The easiest way to record your matches is to simply use your digital camera, video camera, or cell phone camera & simply point it at your TV to record. Then, simply upload your video to YouTube, and I can then post it here on the SFCC site from there. Fortunately, with Super Street Fighter IV, all online matches are record temporarily for you in your Replay Channel battle log (the last 20 matches, I believe). From there, you can actually permanently save your replays to your HDD within SSF4. This makes recording your matches with a digital camera easy since you can play your match and then record later. Anyone try playing while holding your camera? Not very good for your winning percentage. However, if you can place your camera on a tripod or dock while it records, that will obviously free up your hands to play. I did last season while playing my matches, and for some, the live recording of an actual match would also pick up on any reactions, good or bad. It's great to post your vids online to share, but I think everyone will agree that none of us want to be in a video that goes viral simply because of your hilarious reaction, good or bad.
Below are some of videos (past and present) submitted by members who have used a real camera:
Here are a few of the videos I've recorded with my setup:
Good luck!
