Noah,
yes I’ve output the original video file as a numbered sequence of TIFF images from my editing program, all into the same folder. The format is alpha characters space numbers e.g. FRED_123
I’ve just followed the procedure you outlined but when I click calculate it reports just 1 in all the boxes. I’ve tried several variations to get it to ‘see’ all the frames in the file but without success. I’m using Ver.8.5 – would this make any difference?
Thanks for the response, I did think about the approach you suggest but I can’t see how to get the Material dialogue box to let me load an image sequence instead of an AVI. Do you know if this possible?
