Frage von DeejayMD:


Moinsen! \u003cbr /\u003e\u003cbr /\u003e I was with my GH2 to highlight the last Kaeltewelle in the Alps on the way. Fucking cold, but good! One day I had above about-25C and fierce headwind. Nevertheless, I tried a couple of snapshots capture. \u003cbr /\u003e When my views are uncomfortable then Rush and strong banding noticed in the sky: \u003cbr /\u003e\u003cbr /\u003e http://dl.dropbox.com/u/42147919/GH2_Noise.MTS \u003cbr /\u003e\u003cimg alt=\

The first thing I would have done: The whole time with original firmware tries. ;-)

If I (change the firmware) have not done this in the "warm" in Hamburg ... \u003cbr /\u003e\u003cbr /\u003e No, there's the top was just too cold for such a joke. \u003cbr /\u003e\u003cbr /\u003e The hack was so Easily (with its advantages) in the plush valley. \u003cbr /\u003e\u003cbr /\u003e Best regards \u003cbr /\u003e\u003cbr /\u003e MD

Antwort von domain:

Nostalgic style is of course a cardinal error and the standard automatic exposure synonymous with this recording. \u003cbr /\u003e If something in the art, it's all about targeted purely at the positive exposure and other processing in the post. \u003cbr /\u003e Winter recordings require special Claims that because over the snow at all times not fit into the gray card scheme.

Antwort von DeejayMD:

Automatics were in this recording is not in play. I had just put the wrong WB (sunglasses). \u003cbr /\u003e\u003cbr /\u003e I lad today evening times a recording of about 3000m high, which looks very good (warmer temps). \u003cbr /\u003e\u003cbr /\u003e Best regards \u003cbr /\u003e\u003cbr /\u003e MD

Antwort von DeejayMD:

Hhm, I `s with TsRemux trimmed. Perhaps the fact incur the problems? With Media Player Classic and Media Player (Win XP) but it works. VLC shows me in black bid. \u003cbr /\u003e Does anyone else a program that allows a trim the MTS files without having to recalculate? \u003cbr /\u003e\u003cbr /\u003e The original file is about 1 min long and with about 600MB just too big. \u003cbr /\u003e\u003cbr /\u003e Best regards \u003cbr /\u003e\u003cbr /\u003e MD

From Vegas 10 times out now MainConceptAVC one file, encoded in two Durchgaengen with max. 30 million bit / s and an average of 24 million bits / s rausgerendert.

I'm beginning February twisted in Munich, about -15 degrees ... also chopped (EOSHD vanilla patch), 44MBit, 24 B / s, sluggish adjust (after EOSHD "My Film 1" - would have to seek it out, these are the typical -2, -2.0, -2, or something similar) .. . \u003cbr /\u003e The only problem was ghosting when viewing the material in the cold weather immediately after the shooting, because the crystals of the LCD did not like cold weather. I was naturally worried that these streaks are synonymous in the later material ... luckily they were not. The image was flawless ... \u003cbr /\u003e\u003cbr /\u003e I can well imagine, however, that at even colder temperatures, the sensor may eventually no longer, but is estimated to be the case whenever the cam ... \u003cbr /\u003e\u003cbr /\u003e Lots of love, \u003cbr /\u003e Sinarius

Antwort von handiro:

I fear there are more sensitive than cmos ccd. I have received from beetle synonymous with the hpx250 rush and I complained to panasonic .... pointless. \u003cbr /\u003e\u003cbr /\u003e but as I have to adduce evidence nozeit I'll probably look around for ccd.

Antwort von DeejayMD:

Oh, oh, I hope that is not a permanent condition. After viewing another recording, I realized that Rush is synonymous here, and especially to see banding. If synonymous not so strong, but that seems to be generally of the brighter image (100MB): \u003cbr /\u003e\u003cbr /\u003e http://dl.dropbox.com/u/42147919/Schwenk_GH2.mp4 \u003cbr /\u003e\u003cimg alt=\

Base: Firmware 1.0 \u003cbr /\u003e\u003cbr /\u003e - Nostalgic \u003cbr /\u003e - 2, -2, -2, 0 \u003cbr /\u003e - Custom WB \u003cbr /\u003e\u003cbr /\u003e Cinema/24p in mode 24h with Driftwwod AQ2 `s @ 100Mbit GOP1 \u003cbr /\u003e\u003cbr /\u003e Lens: Lumix 14-140mm @ 60mm approximately (Alpine pan). \u003cbr /\u003e Aperture: roundabout 9-10 \u003cbr /\u003e\u003cbr /\u003e Heliopan Vario ND approximately at level 9, so that a shutter of 1/50 could be achieved. \u003cbr /\u003e\u003cbr /\u003e I hope I forgot nothing.

Antwort von WoWu:

It looks as though mainly the Blue sensors have received too little light. \u003cbr /\u003e That is probably either have been much einwenig ND or the hack is good for nothing. Not to mention that the white balance of something is wrong, but that can be corrected if necessary. \u003cbr /\u003e Now that I have not the first time heard that the Hack (for some reason always synonymous) is to rush, I would put the Kares only once again back to the initial state and (sometimes synonymous with no ND) make a "home turn." \u003cbr /\u003e I bet everything is ok then. After that you can sometimes reconstruct piece by piece to see what it is. As I said, for me there are two possibilities. \u003cbr /\u003e But the camera only translated once again into the original state

Antwort von Axel:

WoWu is right. This Rush the "proof of detail" is. I use a hack (currently vanilla) only when I know I'm only lowlight. I know this phenomenon synonymous. I can explain it, but I can reassure you: play 1.0 or 1.1 on it (can even be permanently on a particular card, you will of course not only formatierst "All Delete" choose), and the rush is gone. In the Hellen could "soft" better to be banding (heaven). Evidence can not I, but I do it, and I have no more banding.

Antwort von WoWu:

My advice in relation to the hack is so that the internal signaling within the GoP on IBBB is her one and then the 2.und3. B-frame has taken and used again for an I and a B farm has, which have been signaled not at all. \u003cbr /\u003e Now, the decoder searches for the contents of two non-existing B-frames in order to completely reproduce the image. \u003cbr /\u003e The following I and B frames are pretty much him no preference as long as there are noIDEs because not signaled. \u003cbr /\u003e But so be it. Just as long as 100 Mbit / s make it as unhappy, sorry for the beautiful pictures.

Antwort von pilskopf:

Actually, the hack is supposed to prevent or improve just banding. I can do tomorrow once daylight Videos with ISO 160 and am curious how it rustles the material, so I did earlier times lowlight shots made with ISO 640 and see nothing bad, horny but the stability of the material in the color shift, so I find a lot better than under normal firmware.

Antwort von Axel:

Yes, these tests do still. It must be that something rustles. I took a winter field, three of approximately thirty shots, and the brown crumb strong rushes. Should you be not that you reproduce it. Reports then.
