Pixelated video while in Ubuntu 18.04

us flag

When I play some video using VLC or default Ubuntu 18.04 video player, the video seems pixelated. Screenshots from Video and VLC.

I create a simple .HTML file that load the video using the video element and the video seems perfect: Browser.

When using ubuntu default player, the video seems to "lag", but is fine because I use VLC as default for playing videos.

PS: My graphic card is a AMD RADEON RX 570 4GB GDDR5.

Your links are all the same image and do not seem to be related to your question. Is this intentional?

@Nmath, please check the images carefully. The "Browser" images seems more "focused" then the others. Pay attention to the bird at left on all images

What kind of video files are these? Most video file types use some kind of compression. This is likely a difference in how the application decompresses the file during playback.

It's a .MP4 video file. If it is a app decompress problem for both VLC and Video, I can do nothing to fix it?

`.mp4` files are compressed. There's nothing to "fix" unless you are the content creator. Taking a screenshot of a single frame is always going to produce those effects, especially with text and computer generated graphics where there is a fine line between two different colors. Honestly, I don't understand why this is a problem: it's barely noticable. FYI: the "browser" one doesn't look any better - it's still fuzzy, and you can still see the compression, just in a different way.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
