Unfortunately, different browsers handle poster images differently:
• Firefox stretches the image to fill the dimensions of the player (see Recipe 5.3 ).
• Chrome keeps the image at its original size.
• Safari displays the poster image until the video data is loaded, at which point it
displays the first frame from the video. If the poster image is a different size from
the video, the video is resized to match the aspect ratio of the poster image (see
Figure 5-3 ).

to ensure your images are sized correctly
