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.

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)
