I would suggest using Adobe Premiere Pro and/or Adobe After Effects. Great software that I use daily and Premiere is pretty easy to learn (I believe the website has some beginner tutorials). Good music, but people don't like when you cover up exhaust sounds with music so maybe have it fade in/out at certain times. Are you vlogging? Careful about wind noise etc..
I could also use some advice on this topic. I am really new to the motovlogging thing. I am trying to learn editing, but for now I only have iMovie. I shot a bunch of video yesterday, but I didn't have a high enough ND filter, so its all blown out. Is there a way to recover this? Also, any tips on how to get more than 21 subscribers?
