For DOOH (Digital Out-of-Home) video ads in a portrait orientation, common specifications include a 9:16 aspect ratio (or 1080x1920 resolution) and a maximum file size of 15MB. Video files should be in .mp4 or .mov format, with a maximum of 2.0 Mbit/s bitrate and a frame rate of 25/30 fps. Audio is generally not allowed for video-enabled DOOH executions.
Aspect Ratio & Resolution:
9:16 or 1080x1920:
This is the standard portrait format for DOOH video. Essentially, it's the "inverted" version of the landscape 16:9 aspect ratio, with the width and height swapped.
File Format:
.mp4 or .mov: These are commonly supported video file formats for DOOH.
Other Supported Formats: Some platforms may also support .avi, .wmv, .mpeg, and other formats.
Technical Specs:
Frame Rate: 25 or 30 frames per second (fps) is standard.
Bitrate: A maximum of 2.0 Mbit/s (2Mbps) is often specified, but some platforms may allow for higher bitrates.
File Size: A maximum file size of 15MB is common for video creatives.
Other Considerations:
Black Bars/Letterboxing: Avoid using black bars or letterboxing as it can negatively impact how your ad appears on different screen sizes.
Creative Best Practices:
Keep your message clear and concise, use high-contrast visuals, and consider the viewing distance when selecting font sizes.
Example:
- A common DOOH ad size in a portrait orientation is 1080 x 1920 pixels.
- A video of 15 or 30 seconds in length is often optimal for DOOH campaigns.
- An .mp4 file with a bitrate of 2.0 Mbit/s or lower, and a frame rate of 25/30fps would be a good starting point.
