A 2-hour podcast in about five minutes.
Never mid-sentence
Clips start on a real hook and land on a real payoff.
Turn a long video into shorts — without scrubbing through it
The hard part of short-form was never the editing. It's finding the ninety seconds worth editing inside three hours of talking. Doing that by hand means watching the whole thing back with a notepad, and most people simply don't — which is why so much good long-form content never becomes anything else.
CaptionX Clips is an AI clip generator that does the watching for you. Upload a podcast, an interview or a long YouTube video and this AI clip maker reads the entire transcript, finds the moments that stand on their own, and hands them back ranked — ready to post as YouTube Shorts, TikToks or Reels. No timeline, no scrubbing, no guessing. Drop the file in and it works as a YouTube clipper: it reads the whole video, then gives you every clip worth posting instead of a timeline to trawl.
How the AI clip generator works
- 1
Drop in a long video
An MP4, MOV or M4A up to three hours — a podcast, an interview, a webinar, a stream VOD. The audio is extracted in your browser and only that is uploaded, so the video file itself never leaves your machine.
- 2
It reads the whole transcript
We transcribe to word-level timestamps, split the transcript into real sentences, then read it in overlapping windows so a moment is never missed because it straddled a boundary.
- 3
Every clip comes back ranked
Each candidate is scored on hook, payoff, whether it stands alone without context, emotion, quotability and pacing. Weak openers and rambling starts are penalised, not rewarded.
- 4
Watch them all, keep what you want
Nothing is hidden behind a paywall before you've seen it. Play every clip in full, then keep the ones you'd actually post.
Clips that never cut mid-sentence
The single most common complaint about AI video clipping is that the clips start mid-thought and end mid-word. It happens because most tools ask a model for start and end timestamps, and a model asked for a number will happily give you one that lands in the middle of a sentence.
We don't ask for timestamps. The transcript is split into sentences first, and the model may only choose which sentences a clip contains — it never sees a number at all. The server turns those sentences back into seconds. A clip that begins or ends mid-sentence isn't unlikely here; it's not expressible.
The same pass throws out openers that sound like the middle of a conversation — a clip that starts "And so to your point…" is a clip nobody watches, however good the payoff.
A YouTube clip maker built for podcasts and long-form
Long, conversational, two-person audio is the hardest case for an AI video clipper and the one we built for. As a podcast clip maker it handles the things that actually break other tools: a guest who never pauses, a host who interrupts, a story whose punchline lands ninety seconds after the setup.
Because it reads the transcript in overlapping windows rather than fixed chunks, a moment that straddles the boundary between two sections is still found. And because clip length is a hard limit rather than a hint, picking "Shorts" means every clip you get back really is between 15 and 30 seconds.
How CaptionX compares to other AI clipping tools
We've described the alternatives by how they generally work rather than naming and mis-stating any one product's current plan. Check the pricing page of anything you're comparing us against.
| CaptionX Clips | Typical AI clipper | |
|---|---|---|
| Charged per uploaded minute | No — a 3-hour podcast costs the same as a 10-minute one | Yes — most tools meter the source video, not the output |
| See every clip before you commit | Yes — all clips play in full, free | Usually previews or watermarks until you pay |
| Clips start and end on a sentence | Always — the AI picks whole sentences, never raw timestamps | Not guaranteed — mid-sentence cuts are the most common complaint |
| Your video is uploaded | No — audio is extracted in your browser | Usually the full video file |
| Charged when it finds nothing good | No — an empty result costs you nothing | Yes — the minutes are spent either way |
Finish the clip in the same place
A clip isn't done when it's found. Once you've got the moment, the rest of CaptionX picks it up: add animated captions, translate the subtitles into 60+ languages, burn them into the video, or cut the dead air if you're finishing in Premiere Pro. Editing in Premiere already? The same clip finding is coming to the CaptionX Premiere Pro extension.
Frequently asked questions
What is an AI clip generator?
It's a tool that reads a long video's transcript and finds the short, self-contained moments inside it that are worth posting on their own — then hands them back ranked, so you don't have to watch three hours back with a notepad. CaptionX scores each candidate on hook, payoff, whether it makes sense without context, emotion, quotability and pacing.
How do I turn a long video into shorts?
Upload the video, pick a clip length (15–30s for Shorts, 15–60s for Standard, or 45–90s for longer cuts) and hit Get clips. Every clip that comes back sits inside the range you picked — it's a hard limit, not a hint — and you can watch all of them before deciding what to keep.
How is this different from Opus Clip?
Two ways. First, we don't meter the video you upload: a three-hour podcast costs the same as a ten-minute one, where most tools charge per source minute whether you use one clip or fifteen. Second, our clips never start or end mid-sentence, because the AI picks whole sentences rather than raw timestamps — mid-sentence cuts are the most common complaint about AI clipping, and here they're structurally impossible rather than merely unlikely.
Does it work as a podcast clip maker?
That's what it was built for. Long, conversational, two-person audio is the hardest case — a guest who never pauses, a host who interrupts, a punchline that lands ninety seconds after the setup. The transcript is read in overlapping windows so a moment that straddles a section boundary is still found.
What happens if it doesn't find anything good?
You pay nothing, and it doesn't count against your daily allowance. We'd rather return an empty list than pad it with clips you'd throw away.
Is the score a prediction of how many views I'll get?
No, and we won't pretend otherwise. It ranks clips within your video on hook strength, whether the idea pays off, and whether it makes sense without context. Nobody can honestly predict views.
Does my video get uploaded?
No. The audio is extracted in your browser and only that is sent for transcription. The video file itself never leaves your machine.
What files can I use?
MP4, MOV or M4A, up to three hours long. We deliberately restrict input to formats we can reliably read in the browser rather than accepting anything and failing halfway through a two-hour upload.
