Just checking BGT on ITV Hub.

Commercials are 704x396 at 25fps bitrate of 1Mbs

Show ramped up from 704x396 very quickly to 1024x576 at 25fps 1.46Mbs h.264/avc video and 98kbs aac audio. (Whether that 1024x576 is sourced directly from 1920x1080 - and thus has detail up to 1024, or is a 702x576 scale to 1024x576 to keep square pixels, but with no detail above 702, I don't know)

Looks pretty similar to All4.

A far cry from iPlayer's 1280x720 at 50fps 4.6Mbs h.264/avc video and 128k aac audio.

The 50fps vs 25fps is crucial - it means iPlayer looks pretty much identical to watching Freeview/Freesat/Sky/Virgin, and ITV Hub, All4 (and Amazon Prime, Eurosport player etc.) all look sub-standard and second class.

AppleTV+ will support 4K HDR playback with HDR10 and Dolby Vision & Dolby Atmos sound.


So same as Amazon Prime and Netflix then. Anything less than HDR10 and/or Dolby Vision, and anything less than Dolby Atmos sound, would leave Apple TV+ as 'second rate' in comparison.

Bit like SkyQ all nice looking but lacks HDR, HLG
