I usually start out with 'Hi, I'm Mark Rodriguez and you're watching (insert name of show here).
Sadly, I'm guilty of the 'hey guys' any time I'm filming 'on location' so to speak, mostly at cons and stuff. I don't know why, I just do, but whenever I film outside I just randomly start with 'hey guys, I'm at....'. And I really try hard NOT to do it because at cons for example, the video is split into separate segments it means that when it's all edited together it will have me saying 'hey guys every 2-3 minutes. So yeah... gonna try real hard not to do this for this year's con videos.
