VR has attracted people from all areas of content production, from radio pros to programmers. That means that some things any camera buff would know may not be common knowledge in our industry.

Understanding global shutterA camera shutter that opens and closes all-at-once, exposing the entire sensor simultaneously (as opposed to a rolling s... More is one of those things.

A global shutterA camera shutter that opens and closes all-at-once, exposing the entire sensor simultaneously (as opposed to a rolling s... More uses all its pixels to capture the entire image at the same time, resulting in no motion artifacts, whereas a rolling shutter scans pixels from top to bottom.

The difference in results can be dramatic:

But only a handful of 360/VR cameras have global shutterA camera shutter that opens and closes all-at-once, exposing the entire sensor simultaneously (as opposed to a rolling s... More, including the Nokia OZO, Jaunt One and Sphericam. When it comes to 2D cameras that can be put into a 360 rig, there are a few more options, including BlackMagic Studio 4K, Alexa Mini, indie Dice, Codex action Cam RED Cameras with Motion Mounts.

Many of the most popular all-in-one 360 cameras don’t feature global shutterA camera shutter that opens and closes all-at-once, exposing the entire sensor simultaneously (as opposed to a rolling s...

But, if you’re shooting VR content that has a lot of fast-moving motion, buying or renting a solution with global shutterA camera shutter that opens and closes all-at-once, exposing the entire sensor simultaneously (as opposed to a rolling s... More may be worth it.

If that isn’t an option, you can reduce motion blur and image skew by filming in higher frame rates and aligning all of your sensors in the same facing direction.

Making sure that each rolling shutter is moving in the same direction is even more important when shooting stereoscopicVideo shot with two parallel cameras (or in the case of 360° video, multiple pairs of parallel cameras) Commonly referr...

If each rolling shutter is moving in a different direction, the Jelly Effect will be even more obvious and awkward in stereoscopicVideo shot with two parallel cameras (or in the case of 360° video, multiple pairs of parallel cameras) Commonly referr...
