Clarify the business value of motion consistency during project initiation
Before launching an AIGC commercial project, brands must clarify the core role of character motion in the communication chain. In traditional live-action videos, actor performances have physical continuity, whereas generative imagery often faces risks of inter-frame flickering or limb distortion. If core selling points rely on precise hand operations or complex facial micro-expressions, adopting a purely generative approach may increase post-production repair costs. Marketing heads should assess the target audience's tolerance threshold for visual realism. For brand narratives emphasizing emotional resonance, the natural fluidity of motion directly impacts trust building. If motion serves only as a background atmospheric element, standards can be relaxed to gain creative efficiency. The project initiation document must include a prioritized list of motions, distinguishing key actions from non-critical dynamics, to provide a basis for subsequent technology selection.
Prepare a highly detailed reference material library
During pre-production, the production team cannot rely solely on text scripts; they must build a visual motion reference library. Brands need to collect real video clips highly similar to the expected motions, covering starting poses, movement trajectories, and ending freezes. These reference materials will serve as foundational anchors for prompt engineering, helping algorithms understand physical laws. Lack of specific visual references leads to logical breaks in generated results, such as foot sliding during walking or finger penetration when grabbing objects. Reference materials should cover different lighting conditions and shooting angles to maintain motion skeleton stability during later style transfer. Meanwhile, copyright elements in reference materials that cannot be replicated must be marked to ensure the final film does not infringe on third-party rights. This step determines the baseline quality of generated content and is a key defense line for controlling randomness.
Break down motion units and set keyframe constraints
In the production execution phase, directors and AI artists need to break down continuous motions into independent units. Each unit corresponds to a stable generation window to avoid cumulative errors from long takes. For complex interactions, such as character-product contact, a layered generation strategy is recommended. First lock the main character motion, then generate product dynamics separately, and finally perform spatial matching during compositing. Keyframe constraints are the core method for ensuring motion coherence. The team must mark pose nodes that must remain unchanged on the timeline, forcing the algorithm to interpolate between these nodes. If distortion appears in intermediate frames, adjust prompt weights or switch ControlNet models immediately rather than relying on post-production fixes. This stage requires repeated testing of samples to confirm that motion rhythm aligns with brand tone, avoiding information loss from excessive speed or viewer fatigue from slowness.
Scene setup and personnel collaboration standards
Although AIGC production does not require physical studios, rigorous planning is still needed for virtual scene logic construction. Art directors must define environmental lighting consistency to ensure character motions match background perspective relationships. If multi-character interactions are involved, pre-set spatial distances and sightlines between characters to prevent clipping or gaze misalignment during generation. Regarding personnel arrangement, designate dedicated prompt engineers for precise translation of motion descriptions and technical artists for fine-tuning ControlNet parameters. Both parties must sync generated samples daily to calibrate motion amplitude and force expression. Any vague descriptions of motion force, such as 'pick up gently,' must be converted into specific physical parameters or reference video links to reduce communication ambiguity. The core of team collaboration lies in translating abstract creativity into quantifiable technical parameters.
Physical logic validation in post-production repair
After the initial draft is generated, the post-production team must intervene for physical logic validation. Focus on checking gravity representation, light-shadow following, and occlusion relationships. Common errors include hair floating against gravity, shadow directions mismatching light sources, or objects passing through bodies. Fixing these issues requires combining traditional digital compositing techniques, such as using rotoscoping to isolate abnormal areas, regenerating local patches, and blending them. Sound design must also align with motion rhythm to enhance realism. If motion amplitude is large, add motion blur to mask generation artifacts. Brands should focus on the match between motion and product functionality at this stage, ensuring the demonstration process conforms to scientific common sense. Any motion violating physical laws will weaken professional image, unless it is a deliberately pursued surrealist art style. During acceptance, review high-speed motion segments frame by frame to ensure no obvious artifacts or tearing.
Establish a multi-dimensional final delivery acceptance checklist
Delivery acceptance should not rely solely on subjective feelings but must verify items against a preset checklist. First, check motion continuity to confirm no abrupt jumps or shape mutations. Second, check interaction realism to verify whether contact points between characters, props, and environments are reasonable. Third, check facial expression stability to ensure lip-sync with voiceover and coherent emotional expression. Fourth, check background dynamics to avoid illogical flow or deformation of background elements. Fifth, check resolution and noise levels to ensure details remain clear and usable when enlarged. For each non-compliant item, specify the exact timestamp and problem description; when returning for revision, limit the repair scope to avoid unintended side effects. Acceptance records should form a complete process as data assets for optimizing future projects. If core motion defects persist after multiple revisions, trigger the backup plan mechanism.
Identify scenarios unsuitable for AIGC motion generation
Not all brand videos are suitable for generating character motions via AIGC. Product demonstrations requiring high precision, such as operating precision instruments or medical surgical steps, have extremely low error tolerance and should use live-action or 3D animation. Projects involving specific celebrity likeness rights require explicit authorization and dedicated training models to avoid legal risks. Scenes needing precise reproduction of historical events or true documentaries are unsuitable for random generative technologies due to high factual accuracy requirements. Additionally, if budgets are limited and timelines extremely short, AIGC iteration debugging costs may exceed traditional production. Brands must rationally assess technical boundaries to avoid sacrificing content accuracy for new technology. In projects with high uncertainty, retaining live-action backup shots is a wise risk hedging strategy.
Prudent recommendations for next-step collaboration
After establishing the above standards, brands can engage in deep communication with teams capable of AIGC video production. ONCE provides services including corporate promotional videos, brand films, and AIGC video production, assisting clients in clarifying communication goals and core selling points. It is recommended that both parties refine the motion reference library and acceptance metrics based on actual case materials. Validate workflow feasibility through small-scale pilots before gradually expanding application scope. Stay attentive to technological iterations and regularly update production specifications to ensure brand content achieves balance between technology and art. Do not blindly pursue full automation from pre-production to delivery; human review and creative intervention remain necessary steps for ensuring quality.
