Using WAN 2.1 image2video, we found that when the original-sized image is used as the first frame input, the output video appears enlarged and cropped around the edges.

The input key frame JPG has a native resolution of 832 pixels wide and 480 pixels high, but in the output video, the frame appears slightly enlarged, with cropping around the edges (the top and bottom cropping is particularly noticeable). What could be causing this?

Research direction
No files or tests are named. Reproduce the WAN 2.1 image2video case with the 832×480 JPG, then trace the image preprocessing and video frame-size handling to identify where scaling or cropping occurs. Done means the cause is confirmed and the unintended enlargement and edge cropping are corrected or clearly documented.
