It is your choice to record audio before or after you have done your animation. Before works well because you know how long to animate each movement, but after works well if you have done good pre-production. Audio in Brickfilms is especially important because it not only adds to the overall story, but is one of the most effective ways to build your characters. When you decide on what minifigures to use as characters, what they are wearing is the only thing that distinguishes them from one another. Because their movement is also limited, it can be difficult to develop strong characters. This makes the dialogue that much more important.
The two easiest ways to capture audio are through a microphone or headset. With today’s technology, it is very easy to capture quality audio. If you are using a video camera, you can use the built in microphone or an external microphone. If you do not have either, a microphone or headset plugged into a computer works well. A lot of computers have built in microphones and free programs that will work well for beginning animators.
When recording audio there are a few things to remember. The first is to keep the microphone from being too close to your mouth. A microphone too close will create unnecessary popping and crackling. Secondly, take into consideration where you are recording. Try not to record in room with hardwood floors. One suggestion would be to use couch cushions or blankets to absorb some of the echo.
Along with dialogue you will need extra sound effects. Start your video from the beginning and write down the time and what sound effects you need. You can record your own sound effects, find sound effects from websites or existing programs like Soundtrack Pro. Background sound or music are also something to keep in mind.
