Hey @Pete.IRL you could give my .pp3 file for basic starts a go… It’s sets up RT in a basic way, but I’d say the important thing is the resize (look in the Transform’ tab), which is set to the pixls.us preferred size of 1920 x 1080. When you hit the cogs to produce your output, set jpeg to 92 for quality with a balanced approach… Should end up with a file of about 500kb at the correct size.
There’s a few other things I set using this basic start, but have a look at the .pp3 applied to one of your shots to see what else I use; first though always apply the Neutral processing profile (essentially turns off everything so you start a fresh) before applying this file/.pp3.

Happy to help if you have questions…
