Check hands and product contact in AI video

A convincing product grasp has a sequence: the hand approaches, makes contact, applies force, moves the object and releases it. Inspect that sequence rather than judging a single attractive frame. Fingers that look natural before contact can still slide through packaging when the product starts moving.

Write the physical expectation first

Take a hypothetical pump-bottle ad. The bottle should remain supported on the table while a finger presses the photographed pump. The pump moves in its actual direction; the bottle does not float upward or acquire another nozzle. If the source photos do not show the dispenser clearly, a whole-bottle presentation is a safer creative choice than an invented mechanism.

Before reviewing, write three anchors: where the bottle touches the table, where the finger touches the pump, and which parts are allowed to move. These anchors make a visual defect easier to describe than “the hands look strange.” Use the original product photos as authority.

Inspect five moments

  1. Approach: fingers travel toward the same pump, without passing through the bottle.
  2. Contact: the fingertip reaches the actuator before it moves.
  3. Pressure: the pump moves plausibly while the hand maintains contact.
  4. Release: the finger separates visibly rather than dissolving into the cap.
  5. Rest: the bottle and hand settle; extra fingers or accessories do not appear.

Use normal playback first, then pause or advance through the suspect region in a player that supports it. A slow inspection finds the defect; the normal-speed replay shows whether it affects the released creative. Do not let a barely visible opening distract you from an obvious broken contact later.

Record a repairable observation

An actionable review note might read, “At about six seconds, the supporting thumb overlaps the front label, then passes into the bottle as the pump moves.” This names time, affected feature and failure. A revised brief could keep the bottle on the table, limit the action to one press and use a fixed camera with the contact point visible.

That revision is a new paid generation, not an automatic correction applied to the old video. Preserve the rejected file and its note so reviewers know why the new version exists. If the demonstration still cannot preserve the mechanism, switch to a supported action such as simply presenting the bottle.

Decide whether the shot can pass

Accept a grasp only when it preserves the object’s identity and shows credible contact throughout the useful action. Stop publication when the defect changes what the product appears to do. A crop that hides the pump also hides the demonstration; it is not a meaningful solution if the pump is the selling point.

For a coordinated review, use product-drift checkpoints, tabletop scene planning and the final release gate. Each asks a different question about the same finished clip.
