The boom of VR (short for Virtual Reality) is visible. It is a technology that overturns the traditional sense and surpasses 3D, offering you true sense of a sensory experience. Thus, most people want to enjoy it. So, how to watch VR video content at home from Mac OS Sierra? There are several requirements. We all can have an immersive feeling when watching virtual reality videos. But unfortunately VR video resources are limited and some VR videos can’t play. At this time, a VR video converter is urgently in demand. Learn >> 3D Movie on VR Headset Playback FAQ.
For your reference:
[1] What is VR: The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’.
[2] What is VR headset: A virtual reality headset is a heads-up display (HUD) that enables users to experience and interact with simulated environments through a first-person view (FPV). 
Why do we need the Top VR Video Converter on macOS High Sierra?
The why is very simple. You bought a 3D VR heasdet, NOT a personal computer. Supporting certain formats and bit rates may require extensive processing power (not available by your VR heasdet/phone’s video processor). With an increasing number of formats in video being distributed as downloadable content online, you’ve probably found that the video you have right now isn’t compatible with VR heasdet. That’s where virtual reality video conversion comes.
What you can do: Get a transcoder and convert all your non-VR video files to a VR SBS format supported by VR heasdet, change a VR video format/resolution to be available to VR Players, or transcode a virtual reality SBS video to 2D normal format for playback on PC/Mac, iPhone, iPad, Android, etc.
Best Video Formats for Normal VR Headsets
Usually, for some VR Headsets like Google Cardboard, the best VR video format depends on the the devices it connect. For example, if you play a 3D video on Google Cardboard with iPhone 6, you’d make sure your 3D video is 3D MP4, 3D MOV, 3D M4V. But for Android mobile phone, you can play 3D 3GP, 3D MP4, etc on Cardboard. This adapts to many VR headsets in the market, like Freely VR, Sony Morpheu, PLAY VR, etc.
As for those top popular VR headsets, such Samsung Gear VR, Oculus Rift, Google Cardboard, Zeiss VR One, etc, the best VR video formats for Gear VR is 3D MP4, 3D AVI and 3D FLV. The best VR video formats for VR One is 3D MP4 and 3D MOV. For DK, the best VR video formats will be 3DMKV, 3D MP4, 3D AVI and 3D WMV. Top-Bottom 3D is supported by VR headset while the best mode is 3D SBS.
Best VR Video Size
The file size of a VR video is not supposed to be larger than that of a non-VR video (common SD/HD/4K video). And unlike 4K UHD, downloading a VR video won’t increase the burden on your computer, USB or HDD.
For most of the VR headsets, we recommend using 1280×720 HD resolution to encode your videos. Higher resolutions will not provide any better quality, meaning you’ll waste space and processing power.
And for Gear VR, 3D movies should be encoded “full side-by-side” with a 1:1 pixel aspect ratio. Content mastered at 1920×1080 compressed side -by- side 3D should be resampled to 1920×540 resolution full side -by -side resolution.
