Skeleton vs Skin: How to Review AI Video Shots Against the Plan, Not the Mood

Introduction

The clip comes back. You watch it once, feel something is off, and hit regenerate. Three rerolls later you have four clips that each feel off in a different way and no idea which one was closest. The problem was never the model; it was that "feels off" is not a review. You were comparing the clip to a mood in your head instead of to the plan you wrote.

Every generated shot has two layers. The skeleton is what the plan specified: where the camera is, which way the character moves, what is in front of what, when things happen, who the character is. The skin is everything the model filled in: the exact light, the texture of the wall, the extras in the background. This guide shows how to review AI video shots in two passes — skeleton against the plan, then skin — so you reject the right things and stop rerolling the wrong ones.

The five skeleton items

These come from the shot card and its references. Each is a yes or no.

1. Camera direction and move. Does the camera do the one thing the card says — push, track left to right, hold — and end where the card said?
2. Character route. Does the character start where the card says, move the direction it says, and stop where it says?
3. Layering. Is the foreground object in front, the character in the middle, the background behind, as the layout says?
4. Timing. Does the action land within the shot's length? Does the beat happen, or does the clip end before it?
5. Identity. Is it the right character — the asset's face, hair, outfit — and the right location?

If all five pass, the shot is structurally done. If one fails, that is the fix, and it is usually one line on the shot card.

The skin: what you accept by default

• Exact color temperature of the light, as long as the direction matches the scene.
• Wall texture, floor detail, the pattern on a curtain.
• Background extras, passing cars, birds.
• Cloth movement, hair movement, small secondary motion.
• Reflections and particles.

Skin varies between generations and between shots, and audiences do not track it at the cut. Reviewing it before the skeleton passes wastes rerolls on things nobody will see. Reviewing it after the skeleton passes is a five-second check for anything that breaks the story — a modern car in a period street, a second character who was not supposed to exist.

Rules for the two-pass review

• Skeleton before skin, always. Do not let a beautiful skin distract you from a flipped camera.
• Compare to the card, not to memory. Open the shot card and its reference still next to the clip. The plan is written down; use it.
• One failed item means one fix. A flipped direction is a direction sentence, not a new prompt. Change the one line and regenerate once.
• Two or more failed items means the card is unclear. Rewrite the card before regenerating; do not reroll and hope.
• Skin failures that matter are story failures. Wrong era, wrong weather for the scene, an object that contradicts a later shot. Everything else passes.

For how many passes a whole episode needs and what to sample, the review process guide covers the schedule. This article is what to look at inside each pass.

How to run the review, step by step

1. Open the shot card and the clip side by side. If the card has a reference still, put it next to the first frame.
2. Check the five skeleton items in order and write the result as five words: pass, pass, fail, pass, pass.
3. If everything passes, mark the shot done for structure and move to skin.
4. If one item fails, find the sentence on the card that should have prevented it. Missing? Add it. Present but vague? Make it specific. Regenerate once.
5. If two or more fail, rewrite the card: camera in one sentence, action in one sentence, @ references for identity, reference still attached. Then regenerate.
6. Skin pass on structurally done shots only. Watch once for story-breaking detail. Accept the rest.
7. When a skin issue really matters, fix the layer, not the shot. Wrong light direction is a light sentence. Wrong outfit is a character asset reference. Do not reroll the whole shot for one layer.
8. Batch the regenerations. Collect the fixed cards and run them together through the AI Chat Panel, then review the batch the same way.

Example 1: A skeleton failure with a one-line fix

Shot card: Tracking shot, camera behind @Kaito at shoulder height, following left to right along the ridge path. He passes the stone pillar on his right. Ends as he reaches the statue.
Review: camera pass, route FAIL (passed the pillar on his left), layering pass, timing pass, identity pass.
Fix: add "the pillar crosses the foreground on the right side of frame." Regenerate once.

Example 2: A skin variation that passes

Shot card: Medium shot, camera static at eye level, @Mira at the café window reading. Late morning light from the right.
Review: all five skeleton items pass.
Skin: the light is cooler than the previous shot, the curtain pattern is different, a bicycle passes outside.
Decision: pass. Light direction matches, nothing contradicts the scene. Color can be evened in Edit if it bothers you at the cut.

Example 3: Two failures, rewrite the card

Original card: @Ren walks up to the vendor and they talk, camera follows and then shows the vendor's reaction, busy street.
Review: camera FAIL (swung to the front), route FAIL (Ren approached from the wrong side), layering pass, timing FAIL (no reaction in the clip).
Rewrite: split into two shots. Shot A: over-the-shoulder behind @Ren, tracking at walking pace, he stops two steps from @Vendor Marcus. Shot B: reverse, static, Marcus reacts.

The most common review mistakes

• Rerolling on skin. The shot was structurally right and got thrown away for a color. Check the skeleton first and it would have passed.
• Reviewing from memory. The plan said left to right; you remembered right to left. Open the card.
• Fixing three things at once. Three changes, one regeneration, no idea which change worked. One fix per regeneration.
• Treating identity as skin. A slightly different face is a skeleton failure, not a detail. Check the asset references.
• Skipping the skin pass entirely. The modern car in the medieval street made it to the final cut. Five seconds would have caught it.

FAQ

What if the skeleton passes but the shot is boring? That is a planning note, not a review failure. Write a better card — a stronger action, a more committed camera — and treat it as a new shot, not a reroll.

Can timing be fixed in Edit instead of regenerating? Often. If the action lands but the clip runs long, trim. If the action does not land at all, regenerate with a shorter, more specific action.

How strict should identity be? Strict. If a viewer paused on the frame, would they say it is the same character as the last shot? If not, it fails. Check the asset's Main image and references before changing anything on the card.

Does this work for stills as well as video? Yes, and it is faster. Review the still's skeleton before generating video; a failed still is a failed video waiting to cost more.

Next step

Take the last shot you rerolled three times and review the first version against its card with the five skeleton items. If it passed, you have already spent three generations on skin. Open the project in ArcLoop, fix the one line that actually failed, and regenerate once.
