I don't remember this happening back in the standard def days (Vegas 7 era), but in 12, 13 and my editing partner's V16, it pixilates badly during the transition itself.

It happens with 4k and 1080 footage (video or still images) and every codec I render to...mainly Cineform, .mp4 (any flavor) and even uncompressed. GPU acceleration on or off...makes no difference. I tried different GPU drivers, updated and rolled back...no difference. Dissolves and zooms work fine...my stuff is mainly mini-doc oriented, so I tend not to use "glitzy" transitions. I edit in a 4k timeline and deliver in 1080p HD.

I have a Radeon RX460 4GB, his is a 480 with 8GB. Intel CPU (mine is i7 6700k, his is 7700k). Tried Intel 530 onboard GFX...same problem. I even tried it on my old XP machine with V12; no joy, but Sateesh's old 3D LE 32bit plug in did work when spinning on the vertical axis. Go figure.

However: the New Blue 3D Flip transition he has on his machine works fine! No pixilation.

I rendered the spin transition in my ancient version of Boris Red and it also renders perfectly. The issue appears to be within the Vegas transition itself....never updated/fixed over several generations. I'm on Win 7, so I haven't tried the V17 demo, as it's supposed to be for Win 10 only.

Has anyone gotten this simple transition to render without pixilation?
