For some time new additions to iPlayer have been at a default HD frame rate of 50fps. As if that wasn't bad enough, it seems that new programmes are being broadcast at 50fps. Case in point: Canal Walks with Julia Bradbury on BBC4 this week.
I see no noticeable difference in the picture quality but then I don't have a 60" 4K TV. For me, the only effects are bad ones: the storage required for each programme is doubled (a 30-minute episode weighs in at 1.3GB) and moving the files elsewhere takes twice as long, as does any sort of processing or recoding. Presumably, this also affects on-box operations like decrypting. Also, my network connection to the Hummy, which is via Powerline, is no longer fast enough to play the new recordings on other networked devices. I'm having to download the files to my PC (which takes twice as long) and recode them to 25fps with Handbrake (which also takes twice as long).
Can anyone tell me what benefit there is in upping the frame rate from 25 to 50fps?
