console.log(outputUrl(job));

Install with npm i @rendobar/sdk. jobs.run() submits and waits, so it returns the finished job in one call.

terminal
curl https://api.rendobar.com/jobs \
  -H "Authorization: Bearer $RENDOBAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"compose","params":{"schemaVersion":1,"output":{"format":"mp4","resolution":{"width":960,"height":540}},"timeline":{"tracks":[{"clips":[{"asset":{"type":"video","src":"https://cdn.rendobar.com/compose/showcase/media/steps.mp4"},"start":0,"effects":[{"type":"sketch"}]}]}]}}}'

Returns immediately with a job id. Poll GET /jobs/{id} or register a webhook rather than blocking on the request.

Chroma key Remove the green screen so the presenter stands in front of a new background. Color A warm cinematic grade: the light pulled towards gold, contrast and color lifted a little, skin left believable. Looks The whole archive look in one word: sepia, grain, dust, scratches, projector flicker and a vignette together. Blur Knock the footage back so a title over it stays readable. Sharpen Crisp up footage that is slightly out of focus. Look at the jacket, the hair and the stone. Denoise Clean the grain a small sensor adds in the dark.
