Drops in Frame Bitrate or Frame Loss

Q. Why is there a drop in the frame rate or intermittent frame loss?

A. You may need to adjust some settings in the first mile of the stream.

High-definition devices typically capture video at 30 or 60 frames per second (fps), but the standard for video streaming is 29.97 fps in the U.S. and Japan, 25 fps in the rest of the world. For remote cameras used to capture security footage, a frame rate of about 10–15 fps works fine.

Unhealthy Stream with Drops in Frame Rate & Intermittent Frame Loss:

Possible Causes:

  • The network is congested and frames are being forced to drop
  • The video bitrate is too high for the encoder
  • Lack of bandwidth
  • The CPU usage is too high (perhaps from too high of bandwidth)
  • The transcoder is overloaded and can’t set the proper frames per second

Troubleshooting tips:

  1. Lower the video bitrate
  2. Switch to an ethernet connection
  3. Disable all background programs running that may be consuming the CPU
  4. Select the geographic location closest to you in Wowza Video
  5. Check you are using the latest encoder version
