Set a poster frame in Compressor
The poster frame is a still image that represents a video or audio media file or a podcast chapter in applications such as Music and in the Finder.
Note: When viewing the output file in Apple TV Home Videos, if no poster frame is set, Apple TV Home Videos automatically uses the frame 10 seconds from the movie’s first frame as the poster frame.
