IEEE ACCESS 论文提交时有这么一段话，如下。想请问这句话是什么意思？要提交一个图形摘要吗？和视频有什么关系？这部分是必须吗？
从一开始也没有提交视频。谢谢。

////////////////////////////
A Graphical Abstract (GA) which provides a concise, visual summary of the findings of your article. The GA should be a figure, image, or multimedia video from the accepted article. If you submitted a video with your article submission, this will automatically become the GA, and a still image will  be required to act as an overlay.  As a reminder, you must submit the video again with your final files or it will not be published with your article.  For more information on the GA, please go to: https://ieeeaccess.ieee.org/subm ... #GraphicalAbstracts
