New episode of RGTV is up, folks…

RGTV Episode 05: Controlling Time with Audio – Pt. 1

In this tutorial, I’ll show you how to use audio to control time. You’ll learn how to make your video automatically move forward in time to the music’s beat – a technique used in tons of music videos and commercials.

Click on the image to see the example video.

I’ve noticed that the sound on MP4’s can be a few frames off when uploaded to the web – but rest assured, the motion is to the beat.

If you have never used Trapcode Sound Keys (and maybe even if you have), I’ll bet you’re surprised by what you can do with audio and time.  Anyway, I’d love to hear your thoughts on this one so please sound off.

Watch it here. And don’t forget you can get great deal on Sound Keys through Red Giant TV. Just swing by the Promo page for details.

  1. Dude, you know what separates your tutorials from most of the others? The time you take to explain “why” something is working the way it is. Good stuff. Thanks.

    Apple Motion has a built in capability that is similar to this but of course no where near as robust or customizable. + My computer usually locks up while I’m experimenting with it.

  2. Nice Idea and great explanation. Only Problem I have is the video crashing always at 15:40!

    I hope you will get this problems with the videos fixed soon, its sometimes really annoying to get interrupted.

  3. illd: “the video crashing always at 15:40!”

    I checked and the file itself is fine. Try dumping your cache, shutting down your browser and retrying the page. I have a feeling the file got corrupted during download.

    Since I use Firefox, I’d do it like this:

    Tools > Clear Private Data… > Clear Private Data now.

    You can uncheck your history and maybe cookies (although I’d clear everything that was checked by default), but make sure that cache is checked.

  4. Hi Aharon,

    thanks for the tip on flushing the cache in Firefox. Just wanted to let you know that I still have problems with the watchin the video in Firefox 3.0.5. Anyway, its running nice in Opera 9.63 – so it seems to be a problem on my system with FF.

  5. Hi Aharon,

    Thanks for another excellent tutorial. Every time I come back to this site I am reminded why investing in RG products was a wise move. Can you tell me if you plan on doing anything with 3D Stroke? I have been hoping for years, ever since I got Stroke, to see some advanced training on this plugin. I would be particularly interested in how the 3D Stroke effects were created for this video:

    Thanks again. Keep up the good work.

  6. Love it! (thanks for audio tutorials!)
