Magix Movie Edit Pro Plus 2018 has realtime 360 video stitching, among other features for 360 video editing.
One of the more tedious tasks for 360 videos is stitching. Almost all 360 cameras have videos that are unstitched, i.e., they consist of circular fisheye videos, most commonly two circular fisheyes in one file, which cannot be viewed on a 360 player. To be viewable on Facebook, YouTube, and others, the video must first be stitched into the standard equirectangular format:
Depending on the 360 camera and the resolution and length of your video, stitching can usually take a few minutes to several hours. Magix Movie Edit Pro Plus 2018, however, can stitch 360 videos in realtime. This is a feature that was introduced in Magix Video Pro X, Magix’s video editor for professionals. Now, the feature has also been added to Magix Movie Edit Pro Plus 2018 as well! Interestingly enough, the Magix website doesn’t mention this feature yet.
The stitching works on any side-by-side double fisheye file, which is the most common unstitched format for consumer 360 cameras. There are also presets for Samsung Gear 360, LG 360 Cam, and Ricoh Theta. You can change the angle (the field of view of each lens), rotation, aspect ratio, or alignment.
The stitching is instantaneous, which is remarkable. However, one issue is that there is a slight darkening along the stitch line, similar to vignetting. Hopefully Magix can fix this issue.
Besides realtime 360 video stitching, Magix has other 360 video editing features such as picture-in-picture, and converting 360 video into a conventional 16:9 non-360 video. Check out this tutorial for animating text within a 360 video (this tutorial was on 2017 but the steps are similar for 2018):
