So although there is only a 50fps 720p version produced by Video Factory, there is actually a 1080i stream which is 25fps but runs at 8000 kbps. Of course that >means though that it will still be significantly bigger than the 50fps 720p version. Around 3GB/hour?
The BBC and other broadcasters transmit many films on HD satellite channels at 1080i 25fps with AC3 sound at bit rates up to 9Mbit/s if my satellite receiver is to be believed. I don't recall having seen any 50fps films being broadcast. Why not, if increasing the frame rate yields greater improvement than increasing resolution on large screens? Having seen the farce of the FLAC consultation, I am sceptical about the subjective assessments. Maybe the film makers' assessment is different from the BBC's.
According to the get_iplayer wiki there is an HVF 540p25 mode which it calls HVFxsd, and I have used it. That mode does not appear in the list in the blog.
