fal-upscalelisted

# fal.ai Video Upscale Upscale low-res video (e.g. ltx2's 768px output, 720p AI clips, old footage) to 1080p or 4K using fal.ai's hosted upscalers. Designed to bolt onto the ltx2 pipeline so generated clips ship YouTube-ready. ## When to use which model | Endpoint | Best for | Notes | |--------------------------------------|------------------------------------------------|-------| | `fal-ai/topaz/upscale/video` | **Default.** Polished pro-grade upscale. | The standard. Topaz Video AI under the hood. | | `fal-ai/bytedance-upscaler/upscale/video` | Cheaper alternative, faster turnarounds. | Use when Topaz cost stings on long clips. | | `fal-ai/wan-vision-enhancer` | Wan-family AI clips, restoration + enhance. | Vision enhancement, not pure upscale. | > **AuraSR (`fal-ai/aura-sr`) is image-only.** Don't try it on video — use Topaz for video. ## Auth 1. Grab a key from https://fal.ai/dashboard/keys 2. Set the env var: ```bash # bash / zsh / WSL export FAL_KEY="fal_xxxxxxxxxxxxxxxx" # Windows PowerShell (persistent) [Environment]::SetEnvironmentVariable("FAL_KEY", "fal_xxx...", "User") # Windows cmd (current shell) set FAL_KEY=fal_xxxxxxxxxxxxxxxx ``` The `fal_client` library auto-picks up `FAL_KEY` from the environment. ## Install ```bash pip install fal-client ``` ## Pricing (Topaz, as of 2026) | Output resolution | Price per second of video | |-------------------|---------
