I'm not totally sure, but I'm guessing the ipod touch records in mpeg-4.(Correct me if I'm wrong) The hd video is going to take up ridiculous amaounts of space, so can I use a video converting software to convert it and make the file size smaller? And would I just convert it to regular mpeg-4? Answers are appreciated. Edit: I surfed around the web and found that it records in h.264 quicktime mp4. I guess I can just convert this to regular mp4 to make the file smize smaller. I'm still not sure though.
