[SOLVED] Video playback glitches on fresh install.

Hello everyone, I am having issues with glitchy video playback. The issue is hard to describe so I will post a screenshot. It usually happens when I skip around the file or when a scene changes. I am using nvidia drivers. I thought it might have something to do with ffmpeg or mpv, so I installed the git version of both from the AUR and still have the same issue. I also installed VLC and it has the same problem. I then followed the guide to enable video acceleration with vdpau, but this seemed to have no effect at all. My computer can definitely handle HD video as windows has no issues. If anybody has any suggestions I would appreciate it.

What is the video source?  File? DVD? Streaming on-line?

Sorry, should have specified. Video source is always a local file. Most content plays fine except the really HD ones which are around 50gb. It's strange that I have this issue in Linux but not in Windows.

EDIT: More detail, streaming 4k content from youtube has no issues.

Re: [SOLVED] Video playback glitches on fresh install.

If  these files are uncompressed, you need data transfer rates from the drive on the order of 200 MBytes/sec to sustain 10 bit 1920 x 1080 at  60 f/s (interleaved).
This laptop only gets 65MBytes/sec.  An SSD would not have any issues -- SATA 2 is good for 300MB/s. 

If they are compressed, then the bottleneck is the decompression.  What are your processor cores doing? Or is your system using a GPU for decompression?

Re: [SOLVED] Video playback glitches on fresh install.

Thank you for your replies ewaller. I actually managed to solve the problem myself! For future reference to anybody else who has this issue. My external drives were formatted as NTFS. Apparently Arch isn't too good at reading NTFS filesystems by default. Installing ntfs-3g solved my problem entirely.

I'll bet the data rates are significantly higher too

Oh yeah, very much so. That should have been my first hint
