Can't export video or img sequence from Matinee?

Hi,
I have been to trying with no success to export video from Matinee.
I have my Director set up with the right camera.
Matinee is set to launch on play in the details tab and in the Level Blueprint.

When I hit the Create Movie button I get a save error… something along the lines of …
‘G:/…/…/…/UNREAL_PROJECTS/…/Saved/Autosaves/Game/Maps/UEDPCMinimal_Default.umap’
Not sure if this is indicative of the problem?

Any help would be much appreciated!

Thankyou!

Are you using that autosave file right now? If you are try to resave it as you would a normal level, into Content/Maps folder and try again.

Thankyou Jacky!
Yes that seems to have sorted it.
