I currently trying to reduce my video file size for a lot of videos. They are mostly about 25 to 30 minutes and take up to 4GB which is way too much.... Can anybody give me some tips how I can reduce the video file size? I don't want to buy more storage inorder to film more...

There is a very simple formula:
Video Size = runlength * bitrate. So it follows that to reduce the size you reduce the bitrate.
In practice it may not be so simple. Firstly you have to consider the frame size >> the larger that is the more bitrate you may need to give good quality. Also a lot of movement will also demand more bitrate else the movement will not be smooth.
So you will need to experiment to see how low a bitrate you can go before it affects the viewing experience.
You can also consider reducing the frame size which then allows you to reduce the bitrate even more.
Thank you so much! I will try those steps. Hopefully it will work out well...
