Adding the Dialogue
Whether you’ve created the stop motion production in a special software application, more than likely the program will also provide you the capability to record and embed audio tracks as well. Other options include adding audio through a soundtrack software program, or you want to use an external source, such as a Merantz Portable Recorder. Whichever way you choose to add or capture audio, please keep in mind that the process becomes tedious and having patience will be a great virtue!

Software applications that allow you to record audio directly into multiple tracks will be your most convenient option. However, if recording audio into an external source, you’ll need to sync the audio footage with the visuals. When syncing, create temporary digital slates on your editing program. It doesn’t matter what or how you do it as long as you know the beginning of each take for both, audio and visuals. Also, the voice talent needs to know when to begin. A visual slate should be a simple cue such as a colored matte, text, a countdown, or timecode. The audio slate can be a simple clap, either made by hand or with a clapboard, at the specific point the visual is slated. Be sure to state the scene and/or shot before the clap.
Set looping points in the video ready for syncing, whether an entire scene or just a section of one, and play it over and over again. As the video loops this gives the voice talent(s) enough takes to make the sync look great.*
Watch the footage a few times and have the voice talent do ‘dry runs’ (testing) before actually recording the audio.
*If you’re recording the audio into an external source, there’s no need to do a vocal slate for every take, just be sure you include a vocal slate just before your clap before the first take. (ex. you say in the mic “Looping for scene 3." Then clap on visual cue. Every take there after, just clap as the visual slate loops back around.)
