To edit 360° videos shot by either a RICOH Theta S or a Theta M15, you will first need to stitch the dual-sphere video into “equirectangular” (flat mode) video first. This (below) is the original dual-sphere video footage shot from a Theta S, before flat mode.
Go to Ricoh’s website and download the basic application for RICOH Theta.
First, launch the RICOH Theta application and drag and drop the original dual-sphere footage directly into the main interface. Then select the output “format” and “destination” of your video.
The RICOH Theta application will then begin the stitching process.
Once the stitching process is complete, you will find the stitched file in the assigned folder from step 2, which (below) looks like this.
