip and a virality score to decide which one to post first.
- Priced by the length of the source, not the number of clips: a 10-minute video is 10 credits and a 30-minute one is 30.
- Clips that fail are refunded automatically.
- Want new Shorts instead of cut-downs? Generate original 9:16 clips from a prompt or photo in the same account.
Use cases
- Cut a weekly podcast episode into Shorts for the days between episodes.
- Turn a webinar or product demo into short clips for YouTube Shorts and LinkedIn.
- Repurpose vlogs and interviews into TikToks and Reels with captions for silent viewing.
- Find the strongest moment of a talk by comparing the virality scores of the clips.
Frequently asked questions
How do I turn a long YouTube video into Shorts?
Open Long to Shorts, upload the video file (MP4 or MOV, 1 to 30 minutes), pick 3, 5 or 8 clips, a length and a caption style, and start. The clips appear in My Videos with captions and a hook title, ready to upload as YouTube Shorts.
Can I paste a YouTube link?
No. Upload the video file itself. Use a video you own or have the rights to repurpose.
How much does it cost?
1 credit per started minute of source video (minimum 3), whatever the number of clips. A 10-minute video costs 10 credits and a 30-minute video costs 30. Credits come from one-time packs with no subscription.
How long are the clips?
You choose: 15–30s, 30–60s, Up to 90s. Every clip is vertical 9:16 at 1080×1920, which fits YouTube Shorts, TikTok and Instagram Reels.
Which videos work best?
Videos where people talk: podcasts, interviews, vlogs, webinars, talks and tutorials. The moments are chosen from the transcript, so music-only or silent footage gives the tool little to work with.
Are the captions editable?
Captions are burned into the clip, so the wording cannot be edited afterwards. Before you start, choose the style (Bold, Clean or Boxed) or turn captions off.
