A reference image is not just something you upload before generation. In OmniVideo, it is the visual contract for the draft: the person, product, logo, layout, or mood the motion should protect.
When an image-to-video result fails, the problem is often not that the prompt was too short. The problem is that the source frame, motion request, and review standard were all trying to do different jobs.

Start with the visual contract
Before generation, name what must remain recognizable. For a person, that may be face shape, hairstyle, outfit, posture, and expression range. For a product, it may be silhouette, label position, material, hero detail, and scale. For a layout, it may be the main composition and hierarchy.
Write that contract in plain language. A good motion draft is allowed to move, but it should not quietly replace the asset you approved.
Pick one anchor frame
Use the cleanest image as the main anchor. It should have a clear subject, readable edges, stable lighting, and enough room around the subject for motion. If the frame is cropped too tightly or already distorted, the model has less reliable information to protect.
Extra references can help only when they agree with the main frame. If one image shows a straight-on face and another shows a different hairstyle, the model may average the conflict and create drift.
Give the motion a budget
The motion budget is the amount of change you are asking the clip to absorb. A slow push-in, small head turn, gentle product rotation, or light shift is a small budget. Running, spinning, camera orbit, outfit movement, new background action, and dramatic expression change in one prompt is a large budget.
Start small. If the first draft holds the identity, you can add more movement in the next test.
Prompt pattern for stable motion
Use the uploaded image as the visual anchor. Preserve [face/product/logo/layout detail]. Add one restrained movement: [movement]. Camera: [camera behavior]. Keep [critical details] stable. Review focus: does the subject remain recognizable after motion?This pattern keeps the source frame in charge and makes the review standard explicit.
Review in passes
Do not judge the whole clip at once. Watch it in passes:
- Identity pass: face, product shape, logo, outfit, or layout.
- Motion pass: does the requested movement happen clearly?
- Background pass: does the environment stay coherent?
- Channel pass: does the frame still work for the intended placement?
If identity fails, reduce motion before changing style. If motion fails but identity holds, revise the action or camera note.
Final takeaway
Stable image-to-video work is a control problem. OmniVideo is strongest when the source frame has a clear job, the prompt gives one motion instruction, and the review asks whether the approved visual survived the movement.
