Hacking the VSE: Syncing sound with textures


David Mcsween writes:

Have you ever wanted to time a video texture to play in a scene with it's sound? Perhaps you are character animating with reference footage but need to change the start time of the sound.

In this tutorial David shows us his process for synchronizing sound with "video textures" in 3D space. Using the trusty Video Sequence Editor (VSE) to slide strips of media, he employs simple drivers to control timing of textures in a scene. Playing them back in perfect time with the sound file.

As a bonus David uses the 3D render as a special video effect that cannot be created in the VSE alone.


  1. Nice but its not really sound matching to an exact moment in film time.
    I have to sync sometimes multiple video recordings, and blender cant give a large wave form pattern.
    I do recordings of two music bands with multiple camera's in my free time, and i'd love a zoom in into the audio track, so i can better sync video tracks and audio tracks in blender.

      I guess it depends on what you think an "exact moment in film time" is? Blender can do any frame rate you like but most recorded media ranges from 24fps up to 60fps, or just 60 samples per second. While audio recording applications can perform editing down to the frequency sample size or a thousandth of a sample per second. And you are right Blender is not tailored to show you an accurate waveform which is sad. My best suggestion is to make sure that you have some sort of sync pop at the start of your recording, like a clapper to slide sound and audio together.
