    @emynach It offers the same GH3 chroma/luma low pass filter matrix - that's all. However, the GH3 uses 8x8 transform as well as 4x4 therefore there are still major quantisation differences - this is because of the two extra 8x8 matrices employed by 8x8 transform in the GH3 encoder which is not found in the GH2's encoder.

    In summary though, its a very good matrix and works rather well as a decent overall setting in the GH2.

    Hi, Just to understant something, what does the gh3onagh2 hack does? does it improve the DR to gh3 level? what are the advantages of this specific hack?

    thanks emy

    @damienmoreau Nice film. Liked how you used music. All very cool.

    "If the gh2 could produce true 2k with it's High big detail" There really is not. It's just resize :)

    @blackspot

    Shhhh, don't tell him that lol

    If it was TRUE 2k people would be making a WAYYYYY bigger deal about it. It's a nice concept and all. I really would like to see his crop zoom stabilize theory. And if your footage looks that bad, that you rely on post stabilizing, it might be time to invest in a tripod or stabilizer instead of trying to manipulate the footage in post. All his methods seem to sacrifice quality to create a false illusion. If the gh2 could produce true 2k with it's High big detail, I would consider canceling my BMCC preorder....not really lol

    "So much more interesting than watching people filming trees with their test footage."

    @dubu49 @orgie18 From chapter 13, verse 4 of the Lumix Decalogue "...and behold those who do not heed the encoded wisdom of the Bush of Death, may they feel the wrath of write failures and macroblocking mud" ;-)

    I haven't noticed any Cluster v8 tests, anyone? Really curious to see how the new 'cinema smooth matrix' compares. ( It's -20c and rarely some sunlight where I am so I haven't been able to run out and film anything worthwhile)

    @IEBA1

    You've been fooled. There is no real 2K video acquisition on GH2 (using spherical lenses). Camera resolves just about 800 vertical lines in to file with 2K resolution. You get better results using AVCHD 1080p. Only good reason to use 2K modified MJPEG codec is to use anamorphic lenses or adapters.

  • orgie18orgie18

    @dubu49 thank for comment. I agree with you, tests with trees and rivers, there are fed up. Make creative guys.

    Hey everyone,

    Long time creeper here on the forums. I guess just around pre-Stalin hack times. Anyway, first of all I would like to say thank you to every single user, poster, creeper, anyone who regularly visits this page and provides the fuel to keep in running because I had never even picked up a camera a year ago today and I just finished my first film short that I am extremely proud considering my absolute zero film background prior to visiting and you all are a big part of that, so thank you. This recognition is long overdue but better late than never I guess.

    Next, I shot this short entirely on the GH2 with a 25mm Panny Leica lens and IntraVenus II. I figured I would post it so everyone could see how it ended up working for me. Any comments, questions or criticisms are, of course, encouraged.

    The quality was light years better when we uploaded to Vimeo but the company had to use the Youtube channel it already had for the drop.

    @gravitate, I'm not "dead set" on MJPEG, but the ability of a core-2 Duo machine to easily edit 2k footage is very nice. Also, I can post-stabilize 2K footage shot with non-OIS lenses, zoom in to lose the edges, and still have a 100% 1080 image. No loss. So instead of shooting 1080 for 720p delivery, I can shoot 2k for 1080p delivery.

    So, faster edit, more capability, easier process, and it didn't cost me tome or money to build a new machine. Because of that, AVCHD is less important to me. AVCHD is critically sharper, but if I'm going to use old glass to soften the image, and dial down the sharpness in the camera, I can just as well shoot with MJPEG and get the other advantages to boot.

    @Matt_GH2, I agree, and seem to be headed that way. Even though I like recording audio in the GH2 with the video, the more I do it I find that an external mixer would help to maximize mic input levels to the camera. So if I've got to use an external box anyway, it might as well be an external recorder. Plus, more of them are doing 4-channel now, so there's just so much more functionality to doing it that way. ambient stereo, lav & shotgun with one record press. :)

    @orgie18 I have to say that is a great video look and edit and the first that made me reply. I am using Intravenus II also...The slo mo is cool too...Artistic and intriguing video to watch. So much more interesting than watching people filming trees with their test footage. This is what we need to show real application of the GH2 hacks and what you can achieve...well done!

  • matt_gh2matt_gh2

    @orgie18 Cool video. Unique style and editing with music. Maybe submit to Heineken for use as possible commercial? Just kidding. They'd never do it...but they should...would definitely increase sales. Very cool. Thanks for posting. Keep rockin!

  • orgie18orgie18

    Intravenus II.

  • herbycamerherbycamer

    @konjow In HBR 25p, it's spanning with sandisk 45mb/s class 10 32Go (with the UHS 1 card, it's freezing cam) and manual lens, shooting landscape with snow falling. I have to try with the 14-140 lens to complete the test. JB

  • konjowkonjow

    @herbycamer did you get cluster x spanning 25p on 32gb 45mbs or 30mbs?

  • matt_gh2matt_gh2

    @driftwood For AN Boom(and other settings) is there any advantage to using MJPEG over AVCHD in terms of image quality.

    @IEBA1 If audio is bad in camera with MJPEG, maybe get a small recorder and microphone, use clapper boare for sync, and your audio quality will be the best possible. In terms of new computers, you should be able to get a decent desktop system for under $1000 that can easily handle AVCHD if you decide to go that route. If you're pretty good at tinkering with computers, you could probably build a "Hackintosh" for even less. Info on that is in this forum and on many other websites too.

    @IEBA1

    and..you are one of the only peple I've ever seen that is dead set on shooting mjpeg. I don't know about you, but any testing I've done with it, the file sizes are 2 to 3x bigger than the average clip of the same length.

  • RenovatioRenovatio

    Thanks Nick! I'm not at home in this period but keep update it's really really important, and you work very hard, and very well :D i'll try Trial 2 as soon as possible! And of course, thinking these are the latest patches, at the end i will ask for the best ever ! For short film...

    A question you heard a thousand time, i know! XD

    Thanks a lot Nick.

  • driftwooddriftwood

    @IEBA1 Can't be changed unfortunately.

    @Renovatio Try out Trial 2, Cluster X Nebula 6 GOP. Soon 12/15 Cluster X trial 4 too.

  • IEBA1IEBA1

    @Gravitate: "What other areas of the gh2 can be improved that have not been done yet?"

    Audio. Especially in the 2K MJPEG mode.

  • RenovatioRenovatio

    Hi guys! Finally 64gb 95MB / s sandisk came at the end! Now the picture is complete: I have the GH2, the Leica 25mm, and the card! I want to make short films, it is important to be versatile and film both environments and faces. But I want as much detail as possible, so I installed the Cluster V7 nebula 6gop sharp II. It 'a good choice? What advice can you give me?

    I also set the main parameters as follows: -2 -2 -2 -2. Recommended something different or can it go?

    Thanks for your attention guys!

  • herbycamerherbycamer

    @driftwood Excuse me nick, you're alright. I used the 45mb/s UHS1 when it freeze. No matters with class 10 45mb/s and 30 mb/s cards. In HBR, everything is alright, spanning too, and it look great at an average of 60Mb/s. Thanks a lot - JB

  • driftwooddriftwood

    @herbycamer 45Mbps extreme cards continue to prove to be problematic. I did HBR test on Extreme HD Video 30Mbps cards (as well as the 64Gb 95 Mbps card) and they were fine on my trees/grill of death scene in my park. Also it passed death charts. I will take a look further and see if we can give way a little.

    Below is a clip with four shots of GH2 B&W Smooth at night using Panny 14-140 lens. The first two were shot a year ago using one of @driftwood settings called SeaQuake in 24H and ISO 12800 (Any of the recent Intra 24h settings will provide the same results). The last two shots are using Cluster X Nebula 6GOP with the same lens, ISO 6400 in 24H and HBR respectively. The point is that with B&W Smooth the high ISO noise turns into a nice grain. Excuse the minor shakes since it was shot handheld. Change quality to 1080p or 720p HD for better results.

  • GravitateMediaGroupGravitateMediaGroup

    it seems that everyone has pretty much agreed that the grain/nosie of intravenus is the best, so from here on out can we just expect it to be that nice on all patches? and can we go back and add it to every patch? lol I am being sarcastic with the last part, but will stand firm by saying sedna + intra grain would be the best patch forever and always.
