In Speedgrade, my waveform display and above all my RGB Parade show multiple horizontal black lines.
I haven't seen scopes behave like this in other programs like Resolve, FCP X, or Premiere. Could this be a bug or is it just the way the scopes behave in Speedgrade?

Yep. Did you notice how they tend to match the numbers on the sides? They're a design feature, a graticule sort of thing.

Wrong. Speedgrade is improperly scaling the values for display on the scope post-adjustment.

Unsure of any solution but it's definitely not a design feature, it's just a crappy looking scope.

Not seeing this as an improper scaling problem, as I think of scaling as looking at the total top-to-bottom DR, is that wrong?

I don't get any difference on my clips between the shown scopes in Sg, PrPro, or Ae ... but then, I don't have an external scope system either.

On my system, all the little black ... bars? ... seem to line up precisely with the gradient markers on the sides. Which has the effect of giving essentially a reference line across them ...

But to be clear, always looking to learn. Love new data ...
