Please make Track Matte (and other basic tools) 32bpc
When blending between two layers using a track matte (luma) and exporting to full float EXR - from a 32bpc AE setup - then as soon as the part of the shot where the track matte starts to get used, the file sizes drop heavily - indicating loss of information (I'm creating a loop, so it's not like I'm fading from tons of detail to black - I'm fading from tons of detail to tons of detail). All of my layers inside AE have effects on them that should be good for 32bpc (no warning flags in the effects).
Thanks very much for providing this feedback. Would you able to provide either the project or EXR output for us to take a look at? Are you concluding the loss of quality from the file size/data rate alone or is there also visible degradation of the image?
Thanks so much for any further information,
