My wife got me a GoPro for Christmas. I took a video of an ice race last weekend, Can somebody give me step by step instructions on how to make the file size smaller. I would also like to edit these things a bit. I already downloaded MPG_streamclip. I saved the MP4 files as .avi file and the thing went from 1.5GB to 6.5GB. I would like to share these videos with some friends.
