The Four Types Of Video Content
Understanding Creative Commons Licensing & Fair Use
Where to Find Free Media
Here are some sites I recommend for images, music, sound effects and b-roll footage. Just be aware of the attribution requirements.
Film Music is a website by Kevin Macleod who offers his excellent range of music both at a price and for free, if appropriately attributed.
Free sound effects - freesounds.org
Pexels provides very nice images and video footage or you can try the Freelance Video Collective.
Possibly my favorite YouTube channel of all time is Biographics. Simon Whistler combines his excellent presentation skills with background music, and transitions to images and video footage. One of the reasons I like Simon's videos is that, like me, he uses a teleprompter, which goes to show you can use a teleprompter and still look natural on screen.
I actually followed this YouTuber's advice when decorating my own house. I like this example because the videos are not polished, but notice how he records to camera, then he'll play b-roll of himself working using music to keep it engaging. A great example when just starting out.
Not On Camera:
This is one of my favorite examples of successfully monetizing a YouTube channel where the owner does not put their face on screen. They simply re-use advertising footage of the vendor's products and provide narration. I noted the author addresses fair-use in their video description.
Here is an example of a successful YouTuber who creates documentaries on war history. They simply narrate over images and video footage. I'm not sure where they source their media; however, note the frequency of transitions and movement over images to keep the video engaging.
This is an amazing example of a successful YouTuber who neither speaks nor puts their face on camera. I think these videos would be far more appealing with a voice-over or narration, but it just goes to show you anyone can be successful on YouTube.
