what about this kind of workflow to prepare a good plate for tracking?
1 - Make the original plate progressive (if it was interlaced);
2 - Apply de-noise ;
3 - Choose a the highest contrast channel (by shift channel);
4 - apply sharpen filter;
5 - create a lossless .TGA sequence to import in Sintheyes for tracking.
Of course, some options are... optional. What about your experiences?
