Reddit user big-boss97 shares a hands-on test of video character swap on consumer hardware. Instead of swapping characters, they inverted the test and prompted the model to replace the wooden boat in the scene.
Settings and hardware: 640x480 resolution, 10 minutes 33 seconds render time, RTX 4070 with 8GB VRAM and 64GB RAM — a useful baseline showing this kind of video object replacement is feasible on an 8GB card.
