Videos must use the MP4 container and be encoded using h264.

• Ideally the file size will be 100MB or under
  • Min: 0.1MB
  • Max: 30MB
• Ad length must be between 5 seconds and 300 seconds (5 minutes)
• Visuals and sound must not be distorted
• Ad should be in 16:9 aspect ratio
  
  

Static images must be in the JPEG, GIF or PNG formats and cannot be larger than 999 x 999 pixels. Please note, these guidelines apply to all static images, including logos.

Digital video and static files must follow the above formats, although video must be shorter than 105 seconds.

Important Note: Make sure your file size is proportionate to ad length. For mobile videos, 1MB per 30s of video is recommended. Large file sizes may impact respondent experience and drop-out rates.

Early-stage stimulus can be either an image (text-only or with text and pictures) or in a video format. If the image format is used, then respondents will be able to zoom in and out when exposed to the stimulus in the survey.

• Stimulus requirements:
  • Image formats: JPG, JPEG, PNG (Max pixel resolution – 1200x1200, aspect ratio options 3:4, 4:5, 3:2, 4:3, 5:3, 5:4, 16:9)
  • Video formats: MP4 (Min file size – 10KB, Max file size - 30MB)
