I wrote an article for the latest issue of MAKE full of tips for making build videos! Check it out in print or the extended version available online:
3) Shoot while building. Always.
Get comfortable working while capturing video of your projects’ assembly. Documenting your project shouldn’t be a chore, or it won’t happen often enough. It’s better to have too much footage than too little, and the more time you spend working in front of the camera, the more relaxed and natural your movements will be. I’m so used to working with my Magic Arm clamped in front of me that it feels weird to make stuff without it.
Record key moments of your project’s construction. If there are repeated tasks, record the third or fourth repetition so you’ve had some practice before doing it for an audience. You are the cinematographer, so make your project look like it’s coming together beautifully.
5) Write a script
Describe your project as if speaking to a knowledgeable friend. Write down everything you want to include, then prioritize and edit hard. Leave only the most important bits, and save the rest for the description or blog post. Show and/or tell the viewer what the video is about within the first 15 seconds. Read through your entire script at a natural pace. Under 5 minutes? Fabulous. Under 90 seconds? Even better.
