Is HEVC (8-bit)/AAC a good, modern CODEC combination for reducing library size without compromising quality? I’m about to start a library re-encode and wanted some feedback.

    While I tend to avoid encoding wherever possible, I use H265 10Bit at low RF to archive non-critical libraries (old TV shows in some users personal libraries, 1080p movies more than 1 year old and over 20gb etc…).

    my average size reduction going from a 1080p Bluray remux of 35-40gb is about 50% with no significant effect to image quality. High action or high grain movies end up a bit larger, slower movies with no action and most animations compress a bit smaller. works well overall.

    basically any modern device can decode them and the image quality tends to be a bit better than 8bit.

    I’d like to go with AV1, but very few of my client devices can decode it, so its not worth the trouble to save a few percent,

      I have a problem with 10-Bit though. When I try to encode more than 1 file in 10-Bit with the HEVC_AMF ffmpeg encoder, my CPU usage goes to 100% and stays. And with 1000s of files to do. Well, you can imagine. Ugh!
