Picture gradually pixilates then suddenly rectifies itself.

Hi there, this is my first post on this forum so be gentle. I am by no means clued up with this kinda thing so please forgive my ignorance. I'm sure there's a simple setting that needs to be changed but I have no idea what it might be. My problem is that as I watch a movie (I don't think format has anything to do with it) the picture progressively deteriorates and pixilates over the space of say 5-8 seconds then suddenly snaps back to being at it's optimal resolution. It does this on loop for the entire duration of the movie. I have searched online but have found no answers to this problem.

Any ideas as to what I need to do? Any help greatly appreciated.

Thanks

Have you looked at this thread (https://forum.videolan.org/viewtopic.php?f=12&t=117809? It is a long one, but there might be some similarity to your problem?

That effect can be seen on very poorly encoded videos. It cleans up when it reaches a keyframe.

Assuming that the video looks fine for others, maybe check Preferences -> Show All -> Input / Codecs -> Video Codecs -> FFMpeg and see if "Skip the loop filter for H.264 decoding" is set to "None". If not, change it and see if it as an affect upon restarting the video.

Thanks for you response. Yea it was already set to None. I know the videos are fine for other people as they have said so online in the comments. Any other ideas?

Thanks

Maybe try clicking "Reset All" in preferences. Save and Restart VLC and see if it acts any different.
