Image Blend Node error

Hi, I'm traying to blend two videos one as a background and another as an overlay is a Hud animation but I'm getting this error it supposed to process the video no matter their frame count or size just process it as a layer on top of another.
Error occurred when executing ImageBlend:

The size of tensor a (63) must match the size of tensor b (278) at non-singleton dimension 0
