color correction broadcast safe

[Shane Ross]

The 3-way color corrector is a great tool. And I’m with them…don’t just slap on the BROADCAST SAFE filter.

Color correcting a show and making it ready for broadcast really requires a lot of skill. Here’s a good article that will get you started:

Hi there.Thank you so much for responding. I read about the vector scope, and i understood that “generally” you don’t want to pass the “color targets” while adjusting color saturation. But in this show, the clips look “all funky”, basically, not real at all, they look colorized. So, my question is: what is legal in the vectorscope??? Again Thank you so much.

It has never been between you and them
it has always been you and god

Never above 100 IRE for the whites, and not below 0 IRE for the blacks. And the colors are measured on the vectorscope, and are not to exceed 100.

if you want to avoid getting crazy with this difficult task
try my ‘mastering’ plugin – just drop it onto the whole (nested) sequence with it’s default settings.
see documentation & demo at https://www.1z1.at/plugins/

but be aware, that it’s likely that your very colorized footage will loose colors in areas
that are very bright and heavy saturated at the same time.
keep in mind: 100%red + 100%green + 100%blue = 100%white (which has no saturation per definition!!!)

good luck,
kurt

I submitted a bug to apple. Here’s a link to the image which I added to my report. The point is- the FCP ‘Broadcast Safe’ filter does not seem to perform as advertised.
————————————————————————
BUG DESCRIPTION SENT TO APPLE:
Final cut Pro (v5.0.3 for sure – perhaps others) does not provide video clamping to the 100% mark – actually appears to be rather ineffective regardless of threshold/settings. See the enclosed image for a comparison of a frame before and after the filter is applied.

Additionally, it appears the behavior of the filter is not to simply squash the excessively bright pixels to a legal level, but rather it compresses values of all of the pixels near what would be the ‘whites’ range of the color corrector down towards black – which effectively reduces the dynamic range of the image in the brighter areas – instead of simply removing the influence of pixels which are too bright.

Anybody else have any thoughts about how best to make use of ‘Broadcast Safe’?

That’s a bummer. Did you ever get rectification for this?
