Editing or clipping YouTube Videos

I found that the following sites may be of good help for an instructor trying to clip or use part of a youTube video. The first three provide similar functionality: clipping and providing embed code for a clip in an existing youtube video. They are:
1) TubeChop:  http://www.tubechop.com/
2)Splicd: http://www.splicd.com/
The last one offers more options for editing and interacting with videos. It is called "embed.plus" http://www.embedplus.com and it promises more functions than the other three....

I tested them with this "Milonga"
ORIGINAL POST IN YOUTUBE:

1) One minute edit with Tubechop
