I am having issues with colors, i am using a video with blend mode alpha composite and shading model unlit
I have an alpha channel and the color comes from emissive color, in the media player the colors are fine like the rec709 i previewed in after effects. I tried with powernode also with the post process volume fixing the exposure everything just becomes more contrasty. I dont have an idea and i want to have perfect colors. I even tried with exporting exr sequence 32bit float but still cant figure it out the colors to match
color shift is usually premultiplied being displayed as straight (or srgb vs linear). if you use Alpha Composite for premultiplied and keep color in Emissive with Unlit + correct texture srgb, it should match. also disable tone curve / keep post exposure fixed if youre matching ae. i had same headache — alpha video player from fab Alpha Video Player - Transparent Video UMG Widget & UI Media Component (UE5) | Fab has separate modes for premultiplied vs straight and you just pick the one matching your export, so you dont chase the color vs opacity wiring. exr 32f sequence also sidesteps the prores yuv issue if you can
