when i render a simple video 1080p25 with constant bitrate high, 5.1, 80mb bitrate, in the exportfile i see pixel-"mud" every 3-4 seconds... on youtube it begins at 2 second, 5 and 13. on 720HD.. is like a blur effect for 1 sec, then constantly the video was sharper and blur again..
when i render the same with variable bitrate... no issue to see
when i render the same video on videodeluxe16, no issuewhen i use handbrake, no issue.
