Here are some current problems and limitations of Expyriment you should be aware of. Where possible, we include suggestions on how to deal with or work around the issue.
At the moment, only MPEG-1 video files can be played back.
This is a limitation of the underlying video system of Pygame. On the long run, we are planning to move to a different Python video package.
Right now Expyriment only offers static 2D visual stimuli.
While PyOpenGL can be used direclty to create dynamic 3D stimuli, we are planning to add a dedicated 3D stimulus class in the future, to facilitate the creation of 3D stimuli.
