Video bitrate too high

Video bitrate is the amount of data contained within each second of video and plays a big role in a file’s visual fidelity. In general, a higher bitrate equates to a clearer and sharper image regardless of a spots resolution. However, too high a bitrate may have more drawbacks than benefits. Increasing the bitrate will also increase the file size of your video often with diminishing returns the higher you go. Some broadcast systems may also fail to play video files that have too high a bitrate since their equipment can’t process the amount of information required each second.

Examples and Possible Solutions

To ensure the quality of spots sent from Spotloader we require they maintain an acceptable bitrate determined by their file type. Spots that have too high bitrates will need to be re-encoded with a lower bitrate. We have tutorials available that can help you encode your file with an acceptable bitrate.

  • Bitrate for MPEG-2
  • Bitrate for MXF
  • Bitrate for H.264

HD: 35 Mb/s
SD: 25 Mb/s

HD: 35 Mb/s
SD: 15 Mb/s

HD: 30 Mb/s
SD: 30 Mb/s (IMX30), 40 Mb/s (IMX40), 50 Mb/s (IMX50)

Example:

Video bitrate too high: 120 Mb/s.

Possible Solution:

A 120 Mb/s bitrate will require a lot of information to be processed each second and many broadcast systems may not be able to properly play the spot.

Solution: Re-encode this spot with a smaller bitrate that matches our file format specifications.
