that's great Vitaliy, i guess many GH2 users would have "better/perfect" HDMI output.
But it's o.k. you define what is to do as next step.
Thanks !

Thanks Vitaliy.
We can still hope to connect this little bomb to external recorder.
Hope this change can be done by a future hack.

I wrote this post in reply to someone who was asking to contribute to the hdmi hack. As I thought it was promptly removed and some good reason that I list below. What I think I wrote below is still valid for the hdmi hack brigade.


I think it is the third time I saw a post like this and I don't think it will live very long. I know that it would be very nice to get clean hdmi and perhaps the only solution to the next level, I mean 422 and 10 bit output. But as had been said so many times it will come. I think if you took just a little time to understand the man (interview in 43rumors) for example you would see somebody less than motivated by money. It is not the typical blogger/forum administrator which are more like a sales persons getting a commission on each sales. Because what you are saying in between the lines, is let us pay him so that the time he would use to tweak the avchd codec would be use for the hdmi. A lot of people have already contributed to the hack and it would be fare for them. In the end with this theory we could set up an auction part where everybody would bid for a certain fuction, hey $ 50 for hdmi, no I give $ 100 for lcd marking/masking etc. I think with the continuous harassment (it is feeling more and more this way) you might get the complete opposite effect. As I said above I am really keen to see the hdmi output but I will wait, I think it is a form of respect to VK for what he has already done.

+1 for HDMI, i looking foward for the Sound Devices PIX 220, with proper XLR audio recording and quicktime, teorically can interlace footage from GH2, with booth i can have a nice AF100 kicker arse.

@xenogears I have been using sound devices gear for the last 12 years. I love the Pix220 but it sucks that its compression is Apple ProRes and AvidHDx. I am a windows adobe user and would have to convert my footage every time.

@Vitaliy_Kiselev I dream about more lighting and scripting skills. :-)

How soon will the hack improve lighting and script? Those sound like great features.

ProRes encoder is not free.

I hope I don't hurt forum rules if I repeat something here (posted under GH2 film modes too):

I found something interesting today when playing with HDMI-recoding with and without recording to SD at the same time. We all know that plain HDMI-Recording is more contrasty and clips white and black massively.
But when looking at my shots I found that it is actually full range (0-255) instead of video-range (16-235). While there was still some clipping with a very contrasty scene, there was useable detail in those super-white and super-black areas on my waveform.
It seems that a grading system which is able to handle a full-range signal could use such footage very well and make better use of the 8 bits Panasonic is allowing us.

What do you think?

I knew that. I wanted to figure out in which way it is inaccurate and if you can make some use of it…
