Cool concept. Good idea to have the different colors fight each other. There's a few novice mistakes present in your short, but nothing that can't be fixed for the next time. Your focus gets off in several of your shots (live action and stop motion) Your camera twitches a lot during your stop motion stuff. Get a heavier tripod and weigh it down with sandbags to help keep it still. Also using a shutter remote can help keep your hands off of it. In shooting stop motion, it's a bad idea to have sunlight hitting your scene. The sun will keep moving. Use lamp light instead. Your stop motion frame rate is really chunky. If you want to maintain the illusion of movement you should be shooting for 12-15 frames per second. The comments on youtube talked about speeding it up, which in this case won't work, simply because you didn't shoot enough footage. Speeding it up will just make it go by quicker, but the movement will still be jerky. To fix it means a reshoot. Shoot three times as many frames. Just make each movement of each M&M three times smaller... so instead of moving a half inch across the table for each frame, it only moves a 16th. Check this guys stuff out. He's using basic household items in stop motion too. http://www.eatpes.com/index.html

It all depends on your camera. Use google and search for your cameras model number plus the word "accessories" or "remote" Not all cameras have this option.
