Severe blocking and pixelation on 1080p YouTube upload. Please advise.
Hello,
When I upload my 1080p video to YouTube, it is very pixelated at the default 360 setting. I have tried both .mp4 and .mov with every imaginable encoding nuance. I have tried VBR, CBR, RGB color, YUV color, many different keyframing intervals, no keyframing, super high bitrates, etc. The video is still pixelating, and it is consistently worse at the same times in the video. I uploaded the most pixelated piece of footage of the video to a 5 second clip by itself, and it uploaded fine. I have tried the HTTPS/SSL Uploader, but my results were the same. The video plays flawlessly on my desktop. The footage was shot on a Canon MkIII, converted to Apple ProRes 422, and then edited in Final Cut Pro 7. Any advice is much appreciated! Thank you!
The pixelation is the worst around :26 and 1:29.
Here is the video link:

If you encode H.264 at 50,000kbps for high quality uploads and there are still issues, it’s simply YouTube mashing things.

Ashley, try reducing the number of quick cuts in the problem areas.
