Sound is half the edit
Silent generated video reads as fake. One layer of ambience and two effects fix that faster than any visual tweak.
Describe it like a foley artist
Name the source, the surface and the space. Footsteps on wet gravel beats footsteps every time.
Match it to a clip
Upload the video and the effect is generated against what happens on screen. Timing lands closer to the cut.
