ComfyUI Batch Video Loader
Batch-processes every video in a folder through a single-video workflow — no loop nodes or external scripts needed. Advances to the next video each time the prompt is queued, so a whole folder can be processed by queuing N times. Also includes an 'Ensure Even Dimensions' node to prevent odd-resolution encoder crashes with yuv420p/H.264 output.
