Selection, surface or structure: Cutroom builds the structure
Three tools, three verbs. Opus Clip selects a clip that already exists. Submagic improves the surface of one you chose. Cutroom builds a structure that did not exist, from one purpose-shot take. This page shows what each verb does to a video and what a finished ad costs. By the end you will know which verb your folder is asking for.

Opus Clip wins the archive, and its clips open mid-thought
Podcast, webinar, stream, panel, interview. If long recordings pile up as a by-product of something you were doing anyway, Opus Clip is the buy.
It transcribes the whole recording, proposes segments, scores them, reframes to vertical and hands back a stack of candidates. Doing that by hand is the least pleasant hour in short-form.
Treat the scores as a shortlist rather than a verdict. Twenty candidates arrive and your judgement is the filter. That costs a few minutes each and appears on no pricing page.
Yield decides whether it pays. A structured interview gives up several usable clips an hour. A meandering solo recording gives up one, and the meter charges the same for both.
Where it runs out is the opening. A clipped segment starts mid-thought because it was mid-thought. In paid media, where the first three seconds decide everything, a fragment with no hook starts behind and stays there.
Submagic finishes the surface, and leaves the structure alone
Captions done properly. Timing, weight, the way a word lands, the small motion that keeps an eye moving. It reads as a tool made by people who care how short-form looks.
Count the minutes it returns. Twenty minutes of hand-captioning becomes about ninety seconds. Across thirty clips a month that is most of a working day.
It is honest about its scope. It does not decide what your video says, so it slots into almost any workflow without replacing one.
Where it runs out is structure. If the clip rambles for eight seconds before the point arrives, you get well-captioned rambling.
Ads fail on structure far more often than on surface. Buying a finishing layer to rescue a weak hook is the most common misdiagnosis in this category.
This is the whole editor
Highlight a phrase and a clip lands on those exact words. No timeline, no keyframes, no layers.
Cutroom builds the structure, from a take shot on purpose
Cutroom is the only one of the three that expects you to record something deliberately. One take, three minutes at the outside.
The machine transcribes it, plans a cut, searches millions of free clips for b-roll and returns a finished vertical ad. Then you direct it in words.
Highlight a phrase and a clip lands over exactly those words. Delete a line and the cut rebuilds. Move the pace and the whole thing re-cuts. Captions arrive burned in, from one of six packs.
The opening is the part nothing else on this page can give you. It is directed from the first word rather than inherited from the middle of a conversation.
A thirty-second ad costs 110 credits from upload to file. The iteration in between is free, so a change of mind is not a purchase.
The plain limits: three minutes is enforced at upload, 9:16 is the only export, there is no timeline for a four frame nudge, and nothing here mines a back catalogue.
Source length, on one scale
The three minute ceiling is a hard stop at upload, not a setting. Anything to the right of it belongs to a different tool.
- Cutroom source ceiling3 min
- A clip you would already post1 min
- Typical podcast episode45 min
- Typical webinar recording60 min
Diagnose the failure first: long, unfinished, or nothing in three seconds
Ask what each tool does to the structure of the video and the argument ends.
Opus Clip selects a structure that already existed inside a longer recording. Submagic improves the surface and leaves the structure as you made it. Cutroom builds a structure that did not exist, and lets you change it by editing words.
So the diagnosis comes first. If your videos fail because they run long, buy selection. If they look unfinished, buy surface.
If nothing happens in the first three seconds, that is a construction problem, and construction is the only one of the three verbs that fixes it.
Price all three the same way. Cost per clip you would actually post, at your own keep rate, with review time included. That single number settles it faster than any feature list.
What building a structure looks like
The whole loop runs on words. Nothing in it is a track, a keyframe or a layer.

Buy for the material you produce weekly, not the material you plan to
The intention to start recording long-form once the new setup arrives is where most unopened subscriptions come from.
The trial here is 7 days and 300 credits with no card. That is enough to batch two takes and export both. Opus Clip and Submagic run their own free tiers.
Try them in the order your diagnosis suggests rather than by brand recognition. An evening spent on the wrong one tells you nothing about the problem you have.
Wanting every one of these jobs done is normal. Expect two subscriptions in that case, and decide which one is the everyday tool.
Count the recordings on your drive that run past ten minutes. That number, and not a feature grid, tells you which of the three to open tonight.
The rows below settle the archive question on their own. Two go to Opus Clip. The other six are what a finished ad needs.
- You record long conversations weekly and need short pieces. Opus Clip, and it is not close.
- Your clips are well written and look unfinished. Submagic, at about ninety seconds each.
- You film short reads to advertise and the editing never gets done. Cutroom, 110 credits an ad.
- You want an opening built on purpose rather than inherited. Only construction does that.
Opus Clip and Cutroom, row by row
Two rows go to Opus Clip, and they decide it if long recordings already exist. The other six decide a cold paid feed.
| Opus Clip | Cutroom | |
|---|---|---|
| Mining long recordings | Ninety minutes in, clips out | Three minute ceiling |
| Needs no new filming | Uses last year's archive | Somebody records a take |
| Builds an opening hook | Clips open mid-thought | Directed from the first word |
| B-roll on the words | Reframes, does not cut away | Clips land on phrases |
| Change the pace of the cut | Trim inside one clip | Whole edit re-cuts |
| Captions burned in for mute | Styling is a separate pass | Six packs, one tap |
| Cost of a change of mind | Re-upload the source | Re-cut free, export bills |
| Cost you can forecast | Billed on input minutes | 100 credits a take |
Questions people ask
- Can I clip a long video and then cut it in Cutroom?
- Yes, and it is a reasonable pipeline. Pull a segment under three minutes, upload it, and direct the ad on the transcript. A segment from the middle of a conversation rarely has a hook, so you may need to record a fresh opening line.
- Does Cutroom do captions as well as a dedicated captions tool?
- It ships six caption packs with control over colour, weight, size and position, plus word emphasis. That covers most ads. If captions are your craft and you want frame-level styling, a dedicated tool goes further.
- What does this cost to run for a month?
- For Cutroom: a batch is 100 credits and an export is 20 credits per output minute, so a 30-second ad costs about 110 credits end to end. Basic at $39.99 a month carries 2,500 credits. The others publish their own plans and change them.
- Which one produces ads that convert?
- The tool decides how fast you can test. The script, the offer and the hook decide whether anything converts. Benchmarks put the share of creatives that carry real spend at 5 to 8 percent, per Motion's analysis of 550,000+ Meta ads.
- I have eighty hours of podcast. Is this the wrong tool?
- For mining that archive, yes. Buy Opus Clip and pull segments from it. Then bring any segment under three minutes here when it has to become a paid ad, because that is where the opening gets directed.
Selection and surface both start from a video that already exists. Cutroom builds the one that does not, and hands it back finished.
