I've come across a Scriber who was able to draw images and zoom/pan the screen simultaneously. How was he able to do this?

Please provide a link to the video if you want opinions about the video.

What you described is not currently a feature of videoscribe.

At the 10 second mark, you can see the zoom and draw
At the 30 second mark, you can see the pan and draw

If this is not a feature, any idea how the user was able to do this? Do you think he used PNG sequences?

You could ask him, but it looks like he is intentionally ignoring questions about how he made the video.

My guess is that he exported a png sequence to retain transparency, then used video editing software such as adobe after effects.
