thank you I think I am starting to slightly get my head around this!

I would like to double if i am correct about this section?

 //y is set at 0 and if that value is lower than video height then add the value
  for (int y = 0; y < video.height; y++){
// this sets the boundary for the loop to take place? which means the width of the canvas (but not sure how + drawPositionX adds to that because it is set to 0
      int setPixelIndex = y*width + drawPositionX; 
//this takes the video width and adds the section of video to that?
      int getPixelIndex = y*video.width  + videoSliceX;
      pixels[setPixelIndex] = video.pixels[getPixelIndex];
    }
