I took a video on my iPhone 4S upside down. I searched around the Internet and found a post stating that Apple's QuickTime Pro can losslessly rotate/flip videos. First of all, is this definitely the case? My problems would be irrelevant if there were other programs that would be able to flip my video's orientation while keeping 99.99% of the quality.
If QuickTime Pro is the only/best program to use for this purpose, why is the video portion of the file not showing up? When I play the video in QuickTime, I view a black rectangle taking up the entire resolution of the video and I am able to hear the video's audio. If I open the same video file in VLC or Windows Media Player, the video shows up fine along with the audio.
