Overlay Videos

The bit rate of overlay videos depends on the bit rate of the video when you uploaded it. If you uploaded a video:

  • Below 800 kbps, the video will be transcoded at 800 kbps
  • Between 800 to 1700 kbps, the video will be transcoded at the uploaded bit rate
  • Over 1700 kbps, the video will be transcoded to 1700 kbps
