You have to work on your skills and find in which ways you can sell it to make money. In this era of e-commerce, we can almost sell anything and any service online. You can give online tuition, sell video classes, and may even write ebooks about your skill.
Have you tried using video editing software to improve video quality, remove unwanted effects from it? I know that there are many different programs for this. For example, you can find in this post a description of the one that will be convenient for you to work with. It seems to me that changing the video using such free software will be much easier than the option you proposed.
Maybe if you like teaching, you can take tuitions for young children to give them a better grasp at an early age. Or also create video tutorials for the same and post on YouTube
Puzzles are the obvious one - look how sudoku took off once it hit our shores. Do a bit of googling to see what's out there and you can either buy puzzle books and complete number puzzles or perhaps devise your own?
Look for a class to learn more about it. A computer-design class, data analysis, statistics — they can help you learn where your passions reside. While you might need to try a few things before you find your perfect match. You couldd volunteer to do statistics for a local sporting team and analyse the data, create formulas for stats etc.
