How to fix common AI video problems: hands, text, warping
Practical fixes for AI video artifacts: warped hands, broken text, melting objects, face drift and flicker, with before and after prompts for each problem.
The short answer
Most AI video artifacts come from asking the model to track too many small moving parts at once. Fix them in this order: simplify the shot so the problem is less likely, give the model a better first frame, shorten the clip, and if a good take has one bad spot, edit that spot instead of regenerating everything.
Each common problem has a known cause. Once you know it, you can design around it.
Hands and fingers
Cause: hands have many small parts that overlap, bend and hide each other, and they often move fast.
- Give hands a simple job: holding a cup, resting on a table, in pockets.
- Avoid finger counting, interlocked fingers, typing close-ups and fast gestures.
- Frame hands larger if they matter, or keep them out of frame if they do not.
- Start from a still where the hands are already correct.
Before: "A woman talks excitedly with lots of hand gestures while explaining a recipe." After: "A woman talks warmly to camera while resting both hands on a wooden cutting board, she lifts one hand to point at the bowl beside her once."
Text, signs and logos
Cause: video models draw letters as shapes, not as language, and the shapes change from frame to frame.
- Do not ask for readable text in the scene. Keep signs out of focus or turned away.
- Add titles, captions, prices and labels in the edit.
- For product labels, start from a real photo and keep the label still.
- Use motion graphics for anything where every word matters. ClickPop's Faceless Studio draws diagrams, charts and kinetic type in code, so every word and number is exact.
Before: "A neon sign above a bar that says OPEN LATE in pink letters, camera pushes in." After: "A glowing pink neon sign above a bar door, shallow depth of field so the sign is a soft blur of pink light, camera pushes in toward the door." Add the words OPEN LATE as a caption or a tracked title in the edit if the viewer needs to read them.
Warping, melting and extra limbs
Cause: the model is inventing large changes, such as fast motion, objects passing behind each other, crowds or bodies twisting.
- One main action per shot.
- Slow the action and the camera.
- Reduce the number of people and objects that move.
- Shorten the clip. Problems grow over time.
- Avoid bodies crossing each other, such as dancing couples or tangled sports action, or frame them wider so small errors do not show.
Before: "Two people dancing salsa fast in a crowded club, spinning, camera orbiting." After: "Medium wide shot of a couple dancing slowly in a dim empty club, she turns once under his arm, camera locked off, warm light."
Faces that drift
Cause: no fixed reference for the face, big head turns, or long clips.
- Use a character with reference images. In ClickPop, the Characters studio sends the same reference photos with every video.
- Keep head turns small and slow.
- Use medium close-ups rather than extreme close-ups or distant wides.
- Cut to a new angle instead of extending one long shot.
- Keep lighting even on the face. Hard moving shadows across the face make features appear to change.
Before: "A man walks through a crowded market, turning to look at stalls on both sides, then spins around when someone calls his name, close-up." After: "Medium shot, the man from the reference walks slowly through a market, glancing once to his left at a fruit stall. Camera follows at shoulder height." Shoot the reaction to his name as a separate medium close-up.
Flicker, crawling backgrounds and physics
- Flicker in light or color: describe one stable light source and avoid busy patterned surfaces.
- Crawling textures in backgrounds: grass, brick and fine patterns shimmer. Use shallow depth of field so the background is soft.
- Odd physics, such as liquids pouring upward or objects floating: describe the cause and effect in order, "she tilts the jug and water pours down into the glass".
- Objects appearing or vanishing: name every important object in the prompt and keep them few.
Fix one spot instead of regenerating
If a take is good except for one problem, edit it. In ClickPop, Edit Video can restyle, relight or change what is in a clip. Runway Aleph 2 and FLUX Video Edit are among the models in ClickPop that edit existing footage. Describe only the change: "Replace the sign text with a blank wooden board", "Remove the extra cup on the left of the table".
Other quick fixes in the edit: trim the frames where the problem appears, cut away to an insert shot, or crop slightly if the problem sits at the frame edge.
Check problems before upscaling. Upscaling makes detail sharper, including the errors.
A pre-render checklist
- One subject, one action, one camera move?
- Hands simple or out of frame?
- No readable text in the scene?
- Character references attached?
- Clip length suited to the action, and not longer?
- Drafting on a cheaper model before the final? Failed renders are refunded, but takes you simply do not like are not failed renders, so test cheaply.
Questions
Why does AI video mess up hands?
Hands have many small overlapping parts that move quickly, which is hard for models to track. Give hands simple actions, frame them clearly or keep them out of shot, and start from a still where they look right.
How do I get readable text in AI video?
Do not render it in the scene. Add text in the edit, or use motion graphics drawn in code, such as ClickPop's Faceless Studio, where every word and number is exact.
Should I regenerate or edit a flawed AI clip?
If the take is good except for one spot, edit it with a video editing model or trim around it. Regenerate when the motion or composition itself is wrong.
