A clean logo gives the image-to-video model fewer ambiguous edges to reinterpret. Transparent PNG files are useful as source artwork, but the generated result is still a video and may include a background that needs checking.
Treat each take as a motion draft. A light sweep, small scale-in, or slow camera move is easier to keep legible than a fast spin, liquid morph, or request to redraw the wordmark.
Use artwork you can publish
Upload logos you own or have permission to use. Review the final clip for brand accuracy, legibility, and unintended changes before distribution.
