Transcode Video with Avidemux
You would think that find a good video encoding app would be easy. Solid command line tools like transcode, FFmpeg, and MEncoder do exist, but readily available graphical apps are hard to come by. Frustrated with the dedicated alternatives, I turned to Avidemux. It's known best as an easy to use video editor, but the controls also make it very easy to just transcode video.
After unsuccessfully fiddling around with dedicated video encoding apps I thought to try a video editor, and Avidemux was calling my name. I had heard good things about the program, but hadn't given it a try yet. After Avidemux loaded for the first time I quickly realized that it was exactly what I was looking for.
The first step, of course, is to pick the video that you want to transcode. Click the Open button from the toolbar and select the appropriate file.
