Frequently Asked Questions

Yes, outdated or incompatible graphics drivers can interfere with hardware acceleration in your browser or the Clipchamp application, potentially leading to visual display errors like darkened timeline previews.
Where can I find my Clipchamp version number for a support ticket?
