Thanks again Paul!
I've worked a bit with a Video camera recording services of worship in our church.
The Canon video camera allowed selection of high definition [ don't know the figures off the top of my head!] or lower definition for longer recording times. Maybe three or four variations.
Seem to remember settling on one below the highest definition - but with results that can be shown very clearly on 60 to 75 inch High Definition TV's. [i.e. BIG]
Another question if you care to answer - or tell me to look in the instruction manual! Would the recording definition on a Mavic mini be adjustable?
Once again - thanks from this Aussy ex-farmer.
