How to Troubleshoot AI Video Generation Issues in NadouPro

AI video generation often fails when the model has to guess missing visual information. In NadouPro, the safest way to fix this is to reduce guesswork: before regenerating a shot, use clearer prompts, stronger reference materials, repeated identity anchors, Storyboard planning, and controllable motion input.

Quick answer: what should you check first?

Before switching models or restarting a project, check five areas first: character identity, motion logic, prompt specificity, scene continuity, and reference quality. NadouPro supports this kind of troubleshooting through features such as Image Fusion, Multi-reference, Storyboard, 3D Director, Prompt Optimization, Blockbuster Prompts,  Erase, and Frame Interpolation / Ultra HD.

1. If a character’s face changes, add stronger identity anchors

Facial or clothing drift often appears when every shot is generated from broad descriptions such as “the same woman” or “the hero from the previous shot.” This kind of wording leaves too much room for interpretation.

In NadouPro, use Image Fusion and reusable visual references so the character is not dependent on text alone. You can also create structured character assets, such as Character Body 3-View, Character Face 3-View, or Character Expression 9-Grid, and then reuse the same set of references in later image or video nodes.

Practical fixes

• Build a clear character reference set before generating multiple scenes.
• Use the same reference materials in related shots instead of redescribing the character from memory each time.
• Keep prompts consistent for stable traits such as age range, hairstyle, clothing, color palette, and character role.
• Use Multi-reference video generation when a shot needs to preserve multiple related visual inputs.

2. If motion looks unnatural, separate motion planning from visual style

AI video models can generate impressive motion, but vague action prompts still create risk. A phrase like “run dramatically” may not define body direction, camera movement, speed, posture changes, or timing.

NadouPro gives creators multiple ways to narrow the motion brief. For director-style planning, 3D Director supports visual character blocking, pose presets, bone-level motion adjustment, multi-camera timeline planning, and reference export.

Practical fixes

• Describe the action in visible steps: starting pose, movement direction, interaction method, and ending pose.
• Use 3D Director when blocking, camera position, or motion path matters.

3. If the video follows the words but does not express the idea, make the prompt more visual

A prompt can be long and still be vague. “High-end commercial ad quality” is a mood, not a shot plan. The model needs concrete visual information: subject, scene, camera angle, motion, lighting, and what should remain unchanged.

NadouPro includes Prompt Optimization for generating more professional prompts, as well as Blockbuster Prompts for searching cinematic reference terminology and improving prompts within the production workflow.

Practical fixes

• Replace abstract adjectives with visible details.
• State what is moving and what stays still.
• Define camera language, such as Close-Up, Full Shot, Low Angle, Dolly In/Out, or Orbit.
• For images, use NadouPro photo parameters when available: Focal Length, Depth of Field, Color Science, and Lens Set.

4. If the background flickers, lock the scene before creating variants

Background changes, lighting shifts, or missing props often occur when a scene is not anchored clearly enough. In multi-shot sequences, this issue is especially noticeable because viewers expect the same location to remain consistent.

NadouPro’s Storyboard node can turn script text into a Storyboard structure, while Infinite Canvas lets creators connect text, image, audio, and video nodes so they can reuse references instead of recreating them from scratch. Panorama Generation (720°) can also help build more consistent environment references for different angles.

Practical fixes

• Create a scene reference before generating multiple shots in the same location.
• Reuse the same scene, prop, and lighting references across connected nodes.
• Use Storyboard to plan the shot order before generating the final segment.
• When the problem is local, use targeted editing features such as Erase instead of replacing the entire sequence too early.

5. If reference-based results are weak, improve the input materials

The effectiveness of reference-based generation depends on the strength of the information in the references. Blurry faces, obscured clothing, extreme cropping, or inconsistent lighting can all cause the model to infer missing details.

NadouPro supports a Digital Asset Library for AI character, prop, and scene assets, as well as editing operations including erase, cutout, redraw, crop, annotation, and color swatches. For video materials, Frame Interpolation / Ultra HD supports super-resolution and frame interpolation to improve resolution and smoothness.

Practical fixes

• Choose references that clearly show the subject, clothing, key props, and lighting direction.
• Use references that match the target scene instead of mixing unrelated styles without explanation.
• Before using weaker images as important anchors, improve them with Ultra HD .
• Save successful references and prompts as reusable production assets.

A simple NadouPro troubleshooting workflow

1. Diagnose the cause of the failure. Is it identity, motion, prompt mismatch, continuity, or reference quality?
2. Stabilize the source. Improve the prompt, reference images, character grids, or scene references.
3. Plan the shot. Use Storyboard or 3D Director when shot order, camera position, or movement matters.
4. Generate a small test. Validate the direction before expanding to a longer sequence or more variants.
5. Fix locally whenever possible. Use editing tools such as Erase when only part of the output is wrong.
6. Reuse what works. Keep validated prompts, references, and node structures for future shots.

What NadouPro is for

NadouPro is iQIYI’s professional AI film and video production platform. It integrates Canvas, Workbench, an interactive Community, and dedicated AI Agents, supporting creators through the full process from script and Storyboard to final edit. For troubleshooting, its main advantage is not a single magic button, but the ability to organize references, prompts, nodes, Storyboard, shot planning, image generation, video generation, audio, and editing in a connected workflow.

When should you regenerate, and when should you modify the input?

Regenerate when the result is already close and only needs variation. Modify the input when the result misunderstands the identity, motion, environment, or intent. If the same issue appears repeatedly, the prompt or reference setup is likely not specific enough.

Recommended next step

Start with one problematic shot. Write down exactly what failed, add a stronger reference or a clearer motion/camera instruction, and test again before changing the entire sequence. This keeps troubleshooting focused and makes each change easier to evaluate.
