What the cast may change
What can change is the figure: face, hair or fur, species, body proportions, and clothing or accessories from the photo. Identity should stay consistent through the sequence, though a turn of the head can still soften a feature. What stays is the room, the sofa, the punches, the guard, and the timing. Review those boundaries slowly before you treat the clip as finished.
An extra shoulder, a doubled arm, a second figure near the cabinet, or a cut that was not in the source means look again. Say that the sequence is a cast scene when the context matters. Results vary from one generation to the next.
Permission, sound, and the credit line
The soundtrack comes from the performance. It is not a voice taken from the subject in the photo, and the upload does not create one. Listen from the first guard through the last punch before you download. A silent skim can hide a mismatch you would have caught with the track playing.
Permission stays with you. Use a human or animal you are allowed to place in the scene, and do not treat the file as clearance for the music or the footage. A new length, or a scene you describe yourself, goes to /video. Saved results remain in My creations.
