Topaz Video 1.7.1 cannot open any video files on Windows 11. MP4 and MOV files both fail with “Error loading 1 file”. VLC and Windows Media Player open the same files successfully. NVIDIA RTX 5070 drivers are current and HEVC Video Extensions are installed. Log shows:
Failed to open codec through avcodec_open2()
Could not open reader
Unable to load video
Try disabling the hardware decode option in the Preferences Panel under the Processing section.
If that does not work, then grab the logs and send to the support team at help@topazlabs.com for a deeper review.
