Audio control of video. Need help for a project.

Nov 13 2011 | 9:27 pm

For my digital media class I am doing audio control of video. I need my video to move forward 30 frames eachtime it receives audio input (from a contact mic). How might I do this?
Bonus points if you can also tell me how to move the video forward based on amplitude ( louder sounds = forward more frames)
and I would like the video to eventually loop but I think that’s all figured out.

It sounds to me like your smart enough to figure this out. You need a spl detector, send that data to be an input to the playing of the video. You will also need to set a threshold or then low freq and system noise will move the video as well.

Hey thanks for replying!
Hmm maybe I sound smart, but I’m really a beginner with this program. Could you give a bit more info? So far the video starts and loops when it receives audio input but I want it to move forward 30 frames then stop until it receives another message to start again.
I also figured out how to make the video jump back and forth depending on the amplitude of the audio input but what I want is for it to move forward a certain amount of frames depending on the amplitude then stop until it receives another input.

I am not by any means a master of jitter, but on a quick glance it looks like jitter tutorial 4 has the answer your looking for (scrubbing).
