If panda uses a black background, his arms and legs will disappear too lol. Capcut's functions are different on PC and iPad. Autocut is a paid feature on PC, so I've never used it. The background on VRoidHub is the same, but maybe it's because the shooting method is different? You said that you can't use the video recording function of the Hub's photo booth. Panda was taken with the video recording function of the photo booth, so the image quality may be different.
