Sometimes, deadline for private projects are necessary and for some projects they could be completely irrelevant. Also, it is a matter of personal choice and character to set one.
The idea part is very interesting. Basically ideas are the raw, unstructured parts of projects. There is an exploration aspect to it and to realize them may bring a lot of joy - without calling them a project just yet.
So maybe your decision to finish all those ideas, wrap them up, put them together, create the video, is the very incarnation of the project. For that you probably set some purposes and goals and maybe even a deadline.
