After uploading mp4 files, the generated thumbnails are black.


The thumbnail for a video typically corresponds to its initial frame. In cases where this first frame is predominantly black, it can result in the thumbnail representing an all-black rendition of the video.

A feature enhancement request has been initiated within AEM-CS to enhance the default video thumbnail selection process.

The objective is to avoid selecting black frames as thumbnails and instead opt for more suitable frames that better represent the video content.
