Waveform-Parade confusion (screenshot)

by crashing do you mean you think your reds are crushed?
The above scopes don’t show anything being crushed.

Seth –

First of all, if this is camera original footage then I can say with certainty that the camera is in need of a black balance. Your red channel is sitting at baseline where it should be but red and blue are lifted substantially. Also blue is very noisy. If you were to lower the blacks in the red and blue channels then you’re white bal will be very much plus red. The scope doesn’t lie; that’s not a pretty picture it’s depicting.

As for the monochrome display, that’s Luma, which in low pass mode, will show you the brightness of the picture displayed in IRE or milivolts or percent or what have you. It’s useful for establishing where the exposure window and gamma curve should be but can’t help you with color.

Tektronix has some very helpful tutorials and white papers online. You might go to their site and check them out.

The Tektronix white paper “A Guide to Using Waveform Monitors as Artistic Tools in Color Grading” is a really good one. Not a barrel of laughs, but it’s about 100 pages on how to interpret what a waveform monitor, parade display, or vectorscope tells you about the image. You have to register with Tek to get the free paper, but they won’t bother you with spam:

The front porch is too wide to be legal.

Meet you in the breezeway, then. Oh, wait a minute, I’m blanking.
