I thought Harmy was only rendering SWD at 720p, which is why the mkv is better as it can retain 24fps: going to official Bluray at 720p means it must be 720p60 and therefore have frame repeats that introduce judder.

If I am mistaken and Harmy intends to render at 1080p24 for Bluray, even though I thought most of his modified source is 720p, then the Bluray will be a substantially larger download for no increase in detail and thus I would still prefer a 720p24 mkv.

Happy to be corrected if I have misunderstood anything.

Blu-ray supports 720p24, but HDMI does not. So Blu-ray players convert 720p24 to either 1080p24 or 720p60. The player decides whether you get judder or not, (hopefully) according to the capabilities of the display.
