webReady: output.format must be mp4. Optimizes for web delivery via passthrough, faststart remux, or web encode. See Web Ready Video.
proxy: output.format must be mp4. Always re-encodes for timeline editing. See Edit Proxy.
probe: Use mode: "probe" with a single input. Returns enriched ffprobe metadata on the job record (probe field). No output file. See Probe Media Metadata.
input: Single-input jobs (recipe, probe, single-input ffmpeg) take exactly one of input.url or input.uploadId. Use uploadId for files uploaded via POST /v1/uploads — see Direct Uploads.
extractAudio: output.format is the transcode fallback (mp3, aac, or wav). When the source audio is copy-compatible, the delivered file may use a different extension (for example .aac). See Extract Audio.
