Full screen Adobe Flash video can sometimes appear choppy or slow. This article covers how to fix choppy Flash video on Mac OS X.
Flash Is the De Facto Video Standard for the Web
Like it or not, Flash is still the standard for web-based videos. Although it’s buggy and has been plagued with security issues, there’s still a tremendous amount of inertia behind the technology.
Part of Flash’s longevity is its legacy. Flash was, at one point, the only way to display video content on the web. Since so many sites already have Flash content, switching to another technology is costly. It would require re-developing a lot of websites.
Flash isn’t going anywhere soon. Companies like Netflix embraced Microsoft’s Silverlight technology and then transitioned to HTML 5. Some major sites, like YouTube, have also moved away from Flash to newer HTML standards for displaying video. That said, if you watch a video on your computer, chances are it is in Adobe Flash format. With its default settings, video will eventually become choppy, especially when viewed in full screen mode.
Why is Flash Video Choppy?
Flash video uses part of your hard drive to cache Flash applications. By default, this is a paltry 10 MB. Over time, the cache fills up and Flash apps can’t function properly, resulting in choppy playback. This cache can fill up in the course of visiting a few Flash-intensive sites.
One would think this problem could be solved by overwriting the cache. Unfortunately, Flash doesn’t do this. When the cache is full, you will experience choppy video. This seems to happen more in full screen mode than with an embedded video. Fortunately, this problem is easily solved. With a few, minor adjustments, you can enjoy smooth, full screen Flash playback.
Ensure Your Flash Plugin Is Up-To-Date
Before we look at altering Flash settings, it’s a good idea to ensure that your Flash plugin is up-to-date. Adobe fixes bugs and patches security vulnerabilities with each new release. You can upgrade your Flash plugin by visiting Adobe’s website. Simply download the update and follow the installer’s instructions.
If you are using Google Chrome, it automatically includes the latest Flash player with each update. When Chrome updates, Flash is updated along with it.
Automatic Chrome updates aren’t turned on by default. You can update Chrome by clicking on Chrome > Preference on the top menu bar. Next, click on About on the left side of the Chrome window.
Chrome will install the update automatically, but you can also set it to do automatic updates. Simply click on “Set Up Automatic Updates for All Users” and enter your administrator password. This is one of a few reasons I prefer Chrome over Safari.
How to Fix Choppy Adobe Flash Full Screen Video Playback
First, launch your web browser. Next, go to the Flash Player Global Privacy Settings panel web page. This webpage allows you to alter settings for Flash, directly within the browser. Click on the second tab on the Global Privacy Settings panel. Next, slide the Global Storage Settings slider to Unlimited. That’s it! You’ll never have to fiddle with Flash or endure choppy full screen video again. If you use multiple browsers, you’ll need to make this change on each one.
Enabling unlimited storage may have the consequence of taking up too much disk space. For many users, this is a trivial amount of space. If you have one of the newer MacBooks or a MacBook Air, you may need to be more conservative about disk space. You may want to set Global Storage Settings to a higher value, but not unlimited. You can also clear out this cache. We’ll take a look at clearing out the cache in the next section.
How to Clear Browsing Data and Settings
Over time, Flash accumulates data. If you have a large hard drive, this is a negligible amount of storage space. Some of the newer MacBooks only have 128 GB solid state drives. People who own these machines may need to occasionally free up some space. Fortunately, this is easy to do. (continue…)
