My video doesn't open in VideoTweet

Your video probably isn't in a format that's supported by QuickTime. The supported formats are QuickTime Movie (.mov), MPEG-4 (.mp4, .m4v), MPEG-1, 3GPP, 3GPP2, AVCHD, AVI (Motion JPEG only).
Note that some formats will require conversion when VideoTweet first opens them.
