I have used Flexclip for some time to generate advertisements in different formats and different content templates, there is a learning curve to get the most out of it, once you become familiar with it, editing templates is very efficient.
But now, the fun part is, when exporting 1080p videos, the rendering is the most frustrating part of the entire process, i get crazy waiting times ranging from 10 min to 945 min, all in the same video rendering, i do not understand why it takes too long to generate a 1080p video 1 min long. staying in the page for "faster export process" makes no difference at all and it completely breaks your multitasking workflow ... this cannot be like that, it makes no sense!!
I want to like this app, but if i am unable to render videos properly, it becomes pointless, especially if you need to keep the tab open and stay on it for it to "work", besides having to wait who knows for how long, and if you need to make adjustments, good luck with that, you will need to start all over!
