If you are like me there are times when YouTube just won't work. Not because it's blocked but because I only need a few moments of a video and the navigation tools in YouTube are limited. Here are some strategies I have learned that are helpful.
First of all when a user clicks Share under a YouTube video they can now designate a start time. This allows you to jump over some parts you may not want. To show. You can always keep the link handy by copying it and posting it to your my.uen page.
If you have your own Channel with videos that you own. You can also edit and modify them by going to the YouTube Editor
This editor lets you mash together two or more of your videos and add audio for a quick and simple mashup. You can also add pop ups and links to videos.
The final tool I was recently introduced to is Mozilla's Popcorn Maker. This Tool allows you to choose videos from a variety of sources like YouTube, Vimeo and others and then add soundtracks and popups. This is the same group that brought us FireFox so it works best in FireFox.
