I’d wait until the next release but deadlines :confused:

Here is the error report (OSX). Tried different resolutions, export formats and disconnecting HDMI and all USB devices. Still no luck.

This should have been fixed in 4.12 - the matinee recording features didn’t work on Metal in 4.11. If you want to record from 4.11 you will have to open the Editor from the command-line and add “-opengl” as an additional command-line argument to force OpenGL rendering in order to record i.e.:
/Path/To/UE4Editor.app/Contents/MacOS/UE4Editor /Path/To/YourProject.uproject -opengl

(replacing /Path/To with the actual path on your Mac to UE4Editor and replacing /Path/To/YourProject with the path to your .uproject file)
