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.
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
- UGC clip assembly and highlight reels — UGC use case.
- Campaign variants that are mostly concat, not kinetic motion — otherwise prefer Remotion.
- Pipelines that must stay on Apple Silicon capacity with private/org pools — private pools.
Integration shape
- Estimate the stitch job (how to estimate).
- Create with an idempotency key (idempotent jobs).
- Observe via signed webhooks (webhook how-to).
- Verify artifact checksum before user publish (artifact verification).
