I fail to reproduce this tutorial : Raster images in a composition.
Everything is OK until 3'07'' of the video. Then, when I drag my image layer to the curve layer, it is not cropped, but appears 'above' my shape.
On the other hand, if I simply draw a shape, select it, click insert (above, on the right) and then only place a picture directly in the shape, that does it.
Surprising, isn't it ?
[ps : great software, great tutorials. Thanks again.]
