Re-encoding Bluray content with x265 10bit

[leghorn]

The title's already giving away what I want to achieve. Currently I use MeGUI to create AviSynth scripts: (a) using DirectShowsource, or (b) after indexing the video with DGindexNV. For re-encoding I use Simple x264/x265 encoder with the x265_x64 encoder.

Which is the better way to serve the frames to the encoder, (a) or (b)? Or something completely different? I'd like to avoid the "Handbrake effect" with 8bit pipelining.

Both will achieve exactly the same quality since Blu-rays (except UltraHD Blu-rays) are 8 bit only. Nonetheless, DGindexNV is recommended over DirectShowSource because DirectShowSource is not always frame-accurate and some filter settings might accidentally introduce quality loss.

Only cropping and resizing.

Since DVDs and BRs are 8bit only.... Does it actually make any sense to encode to 10bit?

Yes, 10 bit AVC/HEVC encoding is more efficient than 8 bit encoding even with an 8 bit source. It is especially efficient at avoiding banding artifacts.

Thank you, sneaker! I'll keep that in mind
