Hello Cui,
Thank you for your question. EmotivPRo has no feature to export the data as video or graph but you do have the playback option on your recording within EmotivPRO. You may use a third-party screen capture software like Bandicam or Screencastify to record your screen while you playback your recording.
Raw data can be exported as .edf file format which is already a line graph.
If you have other questions, please let us know.
