I am in Windows 7 x64, using Chrome 22. When I view an MP4 video in the video tag, it appears blurry and low-contrast compared to the source video viewed locally in Media Player Classic.

A screen-measuring app shows that both players are displaying the video at exactly its native dimensions (400x300).

This appears to be a problem only with my installation of Chrome. The video looks perfect on other machines, Macs and PCs alike. I have tried reinstalling Chrome, disabling all extensions, uninstalling my codec pack (CCCP), and reinstalling my codec pack, all to no avail.

<video src="http://d.pr/f/Nq6a+" width="400" height="300" controls ></video>​

It's actually a video size issue. A little tricky but... try this: http://webz.ro/blurry-html5-video/

  • This appears to have worked. It addresses both the blurriness and the bizarre grey tint in some instances of Chrome. – dbplunkett May 14 '15 at 15:07

I do not see any difference, but try removing the width/height attributes.

  • I tried, it didn't seem to change a pixel. Do you mean that you don't see a difference in the screenshots, or did you download and compare the video yourself? If the latter, what's your browser/OS? – dbplunkett Oct 22 '12 at 18:35
  • I just tried it. Viewed the video in VLC under Windows 7, viewed the jsfiddle in Chrome v22, both looked the same. – PhonicUK Oct 22 '12 at 18:56
  • I think it is an issue within your browser, not a generally – tobspr Oct 22 '12 at 19:14
  • I think you're right! I got to a couple other machines and it looks fine on them. Same version of Chrome. I've edited my question. – dbplunkett Oct 22 '12 at 20:31
  • Perhaps you should try updating the video card drivers on your Windows 7 machine? – TimHayes Oct 24 '12 at 21:17

Thanks for the suggestions - I tried everything and then some with no luck. However, since this has helped me discover that it's some kind of codec/software problem related uniquely to my setup, and not a "programming" problem, that makes it a whole new issue, so I'm going to mark this one as answered.
