Motion & media
Models and quality settings inside the 3D Website Builder.
Hero stills
Default Seedream 4.5 (fal) for cinematic backgrounds. Nano Banana Pro and Nano Banana (API-Easy / Gemini) unlock on Premium ($200/mo)+ for higher-end stills. Image resolution tiers (1K / 2K / 4K) follow your plan — 2K/4K need Premium+.
Motion video
Veo 3.1 Fast (Google / API-Easy) is the default motion engine on paid plans and supports first→last frame where enabled. LTX 2.3 Fast (fal) is optional for single-image image-to-video; set `FAL_KEY` or `fal_key` on the server. LTX on fal does not replace two-keyframe mode — use Veo for that.
2K/4K video output requires Premium+. Match aspect ratio (16:9, 9:16, 1:1) to your layout.
Site HTML (“Site AI”)
The Site AI picker chooses which Gemini profile bills and routes full-site HTML generation. It does not change how you write prompts in chat — it affects cost multipliers and backend routing.
Quality summary
Video: 720p/1080p on paid plans; 2K/4K on Premium+. Image: 1K on paid; 2K/4K on Premium+. Extend clip (continue a finished video) uses fal LTX extend on Pro+ with the same `FAL_KEY`.
