Thanks Rick and Andy, as usual I follow the CV-Live. But I do not use the chat, for many reasons.
Roughly six years ago, I was in contact with RE:Vision and I produced a tutorial for them about the UVW channel from C4D to Ae. Pretty much at that time I indroduced this plug in to many other people, as it is a big help. It might be true for the Youveelizer, but I haven’t tested it so far.
As Rick mentioned Anti Alias is not an option for Data based image channels. I had the impression that point was a little bit blurry after too much input in the talk. So here my point of view to the theme.
These are numbers and each single pixel can carry only one value (RGB). In the moment these values do not arrive “healthy” at the plug in, the effect will be compromised.
I highly suggest to go with 32bit/c (channel) and not with anything lower to work. Please note that the “.hri” format is a 32 bit/p format. It means 32bit per pixel, it is a 4*8bit/c. A big no to use in professional environment for this kind of work. It is in ever second book described wrongly. OpenEXR is the most efficient format to my knowledge which is as well Industry standard since a while.
Avoid any non linear files (No gamma, no color profile), dithering-methods, or compression to this. Yes, to have a compression method one that is not without loss, will destroy this data as well.
All the best
