Turn a podcast episode into short clips
Video podcasts are full of moments that work on their own. Paste the episode's YouTube link or upload the file, and we pull out the best 5–10, with captions for people watching on mute.
No credit card needed
Works with

- YouTube live replays
- MP4, MOV and other video files
- Up to 30 minutes long
How it works
1
Add the episode
A YouTube link or a video file. Episodes can be up to 30 minutes, so upload a section of longer ones.
2
We find the moments
Strong opinions, a good story, a line that lands. Each gets a virality score and a reason.
3
Share them between episodes
Download the clips and post them to keep your audience listening all week.
Everything you need to turn one video into many clips
Paste a link and Onyx finds the moments worth posting, cuts them to vertical, adds captions and tells you which ones should do best.
Find a specific moment
Tell the AI what you're after, like “the money advice” or “the funniest stories”, and it looks for those moments first.
Virality score with a reason
Every clip gets a score out of 100 and one plain sentence on why it should work, so you know what to post first.
Captions that pop
Captions timed to every word, in 5 styles: from bold with the spoken word lit up, to plain and quiet.
Smart framing
Face tracking follows the speaker. Split screen puts a facecam over the action, and Fit shows the whole picture on a blurred background.
Remove pauses
Long silences between words are cut down to a short breath, and the captions stay in sync.
Paste a link or upload
YouTube videos, finished live streams and your own video files, up to 30 minutes long.
Clips as they finish
Watch and download each clip the moment it's ready, while the rest are still being made.
Private by default
Only you can see your videos and clips, and the files delete automatically after 7 days.
Questions
- My episode is longer than 30 minutes. What can I do?
- Cut it into 30-minute parts and add each one as its own video. Each part counts as one video.
- Does it work for audio-only podcasts?
- Not yet. It needs a video file or a YouTube video, because the clips are vertical videos.
- Can I tell it what to look for?
- Yes. Under More options on the dashboard there's an "Instructions for the AI" box. Write something like "focus on the funny moments, skip the intro" and it picks with that in mind.
