Color Bars with intact pluge
So while the “insert color bars” function is still in development, does anybody have a good tip for putting color bars into a sequence without clipping the -5% part of the pluge?
I’m outputting to 10-bit RGB DPX with a 64-940 scaling LUT in the output LUT.

Make sure that “Colorspace conversion uses” is set to “unscaled full range data.” This setting is found in the “Video Monitoring” section of the “Project” in “Config.” That may be the problem.

Yes, but if you do that you’ll have to have a separate external limiter.
The better answer is “insert edit after layoff”

So I’m monitoring full-range values (with the output LUT), and I’m not laying off to tape so an insert edit isn’t really an option… It certainly clips before getting to the monitoring settings…

What’s your deliverable format?

Hi,
h
to my knowledge any Lut, which is applied in the config-tab, will affect only the 10Bit-values.
BM please correct me if I’m wrong.
Every part from a legal scaled video outside of the 64-940 range will be expanded to levels outside the full range (0-1023). You can recover this levels with the correctors but not with a Lut (in my experience not with a Lut generated in resolve with a corrector-node).
So the only way to display a full pluge is to import it in a rgb-format that contains a legal ranged signal.Regards

Sorry, I have to complete my last sentance : or to correct it in a node to legal range. Assuming you are displaying full range.

Thanks Knut,
That’s what my testing seems to suggest – adjusting color bars with the grading controls seems imprecise to me, and bringing in RGB DPX files with legal values for the bars should work, except that it can’t have the same LUT applied that is being applied to the rest of the footage… I suppose I can do the output LUTs by track…
Hopefully when the color bar tool is enabled it works with all these possibilities…
