    Just did a quick test; Mode S, 720, 100 in yellow, Auto iso on

    And still got the effect in grass?? . It was sunny.

    Sorry feel really dumb..

    Afc is on But don' t know what you mean with IS ? Can't find it..?

  • mpgxsvcdmpgxsvcd

    @Jaapsb

    Post a sample so we can see what is going on. Just post it to youtube or something. IS is image stabilization. With the 14-42mm it is controlled in the menu.

    Please don't kill me for these questions but i am not able to find out what does stand for:

    GOP ETC

    As you can check i am new in this bussines. Sorry for my english I am from Spain.

  • sanzadezsanzadez

    @Vittowar, please refer to the FAQs at the top of the page when researching such.

    from the FAQ: With ETC mode turned off, the GH2 uses a 14-megapixel (4976 x 2800 pixel) area of the image sensor covering its entire width, downsampling it to an output of 1920 x 1080 or 1280 x 720 pixels. With ETC mode turned on, the camera uses a 1920 x 1080 or 1280 x 720 pixel area of the center of the image sensor, mapping each pixel 1:1 from the sensor to the output video. ETC mode gives you a narrower field of view - 2.6 or 3.9 times narrower, a picture that's slightly less sharp, has less aliasing, less of a rolling shutter effect (“jello”), and is much noisier for the same ISO setting - equivalent to raising the ISO setting by 2 and 2/3 stops.

    From Wikipedia: The GOP is a group of successive pictures within a coded video stream. Each coded video stream consists of successive GOPs.

    A GOP can contain the following picture types: I-picture or I-frame (intra coded picture) - reference picture, which represents a fixed image and which is independent of other picture types. Each GOP begins with this type of picture. P-picture or P-frame (predictive coded picture) - contains motion-compensated difference information from the preceding I- or P-frame. B-picture or B-frame (bidirectionally predictive coded picture) - contains difference information from the preceding and following I- or P-frame within a GOP.

    Hope those help

    @sanzadez

    ETC mode makes the camera appear to have more of a rolling shutter effect (“jello”) and not less. The affect is not decreased because the readout of the camera is still 1/120th even for the smaller cropped sensor area. The affect is actually the same. However, the reduced field of view makes the jello affect more pronounced.

  • sanzadezsanzadez

    @mpgxsvcd, the ETC part was copy and pasted directly from the FAQ, not my words

  • mpgxsvcdmpgxsvcd

    @sanzadez

    They become your words when you state them. :) We will just have to see about changing the FAQ then. Won't we?

    MPGXSVCD: "@Jaapsb Post a sample so we can see what is going on. Just post it to youtube or something. IS is image stabilization. With the 14-42mm it is controlled in the menu."

    Ok, I had the image stabilization alsways on mode 1, can this be the reason of jitter ? It's to dark outside now, to try again. Here is my test of today; mode S, 720, 100, autoiso, lens 14-42 on 14, sanity 3.1 on it, IS mode 1.

    Just a small test with moving the cam. It's already much better, but not what it needs to be I think?

    If someone wants to look for me ? Thanks in advance for the great help already!

    24H MODE VS HBR MODE QUESTION SURROUNDING 25P:

    I've installed the @driftwood AQuamotion hack v2 which has blown me away. I have shot test footage today in every video setting and received an average bitrate of around 90mbps in its highest quality mode (24H). However, this shoots at a frame rate of 24fps (or more accurately 23.98).

    I am based in the UK so I favour 25fps shooting (PAL).

    Shooting in High Bitrate mode (HBR) allows me to shoot at this desired frame rate (PAL 25p). However, I have noticed that the bitrate is significantly lower in this mode when shooting with the Aquamotion v2 hack. My tests (shooting the same water fountain) averaged at around the 60mbps mark as opposed to 90.

    My question is this: how can I up the bitrate in the HBR mode which shoots at my desired 25p? I can't see any options for this in the PTool program, only 24H, 24L, FSH/SH and FH/H. I presume the HBR setting adopts the bit rate from one of these? If so, which one exactly?

    I also read that in the 25p mode, it's not "real" 25p. If this is true can somebody explain what's happening here please?

    If it is the case that it's not "true" 25p, would you recommend I actually shoot in 24H after all and convert to 25p Prores for editing?

    I'd love to know your thoughts on the matter.

    Many thanks.

  • mozesmozes

    @Jaapsb i have it some times.
    Did you have I.DYNAMIC on?
    Also in the profile that you use, set it all to -2 -2 -2 -2
    And try it again... must be better then...

  • JaapsbJaapsb

    Yes, I had it on this time,

    But I think it was also when switched off, because it was there when filming in ia mode.

  • SpeldosaSpeldosa

    So, I've hacked my GH2 with the EOSHD Unified patch (88 Mbit). Everything seems fine in e camera. The ISO 12800 option is available and I'm only allowed to film for 22 minutes on my 16GB card. However, when I import my movies to my Mac (I've tried both iMovie and Adobe Bridge), the filesizes are as big as before and I really can't see any difference between the old and the new movies. How can I double check that my material actually is comming out at 88 Mbit?

  • dualrealitydualreality

    @Speldosa the easiest way to do this is to play the file in the latest version of VLC Media Player, hit ctrl+i (or cmd+i on a mac) or click Window (in the menu) then Media Information. Click 'Statistics' and look at what the 'input bitrate reads at'.

  • KeithLommelKeithLommel

    @dualreality: AQuamotion was developed for firmware version 1.0, which did not include 25p or 30p HBR modes. If you want to use 25p, you should look at the newer settings that are designed for firmware version 1.1 (i.e. PTools 3.64d).

    That said, you'll be disappointed to learn that because of the way HBR is encoded in the camera, it has been difficult for settings developers to achieve the same level of image quality and bit rates in these HBR modes as we are accustomed to in 24p, which remains the highest quality mode for film production. However, if you absolutely need 25p, there are settings that will get you much better quality than stock firmware (just not quite as good as 24p). @Driftwood's latest efforts (Orion, Sedna, etc.) seem to be focused primarily on maximizing quality on the 24p settings, which is now quite excellent indeed, but some 25p shooters have complained that quality in that area is not as high, so you may wish to explore some other well-regarded settings, such as Sanity by @Ralph_B and Cake by @Balazar.

  • balazerbalazer

    mpgxsvcd, I'm not sure how you're concluding that ETC has more jello than normal mode. I definitely see less jello in ETC, independent of the angle of view.

  • mozesmozes

    @jaapb in IA mode its also on, ALWAYS, it collors yellow when its getting active when shooting

  • JaapsbJaapsb

    @mozes, but must the dynamic be on or off ??

    I am going to try again today, with all new tips..

  • SpeldosaSpeldosa

    @dualreality: Thanks, I will check it out. However, even if it would say for exameple 88 Mbit, I could not believe this since the file size isn't bigger than before.

  • mpgxsvcdmpgxsvcd

    @balazer

    This has to be shown to be understood. I will try to make a video showing you what I mean.

  • SpeldosaSpeldosa

    @dualreality: VLC says that it can't play the file because it is an ICOD-file :S

  • neko30neko30

    hi all,

    i'm a new GH2 user...i initially installed a couple patches (sedna) with no problems. but lately, i've been trying to install new patches (v4d, v4b)...but everytime i load new patch into camera, the camera says i have 3 hours and 3 mins recording time--on a 32 gb card.

    something is wrong, right?

    does anybody have any idea of what may be going on? i'm installing same way originally...but now seem to be having problems.

    could it have to do with the re-naming process? the first patch i loaded, i re-named GH2__V12.bin. but once i started with the additional patches, i didn't maintain order and named then GH2_V14.bin, GH2_V17.bin, etc.

    thanks for any advice. goro

  • mozesmozes

    @Jaapsb i dont no, i have tried it.
    In some cases its beautiful, but most off the time its just to much.

  • InjuredGodsInjuredGods

    Hello everyone just a quick question. I have hacked my GH2 using the no adverse settings hack and am using a 16 GB Sandisk Extreme 30 MB/s. When I take video I am able to watch it back on the camera no problem, but when I transfer it to my computer it will play for a little bit and then just stop playing. I use VLC to watch the videos and I see that the timebar at the bottom is still moving, but there is no movement in the picture. Does that mean that the hack is too detailed for my computer's hardware and is causing the hangup? Any help would be appreciated. Thank you!

  • peternappeternap

    VLC is too slow for a lot of these settings although I never had any trouble with no adverse affects.

    Try Splash Lite. It's free and works pretty well.

  • trialbojtrialboj

    Hi all, can i upgrade my gh2 firmware to 1,1 ( http://panasonic.net/avc/lumix/systemcamera/gms/gh2/index.html ) without loosing the warranty ?
