Build a reusable visual reference set, plan framing and camera movement shot by shot, generate short clips, then review and edit for continuity. Current tools can use images to guide a subject’s appearance, but that is not the same as importing and precisely animating an editable 3D model.
Can you use your own 3D models in AI-generated films?
Sometimes you can bring assets into a filmmaking workflow, but the documented capabilities here do not establish that Flow or Veo accepts native 3D model files such as editable mesh assets as direct video-generation inputs. Google describes Flow as supporting creator-supplied assets and reusable image ingredients; Veo documents reference-image guidance. Those are useful ways to carry a model’s appearance into generated footage, but they do not guarantee that the video reproduces the model’s exact geometry, rig, materials, or pose. Google’s Flow announcement and Veo’s developer documentation describe image- and asset-oriented workflows.

If your source is an editable 3D scene, render reference views first: a neutral character portrait, a full-body view, distinctive costume or prop details, and environment angles. Treat these images as visual guides, not as a substitute for a 3D pipeline that guarantees exact model control.

How do I make AI characters look the same in every scene?
Create a compact asset bible before generating shots. It gives you a consistent reference set and a fixed description to reuse, reducing the number of visual decisions you improvise from clip to clip.

Build the reference set
- Character: Save clear views of the face, full-body silhouette, clothing, colors, and distinctive features. Add an expression or pose reference only when it matters to a shot.
- Props: Capture recognizable shapes, markings, scale cues, and how an important object is held or used.
- Locations: Keep a wide view and a few useful angles of each recurring environment. Note fixed landmarks, entrances, and the direction of important light.
- Film language: Record the palette, contrast, lighting mood, and visual style you want to carry through the project.
In the Veo 3.1 API documentation checked on October 4, 2026, Google specifies up to three reference images for a single person, character, or product to guide video output. Flow also describes reusing ingredients across clips and scenes. Use whichever reference options are available in your chosen tool, and keep character descriptions stable across prompts. These features guide appearance; they are not promises of identical mesh geometry or frame-to-frame continuity. Veo API documentation · Flow overview.
How should I plan shots for an AI film?
Write a shot list before prompting. Describe the audience’s view, not just what the subject is. For every shot, record the action, composition, camera movement, style, light, location, and any sound or dialogue intention.
Rank #2
| Shot note | What to specify | Example |
|---|---|---|
| Subject and action | Who or what is visible, and what changes during the shot? | The courier places a brass key on the table. |
| Framing and position | Distance, angle, and where the subject sits in frame. | Eye-level medium shot; courier on the left, key in foreground. |
| Camera motion | Whether the camera moves, and how. | Slow dolly toward the key. |
| Style and lighting | Visual treatment, palette, light direction, and mood. | Muted amber palette; window light from camera right. |
| Location and continuity | Set, landmarks, screen direction, and object state. | Same workshop; key remains on the table after placement. |
| Sound intention | Dialogue, ambience, or effects needed for the edit. | Quiet room tone and a soft metallic tap. |
Favor one clear action and one camera idea per short shot. If a prompt asks for several major actions, a location change, and a complex camera move at once, it becomes harder to tell whether the output missed the performance, composition, or transition you intended.
How do I control the camera in AI video?
State the shot size or viewpoint and the movement in plain language, then keep the subject’s action separate. Google’s Veo prompt guidance includes aerial, eye-level, and top-down viewpoints, as well as dolly moves. For example: “Eye-level medium shot of the courier setting down the key; slow dolly in; warm window light from the right.” This is a direction to the generator, not a guarantee that it will follow a precise path. Google’s Veo prompt guidance.
For a sequence, map camera choices to story purpose. A wide establishing view can locate an audience; a close shot can emphasize a decision or object; a moving shot can reveal a new detail. Avoid changing framing or direction arbitrarily between adjacent clips, especially when the edit depends on a subject moving across the frame.
How do you generate and refine the clips?
- Choose the clip’s job. Decide what new story information this shot delivers and which reference ingredients it needs.
- Write the prompt from the shot list. Include the subject and action, framing, camera movement, style, lighting, and location. Add sound or dialogue intention if the tool supports it.
- Generate a short shot. Review the result against the intended action and composition rather than judging only whether it looks striking.
- Revise the failed element. If identity drifted, strengthen or change the reference images and stable character description. If framing or motion is wrong, simplify the camera direction. If the action is muddled, reduce it to one main event.
- Keep usable versions. Save the prompt and selected output with the shot identifier so you can compare alternatives and maintain the same visual decisions later.
As documented on October 4, 2026, Veo 3.1 generates eight-second clips with native audio; the API lists 720p, 1080p, and 4K output depending on variant. Veo 3.1 Lite does not offer 4K, and Google says 4K takes longer and costs more. These are live product specifications, not fixed guarantees; check the current API documentation for the variant and access route you plan to use. Veo video generation documentation.

How do you keep scenes coherent when editing?
Generated clips are not deterministic 3D cinematography. OpenAI’s Sora research page identifies remaining challenges with complex-scene physics, spatial details such as left and right, and precise camera trajectories. Google’s features such as scene building, scene extension, and first/last-frame transitions can help connect material, but they do not guarantee seamless continuity. Check every join in the edit. OpenAI’s Sora research page · Google DeepMind’s Veo overview.
- Identity: Does the character retain recognizable features, costume, and proportions?
- Screen direction: Does movement continue in a plausible direction across the cut?
- Scale and space: Are people, props, and landmarks in consistent relative positions?
- Light and color: Do adjacent clips plausibly belong to the same time, place, and visual treatment?
- Object state: Does a prop remain where the action left it, and is it held or used consistently?
- Transition: Does the next clip begin in a way that supports the preceding action rather than appearing to restart it?
When a cut fails, revise the shot that breaks continuity or edit around the mismatch. Do not assume a feature name such as “scene extension” means the model will preserve every detail you need.
What should you check when choosing an AI filmmaking tool?
- References: Can it accept images or reusable ingredients for the character, product, or environment you need?
- Direction: Are framing and camera movement expressed in a way that suits your shot list?
- Scene connections: Does it support extension, first/last frames, or scene building that may help your edit?
- Audio: Do you need generated sound or dialogue, and does the selected generation mode provide it?
- Output: Confirm available duration and resolution for the exact model variant; higher resolution may take longer or cost more.
- Access and iteration: Check current regional availability, plan or API access, quotas, and the cost of generating alternatives.
- Asset rights: Verify the service’s current terms for uploaded assets and generated outputs before using them in a release. Those rights are separate from technical support for references.
Google introduced Flow on May 20, 2025 as a filmmaking tool designed for Veo, Imagen, and Gemini, with asset management, scene building, camera controls, and reusable ingredients. Its original US subscriber availability announcement is historical, not a current access map; confirm current access and plan details directly. Google later reported more than 275 million videos generated in Flow during the five months after introduction, a vendor-reported usage figure rather than an independent measure of quality. Flow launch announcement · Google’s Flow update.
Google DeepMind also publishes Veo benchmark comparisons, including results dated October 2025. The page describes 1,003 text-to-video prompts for stated preference, alignment, and visual-quality measures; 355 image/text pairs for image-to-video comparisons; and 527 prompts for text-to-video-and-audio comparisons. These are benchmark sample counts and Google-reported results under specified conditions—not proof that one model will be best for every project. Google DeepMind’s Veo benchmark page.
Availability can change: OpenAI’s Sora research page states that the Sora product is no longer available as of April 26, 2026, so that page should not be taken as evidence of a currently accessible product. OpenAI Sora.
