Join Richard Harrington for an in-depth discussion in this video What is pixel aspect ratio?, part of Motion Graphics for Video Editors: Terms and Technology (2014).
The term "pixel aspect ratio" is often abbreviated…by the letters "P-A-R," or "PAR."…Essentially, it's talking about the shape…of the pixels; the ratio of the width to the height.…Now, these dimensions can vary by pixel to pixel,…and typically this is something you saw…in older cameras.…When many HD cameras were first invented,…storage technology was incredibly expensive.…Additionally, cameras sought to be flexible…so that you could shoot the many different flavors…of HD on one camera.…
You need to shoot standard def? They could do that.…Need to shoot HD for NTSC or PAL?…It could do that.…Rather than having to constantly buy new cameras,…many people wanted HD cameras that had…more options and flexibility.…In order to do this, the sensors would often…adjust the image when writing to disk.…For example, I've got two different video files here.…Let's open these in Photoshop for just a second.…I'll do that with a right-click…and choose Open.…
And both files come in.…Both images look very similar.…I'll just zero my views.…
