Revolution and ColorSync?

[Josh Mellicker]

I set the filename of a player in Revolution to a Quicktime movie.

The top image here:

http://revcoders.org/color-issue/

is how the movie appears in Revolution, the bottom image is how it  
appears in Quicktime Player. You can see the top image looked faded  
and “washed out”.

It seems that QT Player is applying some kind of ColorSync or other  
color management profile adjustment where Revolution is not?

The codec of the movie is ProRes422, Apple’s new codec. No other codec  
I tested exhibits this behavior, they look the same in QT Player and  
in a player in Revolution.

I just wondered if anyone had run into movies displaying differently  
in Revolution and how they dealt with it.

Thanks for any illumination!_______________________________________________

Hi Josh,

Apparently, QT Player takes some gamma value into account, while the  
Rev player object can't do that. I don't think there is any solution  
for this other than using a different codec (which won't take any  
gamma values into account at all).

In Revolution, one may set a gamma value, but it applies to PNG images  
only, AFAIK.

Are you sure that your player object doesn't have any inks or  
blendLevel set?

Hi Mark,

No, it doesn't have inks or blend, other codecs match up perfectly.

Thanks for your reply, I think this is something we'll just have to  
live with.

As far as I'm aware, Rev is entirely unaware of ColorSync/ICC profiles  
when displaying videos or images. :-(
