Media Uploads
Automatically associate custom thumbnail images with your videos using intelligent file naming detection.
When you upload a video with a matching thumbnail image (using the _thumbnail suffix), Ads Uploader automatically links them together. This custom thumbnail will be used as the preview image for your video ad across all Meta placements, giving you control over the first impression viewers see before playing your video.
