@yskunto Hi fellow! I´ll try to make my tests with a faster SDHD one hehehebut anyways , this patch from humpman was holding up ALOT more than any other patch that haven,t seen before!! even with a "theorically" so slow SDHC card!! :) Next time, I´ll do some test on a tripod to see what happens.
@humpman Hello! One question only, Must we to overwrite the existing tables in the original patch? I mean [Patch6] and [Patch7] whith the new ones? Both tables at the same time? Thanks!! Asier.
Relax guys :) I known about this problem, it occurs on high detailed scenes or death chart, also it can start to collapse not immediately but after several sec or minutes. This is why i noted "Not for day by day using". I just wanted to know how fast and on what type of scene you'll get those distortion. Cause of this distortion is coefficients between i and p scaling table numbers. I just set those tables on edge of the top, so if there little wind will blow, it fall.
Use this tables below, and tell me if you can see difference in quality, and distortion.
Here it is!

Hello humpman! I´ve been doing some test in both NTSC and PAL with your 68Mbps patch and its VERY nice!! Never the less, I´ve found some distorsion when I record a scene with ALOT of detail and it´s lit by the sun. I´ve to add that I´m not using a VERY fast SDHC card (It´s a SANDISK 16GB class 4 15MB/s... ). I´m uploading a sample clip with some distorsion in it to let you analize it and see what happened, if you don´t mind! ;-) Anyways, I´ve oppened in Streamparser and, as far as I can see, It looks like the program thinks and says it´s OK!! THANKS FOR YOUR HARD WORK FELLOW!!! Cheers... Asier.
Hi there humpman!! I just installed your 8 of June patch and VERY impressed with the quality! :-) I´ve made a few night tests only so far but the bit rate, even in low light conditions, overpasses 60 Mbps!! WOW Tomorrow I´ll be testing this NICE patch of yours in daylight conditions, and report what happens! Cheers and THANKS for you GREAT effort! Asier.
@frullaccia yes, i just wanted find good balane, but i can't seat two extremes on one chair. If i get nice 3200 iso, then i get bad low ISO's and so vice versa. So i will stay with previous table style. @yskunto there is 91000000 max bitrate number for PAL, and 98000000 for NTSC(24.000), so i would like to separate them.
Of course, I'm talking about the GH2 codec. But the main concept is not far from what we should consider about GH1 camera.
@humpman. Following our previous conversation.
You are right about the fact that the first numbers of the scaling table determine how detailed the picture is.
Furthermore they are concerned with other parameters and are important for the efficiency of the codec.
Using low numbers will produce a very sharp image. Sharp images are difficult to be managed, because every little problem of the camera appears to be magnified through the detailed scene of the shot.
It is like having a good hifi amplifier. If the whole musical system is not well balanced, every single problem will be clearly audible.
The real problem with low numbers in GOP 1 patches is flickering. If we use GOP 2 or GOP 3, with their P and B frames, then the P frames overall will be critical, because the codec hardly support that level of detail. P and B frames in our GH codec are not conceived for that.
I have install your NTSC/PAL hybrid setting that you post before to my just arrived GH1. At a glance, I would say the quality is very good. As usual, when switch between NTSC/PAL, one should turn off the camera after and better to format the SD card once the camera is turned on.
Will see if it is spanning later on. Thank you for your hard work!Here is the settings for NTSC. 68 Mbps. 24.000 fps after deinterlace. I changed a P-scale matrix here to get better image quality on high ISO's. I'm not sure on stability of it, so can't recommend it for day by day usage yet. Also, there is two new patches, "2997i to 2400" and "2997i to 2397". Download third one setb.ini please.
I have a GH1 on the way. I could help to test @humpman patch. About the GH1 60i mode diagonal rain. Does it means to overcome the problem is to go native 24p and sacrifice reliability or stay with a QPmin=19 like what @apefos found and sacrifice detailization?
Last time I mixed your QP setting to @Lpowel peak reliability patch in i60. I perceived no diagonal rain even with QPmin=0 on Death Chart. I will retest.It looks like you're new here. If you want to get involved, click one of these buttons!
