What does Youtube Consider Duplicate content and will it effect my ranking/traffic?

What does youtube consider duplicated content? If I have a power point type video that I already have on youtube and I want to change the beginning and end call to action, would that be considered duplicate content? If yes then how would this effect my ranking/youtube page. Will it make a difference if I have it embedded on my blog?

Youtube currently doesn't spend resources on video content analysis - only on a basic level. There are numerous instances of popular videos being recycled and reuploaded by multiple users therefore "fragmenting" video's true view count. That as far as I know is the biggest nuisance you can bump into (much like having two URLs for the same content page). Otherwise it will be fine.

If all you're doing is adding segments before and after than you might want to use YouTube editor to do this: http://www.youtube.com/editor
