Here is a great piece of video shot with the Canon 5d Mark2. I discovered this work over at the Cinema5d.com forum. I have joined this forum to learn about this new world of motion and video.
The Canon 5d files are a bit of a problem with PC computers and software. I have burned lots of hours lately trying to be successful with handling the 5s files. My most recent solution is to use Adobe Premiere Pro CS4. There is a system to import the files directly into the time line and hit enter and Premiere Pro make a Proxy file automatically for you. Every other solution locks up or crashes my maxed out PC computer.
I am shooting video as well as stills at our weddings lately but I have nothing to share just yet. I am finding plenty of things to learn about though!!
