What are video pre-roll ads?

Video posters refer to the preview images (i.e., video cover images) displayed before video playback. You can set them in [Content] - [Videos] - [Create New Video] - [Video Poster]. To ensure display quality, the uploaded files must be JPG or PNG files smaller than 5MB, and the file size should be set to 750*422px or in a 16:9 aspect ratio.

Meanwhile, it is recommended that you do not select transparent images as preview images, as this may cause abnormal display on your section pages. If you do not upload a video poster, the first frame of the video will be used by default.
