    @Ralph_B Sorry I am a bit confused by the above. Are you saying 95% of the time you should use the inbuilt GH2 WB presets like Sunny, Cloudy, Tungsten etc for when the environment matches?

    Or are you saying create 2 custom presets yourself, one for indoor with +5 Magenta and one for outdoor with +2 Magenta and use these two only?

  • Ralph_BRalph_B

    @lmackreath

    Good question. Here's what I've been using... First, I never use auto white balance - the camera can be fooled too easily into giving you inaccurate color. 95% of the time I find the preset white balances work just fine. The other 5% I'll manually adjust the color temperature up or down to suit.

    For color correction, you need different settings for indoor and daylight. Indoor: +5 Magenta. Daylight: +2 Magenta. The nice thing is the camera remembers these settings independently for each preset white balance. For Cloudy and Shade, use +2 Magenta, since these are basically daylight settings.

    I found these settings produce extremely neutral color. For example, I have a friend who has a Canon 1D mark IV, and we frequently do video shoots together. If we both set our cameras to the preset white balances, the hues of the colors come out identical. (There are differences in the gamma curves, but that's another story.)

    How do people have their white balance set when using Sanity?...I use Auto White Balance but have it customised in the colour chart to two steps toward yellow (on the left) and 1 step down toward Magenta. I have been told this compensates for the general green cast that the GH2 gives off, and warms the auto white balance preset slightly to remove the grey and neutral colour tones.

    Another Sanity 5.1 creation

    I see it, and I repeat, that's normal for the GH2. Sometimes at ISO 160 you get these faint, flashing horizontal bars. It has nothing to do with Sanity. You'll see them on the HDMI output, as well. I have no idea what causes them. Sometimes they're there, most times they're not. One thing you might try is to shoot in the range of ISO 200 to 400. I never did formal testing, but I don't recall seeing the bars there.

    On further thought, what might cause the bars is having a significant area of blown highlights in the frame. It feels like this is a sensor issue.

    Here's a better upload. You can see noise in the blacks when the HD is turned on. No other noise in the shadows in the rest of this footage.

  • Brother12Brother12

    It's odd, because there is no noise in the shadows in similar shots. I will try Neat Video though.

  • tetakpataktetakpatak

    @Brother12 you can get rid of the noise in the shadows by using Neat Video in post, great plug-in

  • Ralph_BRalph_B

    @Brother12

    Impossible to see what you're talking about because the noise from the youtube compression obliterates everything else. The GH2 always has some noise in the deep shadows, even at ISO 160. This is normal (even though we may not like it).

  • Brother12Brother12

    Hi There.

    First time poster, long time reader. I have attached a clip with some obvious digital noise. Running Sanity 5.0, ISO 160, lumix 14mm (not sure of the f-stop, probably high) and 24p L

    I occasionally get noise like this in my shots. What is causing it? Is it the light refracting off the mist? It looks like something more complicated than that to me though.

    Also, there is some artifacting from the compression, but try to use your imaginations.

  • lmackreathlmackreath

    @Alienhead I use a Light Craft Workshop 49mm ND fader and use a a ring for it to fit on the 46mm filter of the Leica. This fader cost me £60 and have never noticed any issues with sharpness or colour casting. I have watched numerous videos comparing my cheaper fader to both the Tiffen version (around £110) and the Singh Ray models (around £200 plus!) and couldn't really see the difference in sharpness at the wide to mid range.

    I used to have a Polaroid cheapy fader but again to be honest I thought the quality from that was very acceptable as well.

    I would say for run and gun shooting the variable fader is much easy to use that having to constantly change filters. All I do now is dial in my required shutter speed (1/40) and my aperture for the shot and then press record. I then simply control the exposure with the fader.

  • AlienheadAlienhead

    @lmackreath

    And you used a fader ND filter or individual ones? What brand? I've got a Polaroid Fader filter, it's been fine for video with the 35mm Nikon lens I've been using, but it's not the quality of the lumix 25mm. However I've been looking into getting the lumix and I'm not sure how much quality I'd be compromising with a fader filter versus individual filters (which I'd rather not have to deal with). My sense is that the extra softening of the image might only be noticeable with stills. But then I also have to add a step-down ring to use my 52mm fader.

    @Ralph_B thanks for your feedback and thanks for your patch! it was my first wedding, and was for friends so the pressure was on!

    Grading needs a lot of work, and the length is a bit too long...but all in all happy with the results!

    keep up the good work!

  • Ralph_BRalph_B

    @lmackreath

    Just had time to watch your video. Fabulous work!

  • lmackreathlmackreath

    @Alienhead 99% of it was shot with the lumix leica 25mm 1.4, with some wide shots using the kit 14-42

  • Ralph_BRalph_B

    @soundgh2

    Awesome!

  • soundgh2soundgh2

    @Ralph_B 1 year ongoing doco currently being shot on V5.1 on Gh2 by chum on purely (video looking apparently) Pana lenses - 14-42 kit, 20 1.7 and 100-300 (yes really) , and looking super (he don't give a fuck as as his day job, he films expensive shit for other people with pretty endless budgets) BBC and Ch4 UK loving the sizzler and commenting on it's great look - refreshing, great stuff!

  • AlienheadAlienhead

    Great job, what sort of lenses and kit did you use?

  • lmackreathlmackreath

    A wedding I shot this month on Sanity 5.1. I shot over 6 hours of footage over 3 SD cards over one day and didn't have ANY issues. Here is the 22 min edit!

  • Ralph_BRalph_B

    @soundgh2

    Thanks for the report. Sanity is now at the point where you can just set it and forget it.

  • soundgh2soundgh2

    Shot with Sanity 5.1 at Glastonbury all week on 2 cams - no problems at all and looked great.

  • Ralph_BRalph_B

    @darrbee

    Don't know since I don't have a GX1. Perhaps someone else can answer your question. But I would tend to think not, because the parameters for the GX1 are probably different from the GH2.

  • darrbeedarrbee

    Can I use PTool with Sanity 5.1 parameters on GX1?

  • tetakpataktetakpatak

    @MendalFly GH2's image looks great in its native 160 ISO and then in 1EV steps (320, 640, 1280)

  • MendalFlyMendalFly

    Hey guys,

    Just show C roll for a local TV show. While I was super happy with the performance of the hack, I noticed at ISO 800 footage looked a little rough. What ISO do you guys generally stop at using this hack?
