Poor video performance in Flash Player

You can experience poor video performance using Adobe Flash Player if you have low network bandwidth or lower than recommended hardware requirements. Symptoms can include:

  • Choppy audio or video playback
  • Poor picture quality
  • Dropped frames
  • Slow display times
  • Stuttering
  • Video artifacting
  • Loss of audio
  • Out of sync video and audio

Solution

Free as much network bandwidth as possible. For example, turn off applications that are using bandwidth, such as instant messengers, and peer-to-peer sharing applications.

Make sure that your computer meets the minimum hardware configurations recommended for an optimal playback experience:

In addition, if you have display problems with Flash Player, such as poor picture quality or slow display times, try deselecting Enable Hardware Acceleration in the Display panel. Deselecting this option can eliminate hardware or driver compatibility problems with Flash Player. Flash Player then uses software to scale and display the content.

To disable hardware acceleration, do the following:

  1. Right-click (Windows) or Control-click (Mac OS) the Flash application or video during playback.

  2. From the context menu, select Settings. The Display panel is the first panel shown.
  3. Deselect the Enable Hardware Acceleration option, and then click Close.

For more information regarding Flash Player's display settings and hardware-accelerated scaling, see the Flash Player Help documentation.

Additional information

Although this TechNote is intended for end-users viewing Flash video, developers should help to optimize video playback by following best practices for encoding Flash video. The following Dev article, Encoding Flash Video, is a valuable reference for developers and content providers.
