How would you encode this? Grain & Noisy

Postby Bauzi » Sat Sep 11, 2010 6:44 am

Heyho!

I already requested a large file upload for this video, but there is something that just doesn't get out of my head: The possibility that there could be a better way to encode this video. As the perfectionist that I am, I just have to ask for some encoding advice on this video. :uhoh:

Okay this is the situation:
24fps @ 1920x1080
The video has grain in it. A lot. I want to save this details of the image, because it's just the visual style of it. However I want it to have a nice qualilty/filesize ratio.

Here is a screenshot of the video:

As you can see: There is one heavy grain textures. This one is static. It doesn't move at all. There is also a light grain effect on every scene with about 7% setting.

I got the best results in zarxGUI 1.31 with the following settings:
Mode: Constant quality @ 19
Preset: Slow
Tune: Grain

Deblocking: -3
Variance AQ: 0.75
Psy-RD: 1.38
Trellis: Off

Has anybody some nice suggestions? :(

First of all, update zarxgui to version 1.32.
Then, increase the constant quality to 20 or 21 (it shouldn't hurt yet since you're dealing with 1080p content), change the preset to veryslow, increase the psy-trellis to like 0.8, go to the command line section, add:
Code: Select all
--fgo 15 --qcomp 0.55

create a BAT and encode from that. Should have some improvements.

This is awesome! I get a third of the file size with my settings.

Thank you very much *_*

Not sure if you are aware, but you don't need to create a bat in order for it to use the extra commandline arguments.

I used to think so, but then I once read that you said they didn't get used otherwise. I probably misunderstood that one time, but oh well, both ways work regardless.

I like .bat files. shutdown -s and I can go to work or to sleep while I make multiple encodes at once =)

I would give a nice string for you but :LAZYMODO: and mirko gave you the most important stuff already. That and I'd need a sample of your clip and some idea of how small you want it. Last size squeezing attempt I got a 380M video down to 107M with no visible quality loss, and that was without FGO or the other fancy patches around now.
