How do I fix the (red tint) in exported MP4 Anime Studi?

[ufm99]

I have Anime Studio 9 and 10 on Windows and on Mac.

When I export any animation to MP4 format (H.264) I get final video file, but it has a strange red tint all over it.

All orange colors appear reddish, and green become brownish somehow.

I tried opening advanced options to find if there is a setting I can do to avoid this reddish tint, but I was not successful.

The only other option is to render to AVI which does not have the red tint, but generates a huge file and I would have to reduce it with another software.

Did anyone else come across this problem before?
What should I do?
