Camera rigs like the GoPro Omni or the Z Cam S1 will produce multiple mp4 files per take one for each lens, as in the image on the left. The first thing to do is look at what kind of unstitched footage your camera produces. There are others, but they tend to be more intensive and difficult to use for little increase in quality, so we’ll be talking about Autopano for the remainder of this guide. Kolor’s Autopano is the most popular comprehensive program to stitch with manually. There are two situations, then, where you’d want to stitch manually using a more sophisticated software: Your camera doesn’t come with an automatic stitching software, or you want to have more control over making a video appear cohesive by hiding particularly tricky stitch lines. In the picture below, the subject was standing directly in the overlap between two lenses, and his face got caught in a stitch line. The areas on either side of stitch lines might look a bit discolored in contrast to one another, because the cameras were automatically set to different light settings. “Stitch lines” in 360 are the areas of overlap between the lenses that have been stitched together, and appear as disconnected lines that are clearly meant to be continuous. This automation makes life remarkably easier for generating a vast amount of 360 content quickly, but comes at the cost of inexact stitching. The Gear 360, for example, comes with software called “ Gear 360 Action Director.” Importing footage from the camera into this software automatically stitches the video for you, no additional work necessary. Most 360 cameras have proprietary stitching software that stitch automatically in most cases. Garmin and other companies have recently demonstrated interest in creating cameras that stitch on board, meaning that this step will likely soon be technologically obsolete, but for now, we have to figure out a way to blend the lenses into one video on our own. These video files must be combined using “video stitching” software on a computer or phone before the video becomes one connected, viewable video. Different cameras have different methods of outputting footage, but usually each camera lens corresponds to a separate video file. You can also create original panoramas with projections like Little-Planet or Mirror Ball.For the time-being, footage filmed on most 360° cameras cannot be directly edited and uploaded for viewing immediately after capture. If you have a panorama that includes architectural monuments, you might prefer to retain the rectilinear projection, which will preserve their straight lines. A classic 360° photosphere is created by choosing the cylindrical or spherical projection. Choose the projection with a click and adjust your image with the Panorama Move option which will remap your projection on the fly, you will see a real-time preview final render. Play around with both the DPI and the scale factor as different values are best used for different use cases.Īutopano can project your panorama in many different ways: Little-Planet, Panini, Hammer, Mirror Ball, Orthographic and others. Using a dense dots per inch of 300 will enable you to print your work out. Here, you can choose to save your work in Photoshop’s native file format for ease of use their which shall keep all layers intact for fine tuning of your image. Once completed, click the cog button and an options dialog shall appear. Playing with the Gamma point level makes the image brighter or darker, whereas the black and white points of the histogram help make sure one achieves the tonal range required. Adjusting Levels in autopano is similar to that of when adjusting levels in an image editing program such as Photoshop, Affinity Photo or GIMP. Tone Mapping RH2 is actually more useful for high dynamic range (HDR). You may play with that until you are satisfied or use the Levels as described below. This dialog enables the user to adjust luminosity through the Key value. The panorama produced by autopano from your image set may have tonal aberrations and as such you may use the built in tone mapping features to correct this to start, use ‘Tone Mapping RH2’. If the image that Autopano has automatically created is not level then you may use this function to fix it.
