All you have to do is reformat it. If your on a mac, download a free program from google called %26quot;iSquint%26quot;. If your on a PC or Linux computer just open your web browser and go to google. Just search the term %26quot;Free .avi to .mp4 converter%26quot;. There should be a ton of hits. If you want a specific one just message me.
