Yes. It seems bonkers to me for the BBC to end them. But I've not had any
reaction to pointing out that they are useful, etc. So I assume they won't
be re-instated. :-/

Yes, Linux. The challenge for me is to work out how to get the fetched file
to go onto the tmpfs, then have that processed - ideally having gip give
ffmpeg relevant details - into a 25fps file on my main disc. i.e. I don't
know enough to specify the commands and either get gip to do this, or add
in the relevant ffmpeg call.

Am I right that by using the --command and also --raw I can then run ffmpeg
to do the conversion and put the result where I want? That sounds about
right for what I have in mind. 

I'll look at what the --verbose gives me as per your other email. Someone
elsewhere has said they can get handbrake to do 50 -> 25 fps fairly well.
But that means running that as well unless I can work out what it is doing
on a command level. And IIUC handrake is using ffmpeg anyway under the
hood...
