PRICED DRAFT — MANUAL REVIEW REQUIRED source: fal.ai pricing metadata source_url: https://fal.ai/models/fal-ai/ltx-2.3-quality/extend-video exact_model_mode: fal-ai/ltx-2.3-quality/extend-video original_unit: Your request will cost $0.0024075 per megapixel of generated video data (width × height × num_frames), rounded up. Only the generated extension segment is billed — num_frames includes the context overlap, but your source video's own frames are never billed, even though the returned file contains the full stitched video. For example, if you extend a video at 1280 × 720 with num_frames = 121, the generated segment is ≈112 MP, and your request will cost $0.270. method: fal generated-extension megapixel price with fal image-size preset pixels result_base_price: 0.26964 result_price_formula: Math.ceil((((params.resolution ??
