- A job must have at least one standard or segmented output; creating jobs with only playlist outputs will not work.
- Playlist outputs will ignore most output options, except for url, base_url, filename, streams, public, and type.
- If a segmented output is uploaded to temporary storage, it will be uploaded as a ZIP archive.
