Scale factor set to 1, a special case

This special case is used to temporarily change the codec parameters of your video while maintaining the original resolution - for example maybe your videos use long-GOP or the video codec is too hard to handle due to a strong compression. It does not matter if Rescaled to project size is checked or unchecked. For old computers, or underpowered computers, this option is not recommended.
