Making a video used to be a daunting task indeed. You'd need an expensive camera, special software to edit, and likely some professional help. Back in the actual 70mm or 35mm film day with no SIM card or online options it was even more prohibitive.
Now you can do a Zoom session, record it, and post it on YouTube. You can create your own YouTube channel, which can even monetize your creative work even as you make videos that participate in democracy.
Yes, you can make it fancier and more appealing with all the above helpers--great editing software, professional assistance, and so forth.
Whatever you produce, consider making very short vids that people will actually watch to the finish. Do a series of three-minute videos rather than one 90-minute blockbuster that few will even start. Even better, do the long form plus break it down into discrete clips.
In some ways, it's almost like a letter to the editor; make just one primary point, and make it succinctly with explosive intellectual entertainment value. If you do a Zoom, have a Powerpoint ready so you aren't just a talking head. Rip through 15-20 slides, at least, in three minutes. Start and finish with yourself. Do the Zooms until you are happy with the product or learn to edit the Zooms. Either way, post with power, with confidence, with a fast-moving alluring message. You will find your own style, your own voice, and you will be a more effective agent of change.
I will always love the answer given many years ago to an old movie director to a question about how he made films that were so successful: "I grab the viewer by the throat in the first 30 seconds and I never let go."
Your videos may be the trigger to action that saves democracy.
