We're still in the early days, but the results look extremely promising. For example, a recent Nielsen study (funded by Apple) showed that viewers of a Campbell's iAd featuring new products, recipes and coupons remembered the brand "Campbell's" five times more often than TV ad respondents. Out of 53 million impressions, 1% of users that saw the ad clicked through and spent an average of nearly one minute perusing it. That number may seem small, but this is one market to keep an eye on.
If your camera exports a spherical fisheye or dual fisheye footage, some editing softwares require you to convert your footage into equirectangular format before you can edit them. Others, like Pinnacle Studio will work with these and convert them into equirectangular format for editing. If you have a device that captures your footage by stitching multiple cameras together (ex. a device that holds 6 GoPros to capture all 360 degrees), you will still be required to use stitching software to create a 360 file, video editing and stitching software are two very different things.
When you export your video from your camera, if you are using a 360 video device chances are it is already in one of the popular 360 monoscopic formats: equirectangular, spherical fisheye or dual fisheye. When you play it back on your computer's default video player (example Windows Media Player), your footage does not look right because this is not a 360 video player. Below is likely one of the views you are seeing when you open it in a standard video player:
In March 2015, YouTube launched support for publishing and viewing 360-degree videos, with playback on its website and its Android mobile apps. Parent company Google also announced that it would collaborate with camera manufacturers to make it easier for creators to upload 360-degree content recorded with their products to YouTube. However, in 2017, Google and YouTube began to promote an alternative stereoscopic video format known as VR180, which is limited to a 180-degree field of view, but is promoted as being more accessible to produce than 360-degree video, and allowing more depth to be maintained by not subjecting the video to equirectangular projection
