Chaining clips across models
Use the right model for each shot type, then stitch them into one MP4.
Chaining clips across models
The pitch: no single model is best at everything. Veo 3.1 owns lip-sync, Kling 3.0 owns cinematic motion, Seedance owns audio-native generation, Runway owns camera control. Varosity lets you mix-and-match per shot.
A simple 4-shot example
| Shot | Type | Best model | Why |
| 01 | Wide establishing | Kling 3.0 Pro | cinematic motion, cheap |
| 02 | Talking close-up | Veo 3.1 | best lip-sync, native audio |
| 03 | Action beat | Seedance 4.5 | audio-native, multi-shot intent |
| 04 | Hero close-up | Runway Gen-4.5 | camera control + motion brush |
Set up: 1. Create a project. 2. Click + Add your first shot, pick Kling, write the wide. 3. + Insert after, pick Veo for the dialogue, paste your line. 4. Repeat for shots 03 and 04. 5. Hit Render this shot + all downstream to fan out renders. 6. Once everything's done, Render final stitches into one MP4.
When you don't know which model to pick
Click the Smart Route chip in the inspector. It sends your shot description to a routing LLM (OpenRouter / Claude Haiku) which ranks the top 3 candidates with reasoning. The chip pulls exclusively from your configured providers — it'll never recommend a model you can't use.
Cost discipline
The cost line in the inspector estimates per-shot at the registry's
pricePerSec. The dashboard's Renders tab shows the total spent per
final cut. There's no markup — what fal/Runway/etc. bill is what you pay.
