-
- File size: The video file must be 500 MB or less.
- Depending on the users' phone model and operating system, longer than 4 lines of text may not show completely on the screen. Instead, the text would be covered by a See more message.
War Room Tip:
-
Keep the ad captions within 50 characters for CN/JP/KR or 100 characters in other languages to avoid being covered by See more.
-
Use vertical, full-screen video: Always use vertical videos. Horizontal videos are not allowed. Frames and bars can be allowed when they match the brand style with a clear creative concept applied or they are part of Branded Effect design. To deliver an immersive experience, content should take up the full screen.
-
Exception: Horizontal movie trailers, which occupy the whole screen and instruct the viewers to rotate their devices in advance, can be allowed if they remain vertical in the first 3 seconds of the video.
