Completely agree on not setting a deadline, it will likely lead to disappointment as we tend to set unrealistic deadlines anyway, even more so for personal projects which rely on having time off of work and other responsibilities. I would even skip the "define a goal and a scope" part. Just go for it and see where it will take you, it might go into a totally different direction, which is fine.
I started recording songs for a Christmas album in 2007 and just published them this month. I thought I would never release them. And every time Christmas was over, I didn't feel like working on them anymore. So I only had about a month per year to occasionally work on them. There were years when I didn't touch them.
So after 16 years, I could see the home stretch and I decided to make it to the finish line. (I recorded the final music video today, actually.) If you had pushed me to name a deadline back in 2007, I would've said 2008.
I have a whole bunch of "projects" lying around, some of them are just ideas at this point. They will get finished eventually. Or not. No pressure.
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.
