Short answer: For live-action brand ads in Motioneed Film, pick the video model by budget, by whether the shot needs its own sound, and by how long one shot must run. Kling 3.0 Pro costs the most at 2 credits a second (720p); Seedance 2.0 Mini is the cheapest model with scene sound at 0.9; HeyGen Video is the cheapest overall at 0.5 but makes no sound of its own. Seedance 2.5 is the only one that runs a single shot up to 30 seconds.
The seven models side by side
Every Film is planned first (free), then rendered on the model you pick. Each model is priced by its own cost. Rates are credits per finished second.
| Model | Picture | Own scene sound | One shot runs | 720p | 1080p |
|---|---|---|---|---|---|
| Kling 3.0 Pro | 720p | Yes | 3–15 s | 2 | 2.5 |
| Kling 3.0 Standard | 720p | Yes | 3–15 s | 1.5 | 1.9 |
| Seedance 2.0 | 720p | Yes | 4–15 s | 1.8 | 2.3 |
| Seedance 2.5 | 720p | Yes | 4–30 s | 2.8 | 3.5 |
| Seedance 2.0 Fast | 720p | Yes | 4–15 s | 1.1 | 1.4 |
| Seedance 2.0 Mini | 720p | Yes | 4–15 s | 0.9 | 1.1 |
| HeyGen Video | 768p | No (the film's music still plays) | 5–15 s | 0.5 | 0.6 |
1080p is the same render upscaled, so it costs a quarter more than 720p.
What a 15-second ad costs on each
A Film is charged for the seconds it renders. A 15-second spot at 720p:
| Model | Credits for 15 s |
|---|---|
| Kling 3.0 Pro | 30 |
| Seedance 2.5 | 42 |
| Seedance 2.0 | 27 |
| Kling 3.0 Standard | 22.5 |
| Seedance 2.0 Fast | 16.5 |
| Seedance 2.0 Mini | 13.5 |
| HeyGen Video | 7.5 |
A credit costs between $0.19 (Ultra) and $0.375 (the $15 pack), so the same 15 seconds runs from about $1.40 on HeyGen Video to about $15.75 on Seedance 2.5 at pack prices. A render that fails gives its credits back.
How to choose
- Sound matters in the shot (a pour, footsteps, a door): use any Kling or Seedance model. HeyGen Video renders silent; the film's score and voice still play over it.
- One long, unbroken shot: Seedance 2.5 is the only model that holds a single shot past 15 seconds, up to 30.
- Lowest cost per test: draft on Seedance 2.0 Mini (with sound) or HeyGen Video (without), then render the keeper on the model you prefer. The plan stays the same between renders.
- The top of each family: Kling 3.0 Pro and Seedance 2.5 are the dearest in their lines; Standard, Fast and Mini trade price for the lighter variant of the same family.
We do not rank the models on picture quality here: that depends on the shot, so the honest test is your own brief. Planning is free, and a short 720p draft on a low-cost model shows the plan before you spend more.
What stays the same on every model
- The plan: shots, lines, voice and music are written first, and you approve them before anything renders.
- The score and the voiceover, which Motioneed adds after the picture.
- Lengths: a Film runs 5 to 45 seconds on a paid plan; the free plan makes one Film at 720p, up to 10 seconds, on any model.
Film or Motion?
Film is for people and places on camera. If the ad should show your actual product interface, logo and copy, use Motion instead: it builds the video from your real website, and costs 0.5 to 1.8 credits a second depending on the writing model. See the pricing page for both.
