I'm a very new Motion 5 user, and I am somewhat surprised by the color/alpha rendering and really aggressive antialiasing I am seeing in Motion. (I'm using the latest version: 5.0.6.)
Anyhow, to illustrate the issues I've been seeing, I made a simple test PDF in Illustrator and then exported it in a series of ways, which are illustrated below. (Though things look the same if I make the rectangles directly in Motion with the same colors...)
(1) PDF exported via Illustrator it to a PNG on a solid white background.
(2) I then imported this PDF into Motion and then exported a single frame as a PNG over a transparent background, which I then composited onto a solid white background in Photoshop.
(3) Then, I changed the background in the project properties to "Solid" and exported the a frame that way, thus letting Motion do the compositing onto the white background.
(4) Finally, I tried selecting the "Use Background Color" checkbox in the properties of the PDF media which causes the PDF to be composited onto a white background before any further processing happens in motion.
Note first that the text rendering is VERY VERY fuzzy from Motion vs. Illustrator (or Photoshop, where I added the white overlay text). Is there a way to tell Motion to antialias less aggressively?
Next, note that the alpha-compositing is VERY different when Motion composits the PDF against a white project background (case 3) versus all the other cases. The transparence is much more transparent looking!! This is versus how Photoshop or Illustrator composits 60% opacity against white (cases 1 and 2), or even how Motion does it on a media-specific case (rather than when compositing onto a solid project background), which is case 4. Has anyone else noticed this??
Finally, note how the color rendering intent changes depending on how the compositing was done, which is also pretty surprising.
Is there any way to control any of this? Is this some kind of bug? Or am I not understanding what to expect here? In particular, the fact that Motion seems to to do alpha-compositing wrong on the project background seems really problematic. Color rendering is an iffy thing to expect perfection from, and the soft antialiasing might be a design/aesthetic choice, but the compositing differences don't seem right.
Anyone have any thoughts?
