Re: Serious rendering issue

It looks strange that you choose "Main" profile in codec's settings, however in media info it shows "Baseline". Also, bitrate in media info is higher than in the codec's settings. Are you sure that this media is rendered with these codec's settings?

You can try to disable GPU usage by set "Encode Mode" to "Render Using CPU Only".
Also, don't forget to set "Video Render Option" to "Best" on the Project Tab.


P.S. I don't know if it helps in your players because I don't use VLC and QuickTime.
