Many thanks, Martin, I much appreciate the time and interest you have shown in giving me these links. I've browsed a few of the demos and tutorials and increasingly realise just how much Templot has to offer that I still don't know about and don't use. It really is the most remarkable program.
I can see the different qualities of the different systems - but OBS, Twitch, FBR etc are all totally new to me, and inhabit an area of computer-land of which I am totally ignorant. I have modest computer literacy at a basic level at best - and the last "job" I need on my list at the moment is another learning curve! I'm optimistic that saving the edit in Movie Maker just once will significantly improve the quality over the first group of recordings, so I'll press on with the next one, upload that, see how that replays on YouTube and then take it from there. Perhaps I could let you know when I've done that, and you could let me know what you think again then, please? The recording that Zoom delivers is an MP4 file with no other options, so I fear we are stuck with making the best of that.
Thank you again, Martin,
Kind Regards,
Laurie Adams
