Many thanks for your "usual" comprehensive reply.
I'm guessing the 24Hz framerate is as a result of many of my files originating in the U.S. They always seem to do something different to us.
If I was to convert an MKV to another format, would that make any difference, or will the framerate, get carried through to the conversion?
I've got Any Video Converter on my PC and I've discovered that in the Video options I can change the framerate to 50. However, I've started the conversion and it's going to take about an hour for a video which runs for about 80 minutes.
Do you have experience with the framerate converter you mentioned, if so, do you think it would be any quicker?
Nothing to do with the US. It's down to the fact that most of the content is derived from blu-ray. The blue-ray spec for full HD (1920 x 1080) only supports up to 1080p24. Which is what you get on a blue-ray disk albeit at a much higher bitrate than HD broadcasts.
Though the spec does support 720p (1280 x 720) at 50fps. This is the same as HD broadcast content using the AVC/H264 video compression codec, though no UK broadcaster ever used 720p50 (because 1920 x 1980 sounds superior (it's not for much content)
There is a later spec that supports Full-HD progressive at 50.60 fps.
Recoding video is processor intensive so your question is impossible to answer. It depends on the amount of memory your PC has and the processor and speed of the storage options.
If you have a a laptop with a sort of spec you can get at sub £1000,00 prices you might have to let it work overnight.
For example my Core I7 laptop with a 2TB SSD boots Windows 64 in about 10 seconds.
One hour seems pretty quick to me. To get any faster you need something much quicker and more expensive. . It's still faster than real time.
Recoding the framerate takes a long time, changing the container from say .MKV to say .ts is quick because the video is not recoded at all.
Leave it overnight and check if the problem is solved,
