!!! note "`generate_dv` and a hand-made HYBRID"
A service that fetches the HYBRID variants itself (HDR10 and DV) must also fetch
HDR10P when `track_request.generate_dv` is set and the title has no DV track.
The conversion needs an HEVC HDR10+ track as its base.
`get_tracks_for_variants` does this for you.
!!! note "Read the request, don't second-guess the user"
Services may narrow `track_request` for hard technical constraints (e.g.
*"this service delivers HDR only as HEVC"*), but must **not** filter
