Kodi, Sonarr and X265

[JohnnyJazz]

I use Sonarr to automatically download files into my Kodi libraries. Everything was fine until recently I noticed a drop in quality. In the setup I selected 720p as it is a good compromise between size and quality. But I found out the problem was with the encoding as it seems more and more files are now encoded using the X265 standard.

X265 is advertised as producing much smaller files at allegedly similar or better quality than X264. The X265 files are actually much smaller but when I watch them with Kodi I found that even in 1080p the quality doesn't match a 720p in the old standard. I was told it was because I need to update my softwares but I can't find any Kodi's update related to this problem.

Alternatively I could exclude X265 files from Sonarr but I looked in Sonarr setup and can't find where I could select or exclude the format in which I want / don't want the files encoded.

Any advise ?

It's a total disaster. Now 90% of Sonarr's download are in X265, which means first that I have to check and probably download again everything that I've downloaded for the past two weeks and then I've to stop using Sonarr until I've found a fix for that problem.
