HI,naseemshanbour, thank you very much for your reply, i can to joint the group, by the link https://discord.gg/HZZ9XW , would you send it again? thank you very much.

looks like a linear srgb issue to me
you may have to change the source image to linear, or srgb
or play around with multiplying the plate by 2.2 or 0.45

I’ve just done this. In your second image of the video plate material, you need to drop in an srgb to linear converter after the top texture sampler, before the switch. Don’t use the pre-built node. There’s a composure processor that does srgb to linear with a custom node that contains shader code that you can copy/paste.

Hi, Dannington Thank you very much for your reply. i do not think that is the composure, the video feed from the blackmagic video card in Media Bundle is the same with wrong color, you are right this is the video plate material problem, but i can not fin the srgb to linear converter BP in the Unreal, how i change the video plate material to linear color , there is a linked , may be that will help, i will have a try when i get back to studio , Linear RGB in UE4 - Unreal Engine Forums
