AgentReel has launched a browser-based AI B-roll editor that accepts up to 500 clips and 20 GB of footage per project. Creators supply their footage and narration, let the system select supporting shots, and export a captioned MP4 in vertical 9:16 or horizontal 16:9 format, according to the company’s product page.
The first cut is free for videos up to 60 seconds using up to 50 clips. Further processing uses purchased credits, with costs displayed before a job starts. Uploaded footage is retained for seven days, so this works as a short-term editing space rather than a permanent home for a clip library.
AgentReel’s homepage is marked as updated on October 26, 2026, but provides no separate launch timestamp. Its most useful proposition is concrete: take a folder of unsorted footage and produce an initial edit organized around what the narration says.
From Footage and Narration to a Finished Cut
B-roll is the supporting footage shown while someone speaks. For a creator explaining a morning routine, that might mean shots of making coffee, catching a train or opening a laptop.
AgentReel’s workflow starts with those existing assets:
- Upload clips or photos. The browser prepares the footage, compressing heavy files such as 4K iPhone video into lighter 1080p copies before upload.
- Supply the narration. Creators can paste a script and use an AI voice, or provide their own recording.
- Choose the presentation. Settings include fast, medium or slow pacing and one of seven caption styles.
- Generate and export. The system matches shots to the narration, assembles the sequence, times captions and produces a vertical or horizontal MP4.
The vendor’s documentation says there is nothing to install. Browser-side preparation is useful for reducing transfer size, but the clips are still uploaded. This is not an entirely local editing workflow.
I’d treat the script as the starting point for evaluating this product. A system matching footage line by line has a clearer task when the narration names specific actions or subjects. That is a practical inference from the documented workflow, not a tested claim about which writing style produces better results.
The 500-Clip Limit Has a 20 GB Companion
AgentReel publishes several limits that need to be considered together:
| Item | Published support or limit |
|---|---|
| Clips per project | Up to 500 |
| Total footage per project | Up to 20 GB |
| Individual video file | Up to 500 MB |
| Video formats | MP4, MOV and M4V |
| Photo formats | JPG, PNG, WebP and HEIC |
| Photo treatment | A four-second clip with a slow zoom |
| Heavy footage preparation | Browser compression to a lighter 1080p copy |
| Export shapes | 9:16 vertical or 16:9 horizontal |
These details come from AgentReel’s product FAQ.
The clip count is only one ceiling. Using decimal units for a rough calculation, spreading 20 GB across 500 clips leaves an average of about 40 MB per clip. At the individual-file ceiling of 500 MB, roughly 40 files would consume that same total allowance.
That arithmetic matters for creators with long takes. A library of hundreds of short phone clips fits the intended shape of the product more naturally than hundreds of large interview recordings. Browser compression may reduce transfer size, but creators should still check both the total project allowance and the individual-file limit.
The 1080p preparation step also deserves attention. It means the uploaded working material can differ from the original 4K footage. Keep the source files if a later edit needs the original resolution or more room for cropping.
Likewise, support for both output shapes does not tell us how well the system will reframe every shot. A subject near the edge of a horizontal image may need attention in a vertical cut.
How AgentReel Says It Selects and Cuts Shots
AgentReel says its AI examines what each part of a clip shows, along with shot size, camera steadiness and scene grouping. It then matches footage to the meaning of each narration line. Shaky, blurry and off-topic material receives a lower ranking.
The assembly stage follows more explicit rules. According to the product page, it:
- Uses shots of roughly 1.5 to four seconds, depending on the selected pace.
- Places cuts on a 30-frames-per-second grid.
- Prefers unused sections before repeating footage.
- Prevents a clip from immediately following itself.
The repetition rule is narrower than a promise that footage never repeats. Longer narration or a small relevant shot pool can still require reuse.
AgentReel claims a script lasting a few minutes, paired with a few hundred clips, is usually ready in about 20 minutes, with upload and rendering accounting for most of that time. The speed and editing-quality claims are vendor-reported; the cited material contains no independent performance testing.
My view is that the selection step is the feature worth scrutinizing. Frame-aligned cuts and readable captions are useful, but they cannot rescue a shot that contradicts the narration. For a trial, include several visually similar clips with different meanings and inspect whether the system chooses the right moment, not merely the right general subject.
What the Free Cut Covers, and What Credits Leave Unknown
The free first cut covers up to 60 seconds and 50 clips. That is one-tenth of the advertised maximum clip count, so it provides a way to judge shot selection and captions without proving how a full 500-clip project will behave.
AgentReel says every tool displays its credit cost before processing and automatically refunds credits for a failed job. However, the public product page does not publish a B-roll pricing table or a fixed credit cost per finished minute. The available documentation therefore cannot support a reliable dollar estimate for a particular project.
The site also advertises a daily check-in worth 15 free credits, expiring at 00:00 UTC. Its free-account description names Z-Image and video templates. That offer should not be read as a promise of a fresh B-roll edit every day.
For a useful first trial, I’d choose a representative 50-clip subset: some strong shots, some weak ones and a few near-duplicates. An easy folder of perfectly selected footage would reveal less about the screening feature.
Before paying, check the displayed charge for the actual operation you want. Automatic refunds address failed processing; they do not establish that a successfully rendered edit will meet your expectations.
