Some videos will need higher bitrate to look as good as others that need a lower bit rate. Outdoor scenes usually require a lot more bit rate.

When you encode you can use a fixed bit rate or you can use CQ (constant quality) setting to make all videos have the same quality. Fixed rate all videos will be roughly same size per minute of video, CQ they will all be different sizes.

Download a x264 encoder and test some different settings on some videos and see how they look. I use ripbot264 but there are a lot of other ones.
