Re. file sizes doubling.

In my expereince some are and many aren't. I can't quite get a handle on 
why. I too have seen 1.5 hour films go to 5.5GB where before I would 
expect 2.5 - 3. Yet one episode of Killing Eve from the last series 
yields the info below for the full HD and the 1280x720 versions.


Hardly an increase in file size, but then the compression is different 
and may or may not suit the type of scenes within the episode I guess. 
Compression is a bit of a mystery to me...


I've always been impressed by the quality of the 1280 x 720 on our 4K 
UHD screen and while the quality is subjectively better in certain areas 
with the Full HD, it's not something I'd do every time if it was 
doubling the storage requirement.


To be honest I find that better sound has more impact on the 
"watchability"/enjoyment of a lot of programs than the video. We stream 
a lot these days from Netflix/Disney+/Prime... which is going to be a 
lot more compressed than the video in these files but the Atmos or DTS 
audio through the surround speakers and sub. on the streamed content 
make such an impact, which (even with all the processing the audio 
system can throw at it) the iplayer files never match.


If anyone's wondering from the info, I store most things in .TS unless 
I'm ripping my DVD's/BluRays mainly because that's what all the off air 
recordings from whenever were recorded in. Must admit I'm no longer sure 
if this is the best way to do this with iplayer files but hey.

I've seen a doubling in file sizes to approx 4GB per hour when
selecting fhd video quality


Both my simple mathematical calculation and the above linked page 
suggests that they shouldn't be more than about 1.5 to 1.6 times the 
size of an HD download.

Whether it is true full HD or not, I'm not sure, but the files seem to
report they are 1080p

A further thought ... if the hvfhd mode above was really 1080p, one

JOOI, I've investigated this further by downloading the first episode of

it was 720p, so I'm still not aware of anything that suggests that

https://github.com/get-iplayer/get_iplayer says,

] It is often possible to download other content such as red button

so I guess that "/often/ possible" indicates it's already known not to
