The importance of video in marketing cannot be under-estimated. The video can give more focused communication to the viewers. Content marketing is no direct interaction between the marketers and the purchasers of products/services. Here video plays a more important role by enabling the purchaser to feel the product by ‘showing’. Clubbing video with VR is most important of the latest technologies in this direction. Here is the complete guide for Video Encoding
There are many codes available for VR video. Many platforms are supporting VR format, but the difficulty to marketer comes as each of the platforms supports varying frame rates, codecs, bitrates, resolutions etc. VR video also makes the task almost impossible for the creator to create a VR video that suits all the platforms.
Before going into the encoding of VR video, one most important point to note that Chris Milk from VRSE is one of the biggest VR filmmakers of the moment.

Their videos in MediaInfo app offer the following features:
• 3840×2160 @30 (20-30 Mbps bitrate)
• H.246 baseline profile, level 4.2
• Above all, the same resolution is available for Cardboard and Gear VR as well.
Another encoding setting is Felix & Paul Studio has been second immediately to VRSE. This comes with 3840×1536 resolution. The unique feature of this system is displaying only a certain band of pixels as video and showing the top & bottom parts of the video as still images. This results in drastic reduction in pixels allowing the production to 60 fps speed. Another major contribution towards VR video encoding is the bitrate. So in effect, 12.3 Mbps h.265 video is comparable(in quality) to a 24.6 Mbps h.264 video thereby drastically reducing the file size.
After analyzing the various pros and cons of various codes available, the ‘optimal’ encoding settings would be:
• For Gear VR, codec h.265 with a resolution of 3840×2160, 30 fps and an average bitrate of 10-2-Mbps.
• For Cardboard Android, h.264 (baseline, level 4.2), resolution fo3840x2160, 30 fps and average bitrate of20-30 Mbps.
• For Cardboard iOS, h.264 (Baseline, Level 3.1), resolution of 1920×1080, 30 fps and average bitrate 10-14 Mbps.
• For Oculus Rift, h.265/h.264 with a resolution of 4096×4096, 60 fps and an average bitrate of 40-60 Mbps.
Before concluding, following encoding tools might also be useful for a look:
• MPEG Streamclip
• The compressor in combination with Final Cut Po.
Using the above codes/tools, the marketers will be able to make the best presentation of virtual reality video.
With the rapid development of the new technology, different new formats for video and audio come into being across the web. Manufacturers are researching on advanced technology and its developments for the virtual future today.
In less than a year after announcing the 360-degree format, many new developments and new cameras are launched in the market which boosts the usage of 360-degree virtual reality videos in the market.
Virtual reality video formats
Virtual reality is all about the three-dimensional video view which provides the user with a live experience. The new formats already become one of the most useful content list on the web. The formats for devices differentiate from one another.
If you are playing the VR video across Google cardboard with iPhone 6 or something means you must need 3D MP4, 3D MOV, 3D M4V will support. When comes to Android users, you can play this with 3D 3GP, 3D MP4 and 3D MOV formats etc.
The file size of the VR video shouldn’t be larger than the non-VR video format and the downloading of VR video will not burden on your computer.
Most of the VR headsets recommend 1289 by 720 high definition resolutions in order to encode the videos. The 3D movies must be encoded with one to one ratio pixel.
360 Degree video formats
The general 360-degree video formats are mp4 encoding with mpeg4 as a standard resolution ad H.264 with a high definition format is supported with the 360-degree video content.
Some panoramic video formats like MOV. F4v etc are also supported by the 360-degree video formats. The production of the 360-degree virtual reality videos has become great buzz across the web with the release of new cameras.
The playback options for the content are large and it is extremely limited and the output models support with the 360 Heros gear.
The difference is the 4k and 2k resolution is drastic that mounted VR displays like Gear VR where the pixel count is noticeable.
Virtual reality video codec’s
There are much-augmented reality experiences which include the video s main and the videos forms in different formats with a combination of the stereoscopic 3D and 360 video views. There will be many challenges in the video compressions and need for better video codec that can capitalize the potential of increasing the interframe correlation to the various types of videos.
Following are some video codec’s that helps in achieving the higher compression for Virtual reality content.
Foveated codec tracking of the viewer’s gaze to dedicated high bitrates to pixels which are inside of fovea range. This feature needs eye tracking and displays size knowledge about the distance between the viewer and the display.
NGCodec is the most well known and powerful codec for the next generation video compression since 2012. It has great acceleration and efficiency in comparing to the traditional CPU/GPU and can with standing with the higher quality compression for live encoding. The running costs are also lower and flexible.
All these above information helps you to go to the present 360 degrees and VR formats and 4K VR streaming.
