I worked for a small agency that had several national clients as a staff motion designer and video editor early on in my career. Some of our clients included Discovery Channel, National Geographic, and The Smithsonian.
I worked on installation videos for museum exhibits. I worked on title sequences and bumpers for mid atlantic marketing and cable tv versioning graphics packages. We output to decks because stations still use tapes. SRCam, Beta, patch bays, it was full service. Not to mention a full on sound engineering studio next door that we were partners with.
