Two Simultaneous Videos Demo Experiment Run Experiment

Two Simultaneous Videos

Jaap Murre

This demo shows how you can show two videos simultaneously or as is the case here, the same video in two different positions.


This script also demonstrates how you can hide the controls by accessing VideoElementJS styles and how to completely disable the keyboard short-cuts to control video playing.

If you are a registered user and signed in, you can here copy this script and its stimuli to your own account, where you can edit it and change it in any way you want.

It is absolutely free to register (no credit card info asked!). You can then instantly copy this experiment with one click and edit it, change its accompanying texts, its landing page, stimuli, etc. Invite your colleagues, friends, or students to check out your experiment. There is no limit on how many people can do your experiment, even with a free account.

The catch? There is no catch! Just keep in mind that with a free account, you cannot collect data. For teaching that is usually not a problem. For research, prepaid data collection (unlimited subjects) starts as low as €10.00 for a 10-day period.
