  -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-soft.mp4"},"start":0,"effects":[{"type":"sharpen","amount":0.7}]}]}]}}}'
