x265 produce smaller file sizes but it is rather slow to transcode and less supported on different hardware players. It useful if you have 10 bit 422 source and want to keep all that bit depth and color data in final video. But again, 10 bit 422 x265 is very slow to transcode. Just wonder why use x265 for 8bit DVD source? If you need master video for archive, it is better to compress it to 10 bit ProRes422.
Settings also depends of your needs:
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.
If you want to create Blu Ray disc, you need to preserve Blu Ray specs and limits. There is a checkbox in Hybrid for both x264 and x265 for that.
If you want simple final compressed file for computer collection, use normal rate quality, long GOP, b frames enabled.
Use presets. Don't forget to click <- arrow icons to apply Preset/Tune settings. For example quality x264 looks like this:
Constant Rate Factor 19-18 (or 16-14 for extra higher quality)
Profile Level High, 4.1 for up to 30fps sources or Level 4.2 for 50/60fps sources
Preset - Medium or Slow. (Don't use Slower or higher - they are too slow and less compatible)
Tune - Film for something that looks smooth (or Tune - Grain to better preserve sharp grainy video structure).
Reference keyframes - 3, b-frames - 1 (blu ray and many legacy hardware players limitations) Don't recommended to add more than 5 reference keyframes, because it will slow down transcoding.
For extra high Blu Ray compatible quality use GOP size min: 1, GOP size max: same as framerate (--min-keyin 1 --keyint 25 )
For more compressed sources with more b-frames you set GOP size min: 0, GOP size max: 250 (10 times more than framerate)
In VUI tab make sure Luma Range, Color prim, Transfer charact, Color Matrix are selected and set to Rec709.
