How to Edit and Annotate Youtube Videos

I've been thinking of how to edit and annotate Youtube videos which are not mine for years. I use them extensively in my online/offline teaching and there are these awkward moments when I have to find 1minute and exactly 22 seconds and then my mouse cursor keeps searching, while the students get impatient.

Not only that! 

I'd always wanted to annotate videos, mute them and let MY STUDENTS speak while watching them. I'd successfully mute the videos, but it wasn't possible to annotate them. I would give my students clumsy prompts when to say something, and I was often a bit late or early...and again there was always me in the picture, while I wanted them to be on their own with a video, speaking. 

Take a look at this sample exercise, which can be adapted for any language (here's my version for Serbian). Simply click on play, then next or previous and let your students speak. This is extremely useful with the longish videos and for speaking exercises.

For example, with this video, one can learn / teach the following English language phrases:

• There's / there're ...
• I'd like to see ...
• Let's go to Belgrade to see...
• Shall we visit ... 
• Are you going to Belgrade to see ... ?

LOOOOOOOOOOOVEEEEEEEE IT! Thanks EmbedPlus and @redmamy!
