Thanks. I was just wondering if, once the initial compression had been
done, any of the various formats can be converted into each other

I, hence my asking the question!
The "formats" part can be broken down into two pieces.

The outside part is the "container".
.mkv , .mov , .avi are containers

Inside the container are video and audio codecs.

Hi Paul, I know what you wanted to say but that last part didn't come
out right. There are no codecs inside the container. That would be quite
inefficient. ;-)

Otherwise, excellent summary.

Yeah, that should have been "video and audio streams".
