Be careful. As others have said mp4 and mkv are container formats and this is what is associated with the extension. It's more important in the what can play the video decision.

The compression (or not) comes from the codec, but again some codecs can do both compressed (lossy ) and uncompressed (lossless)

Note also just to confuse folk, there is an MPEG4 codec, which I thought for a while was what mp4 used.

Unfortunately none of this is simple and ultimately the only way I found to settle on what I wanted for my video collection was try a number of containers and compressions and evaluate which gave me the best overall result over many different types of film and tv program. (Plus side that took a few weeks with bottles of wine and the better half helping evaluate the results...)

Then it was the case of what simplified the various sourcing processes and finally - compromise, which I think is where you're at here.

To be honest, with the number of streaming services around these days I'm more selective and don't keep as many broadcast items as I used to. - It costs me less to subscribe to 3 or 4 services than it does to build and run a file server for a 10 year period. The added advantage is that many of the things I recorded in 1080 x 720 or whatever are now streamable in full HD and even with the bitrate that comes down the line to me it's better than my 10 year old recordings.

Oh, I was lead to believe that .mp4 was a lossy format, where as .mkv is not.

That is what I was trying to avoid

As far as I know conversion to mp4 is just changing the container format, there’s no recompression.
