View Full Version : intensity curves in mixes
Richard,
in addition to an intensity sub master on each mix, it would be good to be able to assign a user definable curve to each mix.
For instance I currently have 9 domestic CRT tv's each with a mix feeding to them. When I spread an image over all of them and fade it up, the fade across all TVs is different.
Currently I'm having to use 9 layers set to "use layer mix" and set curves on each layer using my console.
If I was able to set a curve on the mix in catalyst this would make life easier.

with a random bunch of domestic tvs- thats more than just a mix curve-
there will be different gamma response on each one

Yes true, but it would still help

can you put up a grey scale and colour chart on each tv - at full intensity
then take a decent photograph of each screen
this will give you some idea of the gamma differences

To take Richard's method a bit further, I will actually point a Flat camera at each screen/TV and then use a scope to adjust the settings of the media server output. This has worked wonders on LED walls, different video projectors, and anything else which might pop up.

it needs a gamma curve for every mix-
i dont think intensity curve would work for the tvs - intensity curve presumes linear intensity across the colour output
