Lip-sync and motion control cost per clip: H3 Max, Fabric, Kling

Three Sume tools turn existing media into new video. MiniMax H3 Max lip-sync costs $0.0625, $0.10 or $0.20 per audio second at 480p, 768p or 1080p. VEED Fabric 1.0 costs $0.1875 per audio second at 720p. Kling 3.0 Motion Control costs $0.1575 per output second. A 10-second clip is $0.625 to $2.00, and 100 clips are $62.50 to $200.00.

How each is billed

H3 Max lip-sync bills by ceil audio second: the Sume docs give a fal list of $0.05, $0.08 and $0.16 at 480p, 768p and 1080p, times the 1.25 house margin. The audio must be 5 to 14.8 seconds, Sume-hosted and under 10 MB. The docs' own example: a 5-second 768p clip reserves $0.50 (5 x $0.08 x 1.25).

Fabric is $0.1875 per audio second at 720p, up to 300 seconds. The docs' example: 5 seconds reserves $0.94 (5 x $0.1875 = $0.9375, rounded up to the cent). Kling 3.0 Motion Control is ceil(motion video second) x $0.126 list x 1.25 = $0.1575, for 1 to 30 seconds.

A vendor reference point

fal's pricing page lists Kling Video v3 Image to Video [Pro] at $0.14 per second (read 2026-10-07). That is Kling's image-to-video product, not Motion Control, which the Sume docs list at $0.126 per second from fal in August. Different products, so do not subtract the two numbers. The page also lists the H3 Max text, image and reference-to-video models at $0.05 per second (read 2026-10-07); that is a different product from lip-sync, so I do not compare it with the lip-sync rate.

Choosing among them

Use lip-sync when the video exists and the voice is new: you pay by audio length, which is capped at 14.8 seconds. Use Fabric when you have a still and a voice track and want a talking clip, with up to 300 seconds. Use Motion Control to drive a character image with the motion of a reference video, with output length following the driving clip.

The 480p lip-sync draft at $62.50 per 100 ten-second clips against $200.00 at 1080p is a 3.2x spread. Draft cheaply, then re-render only the keepers.

Limits worth knowing

Fabric's audio must be hosted on Sume and under 10 MB, the same as lip-sync. Sume's separate Avatar Fabric route is experimental, priced at $0.3024 per second at 720p, and the docs say not to build production on it. These tools are metered per job.

A localization example

Take one 12-second English video and dub it into 5 languages with H3 Max lip-sync at 768p. Each dub is 12 x $0.10 = $1.20, so 5 languages cost $6.00. For 20 source videos that is $120.00. At 480p it falls to 12 x $0.0625 = $0.75 per dub, $75.00 for the 100 dubs, and at 1080p it rises to $2.40 per dub, $240.00.

The audio is separate. You need the translated voice track, which you can produce with TTS at $0.0475 per 1,000 characters; a 12-second line of about 160 characters is $0.0076. The voice is a rounding error next to the video, so the resolution choice is the real lever.
