Levels different between AE 7 MAC and FCP

[Zander]

ok, well for starters, are they darker on your computer monitor or on a production monitor, fcp and a.e use there own visual settings, ive come across similer things, (not from fcp to a.e.) but from an image of a document to fcp, and in an output monitor they were identicle

I am doing some testing and discovered that a render from FCP
is different than a render from AE. Same file in both apps.
Rendered to the same file flavor and codec.
Bring those two files into a PC and they do not match.
Tried on two different PC’s

The same two files match in AE and FCP on the MAC.
Seems like the MAC is adding set-up somewhere??
But why would a rendered file have a different gamma.
You can see on the scopes in FCP that the AE rendered files
have more black but they look the same.
Tried different set-ups in AE but that does not seem to
be the problem.
My client wanted PhotoJPEG. I saw that a 100% JPEG is
RGB but it 75% it is YUV. I am trying an RGB render in FCP
and a 75% render in AE to see if that is what is going on???

One thing is that on the Mac Apple natively supports the Panasonic DVCPro and DVCProHD codecs. This might give them a leg up handling colorspace issues. I don’t have an answer to your problem, except to say that since the US is a 7.5 IRE black and most DV and HD signals are 0 IRE Black, we will continue to have color space issues affecting blacks, and depending on the OS version, platform, QT version, video card or other factors, we will struggle trying to make our ins and outs match.

In this digital age, which is sold to consumers as the promised land, there are as many potholes as NTSC. Actually, in some ways the simplicity of analog will be missed.

I sort of miss it already…

Mike: Is it possible that you’re using Decklink hardware on your Windows or Mac system? There’s a widely reported gamma issue/conflict related to the Blackmagic/Apple codecs. Maybe they solved the issue, but you’re not using the latest drivers? I am making too many assumptions just in case it helps 🙂

No I am just using a 17″ Powerbook. The output is rendered files.
Thanks

I had the same problem until I realised the FCP sequence settings were set to yuv instead of rgb. When I switched to rgb everything returned to normal.
