I will be exhibiting a looped 11 min. HD video in a gallery in Berlin in July-Aug. I am coming from the States and looking for the easiest (lightest) and least expensive way to project the video onto the floor of the gallery. I am considering putting the video onto a flash drive. Are there decent projectors that take USB video flash drives? Or is there a better way to do this? I’m new to projecting videos, so am at the beginning of the learning curve!
