[HELP] how to using x265 in Hybrid correctly?

[ssdde]

i'm try to using x265 to encode 720×480 footage to 1920×1080, but in x265 tab, there are so many settings, such as frames, motion, quantization, rate control, and so on.

in x264 i only need to set Average bitrate, nothing need to set, but x265 seem too difficult, even watched help right side, so is there some recommended settings in using x265?



and another small problem, when i encoded file with Hybrid x265, in potplayer it can't display the thumbnails, don't know why, x264 is OK, don't has this problem, and in other x265 film not using Hybrid, is also can display the thumbnails.
