Wishlist: Graph presets for different source media types

[pjotrek-b]

Different source media show different artefacts by having different abnormalities in different graphs. For example, Digibeta dropouts can be seen in the BRNG graph, whereas that graph is quite irrelevant for other sources.

Therefore, if one could define presets which graphs to display/hide, it would make it very easy and inuitive for (especially new) users, getting the information needed to do the best analysis.

For example, those defined presets could be offered as dropdown-list (or something else).

Not difficult to implement but I need a list of presets.

We already have one preset (current default), but I'll send up more.

[pjotrek-b]

Just from the top of my head, a few examples:

Digibeta dropouts: Y, Diffs, Sat

Unclean cuts: Y, Diffs, MSEf

Letter-/Pillarbox detection: (for aspect ratio mix) Y, Diffs, CropW, CropH

Do you find BRNG more effective than SATMAX for digibeta dropouts?

[pjotrek-b]

I'm currently at home, where I don't have test material for this. As far as I remember an the tests I've done at work, all Digibeta dropouts I've checked showed clear peaks in BRNG, which the vectorscope clearly confirmed.

[pjotrek-b]

I've checked again at work, and my memory was wrong: They definitely show up more clearly on SATMAX. There's a different kind of artefact on Digibeta that stands out in BRNG, but is also clearly visible in SATHIGH.

That artefact looks as follows:

So I revoke everything I've said before about BRNG for Digibeta dropouts. SAT MIN/MAX it is. ;)

[dericed]

SATHIGH would only show a digibeta dropout is it was so severe it caused more than 10 percent of pixels to show illegal color, which is one bad digibeta dropout. SATMAX will show small and large digibeta dropouts clearly. SATMIN is somewhat silly to have since there will almost always be at least one pixel with no saturation. A SATMIN above zero would be rare, maybe in computer animation.
