adding videos and image sequences as planes ?

hi im thinking about switching from blender eevee to ue for my movie project becasue i run into various limitations in blender.

Can i add image sequences and/or video files to a plane and play them back in acceptable performance ? this would be muzzle flashes, fire, explosions , smoke and dust footage and 2d animated image sequences with the animation objects (characters, monsters and warmachines) behind them.

how many can i add until the performance drops out or will ue cache them nicely ?
