I am making a devlog but editting takes time so the video will be uploaded later on, what is the procedure for putting devlogs in the jam?

You have till the end of Wednesday May 8th to complete your devlog.
You can edit the link field later or use itch.io devlog system. See https://itch.io/jam/goedware-game-jam-11/topic/3448744/how-to-add-a-developer-lo... how to add using itch for example.
