Lock the still before motion control

Lock the still before you run motion control. Motion control copies the movement in a driving video onto a subject you supply. Two files go in: a performance clip, and a character (or product) still. The order of operations is still first, then the driving clip, then the row. A paragraph in the prompt cannot replace either file. A driving clip on a still you have not approved is how you spend a motion-control credit on the wrong person dancing correctly.

This is not the definition of the mode. The definition is: driving clip in, pose out. This page is the weekly radio: do not open the motion-control row until the still would pass a freeze-frame audit.

Order of operations

1. Lock the still. Face, wardrobe, product, framing. Full body if the motion uses a full body. A tight headshot against a full-body drive is the most common way this looks wrong. Iterate at image prices until someone can point at a frame and say “that one.”
2. Lock the driving clip. The walk, the dance, the turn, the gesture. Head, shoulders, and torso visible if the model is Kling-shaped. Subject fully in frame. You have the rights. Length of the drive is length of the output.
3. Match framing. The still should be composed like the clip. Do not drive a wide performance onto a cropped beauty still and hope the model invents legs.
4. Then pick the row. Kling Video V3 Pro Motion Control is the published Pro row: motion-control category, image required, 1080p, 17 credits, audio off. Standard exists as a sibling. DreamActor-class rows may not even expose a useful text field. The movement is the video file.

Prompt, if the row allows one, is wardrobe, backdrop, mood — 0–2500 characters on Kling V3 Motion Control, optional. It is not choreography. If you write a camera essay into that box, you are arguing with a file.

Audio is off on the Pro motion-control card. You will not get native dialogue from this row. Score or VO later. Do not pick motion control because you wanted a talking dancer. You wanted a dancer. The mouth is a different pass.

Why the still is step one

Motion control is expensive identity if the still is wrong. The model will faithfully transfer the beat onto a face you do not want, a label that is already illegal, a body that does not match the drive. You will watch a perfect wave executed by the cousin of your talent. That is a successful motion transfer and a failed job.

Locking the still first is the same discipline as I2V, with a stricter framing constraint. I2V can invent motion from a pretty poster. Motion control needs the poster to be castable in the drive’s blocking. A pack shot on a table is a bad still for a full-body dance drive. A full-body still is a bad still for a hands-only product turn drive. Match the job.

People skip step one because they already have a driving clip they like (a trend, a staff dance, a turntable). They attach a website crop of the product and press generate. The website crop is 16:9, three-quarter, label half-cut. The drive is 9:16 full body. The output is a morph. Crop and regenerate the still until the subject sits in the drive’s window. Then run motion control.

People skip step one because the still “is just a character.” Characters drift if they only live in a prompt. Motion control will not invent a consistent person from adjectives plus a dance. Supply the person as pixels.

If you do not have a still yet, you do not have a motion-control job. You have an image job. Do that. If you do not have a drive yet, you do not have a motion-control job either. You have I2V or T2V, and you will accept invented timing. Film or license the clip, or drop the mode.

What not to do this week

Do not use motion control to “add energy” to a pack shot that only needed a slow push. I2V a locked still. Cheaper, fewer files, no framing fight.

Do not drive a clip you do not have rights to. Trend audio is not a licence to the performance in the video you downloaded.

Do not expect facial acting and lips to ride over from the drive. Most transfer is body-level. If the line matters, a lipsync or a sounded generate is a different radio.

Do not motion-control a SKU that has not passed a still audit. Labels warp in transfer when the still was already mushy. Hold the pack in I2V from a locked plate instead, or photograph the hands.

Do not pick the Pro row to debug the still. Seventeen credits of wrong identity is still wrong. Debug at still prices.

The AI video generator lists motion control next to T2V. Adjacent in the menu is not adjacent in the pipeline. T2V invents. Motion control casts a performance you already have onto a picture you already approved.

The Monday radio

• If this week needs a specific dance, walk, or gesture on a specific face or mascot: lock still → lock drive → Kling V3 motion control (Pro if you need that quality tier).
• If this week needs motion but not that timing: lock still → I2V. Skip motion control.
• If this week has neither still nor drive: you are not on this row. Generate a still, or film a drive, or both.

Watch the output against the still on a freeze of the first frame and a freeze of a mid beat. If the first frame already drifted from the still, the still was not held — or the framing did not match. Do not fix that with a longer prompt. Fix the files.

If you need the Pro motion-control row after the still is signed, sign up and attach both files. The still is step one. The dance is step two. The prompt is not a file.

FAQ

Can I generate the still and the drive with the same model?

You can generate the still with an image row and film or license the drive. Generating a “drive” with T2V is allowed only if you accept that timing as the performance and you have rights to use it. The still should still be locked separately so identity is not re-sampled in the transfer.

Why not lock the driving clip first?

You may collect the drive first. You may not run the row first. If the drive is a full-body 9:16, that informs how you compose the still. Collection order can be drive-then-still. Generate order is still-approved, then transfer. Do not spend the motion-control credit while the still is still a maybe.

Does motion control replace I2V for product turns?

Only when you have a turntable (or hand-turn) clip whose timing you must keep. A generic “slow orbit” is an I2V prompt on a locked pack still. Do not buy a driving clip you do not need.
