Comparison
Submagic styles the clip. Cutroom decides what the clip is.
Caption tools dress a clip you have already cut. Submagic does that quickly and the type looks right. The cut underneath is still an evening of your life. Here is who each tool suits, what one batch costs, and how Cutroom decides the cut itself.

- caption packs shipped with Cutroom
- 6
- batch: transcript, director pass, b-roll search
- 100 CR
- b-roll coverage ceiling by pace
- 40-52%
Submagic finishes a clip. Cutroom decides what the clip is.
Drop in a finished clip and get word-level captions with the styling short-form audiences expect, in a couple of minutes.
The emphasis handling is the part people buy. A number that pops. A keyword that lands. A rhythm that keeps a muted viewer reading.
It bolts onto a workflow you already have. Cut in whatever you cut in, then run the file through for the finish.
That is a good tool for the last ten percent of the job. The other ninety percent is the cut.
Something has to decide which sentence goes, where the footage sits and how fast the whole thing moves. Today that something is you, on a timeline, in an evening.
Cutroom does that part and ships the captions with it. One raw take in, one finished 9:16 MP4 out, six caption packs to choose from on the way.
One batch is 100 credits and covers the transcript, the director pass and the b-roll search. Export is 20 credits per finished minute, so a second version of the same idea costs pocket change.
Perfect captions on a weak cut still read as a weak cut
Captions are the last layer. They cannot delete the sentence that dragged for four seconds in the middle.
They cannot move footage onto the claim that needed showing. They cannot fix a read that sagged at second nineteen.
So the work upstream stays yours. Something assembled that clip, and that something was probably an evening.
The failure mode is common. Bold, perfectly timed type on an ad that still gets scrolled past, because the structure underneath was never fixed.
Structure decides whether somebody watches at all. Captions decide whether they can follow it muted.
Both are necessary. Only one of them can be added at the end.
Cutroom starts at the raw take and does both in one pass. That is the whole argument on this page.
Where each tool joins the chain
A caption layer joins after the cut exists. Cutroom joins at the raw take and hands back the finished file.

This is the whole editor
Highlight a phrase and a clip lands on those exact words. No timeline, no keyframes, no layers.
Delete the line that dragged and the whole cut recomputes
Upload one take up to three minutes. Cutroom transcribes it and drafts the cut. Back comes a 9:16 MP4 with captions burned in.
Highlight a phrase and a clip lands over exactly those words. Swap it, or search millions of free ones if the draft picked wrong.
Delete the flat line and every boundary after it recomputes. Change the pace and the machine re-cuts the whole piece.
Emphasise a single word so it pops in the captions. Same finish a caption tool gives you, arriving with the cut instead of after it.
Six packs cover the look: clean UGC, bold impact, karaoke flow, editorial, fast native and minimal lux. Colour, weight, size and position all switch from a menu.
No timeline, no keyframes, no layers. None of those decides whether the ad works.
Trim the opening or the ending. Write the headline over the first three seconds, or take the one the director pass drafted.
- Coverage capped at 40, 45 or 52 percent so it stays a person talking
- Five ways a clip enters: cut, whip, punch, glitch or sweep
- Fix a mis-heard word and the burned-in captions follow the correction
- Export another cut for 20 credits a minute without re-running the batch
What Cutroom expects: a raw take, three minutes, vertical out
It starts from an unedited take. That is the design, because the cut is the part it is doing for you.
Source is capped at three minutes and the export is a 9:16 MP4. That is the shape TikTok, Reels, Shorts and Meta Stories all run.
There is no timeline underneath. A caption cannot be nudged four frames and a clip cannot be dragged, which is why the edit takes four minutes.
Nothing of yours is stamped onto the export. No logo, no closing frame.
Somebody has to be on camera, or has to own a photo the avatar module can drive at 320 credits a minute.
Those are the facts you plan around on day one. Everything else the ad needs arrives in one pass.
Which half is missing: the finish, or the cut underneath it
Two questions settle it. Do you already have finished clips? Is captioning the only step left?
Yes to both, a caption tool covers you. No to either, the missing half is the edit, and that is the half this does.
The arithmetic that makes the edit worth automating: winners are 5 to 8 percent of creatives, per Motion's analysis of 550,000+ Meta ads.
At six a month you are drawing under one winner. At thirty you are drawing two, from the same face and the same offer.
The count only moves if a second attempt costs minutes rather than an evening. Twenty credits a minute is what makes that true.
Seven days, 300 credits, no card, which covers two finished one-minute ads from fresh takes.
One finished minute from a fresh take is about 120 credits, so the trial covers two of them before a card is entered.
Submagic and Cutroom, row by row
Row one goes to the caption tool. Everything below it is the edit that had to happen before the captions could go on.
| Submagic | Cutroom | |
|---|---|---|
| Finish an already-edited clip | Its exact job | Expects a raw take |
| Turn a raw take into an ad | You bring the cut | One batch, 100 CR |
| Captions with no second app | It is the second app | Six packs, same pass |
| Decides what to cut | Styles what is there | Drafts the whole cut |
| Footage on a chosen phrase | Some b-roll assistance | Highlight, clip lands there |
| Cut rebuilds when a line goes | Re-export from your editor | Delete, and it recompiles |
| Pace change re-cuts everything | Captions only | Coverage ceiling moves too |
Questions people ask
- Can I use Cutroom only for captions?
- You can, and the batch is 100 credits because it also transcribes, drafts a cut and searches b-roll. Most people who try that end up using the cut as well, because it arrived anyway.
- How good are the caption styles compared to a dedicated tool?
- Six packs ship, with colour, weight, size and position adjustable, plus per-word emphasis. That covers most ad looks. It is a menu rather than a design system, and a caption specialist offers more control over the type itself.
- Does the b-roll get chosen for me?
- The director pass places it in the draft, capped at 40 percent on chill, 45 on normal and 52 on fast. You then move it by highlighting a phrase, swap any clip, or search millions of free ones for a better one.
- Is it right for every clip?
- It is built for takes that have not been cut yet. If your edits are already done and only need dressing, a caption tool is the cheaper step. Bring the raw takes here.
A caption tool dresses the cut you made. Cutroom makes the cut, places the footage on the claim and burns the captions in, from one raw take.
