Will this be a BD25 or BD50?
The current plan is to do the initial release as a 30-40 GB mkv, so a bluray version will be BD50.
Guess you’re using H264 and not H265 which is the vastly better codec including halving the filesize. I’d rather wait for the BD anyway.
Commercially perhaps, but the free x265 codec is immature and inefficient.
Hi10P x264 is superior but has low hardware compatibility which rules that out as useful too.
