Image resolution with illustrator files.

Hi there,
I’ve created an animation in Illustrator, but after importing the files into istopmotion, the image has become quite degraded. The resolution is awful, and there are artefacts as well.
The jpegs created by illustrator are high quality and 72 dpi.
I’ve tried creating the movie in istopmotion as an HD, for example, but to no avail.
I’m a bit confused as to what is going on.
Any ideas?
Thanks.

Please, can you send a sample jpeg image to support(at)boinx.com regarding this forum thread so we can test it?
