Quanta Research Cambridge and MIT researchers collaborated to develop software that amplifies color changes and movements in video that are invisible to the naked eye. The software allows you to 'see' a person's pulse by magnifying the color of the person's skin, and to 'see' a person breathing by amplifying the subtle changes in movement.

Quanta Research Cambridge has created this web application so that you can experiment with the software on your own videos and with some of our sample videos. To try it out, simply upload a video below, or choose one of the videos from the public gallery, and hit magnify. You will be directed to a new page so that you can customize your video magnification parameters, and then see the results. For more information on the technology, please visit the MIT Project Site.

Magnification enhances small movements in the source video. It works best for periodic changes such as breathing or pulse. This technique is designed to expose very small changes when the rest of the image is very still.

The public gallery shows a number of examples of effective magnification. In addition, the Public Gallery video talking shows the poor result when a video with large motions is magnified. Note that the large motions of the shadows and people overwhelm any small color changes.

If you would like to upload and experiment with your own videos, we recommend making a short (10-20 second) clip of a subject that does not appear to be moving.

We're interested in your feedback. If you have comments or suggestions, have an interesting application in mind, or would like to join our mailing list to learn about updates and new capabilities, click here or send email to
