Hi Ondrej, we can't give any specific but the bigger the RAM and the faster the CPU makes a great machine for exporting projects on VMFX.
This really needs to be addressed. What is creating the issue where the audio does not line up with the video. Preview does not reflect properly the music track alignment with the slides after export even with zero delay set on all slides. I assume it is an issue with the additional power needed for the video capture but I could be wrong.
