Hi, I ran into a very weird problem with exporting from AE CC (2015 188.8.131.52), and thought I'd see if anyone else has had this issue/can discover why its happening! I found a "workaround" that solved the problem for me, but which could potentially cause problems for other people.
I have a series of masks in a composition. When I render the comp using the Media Encoder, the mask looks correct:
But when I try to render as an MOV directly through after effects ("Best Settings", "Lossless") the mask "shifts" for a few frames
After a lot of hair-pulling, I finally discovered that the mask renders correctly when the "Motion Blur" setting is turned to "Off" - here is the setting in its default position. Note that I have NO motion blurs on any of my layers, anywhere in my comp - so this setting would not solve the issue for someone who needed motion blur turned on:
Anyone else run into this issue, or come up with a different solution?
