Formats & I/O

What Forged reads and writes, how sequences are addressed, and where video sits.

Reading

Read takes stills, ####-numbered sequences and video. EXR (including multipart and multilayer), DPX, PNG, JPEG and TIFF decode natively; video goes through ffmpeg. Only the layers actually demanded are decoded, so a 40-layer EXR costs what you ask of it, not what it contains.

first / last bound the sequence; before / after decide what happens outside it (hold, black, loop); frame_mode decides how project frames map to file numbers.

Writing

Write renders EXR (multipart), DPX, PNG, JPEG, TIFF and PPM, with the output display transform applied at the doorway. Renders run on a background thread with a queue, progress and cancel; the same engine runs headless on a farm, so interactive and farm output share hashes and therefore pixels.

Video

Video encode (h264 / ProRes / VP9) is available through the render queue.
