I am not familiar with the camcorder or software you are using, but, in general terms, dropped frames are causedin the ‘capturing’ process, because a camcorder transferring material at a fixed-speed, tends to outrun the capacity of a computer without the ‘fire-power’ to keep-up with the demands being placed upon it. The computer, under those circumstances, has to resort to dropping-frames to ‘keep-up-with-the-play’, which is about the only thing it can do.

Another cause of jerky and dropped frames in my experience, is using a camcorder which multiplexes audio and video into a single stream, under conditions of high wind-pressures and extreme gusts. I once went to an extremely exposed coastal position locally, to try and film the shapes of sandhills being re-shaped by a gale with gusts to more than 125km/H. To give an indication, sudden changes in pressure were sufficient to cause the camcorder’s microphone diaphragm to wrinkle with a metallic tinkle in what was being recorded. That proved to be more than the camcorder was able to cope-with, and the picture became disjointed and proceeded in ‘fits-and-starts’ when displayed. However, I am talking ‘serious’ wind there, which blew my tripod over at one stage, and only being blown up against a wire fence, stopped it from disappearing over a cliff altogether. Similarly, having crouched low against the wind’s force at one juncture, I had my work cut-out getting back to my feet again.
