Hi all, I have just today started getting this dreaded error, i am doing a colour key and motion tracking in 32bpc I have two video layers, one with a rec709 LUT and keylight applied to create a matte and set to invisible, and duplicate layer underneath using the above as an aplha which is visible.
beneath that i have the tracked image with a curves to bring down the brightness i also have 2 adjustment layers above everything one with a blur and another with hue and Sat have been working on this for 2 plus days without any errors, just when i come to export today the error appeared!! typical. thanks for your help
Start by checking your hardware acceleration options and disable them selectively. You likely are simply exhausting resources - several of your effects use GPU features as does H.264 encoding via AME for instance. Also, since the big pile of manure that is Keylight is is involved, you might consider pre-rendering this particular layer. The effect is a buggy mess and a memory hog and can easily bomb any render.
The same thing happened to me, I have a composition with video footage and motion graphics, 2min and the render stops with that error (PF_CMD_SMART_PRERENDER), and my solution was to simply turn off the Plugin (Video Copilot Twitch) and render perfect
