why did you lock the thread about the video engine?
I’ve been working with the new update for some time and to be honest, the previous version was working better !
I’ve been reading about jerky video and stuff but… never had any issue with reasonably sized files on 5.1. When a file was huge , yes i had issues.
now in 5.1.1 on macpro , when i do a simple resize of my video window , everything freezes for a few minutes. the only way to fix that is to close and re-open the video window.
on pc , i had the same problem though it didnt froze the whole desktop. just the video.
