Pond5 just launched an amazing free resource that contains over 75,000 free media clips, including 10,000 video clips formatted in 4K or HD. There are 65,000+ photos and thousands of sound recordings, which include some great symphony recordings.
Some of the highlights of the collection includes 5,000 never-before-seen video clips, digitized directly from the National Archives.
Other video highlights include George Meliés’ 1902 film A Trip to the Moon, along with footage from the 1952 Helsinki Olympic games, the World Wars, NASA rocket launches, and the International Space Station. Speeches from historical figures like Winston Churchill and John F. Kennedy can be heard in the collection’s recordings, along with full performances from composers like Beethoven and Chopin.

(December 13, 1972) Geologist-Astronaut Harrison H. Schmitt is photographed standing next to a huge, split boulder at Station 6 on the sloping base of North Massif during the third Apollo 17 extravehicular activity (EVA-3) at the Taurus-Littrow landing site. The Rover Lunar Roving Vehicle (LRV) is in the left foreground. Schmitt is the Apollo 17 Lunar Module pilot. This picture was taken by Commander Eugene A. Cernan.
The below footage is a clip of the Space Shuttle endeavor launching toward the International Space Station. It is available in 1080p 29.97fps as a ProRes file.
These media files appear to all be thoroughly keyworded and well-described. While you can search for specific content, the Pond5 team has put together several hand-picked collections, which you can find here, as a place to start exploring what’s out there.
