  1. What is the best way to deal with potential banding from the A7s and from other cameras that produce 8-bit files? Here is an example of banding that appeared in A7s footage after pushing it in post. Thanks!
  2. Hello everyone, I just installed Magic Lantern on my 5D3 last week. I have been doing some test shoots with it, but I keep coming up with this vertical banding. I have looked all over the place to find a solution, but can't seem to pin one down. I don't know if this is a problem within my camera, or the program I used to process the RAW image to CinemaDNG. Any suggestions would be incredibly helpful. Thanks!
  3. Hello,   I have been experiencing a problem every so often with my relatively new GH2 in which I will see this strange red line going across the frame.  Please see the attached image for a visual reference (in this still the line is on the upper third of the image if you are having trouble finding it).   This line moves about and varies in width and position, depending on how the camera moves.  The problem seems to occur out of nowhere, although I haven't seen it enough times to say that for certain, and seems to also go away on it's own.  It hasn't wrecked any sho
  4. Just back from two days in a row of shooting. Some shots had some really serious banding or flickering. I don't understand it at all. Also because other shots under the same circumstances haven't the same problems. Thank god I have enough shots to create the vid.  Because I'm still learning how to shoot with all the settings on my GH3 I set everything on automatic except the diaphragm - A modus. Other settings; MOV, 24 p - 50 Mbps (for Europe), Contrast -5, Sharpness -5, Color -3, Noise reduction -4.  I used the one point (correct name) setting, for measuring the light. 
  5. I've uploaded some test footage from the new Panasonic GH3.    The first portion of the video contains fairly even lighting with tests from f2.8/ISO 200 - f16/ISO 6400. The second portion introduces a hot spot via a desk lamp. Test are from f4.0/ISO 200 - f22/ISO 6400.    Gradation looks very good in the bright areas of the footage. Blacks are fairly consistent throughout. ISO 200 - 800 appears damn fine, as far as noise is concerned. ISO 1600 fairly good and easily workable.  ISO 3200 is usable. 6400 is useless.   https://vimeo.com/58314941
  6. Hello all I've got my hands on a GH2 and I was planning on shooting some footage of various LCD screens. This will be custom software in use at specific locations so I can't use Camtasia or similar. Whilst running some tests, I've noticed some severe banding on certain screens. All the screens so far have been 60hz. I've shot in PAL 25fps and NTSC 30fps at both 1/50 and 1/60 (and other shutter speeds) but I can't lose the banding. The frequency of the bands changes but no shutter speed loses it completely. All other settings are either neutral or off i.e. standard mod
  7. Here is my test I did today.  There are a few notes to be aware of:   1) There is moire evident when set at 0 (roof of the pavilion).  At -5 there is none, although the compression of youtube introduces moire. 2) Excessive sharpening in post is akin to sharpening in-camera by re-introducing moire.  Not only that but it also exacerbates banding as well.  The last shot of the sunset, you can see a sort of "pulsing" wave above the sun.  This is not present in either the 0 or -5 setting, although you can see some banding in the 0 setting. 3) There is a lot of nois
  8. My crusade against color banding on the GH2 continues. The Flowmotion hack (v2.02) minimizes banding as well or better than any hack I have tried, but I still get unusable shots from time to time. Today, I used FCP7's log and transfer to import a single clip with banding issues. Then I used 5DtoRGB to process the same problem clip and exported every possible combination to see if there was a magical setting that would stop color banding altogether. There isn't. But somewhat unsurprisingly, ProRes 4444 / Full Range / ITU-R BT.601 seems to be a significant improvement. Here are the setti
  9. Can anyone tell me what is causing the horizontal banding at the top of the wall outside of the bedroom in these two shots? I was testing a steady cam today and noticed my Gh2 (24p, flowmotion hack) was showing these horizontal bands along the top. Yes, I've had trouble with the already much discussed High ISO/Underexposed area (mine shows up as low as 400 ISO) and thought I would try the same work around...shoot at a shutter speed of 30. Didn't help, the first photo was with a SS of 30, the second is with a SS of 50. The banding looks different, but is clearly there on both. Part of m
  10. [b]Dear Andrew, Dear All,[/b] I am one of these fans visiting EOSHD.com every day, a couple of times and checking every update. So finally after purchasing my GH2 I decided to register to the EOSHD forum. Just finished university and now have some time to film with my brand new GH2. I am living in Germany and bought my GH2 from a Germany onlineshop. The serial number starts with WE1HA. Now as I have rad the EOSHD GH2 shooters guide and went out filming I discovered one really sad GH2 bug which I found out is well known. The horizontal darker line ind footage shot over ISO1000 and underex
