I just started using Kinovea and so far I am really impressed with it and I will immediately start to use it with my team. It has just the features I need and is really simple to use. Great job!
A suggestion. I saved all the keyframe information and closed the program. When I opened the file and pressed clicked save again I came to the "save as" dialog. When I chose the same name as before it asked if I wanted to overwrite the file. It would be really nice if I could work with a bunch of videos in a project and the program remembered what project file I had opened and saved all information to that file when I clicked save.
