Searching for the right video or photo? Check out Pexel.
Often videos are expensive to create and need permissions ranging from participants to places and spaces of the recording. Pexel offers a plethora of video and photo resources at no charge for your use commercially.
"Pexels offers completely free, no-strings-attached photos and videos. If you’re impressed with the high quality of the imagery available, it’s 100% thanks to the generous contributions from our talented community of photographers.
While it’s not required, we encourage you to give these contributors credit every time you use one of their photos—they always love to see how their photos and videos help people."
