I am always impressed with the video's our members post which has prompted me to ask these questions:
1) What camera do you use?
2) What sound system do you use, e.g. personal mike, open mike, etc?
3) What editing program do you use?
When in college it was a requirement to take two semesters of film to get your journalism sheep's skin. Back then I used a Bolex 16mm camera and a separate reel to reel tape recorder. In the edit room, you cut and literally glued film together. Then sync'd sound to film. It was quite a process augmented with lots of cigarettes and coffee.
Thanks!
