I remember keying green screen footage in UE4 wasn’t great. Have there been any improvements in UE5 or even plug-ins to help get better keys? Or even better, any support for video with alpha channels?
keying greenscreen in material is still mediocre unless you have clean footage. much cleaner to export with real alpha from ae/resolve — prores 4444 or webm with alpha, or png/exr sequence — and play it with alpha in engine. ue5 still has no built in widget that composites video alpha properly, you have to wire media texture alpha to opacity yourself and get the blend right. alpha video player from fab Alpha Video Player - Transparent Video UMG Widget & UI Media Component (UE5) | Fab does that as a drop in UMG widget, 5 blend modes and color grading + volume/fade built in, so you dont need to build the keyer
