Although Hannah Fry seems to be on every BBC Four (and BBC2) commission at the moment, I have to agree that she was great on TW and would have been a TW presenter if the show wasn't cancelled.

I also share the same sentiments about Howard, it was like he never went away!

Watching it right now on iPlayer. One thing TW never predicted was that in 2018 studio footage would be often and pointlessly treated to ‘film effect’ processing

Edit: Though having watched it all now the studio footage suddenly reverted to 50i about 30 mins in ?
Did that happen ‘live’ or was iplayer stuck in 25p for the first 30 mins ?

.... and we have had a glitch This Week studio shot insertion for a few seconds











It was all a bit ‘Inside No 9 ‘ ! Mind you BBC 4 is on Freeview at EPG No 9 !

It's 50i (edit: or 50p) from the start for me on iPlayer. Don't know about the original broadcast though.

Edit: the "This Week" glitch is still there so I doubt anyone's been fixing anything.

Do you mean was your iPlayer stuck in 25p or iPlayer in general?

There are 25p fall-back streams ISTR for the web streaming/Smart TV streamed iPlayer. However there aren't any streamed 50i streams - iPlayer is 720/50p on most platforms (Sky iPlayer is 1080/50i aka 1080i25, and there were some legacy DVB MHEG5 iPlayer streams that were 576i ISTR - but I think they have been deprecated)

Well, I’m watching it again now, it’s got a genuine ‘50i fluid’ look. Are you saying it’s 720p50 ? It could be, but looks the same quality as ‘broadcast’ 1080i50 !

BTW 50i from the start this time, so must have been some bandwidth starvation first time round ?

Ah - I'm careful to say 50Hz not 50i these days as there is so much 50p knocking around Wink

Unless you are watching on Sky HD - then it's almost certainly a 1080i25 to 720p50 deinterlace. The highest quality (non-'UHD') iPlayer format (other than on Sky HD) is 720p50. There is also a 540p50 profile at a lower bitrate. The lower-than-540p profiles are p25 not p50. For legacy platforms there are also 720p25 streams still I believe. (These are SDR Rec 709 H.264/AVC 8-bit.)

For UHD iPlayer (which is also HLG) there are 2160p50, 1440p50 and 1080p50 (and possibly a 720p50 now?) streams in H.265/HEVC 10-bit HLG Rec 2020 for live, and there are p25 variants for pre-recorded stuff. (Dynasties is 2160p25)

Sky HD uses Sky's in-house distribution system and uses progressive download (You can start watching before the download has completed but it won't let you start until it thinks it's got enough for you not to run out). I think it's around 8Mbs 1080i25 H.264 (and can carry 5.1 Dolby Digital - all other iPlayer outlets are 2.0 AAC ISTR)

It's around 5Mbs so survives OK - but demanding content exposes the less-than-ideal deinterlacing and compression used - particularly on live stuff. Strictly hammers iPlayer...

Yes - I guess so.

I’ve just taken a look, yes, you’re right, low luma saturated chroma ( notably illuminated ‘smoke’ struggles particularly ( as you’d expect) No where near as bad as I’d have expected though. If you’d told me 15, even 10 years ago I’d be watching HD ( never mind UHD) pictures down my phone line, I’d have called you bonkers! 😎

Yes - 2160p25 HDR at 22Mbs over a phone line would have blown my mind in 2000...

But then moving to 5x1080i TV services in the space of 1xPAL composite SD service is also pretty amazing (and in less than 15 years).

There's an archive episode of Tomorrow's World (from 2002) on BBC4 this Sunday at 2000 - which looking back at Genome appears to have been one of the final editions of the programme barring specials.
It's a Spiderman special so presuming is to tie in with the new one...
