Convincing movement does not necessarily make an accurate product ad. Compare Hailuo and Kling on product shape and action as well as camera movement. Use your product to test movement, repeatability and revision quality.
Separate camera and product movement
First keep the product still while the camera moves slowly. Then test a simple real product action. This separates perspective issues from action issues. A dramatic camera move can conceal changing geometry.
Use clear approved references and a simple first scene. Inspect the start, middle and end, including brief errors that may affect playback or product understanding.
Assess the whole sequence
Test whether the next shot matches colour, light and scale, and include editing and sound work. One successful clip establishes only that clip.
Record versions and settings. Repeat the action test after relevant changes, and document where real footage gives a more reliable demonstration.
