The first is to record the video. This guide is written thinking in the cheapest solution. Of course, we can use a professional video camera. But almost everyone have a smartphone and it is sufficient. If we want to make more professional looking videos with a smartphone, we can use a tripod for mobiles like this or a steadicam like this.  

If the video is made with static images drawn by students, the only things we need is a scanner or make photos with the phone with a optimal lighting. We recommend using software to select, fix the light and colors, retail and organise the photographies. You can use software like gThumb.

Once the video or images and sound are recorded, we can edit them with a video editor. In the practical activities we are going to use Kdenlive because is very popular, free, open source and multiplatform. Kdenlive is a part of the KDE project, one of the most important in the free software ecosystem. Kdenlive is a linear video editor, is very powerful, but easier to use than other free alternatives like Cinelerra. With this editor you can assemble the video, add the mp3 music and apply effects or credit titles, for example.
