Mondrian Transcription Software

Welcome to Mondrian Transcription! This tool allows you to transcribe fine-grained movement data from video. To get started, use the top buttons to load a floor plan formatted as a PNG/JPG image and video formatted as a MP4 file.

Then, click once anywhere on the floor plan to start recording movement data synchronized to the video. As you move your cursor over the floor plan, positioning data is recorded. Play/pause recording by clicking on the floor plan. Press the 'f' key to fast forward and the 'r' key to rewind video and data recording in 5 second intervals. Use the top buttons to clear/save your recording data as a CSV file.
