Units of Size for Images and Videos

This is probably a silly question. But, I have an experiment for which videos and images will be shown, and it is important that the images and video are the exact same size. However, the size of each type of stimuli is in different units, and I cannot figure out the units of the images in order to convert back and forth and double check everything is the same size.

What are the units of size for the image stimuli? I assume the videos are measured in pixels.

You get to choose the units. Either set them individually for each stimulus in its component dialog, or set an overall setting for the experiment in the Experiment Settings dialog.

You should probably read this first though:
