What people say about Flixier

I'm so relieved I found Flixier. I have a YouTube channel with over 700k subscribers and Flixier allows me to collaborate seamlessly with my team, they can work from any device at any time plus, renders are cloud powered and super super fast on any computer.

Anja Winter, Owner, LearnGermanWithAnja

My main criteria for an editor was that the interface is familiar and most importantly that the renders were in the cloud and super fast. Flixier more than delivered in both. I've now been using it daily to edit Facebook videos for my 1M follower page.

Evgeni Kogan

I’ve been looking for a solution like Flixier for years. Now that my virtual team and I can edit projects together on the cloud with Flixier, it tripled my company’s video output! Super easy to use and unbelievably quick exports.
