I have been using PE10 for a year and have just installed PE11.
In PE11 when I render my footage from my Go-Pro camera, which is 1920x1080, the rendered footage details on the hard disk are 960x480 at a bitrate of 6480kbps?
Any suggestions why not 1920x1080?
It stayed 1920x1080 at bitrate 25920kbps in PE10.
You're talking about rendering your timeline, right?
In order to speed up previews on your timeline, Adobe sometimes renders high-def video on the timeline at a slightly reduced resolution or quality.
This has no effect on your output video, which is based on a combination of your Project Settings and your Publish & Share selection.
