No trick, no trial
Prep and upload are free. Forever.
I'm a BlackBox contributor myself. I built Brollr because I needed it — and because nobody should pay to solve a technical compliance problem that shouldn't exist in the first place. Prep your clips to BlackBox specs, upload them over FTP, as many as you want, forever, for free.
The only paid feature is AI keywording — because running a video through an AI engine costs real money per clip. Even then, every user gets 5 free AI credits every month, so you can try it without ever paying. And if you prefer writing your own keywords, the free prep and upload workflow doesn't need AI at all.
New to stock footage? Start with the guide to filming stock footage with your iPhone: what BlackBox accepts, how to shoot so clips pass, and what the money looks like.

Free Workflow, Optional AI
Import free
Pick clips from your photo library, share them from any app, or pull them from the Files app: drone, SD card, USB drive, iCloud Drive. The picker filters by landscape or portrait and marks the clips BlackBox will reject, with the reason.
Prepare free
Brollr converts the frame rate, trims, strips audio, and exports at BlackBox specs, landscape or vertical. Slow-mo without quality loss. HDR kept or converted to SDR. All free, all offline.
Upload free
Batch FTP upload to portal.blackbox.global over TLS. Tap Upload and walk away. The upload preview can AirPlay the exact file that goes to BlackBox to your TV.
Looks optional, paid
Three color presets: Natural, Warm, Cool. Compare before and after with a divider in the preview, then export in SDR. Included with Basic and Pro.
AI Keyword optional, paid
Optional AI that watches your clip and writes a title, description, and keywords in seconds. 5 free credits every month. Basic adds 80 credits a month with a 7-day free trial, Pro 350.
CSV Export optional, paid
Export your metadata in the exact CSV format BlackBox expects. Pairs with AI keywording.
