Sequencer - animation goes much darker than it appears on screen in the UE4 editor

Hi All

I’m looking for a bit of help

I am a relative novice with UE4 and and having some issues exporting an animation through Sequencer.

When I export a compressed video (75%) the animation goes much darker than it appears on screen in the UE4 editor (see screen shots),

When exporting as JPGs or an uncompressed AVI the colours seem to be OK.

I want to be able to export as a compressed AVI as the file sizes are much more manageable for sending out for comment without having to import into Premier and then re save.

Any thoughts on how to fix this?

I am just going to bump this, since I can’t find anything about this other then here.
In my case it turns a dark purple into a complete black color, regardless of the Compression Quality. Uncompressed videos have a file size of 5gb per 10 Seconds of 30fps footage.
