Even though I got the latest update from aplication manager there are 2 issues with producing video or audio on the export page.

#1 the speed of creating video or audio slows down if I choose lower bitrate. if I go higher quality (with the same project) production goes very fast

#2 this has been an issue since last year & hasn't been solved at all! the percentage rate STARTS at 20% and estimate time has to catch up
