And of course, there's simply video material that is easy to compress, so using the same type of quantization, motion prediction and frame structure, some ...


I am not an Octave user, but the Video package appears to do these things. Good luck!


The intuitive way to go about this would be to consider every single pixel in your video (assuming that's only intensity, not e.g. color) a 1D signal over time. Then you'd get width×height number of crosscorrelation functions between pixel intensities and your audio. The different sampling rates of audio and video just mean that you'd need to reduce your ...
