Bug écran noir Monitor Premiere Pro

Try turning off Hardware encoding in the Video tab of the export settings.

Try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.

Never easy to troubleshoot premiere problems from a distance so please tell us your system specs: OS version, Premiere version, amount of RAM, Hardware specs including graphics card and if you have any 3rd party plugins installed for Premiere... Also, sequence settings and clip properties can also help. Although you can throw almost any format into premiere, some formats can be problematic, particularly on an underpowered system.
