HOW TO ANNOTATE A VIDEO?

Several tools exist to annotate a video. Playposit and Edpuzzle, which are similar is many ways, are very useful to do so.

You have to upload a video on the site, which is already exist (on Youtube for example) or you can create one by yourself (note that you have to upload it on Youtube before).

First, you need to create an account (the procedure is quicker with a gmail account).

Second, you upload a video by copy/paste the URL.

Then you can annotate the video, with the different tools at disposal such as an audio recording of your voice, a document or a quizz. 

These tools are both similar, so you can choose which one is the best for you to use.
