Most 360 cameras with two lenses have unstitched files that are double circular fisheye format, either as separate files (as in the case of the Virb 360 raw files) or as a single video (as in the Samsung Gear 360 or Xiaomi Mijia Mi Sphere). Most cameras have stitching apps, but some do not, and sometimes there is a need to use third party stitching software.
Radu Plus posted a tutorial for stitching 360 videos for free using Kodak Pixpro’s stitching software. Here is the video tutorial by Radu Plus. Radu has used this software to stitch videos from the Xiaomi for example.
Here are the steps:
2. If you have a separate video for the front lens and the rear lens, proceed to step 3. If the video from both lenses is in one file, you need to split it into two separate files. (There are many ways to do this, such as by cropping a video or by using Adobe Premiere Pro as shown by Radu in his tutorial.)
3. You need to fix the metadata in each video file. To do that, open each file in Pixpro 360 desktop desktop software by clicking on the hard drive icon in the Pixpro 360 software. Set the mode to global and export.
4. Launch Pixpro 4K Stitcher and open the files you exported from Pixpro 360 software. Adjust the lens calibration by adjusting distance, etc. to achieve a good stitch. When you are satisfied, you can start the stitching by clicking on “Export.”
That’s it! You should have a fully stitched equirectangular video. Note: Radu will make another version of this tutorial that uses Davinci Resolve. When he has the video, I will update this post. You can bookmark this post to make sure you don’t miss it!
