I am afraid it is a little difficult to upload videos in common HTML. Generally, the video file size is relatively large, which is several hundred MB. In addition, the network speed is not stable on the Internet.
It may take a long time to upload a file of several hundred MB. if the server gives each user such a long connection time, other users will not be able to access the file.

QQ mail has a large attachment Upload function, which has the resumable Upload function. Upload of large files such as videos is best achieved through the resumable Upload function.

There are many examples of uploading images to the Internet. For example, swfupload.
