Preset of tune x264

[BDHDLIGHT]

Good evening

I encode all my movies that I have on Blu-ray in x264.
I always use the HandBrake movie tune that gives deblock=1:-1:-1 on all my movies, except for my Blu-ray animated films where I use the animation tune.
I see many other encoders that use deblock=1:-2:-2 and deblock=1:-3:-3 for the same movies. So, I wonder if I made a mistake using deblock =1:-1:-1

I also specify that I never use the HandBrake tune grain.
I don’t know if this has an impact on my encodings.

You didn't make a mistake. -1:-1 is optimal for x264 and you'll gain very little if at all by going lower.

The key settings in x264 are preset veryslow, tune film, and profile level, typically 4.1 for 1080p.

Beyond that, you could use aq-mode 3, adjust the keyframe interval, lookahead, etc.

Tune Grain tends to increase the bitrate quite dramatically for a given CRF value.

AVC's deblocking is too strong by default, the lower value should be preferred when targeting higher quality.
But it's not like your videos are ruined, the difference is subtle.

Tune animation is generally considered not good for high quality encode.

Thank you all for your responses.

Hello

I have the impression that with deblock=1:-3:-3, the textures are better preserved than with deblock=1:-1:-1

The image appears sharper with deblock=1:-3:-3 than with deblock=1:-1:-1

[GeoffreyA]

-3:-3 is popular. If you feel it is sharper, no harm in using it. I prefer -1:-1.

[BDHDLIGHT]

I’m hesitating to really use it because I read that it could have a negative impact on the video.

My goal is above all to have the most faithful video to the original Blu-ray.

[Z2697]

If result videos don't have very noticeable blocks, then it's OK.
Higher bitrate generally have less blocking artifact.

Which psy-rd should I use with deblock=1:-3:-3 ?

[microchip8]

Which psy-rd should I use with deblock=1:-3:-3 ?

psy-rd is independent of deblock. Use psy-rd=1.0,0.15

[BDHDLIGHT]

It seemed to me that with deblock=1:-3:-3, the Psy-Trellis absolutely had to stay at 0.00
