Hosted on fal (R4): three OmniHuman endpoints active - original, v1.5 (updated 21 Apr 2026) and v2 (updated 15 Oct 2026). All take one image of a human figure plus an audio file and return a video whose length equals the audio; billing is per second of audio/video ("duration ... as used for billing"). v2 schema (R1): required image_url + audio_url; audio wav/mp3, max 15 MB, 4-300 s; image jpeg/png/webp/bmp/tiff/gif/heic/heif, max 30 MB, aspect ratio 0.4-2.5, 300-6000 px per side; optional prompt for scene, movement and camera in Chinese, English, Japanese, Korean, Mexican Spanish or Indonesian; no resolution, mask or turbo parameters exposed. v1.5 schema (R2): audio must be under 30 s for 1080p or under 60 s for 720p (the schema says 720p is "faster and higher in quality"), turbo_mode trades slight quality for speed, and mask_url restricts speaking to the person in the white mask area - the only multi-person control in this family on fal.

Rendered price lines (R3, 23 Oct 2026): v2 $0.105 per second, v1.5 $0.16 per second - so a 60 s monologue is about $6.30 on v2 vs $9.60 on v1.5 (720p only). Selection: v2 for long single-speaker pieces (explainers, narrated shorts) and prompt-directed motion; v1.5 when two people are in frame and only one should speak, or when a fixed 1080p clip under 30 s is needed. Unverified: output resolution/fps of v2, quality vs dedicated lip-sync models (see C3-B435-01), and the underlying ByteDance licence terms passed through by fal.
