|Finding and buying stock video footage is very easy.|
Online footage come in many flavors. In addition to choosing the right format, such as SD, HD or greater, you need to know what kind of licensing is available. Some footage is offered as Rights Managed - where you purchase the rights based on the project and how it will be distributed. Whenever I can, I prefer buyout or Royalty-free video clips. Royalty-free means that you license the clip once and you can use the clip in any project you produce going forward.
Here are a few of the options available for stock footage online:
Artbeats is one of the stock footage companies that has been around the longest. Artbeats offers clips either as part of a collection or as individual clips. While checking out the Artbeats website for this article, I came across a cool new product that they're offering - Driving Plates. Driving Plates are for keying backgrounds into driving shots. All angles are covered in these collections including a plate for reflections.
Getty Images is one of the largest online stock footage companies. Getty Images has acquired a lot of individual collections over the years and probably has the most to choose from.
Fotolia is another large online stock footage company. Fotolia works on a credit system, you purchase credits and then use those credits to purchase clips. Fotolia also allows you to sell any footage you may have. I have a clip on Fotolia - an MGM-style film open with my dog. This is the clip from the series called Dissecting the Video: MGM-Style Film Open.
XStockvideo is a smaller collection, but they sometimes offer free clips.
Before you download a clip, make sure you have a full understanding of the licensing agreement and make sure the clip is in the proper format that you want.
