# Video models
> Fourteen image-to-video models, one panel. Pick the engine that turns a still frame into motion at the duration, resolution, and price you need.
The Video panel turns a promoted shot into motion. Every model takes the shot as its first frame and fills in movement. The model decides duration, resolution, audio, and cost. Pricing is in LTB tokens at `1 token = $0.05`.
{/* TODO: capture models/video/01-panel.png — video generation panel, 16:9 */}
## How the panel works
A promoted shot opens the Video panel. The left side shows the first frame and a prompt field. The right side carries the model picker and the output options the chosen model supports.
`Kling 3.0 Pro` runs by default for single-image input. Multi-image input — feeding three reference shots of the same character — switches the default to `Kling O3 Pro`.
The right panel only renders options the active model supports. Resolution, aspect ratio, and audio fields appear or disappear when you switch models, so an unsupported combination cannot leave the browser.
## Four levers control the cost
Every model exposes a subset of four levers. Each lever has a direct effect on tokens charged.
| Lever | Range | Cost effect |
| -------------- | ------------------------------------------- | ---------------------------------- |
| `Duration` | `3s` to `20s` (per model) | Linear — tokens scale with seconds |
| `Resolution` | `480p` to `4K` (per model) | Each step roughly `2x` to `4x` |
| `Aspect ratio` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4`, `21:9` | Usually no cost change |
| `Audio` | `on` / `off` | `1.25x` to `2x` when supported |
Generation time runs `30s` to `5min` depending on the levers above. Results land in the project library and are ready to share or download.
## Pick by use case
The fourteen models cluster around four typical jobs. Start with the recommendation that matches your job, then check the full pricing table at the bottom.
`Kling 3.0 Pro` is the panel default. Supports end-frame, reference images, elements, and multi-shot. Pricing is `$0.112/sec` silent and `$0.168/sec` with audio at `1080p`. An 8-second clip costs `22 tokens` silent or `32 tokens` with audio.
`Kling O3 Pro` is the only model that accepts multi-image input. Feed front, side, and full-body shots of one character and the camera can move without the face drifting. Use this for series, ad campaigns, or any project where one identity recurs.
`Veo 3.1` is the only model with a `2160p` (4K) SKU. The cost jumps from `$0.20/sec` at `1080p` silent to `$0.40/sec` at `4K` silent, and `$0.60/sec` with audio. Lock the cut in `1080p` first, then re-render the keepers in `4K`.
Both Sora models support durations up to `20s` — the longest range in the panel. `Sora 2` runs at `$0.10/sec`; `Sora 2 Pro` reaches `1080p` at `$0.50/sec`. Audio is not supported. Use them when one long take serves the story better than two short ones stitched.
`LTX 2.3` runs at `$0.06/sec` at `1080p` — the cheapest `1080p` in the panel. `Seedance 1.5` reaches `$0.030/sec` at `480p`. Both ship silent only. Pick LTX for previews at full resolution, Seedance for storyboard checks.
`Hailuo 2.3 Pro` charges `$0.49 per clip` regardless of length or resolution. `6s` fixed, no audio, no end-frame. The flat rate makes invoicing and budget approval trivial when the deliverable is one finished cut.
## Where to spend less
Audio is the largest single lever. On `Kling 3.0 Pro`, turning audio off drops `$0.168/sec` to `$0.112/sec` — a 33% cut. On `Veo 3.1` at `1080p`, audio off drops `$0.40/sec` to `$0.20/sec` — half. Compose music and narration in post if the model output is only the picture you need.
A few concrete pairings show the spread.
* `Veo 3.1` · `1080p` · `8s` · silent = `38 tokens` (\$1.90)
* `LTX 2.3` · `1080p` · `8s` · silent = `11.6 tokens` (\$0.48)
* `Seedance 1.5` · `480p` · `5s` · silent = `3.75 tokens` (\$0.19)
For social previews, the cheapest pairing often looks identical to the most expensive once it lands in a feed at `720p`.
## Full pricing table
`$/sec` is at `1080p` unless noted. `→` separates silent and audio-on rates.

| `Hailuo 2.3 Pro` | `6s` | `1080p` | flat `$0.49 / clip` |
| `Wan 2.7` | `5s` / `10s` / `15s` | `720p`, `1080p` | `0.10` (`720p`) · `0.15` (`1080p`), silent only |
| `Sora 2` | `4s` / `8s` / `12s` / `16s` / `20s` | `720p` | `0.10` (silent only) |
| `Sora 2 Pro` | `4s` / `8s` / `12s` / `16s` / `20s` | `720p`, `1080p` | `0.30` (`720p`) · `0.50` (`1080p`), silent only |
LTB does not cap model choice by plan tier. As long as your token balance covers the request, the most expensive model on the list is available for back-to-back generation. Decide the working model per project to keep costs predictable.
## After generation
Finished videos save to the project library. From the card you can play, download an `MP4`, publish a share link, or regenerate with a new seed at the same settings. Send the cut to the timeline editor for trimming, captions, and BGM.
