Changing Q_MAX appears at the moment to have helped. I don't understand why the lens makes its own thumbnails; surely it should use the Nautilus ones by default so work is not duplicated?
I noticed when I cleared out its cache that it was also thumbnailing everything possible in places like the Chromium web cache (including images) which suggests video-lens is doing a lot of unnecessary work.
