A high amount of movement or action in the content of streaming video can result in a blurry or jumpy picture. A video of a person giving a lecture may therefore be clearer than a video of a basketball game when they are streamed over the Internet. High Internet traffic or a slow Internet connection speed may also cause blurry video. Any of a few adjustments may eliminate blurriness and improve the overall quality of streaming video.
Shut down nonessential applications. Maximize all the windows open on your computer. One by one, close all programs and windows other than your Internet browser and media player. You will free up computer space and power to direct it entirely at the video. This may fix the blurriness.
Open your Internet security program and click on "firewall settings." Turn off the firewall. Watch the video to see if the blurriness is gone. If so, when the video is complete, turn your firewall back on. If the video remains blurry with the firewall off, your firewall setting is not the cause. Press pause and turn your firewall back on.
Open your media player and select "options" or "preferences." Set your player's settings to match your web browser's default settings by clicking "use browser proxy settings" in Windows Media, "use my web browser's HTTP proxy" in Real Player or "Automatic" streaming for Quick Time Player.
Postpone viewing the video for an hour. Blurry or jumpy streaming video, starts and stops, or out-of-focus and hard-to-view video may indicate too many people are trying to view the video at once.
