DJV 3 - Feature request - (video) scopes, histogram and (audio) meter

[aberkl]

It would be beneficial to have a number of "Analysis Tools" in DJV when it comes to image comparison (color wise and other).

I could imagine having another separate window "Analysis Tools" (like "Secondary Window") hosting

• Color Picker (as already existing)
• Waveform monitor (What are my image levels, are the blacks crushed?)
• Vectorscope (Which color and saturation?)
• Histogram (Distribution of levels)
• Audio Meters (is there audio? Is it clipping?)

A separate window would allow to fiddle with colors and directly observing the result.

This should be post-color processing (and audio volume/mute) to analyze the effects of a LUT or other color manipulation.

Also, it would be fantastic if the input of the of the "Analysis Tools" would sit behind the compare logic. Thus, it would be possible to toggle A/B, or "Compare Horizontal to see 2 sources side-by-side in "analysis".
