If you are on a budget and want to use motion capture data, you can find a lot of free motions on the Carnegie Mellon University's website at http://mocap.cs.cmu.edu/. Another good option is to invest in the Perception Neuron solution (https://neuronmocap.com/)—it is a project successfully founded on Kickstarter. Perception Neuron seems affordable for most indie studios or even individuals. It is a suit with a set of sensors (gyroscopes, magnetometers, and accelerometers) that the actor puts on. It works similar to standard motion capture solutions based on markers. I must say the quality of the recorded motions is mostly very good (it has some problems with rapid motions though). You also have to watch out for large metal objects, speakers, and other sources of magnetic fields in the room. But if you can't afford a motion capture studio session and want to use mocap for your project, it can be a good bet.
