I have added a trend arrow image in my video. First of all for morphing it wont convert into a line drawing. Secondly the copied image morphs from the second along with the black erasing effect (the one that is shown in the attached image)
Looks like you have imported a Jpeg or Png and are morphing it?
Morphing works by taking the line paths from one image to another.
If the original image does not have paths and has been converted in VideoScribe, you will
get an effect like this.
This is also the case for images with transparent line paths e.g. to reveal colour fills of an image.
