i made a little video tutorial about editing and encoding your stuff in blender. topics explained: how to import into and export and encode out of blender using h264. how to do a simple loop/fade of an unloopable video, how to mess with resolution and aspect ratio, how to cut out the first few frames.
as many questions about video encoding and editing popped up, i figured this might be helpful. blender is free but a bit quirky, so the format of a video tut might explain better than forum answeres
i tried to be as quick as possible, it still takes 13mins though.
sorry about my weird voice and the fluctuating volume, i had to hold a mic in front of my mouth.
