I tried to use videoscribe using Amharic fonts but video scribe doesn't support Amharic fonts.
is there any way that I can write Amharic fonts in videoscribe ?
You will need to create SVG images of the text you would like to use. This can be done easily in Inkscape (free). The article Scribing Tip – How to get Arabic words to draw well shows you how to do this (the technique will work for any language).
