What is the process of video uploading?

1, the site is a video playback, looked at seven of the help of cattle documents, some Meng Circle, ask everyone process
2, function one is to upload the video, can not determine the size of the video, consider a power outage continued transmission
3, upload the video can not be sure is a certain format, consider the video has transcoding
4, upload the video has a link address, play video can have drag function
Process 1 (SELECT video)-->2 (link seven kn)-->3 (video tile)-->4 (video transcoding)--and outside the chain address?
The upload process is persisted, uploaded & pre-persisted? Should be how a process
