Important Notes

  • Ensure that your video files include audio. If your video file does not have any audio, you will not be able to upload it.
  • Upload the highest quality version of your video file. For ads hosted on Basis DSP, the DSP automatically transcodes the video into all necessary formats.
  • Upload only a single size for each video. The DSP automatically creates copies for each size used by your ads.
