Luma Ray3.2 face tracking vs Kling motion control: pick by input

Use Luma Ray3.2 when you want a generated shot that keeps an actor's expressive performance, and use Kling 3.0 Motion Control when you already have a still and a clip whose movement it should copy. They start from different inputs. On Sume you can run the Kling route today; Ray3.2 is not in Sume's video catalog.

Luma released Ray3.2 on June 9, 2026, and says its API is available for the first time with this model (read 2026-10-07).

What Luma says Ray3.2 does

Luma's announcement lists the control surface below. It does not give prices or credit costs on that page, so none are quoted here.

What Kling motion control does instead

Kling's route does not generate a scene from a prompt. It takes a still of a character and a motion reference video, then animates the still with the movement in the clip. The output length follows the reference clip, from 3 to 30 seconds by Kling's guide (read 2026-10-07).

On Sume, POST /v1/kling/3.0/motion-control takes image_url or a ready avatar, a public HTTPS motion_video_url, and duration_seconds. It bills $0.1575 per second, and it keeps the reference clip's audio by default (keep_original_sound).

Pick by the input you already have

• You have only a script and want a cinematic shot with controlled keyframes: Ray3.2 is built for that, and Sume cannot run it.
• You have a still of a character and a phone clip of the move you want: Kling motion control.
• You need to put a different person into an existing video, keeping its motion and sound: H3 Max Recast on Sume takes one to four photos.
• You need a talking still driven by audio: that is a lip-sync route, not either of these.

What a Sume run looks like

A 10-second reference reserves $1.575, captured on completion and refunded on failure. Output is an MP4, with no HDR or EXR delivery on this route.

If Ray3.2's 16 keyframes are the reason you came, the nearest Sume approach is chained jobs with first and last frames, which is described in 16 keyframes against chained jobs. It is a workaround, not a match.
