Hey again! Been a while; I’ve returned to my own fan edit projects for the first time in a while, and if it’s all right, I’m back with a couple more fan editing questions (just two this time hehe)

How can I export without or with minimum compression/pixelation in dark areas of the image? My current efforts have seen heavy pixellation. My process is encoding the Blu-Ray Rip in Handbrake at max quality, then exporting as .mp4 or .mov. I’d love to have maximum visual quality, is it an mkv thing? I’m on the free version of DaVinci Resolve so I may be limited there
How can I export DTS audio? Currently I’m just exporting AAC, which has so far been fine, but again, max quality would be really nice

I know I’ve had a lot of questions, but exporting’s turned out more complicated than I thought!

These exports are just some quite basic LOTR edits (added musical overtures, musical intermissions, chapter titles for the now six parts, and some minor cuts/trims), and I’d love to be able to have them in as high quality as possible. I may bring them to this site.
