Gamut errors, what are they?
Ok, heres the thing,
I have supplied probably over 50 tvcs in the last couple of years for a particular client for broadcast. They are graphical tvcs all made in After Effects. Very quick to do and I deliver to a company via FTP who farm out the tvc to the stations that the agency have booked with.
I have used the same process from the beginning and never been rejected once. My trick for legal colours is an adjustment layer with levels filter and pulling in the outputs by a few 5 or so points.
All good. Works a charm, everyone is happy. I have seen this on scopes in the past and that trick works.
Now out of the blue I get a rejection on two tvcs saying they have gamut errors on the last frame.
The thing is in these tvcs are part of a batch of ten all with the same end frame. But two have errors.
So what gives??
What is a gamut error exactly? This is not a chroma luminance issue is it?
How do I fix it? Particularly as it has not shown up on previous tvcs with the same frame.
Any ideas are much appreciated.
