Guide

A video stitching API that hides FFmpeg footguns.

Product teams need “assemble these clips in order,” not an arbitrary shell. RenderMac’s ffmpeg.stitch_export.v1 service concatenates ordered media URLs on Apple Silicon with estimate → create → webhook → verified artifact.

UGC pipeline diagram: clip ingest, stitch, caption burn-in, deliver
Stitch is usually stage two in a UGC pipeline — after ingest, before optional caption burn-in and delivery.
Service ID: ffmpeg.stitch_export.v1 (see OpenAPI / docs). Inputs are typed media URLs plus bounded codec/audio-copy choices — not free-form FFmpeg CLI.

When stitch is the right service

Integration shape

  1. Estimate the stitch job (how to estimate).
  2. Create with an idempotency key (idempotent jobs).
  3. Observe via signed webhooks (webhook how-to).
  4. Verify artifact checksum before user publish (artifact verification).
