A friend of mine just purchased a GoPro (Hero 4 Silver)for his business (he's a ski instructor). We're trying to figure out how to compress a 3 or 4 minute video, small enough to be able to email to his clients. Right now a 2 minute is about 450 mb. Any suggestions?
Yes, create a youtube channel and upload the full version to that. It's algorithms are quite good at optimising bandwidth and quality. You can then make it private if you want and send links to your clients that way in an email.
