Distinguish Sliding, Stepping in Place, and Camera Travel
Watch the current output at normal speed, then use slow playback to locate contact faults. Check whether the body approaches a door, tile, or table edge, whether a supporting foot slides abnormally, and whether a lifted foot lands again.
A following camera, an unmarked floor, or a treadmill can change what stationary screen position means. Establish travel versus an in-place action first. Gait review concerns motion relationships rather than the presence of “no sliding” in a prompt.
Describe Travel Through Space Rather Than a Foot Checklist
| Specify | Repair |
|---|---|
| Start | Current stance, weight, and direction matching a real start frame if supplied. |
| Route | Travel between visible landmarks. |
| Support | Alternating planted support with body travel, rather than both feet pinned throughout. |
| End | Settle before the doorframe in the chosen next-shot pose. |
| Camera | A fixed frame or chosen route, not an ambiguous camera replacing subject travel. |
Do not prescribe every joint angle in every frame. The source favors ordinary whole-body actions and necessary starting facts. Walking can be one continuous action. Running, turning, handing over an object, and revealing an identity together need an actual capacity check.
Complete Original Prompt: Walk to the Doorframe
Original purpose: show Liu Ning travel from inside the room to a closed door. The author chooses text-to-video, with no reference image or generated result. Six seconds is an illustrative proposed window: match the actual execution mode before submission and review completion afterward.
Copyable prompt:
Liu Ning wears a gray sweater and dark trousers on the tiled floor of a pale workshop. A closed wooden door is two steps ahead. Fixed full-body framing includes the soles’ contact area, tile seams, and doorframe in soft side-window light. She starts with both feet on the floor, weight toward the left, arms resting at her sides. She first looks at the door, then walks two ordinary steps toward it, alternating planted support as her body advances. She settles before the frame, facing the closed door with arms still at her sides. The camera stays fixed throughout so the start, footfalls, and arrival remain visible. Sound consists of footsteps and room ambience, with no dialogue, voiceover, or music. Generate no non-diegetic subtitles, captions, or dialogue text overlays at any point.
Two steps and this endpoint are chosen for the example, not guaranteed precise model controls. Check foot contact, body travel, actual arrival, and continuity of the door and hands. An end frame at the door does not excuse sliding through the intervening motion.
Check the Reference Start and Any Reframing
With a real start frame, check cropped feet, readable stance, floor, and destination. Unseen conditions cannot be credited to the image. Repair the start through storyboard and image work if needed. Text or a filename is not proof of observation.
For an upper-body close-up, account for arrival at the door. Where feet carry no story information, the author may use another shot to cover travel. Footsteps, a limp, or crossing an obstacle cannot disappear if they carry the scene. Update the storyboard, prompts, and neighbors after changed boundaries or cuts.
Review the Whole Interval
Check body travel first, then support, speed, and camera compatibility, followed by sound and next-shot continuity. Slow playback locates faults; normal playback evaluates the current viewing result.
If it fails, remove irrelevant parallel activity or clarify the route. A changed duty requires a complete alternative plan. Review the actual new output after a prompt change rather than combining the faulty old clip with a good ending still. No generated or gait-tested result exists here.
FAQ
Is “walk naturally, no sliding” enough?
It still leaves weight, travel, floor anchors, and the end position unspecified. Establish those conditions and inspect actual motion; prohibitions do not guarantee correct contact.
Can I crop above the waist?
The author may reframe while covering required travel or gait information. If feet carry the story, hiding them drops a duty. A crop does not prove that the original gait is repaired.
Do it with the skill
Use $short-drama-video-prompts on the named walking shot with its storyboard, boundaries, actual references, and the slipping location. Check support changes, body route, camera, and end landmark while retaining duration, sound, and the next shot’s state. Propose a complete prompt; if framing, cuts, or boundaries change, account for original duties before updating the storyboard.
