The question received a number of answers, but most seemed to be answering a different question. For 20 years, I was a professional composer. I still live mostly on the royalties from that work, 12 years after I stopped writing music. Like freelance composing, there are many avenues for a freelance videographers to pursue to get revenue for their work. You might just like the idea of shooting video and getting paid for it. I still remember when, after a few years of trying to secure a record deal as a band, we got our first royalty cheques from our production music tracks. It was a great feeling to finally get some financial reward for all the hard work we had put in to becoming decent music producers. We ended up writing over pieces of music for our publisher. Apart from that, I have a number of friends and family who make a living shooting corporate videos or adverts. Aside from that, the digital world has opened up new opportunities to create revenue from from freelance videography.
