Again, the final bitrate is not an evidence of good or bad quality.

For example, if you encode a totally black clip, a bitrate almost equal to 0 is largely sufficient to obtain a perfect quality. But if you encode a movie where all images are totally different from each other, 13.0 Mbps is certainly not enough to have a decent quality.

Don't trust the guides and other noise found on the internet. There is NO good or bad bitrate. Only good or bad quality. And if you look closely to your movie and you cannot see the difference with the original, that means that the quality is excellent, regardless of the bitrate.

Also, don't forget that the bitrates recommended on many sites are for DVD-Fab or similar bad encoders. If you use x264 (especially with a slow preset) you can certainly divide it by 2 and 3 and still obtain a better quality.

Do not be obsessed by the bitrate. It doesn't means much in term of quality.

BTW, I have also seen that you have enabled the "grain" tuning. IMO, it's a bad idea. It will probably degrade the final quality, unless you give a very high bitrate. IMO, you should only use the "animation" tune when you encode a classic animated movie like an old Disney or Tex Avery, with large flat areas (not modern CGI). Other tune options should be avoided, unless you know exactly what you are doing.
