This should perhaps be entitled "begin to learn to use video editing software" as I have not yet got very far. However, I have worked out how to rotate a video of birds in my garden from landscape (above) to portrait (below), thanks to this useful blog post, written by the creator of Openshot, the video editing software I'm using.

I've also worked out how to export the video into different formats ...

... and to use the audio settings which are part of the advanced options of the export menu to remove unwanted sound from it, which are the three things I most wanted to do.

I'm hoping this should be enough to enable me to finally post my missing Thing To Do no. 13 - watch this space!
