x265 Encoding

[yukukuhi]

Hey there folks
I have 2 questions to ask regarding x265 encodings. The first one is about which GUI to use megui, handbrake or hybrid?

And the second one is about what's the best x265 quality /compression settings to keep for HDTV Rips like .ts & .m2ts Source Footages?

It would be much appreciated if some of you guys help me with this problem.

Handbrake is the easiest GUI to use. You will have to tweak the default settings as they are crap. Also not the latest version of x265. You can get perfectly acceptable results with Handbrake.

MeGUI and Hybrid are more complicated but IMHO you can get better results with these. Hybrid has more filters and tricks than MeGUI. Both are updated regularly and usually have the latest version of x265. Both are quirkt at times but worth learning. Staxrip is also worth a look.

As for the settings, x265 is strange sometimes. A q setting of 20 to 22 usually yields fair results. Sometimes you can get away with q 25. It all depends on what your aim is and your source material (grain, darkness etc). You may for example prefer bitrate encoding.

Yup! I prefer bitrate encoding instead crf. How to do a 2pass encoding with x265 for achieving a specific size without much loss in quality?.

And do you know the best tweaks for the extra compression techniques tab that which not seen in the x264 encoding.

Just use the slowest x264/x265 presets you can handle. (slow/slower/very slow)

Ok. But how do I do a 2pass encoding like in x264. Are the command line for x265 same as x264?

Very similar (you can run both with the same parameters if you restrict yourself to those which are supported by both).

But not exactly the same. Several parameters are only supported by one of each. Read the help outputs and compare.

And a 2-pass encode is also documented in the help output, at least for x264. Read it. Seriously.

      Two-pass with a bitrate of 1000kbps:
            x264 --pass 1 --bitrate 1000 -o <output> <input>
            x264 --pass 2 --bitrate 1000 -o <output> <input>

This bit is almost identical for x264 and x265. With a few restrictions: x265 supports only Y4M input without several more parameters to explain raw input; and the order and specification of input and output files has a few quirks.
