HTML5 Color Changes on YouTube

[NetCode]

Hey there,

I've been using Sony Vegas Pro 13 to edit videos but have run into a problem.

Whenever I upload to youtube, the colors on my videos change when I cycle the youtube quality from 480p to 720p/1080p.
I'm using Windows 7 and Google Chrome which defaults to HTML5 with youtube - if I switch to Flash I don't have a problem (but this doesn't help my less technically inclined Chrome users who are viewing such videos).

480p:


720p:


Does anyone know how to fix this? I've only ran into like one other person on youtube where this problem also affects there videos.

Here's the video I found that also has a problem... Jump to 4 seconds, pause, then cycle between 480p and 720p - the problem only seems to show up on Windows Chrome Browser using HTML5:

Thank you!

Only windows chrome? I can't see any difference in mac safari and mac chrome with html5 video. So maybe just a windows chrome html5 bug.

That's correct but the problem I have is that it doesn't seem to effect all YouTube videos I look at, only mine and at least that other guy who I linked above.

I can confirm this problem also. When I change to 720P, then back to 480P, the red shield is obviously darker in the 480P version.(Chrome on Windows)

BTW, did you encode in the BT.709 colorspace?
