Very useful and necessary function! It's time to add it to the software!

To use additional devices or software is not always convenient and not very practical. Everything that works with video and audio has this function by default.

+1 Scopes would be yet another feature to make vMix a serious professional tool.

Hi,

Scopes and waveforms require a lot of technical knowledge to get the most use out of them.
I think it would better suit vMix users if instead we automated the tasks usually achieved by analyzing these displays.

Perhaps colour coded systems or similar, for example would it help to have a simple number display showing the current black and white levels as simple numbers?
And maybe a bar graph to show overall balance?

Along these lines, users may not aware that in Input Settings -> Colour Adjust under Black/White stretch there is an Auto button which will automatically
conform the image to close to optimal 0-100 IRE.

Regards,

As mentioned in my post #14 a simple false colour display in PV showing a user defined luminance
band would be a great start for exposure calibration. It would usually be set to 70-80% for skin tones,
similar to the old viewfinder zebra display but the user could also check the black level if set to display 0-5%.

To emulate the primary function of a vectorscope when lining up it would be flagging what pixels are
close to monochrome, R=G=B, ie whites are white, black is black.

thanks

Martin I think whether you use false colour or waveform/vector depends on what you want to use it for.

False colour is great for post work and grading but it's purely for exposure.


The impression I get from a lot of the comments is that people who are switching from traditional switchers to vMix want scopes to colour balance cameras and check colour and exposure from external sources much as they would with a Tektronix.

I know some prosumers may feel like these things are alien hieroglyphics but they're really quite simple and very useful to learn if you do your own editing as well as streaming.

It depends how accurate you want your camera line-up to be.

To ensure you get even light input on each camera across a greyscale you need a waveform to set max white and black but also see whether the grey steps are even and matched across the cameras.

Likewise RGB parades are ok but not as easy to achieve true grey as a vectorscope.

To my knowledge, I have not seen any live broadcasting organisations using the ‘false colour’ technique as part of the exposure and/or colour grading toolkit. Waveform, vectorscope and RGB/YUV Parade continue to be the references used by video professionals and enthusiasts alike.

Quote Admin: “...waveforms and vectorscopes are so technical, users almost need a video engineering degree to understand them.” Having trained numerous high school students in the operation of the Tricaster/ATEM, the scopes do not present a steep learning curve to understand. Concepts are easily grasped and used in every day productions.

Consider perhaps, implementing such a feature request as a paid extra plugin or standard-alone feature to vMix, which could use NDI for connectivity or an application hook using the power of the GPU. That way you can monetise your investment in time and resources, and permit Users to make the choice as to whether they wish to include such a feature into vMix. There are several affordable SDK’s available for inspiration. For example:

Both NewTek IsoRecorder Pro and Connect Pro have waveform/vectorscope tools. (In case one works better for your needs than the other.)

False colour is no good for camera line-up.

Unless I'm reading that wrong, I can't justify $1000 for a small add on to $700 piece of software.


Martin I understand your wish to push the boundaries of new features but vMix is at an 'iPhone moment' in broadcast. It is reliable, flexible and definitely value for money and could become the default mixing/streaming product for the broadcast industry but not without standard broadcast features such as waveforms and vectorscope.
