Ok, so because direct export from Virb Edit to youtube does not seem to work well, and takes a lot of time, my general process is to use Virb Edit to export video to MP4 file, then upload the MP4 file to youtube.
I have been very disappointed with the result that ends up on youtube as however YT is encoding video, there is an incredible amount of distortion anytime there is much movement (like any action, from you action cam). The problem is not on the MP4 file, as it looks very good on my PC viewed in any media player.
Here is an example... you don't need to watch entire vid, you will see what I mean in the first 30sec, and then around the 45 sec mark I come to stop and everything becomes clear again. The best indication of what is happening is just to look at the gauge overlays. The distortion they have is correlated to what is happening with the image quality of the video:

I have tried 1080p 30fps, 720p in both 30/60fps with the same result. You can force YT to play in HD and it has no bearing on the issue.
Any ideas on what I can do to make the result a bit better? Is it because I only have the X instead of the XE with autostabilization and youtube is trying to auto-stabilize the image, even though I don't use that function on YT to do so?
