Onboard Waveform Please!

Jim and team if you are even still listening to these posts, I beg you:

Please include some sort of basic waveform monitor that can be toggled on/off with an actual physical button. I like zebra lines in the LCD but they don't give you the same sense for how things are blowing out on the top like a simple waveform. I have been using the Panasonic 7" LCD on Varicam shoots that has the waveform and it is a godsend especially if you don't have a dedicated D.I.T. or even the rental budget (or spare hands) for a vectorscope/waveform monitor.

Oh yeah, also no matter what, seriously, dedicated dials for the audio channel levels and the mixer bus. It has to be at least as good at the DVX!

Thanks!

Oh crap, I almost forgot. If you make a waveform overlay that is assignable to video outputs by the camera menu system, I will do a backflip.

Great post. I'd love a camera that could show me a friggin waveform/histogram something! I mean, how hard should that be?
 
I posted this a while ago but I still would like to see this feature:

A false color exposure aid would be great as well. Sort of like how a thermal camera displays degress, but in f-stops instead. Would make it very easy to read the exposure values of the scene. Especially on a small screen where a waveform or histrogram might be to detailed.
Something like this:

the original
thermal.jpg

The exposure mode. Each tone represents a difference of approx. 1 stop.

Failing that, would it be possible to have user assignable colours to two adjustable level zebras - I'm constantly confusing which zebra is which on my DVX100! I'd like to set my higher level to something like red to warn of clipping, and my lower one to say green or blue to indicate exposure on faces.
 
Waveform etc

Camera monitoring GUI includes focus, framing and exposure (level) assist.

Th GUI shows up on the EVF video output and the LCD monitor video output.

HDMI and HD-SDI monitor outputs are clean feeds, i.e. video but no GUI overlay.

As always, specifications subject to change ... suggestions always welcome.
 
..Well, as you asked for sugestions...
It would be nice to have the option to have the GUI fed out to the HDMI and HD-SDI feeds too (preferably individually settable).

For example if using an external HDMI monitor, I can forsee the GUI beeing visible there as a handy option.


Umm.. "EVF video output". I haven't heard about that. What type of signal is it? :huh:

Optically zooming the image inside the EVF might be useful, so that the screen can vary in apparent size

Maybe to divide the screen into different "windows" where say you could have a zoomed in detail available while seeing the full image or have the screen split between no color adjustment and a personalized color curve

The ability to save viewing preferences and give it a personalized name so that you could pick what "tools" will be visible and perhaps you simply push a small button and it rolls through your selected favorite settings. This way a person that likes waveform will keep alternating between a waveform and a regular view, and another guy will set it to alternate between a closeup and a regular view etc.
 
I worked a lot with the Accuscene viewfinder with the F900, and I love the "colour code" of the system... maybe we can have something simillar.
But in other hand... With the varicam I use A LOT (and I mean A LOT) the Y-GET mode...
you know.... the camera reads the pixel of the middle of the cross of the viewfinder, and gives you the level in %
Perfect for quick exposure combined with a gray card.
 
Stuart is possible to output an HDSDI 2K 422 or 444 and record at 4k REDCODE raw at the same time?... and is possible to output with time code impressed?

thanks!
 
the accuscene way of exposure:
OFF:
exposure01.jpg


ON:
exposure02.jpg


Blue/purple areas are underexposed, yellow/orange areas are overexposed, Gray is corrected exposed.
It really works pretty well, I love to work with, and looks very simillar of what anders propose.

[FONT=Arial, Helvetica, sans-serif]For convenience, the AccuScene™ Exposure System also adds a narrow band of salmon pink colour at 41 IRE (18% according to REC709) to allow simple lighting adjustments when using an 18% reflectance calibration card in the desired position and lighting so that camera ND filters, exposure and lighting can be adjusted until the card appears pink in the AccuScene™ display[/FONT]
[FONT=Arial, Helvetica, sans-serif]The AccuScene™ is calibated to show the 100 IRE transition (bright yellow to pale orange) at 700mV nominal Y (luma) level after the Y offset has been adjusted to show the 0.2 IRE transition (black to indigo) at 0mV nominal Y(luma) level. HD cameras often add an offset of about 3 IRE (21mV) to both levels at their viewfinder output port[/FONT]
