Some videos showing artifacts while playing
#1
I am getting some strange behavior and I think it may be the files format but am not sure what to be looking for. The videos will play back but there are off and on spots of artifacts all over the screen. I have not had this issue while playing them through vlc. It seems to be a codec issue but not sure what to try.

I am using the October Monthly. Windows 8 Pro 64

Here are the media info files for the videos I seem to be having issues with. Thanks for any help[/quote]

This is an known issue with intel HD graphics particularly sandy bridge/haswell when hardware acceleration is enabled(dxva). When you play in VLC, it is probably not using hardware acceleration. If you enable it, you would notice the same behaviour. You can search for it and you would find plenty of threads here and also in intel forums.
