Replying to Transferring videos from one computer to another

I have a bunch of my Gopro videos from this summer and I want to be able to move some of them from my laptop to my mac so I can edit them and stuff. The issue is how to transfer them. Originally I used a flash drive, but it takes forever and it seems like once I transfer a video with the flash drive and then take it off of the flash drive, the overall memory on the flash drive decreases and I can barely fit any of the video on it. Is there some way to fix this? Or is there just a better way to transfer all my videos to my computer?
