What Is a Motion Reference in Multi-Person Video Synthesis?
A motion reference is a video used to communicate movement to a compatible generation system. It is different from an identity photograph, which shows who should appear, and from a finished output, which shows what the system actually produced. Not every video generator accepts motion references, and support for multiple people varies.
Runway Act-Two describes a workflow with a driving performance and a character reference. Its instructions apply to that product. They do not establish how NEON DUO's provider works, or prove that any particular two-person reference will succeed.
Four Practical Reference Checks
- Framing: If you need to reproduce footwork, choose footage where you can actually see the feet. Watch wide arm movements as well as the opening pose. A full-body view is a useful selection preference, not a universal input rule for every model.
- Occlusion: This means one subject blocks another. Mark moments where a face or limb disappears and check what becomes visible afterward. There is no verified number of seconds that guarantees safe overlap.
- Camera continuity: A continuous view helps you follow the routine. Cuts, shake and zooms can obscure whether apparent movement comes from the dancer or camera. Check the target system's documented requirements rather than assuming all cuts cause a particular internal failure.
- Separate paths: Follow each performer from beginning to end. Note entrances, crossings and exits. Screen position can change while the intended role stays the same.
Motion Reference Evaluation Checklist
Before selecting a dance sequence to drive your animation, verify candidate footage against this diagnostic checklist:
- Continuous Single Take: Prefer a continuous view when your goal is to inspect one complete routine.
- Unbroken Full-Body Framing: Check whether the body parts relevant to your intended action remain visible.
- Controlled Physical Occlusion: Dancers avoid prolonged front-to-back overlaps where one performer is completely hidden.
- Readable Movement Paths: The choreography maintains distinct spatial corridors between lead and supporting actions.
- Stable Perspective: The footage is filmed on a steady tripod or smooth stabilizer without handheld jitter or rapid focal zooms.
- Clean Background and Lighting: Check whether lighting, background objects or bystanders make either performer difficult to follow.
Worked Hypothetical Example: Evaluating Candidate Footage
To see how these criteria apply in practice, consider this illustrative evaluation of two hypothetical 15-second candidate routines:
- Candidate A, hypothetical: Handheld footage includes two cuts and a moment when one performer is hidden behind the other. You cannot tell whether the pose after the cut continues the same movement. Record the missing information and look for an uncut version before selecting it.
- Candidate B, hypothetical: A stationary wide shot shows both people throughout a crossing. You can trace who enters each side and how the footwork finishes. It is easier to review for this task, but that does not prove a generator will reproduce it correctly.
The decision is based on observable information, not an invented quality score. If neither clip shows the movement you need, seek a different authorized source rather than treating a guessed motion as documented choreography.
How Pre-Curated Templates Work on NEON DUO
Understanding platform boundaries helps set realistic expectations for your dance projects.
On NEON DUO, animations rely on pre-curated motion templates. The public interface does not offer arbitrary video reference uploads or custom prompt boxes. The scene styles use the same bound choreography reference. Changing a scene style does not select a new routine; public reference playback is not evidence of generated output quality.
- Photo Requirements: Users supply two separate photos of consenting adults in JPG, PNG, or WebP format up to 10 MB each. While our photo preparation guide explains how to format compatible inputs, source clarity gives you a better basis for comparing the intended appearance.
- Output Standards: Outputs are planned as 15-second H.264 MP4 video files in 480p or 720p resolution, available in portrait (9:16) or landscape (16:9) formats.
- Choreographic Movement: As outlined in our two-person dance setup guide, assigned lead and supporting roles govern interaction pathways rather than locked screen positions. If a routine includes a crossover, dancers naturally exchange sides.
- Access: User photos and generated results remain private to the authenticated owner. Public reference clips are separate demonstration material.

Frequently asked questions
Can I upload my own custom dance video as a motion reference on NEON DUO?
No. The public form uses a bound reference and does not offer arbitrary motion-video uploads. This is an interface limitation, not proof that the reference has passed live generation acceptance.
Why do commercial music videos fail as dance motion references?
Some contain cuts and close-ups that hide parts of a routine. Others include continuous wide shots. Evaluate the actual segment and the target model requirements; do not reject or approve a clip solely because it is a commercial music video. You also need appropriate permission to use the footage.
What happens when dancers briefly cross paths during a turn?
A crossing can be part of the intended dance. Inspect both performers before and after it, and note any hidden action. Its duration alone cannot tell you whether a particular model will maintain identity or motion.
Does choosing a stable motion template compensate for blurry photos?
No. Motion references establish choreography, but source photos define character appearance. A stable reference cannot repair facial distortion or indistinct silhouettes caused by low-resolution, shadowed, or cluttered source images. High-contrast source photos remain essential.
Selecting a readable reference helps you define and evaluate the intended movement; actual generation quality still needs separate verification.
