For some reason MOVs and MP4s exhibit different behavior in SharePoint Online. In the image below I have an MOV which displays correctly and runs when clicked, but the MP4 presents a folder containing the MP4, the thumbnail, and an "Other" file.

Additionally, notice the filtering option doesn't present MP4. Any thoughts here?

It may be simply encoded using an unsupported container. Can you try other mp4s that you know have H264 codec or convert this video in question?


Here is the codec information for an .mp4 video that is working in SharePoint Online for me: enter image description here


Per my test, If you switch to classic experience,upload the video and add a preview to the file, there will be a folder containing preview image and other contents. Upload videos only in modern experience will not cause such behavior.
