PsyRD & PsyTrellis Question?

[ZooM]

Can someone explain on some example when which settings are used.

I have problems with encoding dark underwater frames (especially on darkblue) and I thought that Psy settings could deliver me better results.

Example is DeepBlue (http://www.imdb.com/title/tt0365109/combined) DVD. Almost everywhere, where the camera is filming dark underwater (not night) there is kind of ringing on my LCD (maybe is my LCD just bad :) ). Even if I encode on bitrates over 4000, the problem is still there.

Psytrellis may produce bad ringing, try to disable it. aslo try to play with AQ

Sounds like you're confusing banding with ringing.

Thanks for replies

Sounds like you're confusing banding with ringing.

Maybe, sorry maybe I misunderstood the definition of ringing :). Here are some examples.
These were coded with following settings with x264 core 67 r1145M d2e1e1c (updated through megui updater), the source is PAL DVD with avg bitrate ~8000. I used your HR Matrix, I didn't know if it makes any sense to use matrix on latest x264 builds. The result looked in my eyes same as other settings with crf16 or crf18, that's why I deleted them, but I could encode some frames with same settings and post it.
Afterwards I realised that it was pretty stupid to use 2pass encoding and matrix :(.
program --pass 2 --bitrate 3000 --stats ".stats" --ref 5 --mixed-refs --bframes 3 --b-adapt 2 --b-pyramid --weightb --direct auto --deblock -1:-1 --subme 7 --trellis 2 --partitions all --8x8dct --me umh --threads auto --thread-input --cqmfile "N:\Matrixes\MPEG-4 AVC Custom Matrices\eqm_avc_hr.cfg" --progress --no-psnr --no-ssim --output "output" "input"

Is there any sense of using original matrix or matrix based on original? If so, what's the way to find out the right one and could I use one created by dgindex?

That's why I asked what can I do with these settings. I googled about it, but at the end I really don't know how, when ... . I would like to understand these settings :). Is there any good manual or thread explaining these settings?

I tried different settings, psytrellis was always "0,0", I understand it as disabled (btw, it's default in megui profiles). Above is one of them, here are some other:

program --crf 18 --ref 5 --mixed-refs --bframes 3 --b-adapt 2 --b-pyramid --weightb --deblock -1:-1 --trellis 2 --partitions all --8x8dct --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input"
program --crf 16 --ref 5 --mixed-refs --bframes 3 --b-adapt 2 --b-pyramid --weightb --deblock -1:-1 --trellis 2 --partitions all --8x8dct --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input"
program --crf 18 --ref 5 --mixed-refs --bframes 3 --b-adapt 2 --b-pyramid --weightb --deblock -1:-1 --trellis 2 --partitions all --8x8dct --me umh --threads auto --thread-input --cqmfile "N:\Matrixes\MPEG-4 AVC Custom Matrices\eqm_v3ehr.xcm" --progress --no-psnr --no-ssim --output "output" "input"

I use CoreAVC, what do you mean with "play with AQ", decoder setting? If so, where can change it?

[Dark Shikari]

That's banding, not ringing.

[ZooM]

Thanks, now I learned something :). I have to learn better Terminology to understand/filter threads to help me myself with this banding problem :(

[LoRd_MuldeR]

Remove that custom matrix and try "--psy-rd 1:0.4" instead. Also "--subme 9" may be worth adding, while "--partitions all" is superfluous (simply remove "--partitions").

Also some dithering before encoding may help to prevent banding...

[Forteen88]

Use AVS-filter gradfun2db(1.8) and ApplyRange() for those frames with banding, if they're difficult to get rid of.

[CruNcher]

there was also some thread here about a new method by manipulating the Streams Video Information to fulrange range and a custom matrix some Decoder seem to render this different and banding seems reduced didn't tried it myself but it sounds nice if it really works ;)
