I need a software (free ones preferred =) ) with which I can add a grid on top of video.
This is for research, where I have to follow the growth and fate of very small Items (cells) that I have filmed. There are about 1000 of them in one film and a grid added on the film would help me to count and follow them.
I have about 400 films, so adding the grid should be as easy as possible and batch tool would be extremely nice.
At the moment I analyse the videos by QuickTime pro. They are in .avi format and are made from photos taken every hour.
Thank you for your help
