Made by a BlackBox contributor

Free BlackBox Prep.
Right from your iPad/iPhone.

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.
