Premiere 22 Vorschaufenster und Export in Grün, mit horizontalen Streifen : (

[MaWiHaBe]

Eine halbe Ewigkeit mit Premiere 11 zufrieden gewesen.

Nun also Premiere 22 - Leider bin ich noch nicht begeister.

Importierte mp4 erscheinen im Vorschaufenster und nach dem Export (satt) grün, mit horizontalen Streifen. Das gleiche Programm mit der gleichen Lizenz auf einem Zweitgerät installiert funktioniert tadellos.

Woran kann es liegen, was kann ich verändern?

Herzlichen Dank für konstruktive Tipps

Based on lots of other messages, that is a video driver problem

Do not count on Windows to be fully up to date when it comes to device drivers
Go to the vendor site to be sure you have an updated driver for your graphic adapter
nVidia Driver Downloads https://www.nvidia.com/Download/index.aspx?lang=en-us
-for all Adobe programs use the STUDIO driver, not the GAMING driver
If you have a laptop you MAY also need to check for a laptop specific nVidia driver
-SOME laptops require an approved driver from the laptop company, not nVidia
AMD/ATI Driver https://www.amd.com/en/support
Intel https://downloadcenter.intel.com/product/211969/Intel-HD-Graphics-Family
There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version

NVIDIA Studio Drivers are drivers that are specially designed for creators.
They are released on a regular, longer cadence that matches major app launches,
typically every month. This way your PC is ready every time your favorite app
updates, but your work is not disrupted often. These drivers are extensively
tested against the top creative apps to ensure that your system won’t have any
issues. New updates unlock performance boosts and sometimes new features in
creative apps, providing artists, creators and 3D developers the best performance
and reliability. (my thought... Studio driver is better than Gaming driver)

Green means there is an issue with the gpu.

Thank you very much for the tips.

The driver search turned up nothing. The file is an mp4. Premiere 11 shows it and handles it flawlessly. Premiere 22 colors it green. The tip about the GPU would explain why Premiere 22 doesn't do what it's supposed to do on my slightly older Acer Aspire. Thanks - I'll take care of it tomorrow.
