[HELP] how to using x265 in Hybrid correctly?

[Selur]

some additions to that:

Just wonder why use x265 for 8bit DVD source?

because you encode to 10bit to avoid banding an getting better compression
(compression is even better with 12bit, but 10bit is a Main profile and supported by newer hardware)

If you need master video for archive, it is better to compress it to 10 bit ProRes422.

No is you archive a proper master I would use a lossless compression.

If you want to create x264/265 master video for archive and future editing, or future transcoding by Youtube/Vimeo you need to use very high rate quality, short GOP, no b frames.

short gop is only good for editing, YouTube doesn't really care about gop size or b-frames and Vimeo probably doesn't either.

In VUI tab make sure Luma Range, Color prim, Transfer charact, Color Matrix are selected and set to Rec709.

Luma range is probaly tv scale when coming from a DVD.
