Any video file I important ends up super blurry and pixelated with the colors extending across the screen. This is the new 300 Build for Vegas Pro 21.0. This has occurred since I updated. Please please please help
If it is AVC you can try "enable legacy AVC decoding" in preferences, file io. If HEVC you can try experimental HEVC decoding in the same place. Be sure to restart VEGAS after making the change.
Otherwise uninstall 300 and reinstall 208. You can download it from here.
