I need help. I am trying to render and export my audio visualizer video but when I do export it the playback of that export is choppy and not in sync with my video.its like the buffering was mixed down into my video, how can this be fixed. Again please help. I used amacbook running El Capitan andAE as a free trial.
You probably rendered using the Render Cue and used the default Lossless setting. Lossless video is not designed for playback. It's for the production pipeline. You need to study up on rendering. Start here: Basic Workflow
The third section shows you how to render your project.
