Hi Mark
Thank you for answering this post…
You have spent some time responding here which I fully appreciate…I managed to create the moving image projection using final cut and reducing the image with a black mask…
I think my post may not have been clear…the image only needed to be in focus in one location so the detailed explanation you provided was not necessary in this case…
The idea worked in principle for us, but we did loose some resolution to the image…this is something I will practice if I use this technique again…
Many thanks again for supporting my endeavors…
Cheers,
tony
