Stopping youtube compression

Yootoob vids are heavily compressed, its just a fact and you can't do anything about it other than not put them on there.

Its designed for streaming so its going to get compressed to reduce filesize and server load, buffering stutter, etc.

If you want your vids preserved in original quality you'll have to upload them to a filesharing site or include a link in your YouTube vid description to a decent quality download.

Change it to constant framerate, you really dont want to be re-encoding variable frame rate

This does seem to be the most likely culprit.

You video seems to exhibit lots of compression artifacts during the fast motion frames which isn't going to help when it's re-compressed and creates that smearing of the colours. When recording the video you need to make sure it's uncompressed or lossless compressed frames and when reduced in size uses a two-pass encoder. There's also a load of more advanced stuff you can do but it's too much to go into here.

That's a little extreme, 1080p uncompressed video is enormous, YV12 @ 30fps is going to be 5.6GB per minute which can saturate a hard disks throughput. If a video is going to be edited then using an intraframe codec like MJPEG makes sense but uncompressed or even lossless isn't worth it for this kind of application.
