Recommended settings for X265

[Cazz]

Hi
I running VidCoder (Have also try handbrake that is build on) and trying to find a good settings for X265
That settings I have now is very nice but it take to long to convert my files, a 30 min video take over 2 hours.

I have run this settings before with nice quality and nice speed but did have some problem with some files and I did find the problem.
I did have to low level in video encoding so I did change it to automatic and now it take a long time.

I know if I want to have a very good quality it going to take time but it feel I have select to much quality??

My settings is very simple. That I recording is from my HDTV and it create a video file.
I then run VidCoder with not so much change settings from default.

Sizeing I have Automatic and Max height of 720 (I do not need to have the video in full HD)

Detelecine = Off
Deinterlace = Decomb, Default, Default
Denoise = hqdn3d, Medium
Chroma smooth = Off
Sharpen = Off
Colorspace = Off

Video codec = H.265
Framerate = Same as source
Quality = 22 RF
Tune = None
Profile = Automatic
Level = Automatic
More settings = "ref=5:bframes=5"

Audio mixdown to Stereo (Most that i recording is already stereo)

/UPDATE

I notice that I can run with GPU when I use AMD VCE.
Now it take less then 4 min but the size is around 3 times bigger then I use CPU instead?

Try using a faster preset with x265.

For AMD VCE... If you're using bitrate based encoding specify a lower bitrate (that directly effects the file size). If you're using quality based encoding specify a lower quality to get a smaller file size.

I've had good luck with "fast" preset; read an article somwhere, apparently that's the sweet spot

This is the best guide I've seen, and I've seen it linked to by knowledgeable users ...it says it's for Anime but much modern anime has a lot of CGI so the settings are pretty portable. I've seen a bunch of live action/CGI video using their settings and it looks pretty damn good.
