Expose To The Right (ETTR)
@LPowell, it seems that there are two different expose to the right understandings. To me expose to the right was always about perhaps overexposing visually (using a histogram as a reference so not to clip the highlights) but recording more info and…

Expose To The Right (ETTR)
Well it certainly does as far as exposure is concerned. With digital just like with slide you expose for the highlights and fill for shadows. With negative you expose for shadows and develop for your highlights.

Expose To The Right (ETTR)
@ Ptchaw Canon 5D mark II: sensor size 36x24mm Super35 (most common film format in motion pictures): roughly 22x19mm, full size never used. Difference in area roughly x3.5 times. Yes, wide use of "Full" size sensor for video production is …

@soapey It works fine for jpegs, as ETTR is not about recording format but about the way the sensor works. @Ptchaw Human eye depth of field in the dark is hardly "huge". While it's true that in the bright day light human eye is roughl…

...the camera would also need to record a low bitrate metadata stream indicating the normalization factor used in each macroblock. Naturally, this would require modifications to existing JPEG and AVCHD codecs, which are long overdue for other reason…

They just released new version (Neat Video 3) it has GPU acceleration and also optimized code, so it is apparently 2x as fast even without GPU.

@itimjim Nothing is free. ETTR works because of the linear nature of the sensor. When you increase the ISO of a digital sensor you are not really increasing the ISO, you are increasing electrical gain. Increasing the gain = lowering the dynamic ran…

Panning with GH2
Been discussed recently, pls search the forum

Pro: Direct testing requests
Tried to do so. After inserting it into a camera Camera says: SD card error. Format?

And finally, the Canon 5d fires back against the GH.
And how is this filter going to fix binning and line skipping?

I would not compare Color FInesse with Colorista directly. They are different in what they do to the image.

@Nino_Ilacqua Will you tell us how well it performs in a sunlight and otherwise outdoors whenever you get a chance?

Truthfulness of short GOP superiority claims
I guess is the time to reveal the sources of the footage. Most of you chose clip B as a 3GOP, clip A as a 6GOP and a clip C as a 12GOP. One of you thought that all of the clips are the same footage and only one of you were almost right. Congratulati…

Is it worth getting Color Checker Passport?
So, x-rite color checker passport bundled software does not allow for creation of an icc/icm color profiles. One can use a target that comes with color checker to create an icc profile with a professional color profiling solutions (Ks of $). What co…

GH2 Stutter/Judder/Strobe issues discussion
@dalefpf try two things: first find in this topic my suggestion on panning rates and follow it. Do you still see strobing motion in your footage? Do a review on a powerful enough computer (plays fine on a 2009 MBP, also on a 2.66 Quad core duo Windo…

Effect of converting 30 fps to 25 or 24fps by software?
Cineform Neoscene will not convert anything unless it is a 60i footage (59.97). In all other cases it conforms (it has some pitch adjustment though). Please search the forum. There was a recent discussion on frame rate conversion.

@jimtreats this is most likely a tolerance to account for expansion/contraction due to the temperature.

GH2 Stutter/Judder/Strobe issues discussion
@Dalefpf There are certain charts published by ASC regarding the judder avoidance. These charts rely pretty much on a "7 seconds rule" In a pinch for a 24fps footage shot at 180º shutter (1/50th of a second for GH2, I guess) the panning ra…

@cosimo_bullo is MJPEG at 30 fps? If so it will have less jello than 24 fps AVCHD...

There is a very interesting hardware solution for rolling shutter and temporal aliasing (wheels turning backwards) they do say that they need clean video out of the camera in order to synch. http://www.tessive.com/home/time-filter

@madcat You did not miss anything, you are correct regarding the pipeline. People either do not understand or trying purposefully misrepresent the test.

@madact You are not entirely correct. If they hit the download they will get an equivalent of a bluray level h264 (@ 50mbps). As one of the 3GOP preset developers have admitted they do not see motion issues with bluray reproduced movies (which do us…

GH2 film modes
@ptchaw While shooting in B&W and then grading for doutone might be easier, shooting in color would afford more tonality control in post. For example I would use an adjustment layer 1 on top of adjustment layer 2 on top of my footage. In adjustm…

@kae Of course you would want to see original MTS. This way you would be able to run it through a parser and say "of course this clip is better than that, as it has lower GOP" The best I can do for you is to give you is an i-frame cineform…

@bdegazio One of the reasons I was anxiously waiting for the @Vitaliy_Kiselev hack of GH2 was that very same problem you have described - pulsation in the shadows corresponding to the length of the GOP (well back then I did not know of the GOP lengt…
