I would like to make math videos in the manner of this YouTube video. The specific features which I like in this video are:
- the interactive freestyle drawing (see the beginning of the video)
- the way different colours are selected smoothly (00:28 into the video)
- the way pre-written text can appear (01:27)
- the way existing drawings can be replaced by written text smoothly (05:37)
- the support for maths equations
I have tried Microsoft OneNote and Microsoft Powerpoint, which have been mentioned in similar questions here, but:
I understand how to make pre-written text appear in Microsoft PowerPoint, but I cannot see how to allow freehand drawing, or the interactive nature of the presentation
Conversely, Microsoft OneNote supports freehand drawing, but I am not sure about the text effects I mentioned.
