I like Flixier because I can use it anywhere I go and I don`t need a lot of computer requirements but great internet connection. I like how fast it is when it comes to rendering videos and still have the opportunity to continue or start another project while waiting. I appreciate the continuous updates and adjustments because it is necessary for a video editing tool.

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.

What I like most about Flixier is the flexibility to edit the captions, both in terms of the text and the time where it starts and finish showing it. It gives you full control.

This online free program was extremely easy to use, implement, and integrate into my 9-12th grade tech classes. The projects turned out great and were easy to export. I liked having multiple ways to upload pictures. The software was also easy to understand.
