Checklist

What makes an AI product video look real: a checklist

Updated September 23, 2026

Viewers decide in a second whether a video feels like a post or a render. Most AI videos that feel fake fail on the same few details. This checklist is the one to run on every AI product video before it goes live. It is also, for the record, the reason realistic does not mean deceptive: a video can look natural and still carry TikTok's AI label, which is exactly what TikTok asks for.

How to use it: watch each video twice. First at full speed, the way a viewer would, and note anything that made you hesitate. Then scrub through slowly, stopping at every moment of contact and every cut. Most problems show up in the second pass, in less than a minute per video.

1. Hands

Hands are the classic giveaway. They move a lot, overlap other objects, and are hard for video models to keep consistent.

• Five fingers on each hand, in every frame, including when fingers overlap.
• Fingers that wrap around what they hold instead of passing through it.
• Hands that stay the same size, skin tone and shape as they move.
• No hand merging into the product, the phone or the body.

Watch the moments of contact closely: picking up a shoe, adjusting a hem, holding the phone. Those are where hands break.

2. The phone in a mirror selfie

The mirror selfie is one of the most common TikTok Shop fashion formats, and the phone in it is a detail viewers notice without knowing they noticed. Check that:

• The phone is actually in the hand, not floating in front of it.
• It is the right way round: the camera faces the mirror, the screen faces the creator.
• It keeps its shape. No bending, melting or changing size between frames.
• It stays one phone. A second phone appearing, or the phone vanishing mid-video, ends the illusion.
• The reflection makes sense: what you see in the mirror matches where the person stands.

FlowFits runs a dedicated phone check on every video for this reason.

3. The product matches the listing

This is the one that matters most, because it is not only about realism. A video that shows a different product from the one being sold misleads buyers. Compare the video with the product photo on each of these:

FlowFits checks every video against the product photo before delivery, covering colour, print, logo text and cut. A video that drifts is re-rendered or held, never delivered. You should still take a final look, because what you post is your responsibility.

4. Lighting that agrees with the room

Lighting is subtle, and wrong lighting is why some AI videos feel off without an obvious mistake.

• One light story. If the window is on the left, the shadows fall to the right, on the person, the product and the floor.
• The product belongs in the light. A garment that looks studio-lit in a dim bedroom looks pasted in.
• Reflections agree. In a mirror, the light on the reflected person matches the room.
• Skin looks like skin. Not waxy, not glowing, not smoothed into plastic.
• Colour survives the light. Warm room light should warm the scene, not change the product's actual colour. If it does, the product check should catch it.

5. Face, body, motion and cuts

The last group covers everything that should stay constant while the video moves:

• The face stays the same person from start to finish, and across every video on the account. A saved creator per account helps here; FlowFits keeps one creator for every video an account posts.
• Anatomy holds. No extra limbs, merged arms, bending joints or feet sinking into the floor. FlowFits runs an anatomy check on every video.
• Movement has weight. Fabric swings and settles; hair moves with the head; a step lands.
• The background behaves. Furniture does not drift, text on walls does not morph, doors stay doors.
• Cuts are clean. No jump, flash or glitch between shots. FlowFits runs a cut check for this.
• The body position makes sense. A person shown sitting has something to sit on. A standing pose does not float.

What to do when a video fails a check

1. 01

   Fix it at the first frame

   Most problems are cheapest to catch before any video renders. On FlowFits you approve the first frame and can change anything in plain words.

2. 02

   Swap the photo

   If the product keeps drifting, the photo is often the cause: filtered, cropped or on a busy background. Use a clearer one.

3. 03

   Render again

   A new render often fixes a one-off glitch with a hand or a cut.

4. 04

   Drop it

   If a video is nearly right but not quite, do not post it. One bad video costs more trust than one missing video.

Realistic, and labeled

Looking real is about quality, not about hiding that a video is AI. TikTok requires creators to label AI-generated content that contains realistic images, audio or video, and says the label does not affect distribution as long as the video follows its Community Guidelines. Turn it on for every AI video, and never let an AI creator claim to have used the product: the FTC's rule on consumer reviews and testimonials covers reviews that claim to come from someone who does not exist, such as AI-generated fake reviews.
