The first program I am going to talk about is Movie Maker. This program is available on most windows computers (including the makerspace) and is pretty easy to use.
Movie Maker has difficulty with larger file sizes! Movie Maker is NOT the recommended video editor for higher resolution videos. Use Movie Maker for smaller files, for larger files use Da Vinci Resolve or Adobe Premier Pro.
This next step isn't required but depending on your project you might find that you need to do some colour correction. Every video camera is different and records colour differently. Also, unless you manually set a camera's exposure (which is available in DSLR) the auto focus feature will set an exposure for you which will react to different colours. Having lots of a bright colour on say a wall, could cause your camera to set the exposure to make your wall look great but, not necessarily you. Camera's also tend not to record dark colours (such as blacks) very well and also tend to record darker and/or washed out compared to what the human eye sees.
Depending on your video this might not be an issue but if you are curious as to how to correct this than watch the video to the right for a basic idea.
