What is a stitch? / What is stitching?
Videos for 360º panoramas are typically recorded with multiple cameras in use at the same time, and arranged aiming outward to capture sections of the view. We call the process of rendering the individual camera frames together 'stitching', based on the stitches or seams between adjacent cameras. Much like sewing fabric, the seam is meant to provide a continuous transition from one camera angle to the next.
Jaunt ONE camera has twenty-four cameras that must be seamlessly joined together to best present the panoramic view around the camera.
What is the difference between a preview render and a high quality render?
A Preview render uses a simple stitching algorithm that is optimized for speed at the cost of some artifacts and quality. The resulting video is 2,304 pixels wide, and has a light bit-rate and relatively small file size. We recommend using preview renders for generating selects (aka, "rushes") and to serve as editorial proxies for rough cuts.
High-Quality (HQ) renders are generated with an advanced algorithm developed by our computational photography team. This is a best-quality stitching meant to be used for final editorial assembly or post-production work (e.g., compositing for vfx). This stitching is far more computationally expensive, but results in a more immersive experience with the highest quality.
How long do renders usually take?
We use a metric to measure how fast renders will run where 1X would be returning 60FPS in real time.
Preview renders can run as fast as 1X.
High-Quality renders can take ~30-50X to render and will require more compute nodes to do the larger amount of processing.
What are supported web browsers?
We recommend using Chrome as our supported web browser. Jaunt Cloud gets tested across a variety of web browsers, including Firefox and Safari; however we recommend using Chrome as the most stable play and download experience.
For Jaunt ONE Camera rental users, why are Preview renders free while High-Quality renders have a cost?
Jaunt allows unlimited Preview rendering of recordings. These renders use a simple rendering algorithm which is very fast and not computationally expensive. We feel that providing these preview renders for free allows our Customers the freedom to review more material faster, while also allowing more people to become interested in working in cinematic VR.
The High-Quality renders are computationally expensive. How expensive? Very. Jaunt has developed a large and fast scalable rendering solution, able to bring many computational nodes together in parallel to render visually high quality panoramic video in a relatively short period of time. In order to do this, Jaunt has to store, manage, and process large volumes of data, and use many virtual computers to provide the exceptional results. While these resources are not free, rendering with Jaunt Cloud Services is orders of magnitude of cheaper than an organization purchasing the equipment and tools, and hiring the talent necessary to properly stitch large volumes of recordings to meet deadlines. And even for those that try, they would be hard pressed to do it anywhere close to the speed and the price that Jaunt is able to stitch in Jaunt Cloud Services.
Please do try Jaunt Cloud Services and compare the results.

What output formats does Jaunt Cloud Services provide?
Jaunt Cloud provides outputs of both H.264 MP4 and Quicktime ProRes 422 MOV videos.
Preview quality renders are at a resolution of 2304x1152 per eye, and are meant to be used for dailies, selects, and editorial rough cuts.
High Quality (HQ) renders are at a resolution of 3840x1920 per eye (thus, 3840x3840 for stereoscopic), and are available as high bitrate MP4 and ProRes movies, as outlined above. All renders are provided as both monoscopic and stereoscopic versions. Jaunt Cloud does not deliver lossless videos at this time.
What is the average time for stitching?
Jaunt Cloud Services begins processing the full duration preview quality render once a recording has been uploaded to JCS. The initial preview quality render of the full recording is typically available within 1 hour (often far less). This allows the process of making selects and rough cutting to begin as soon as possible. Once the desired start and end times are marked for a given recording, a clip can be created using these in and out marks which will allow the launch of the high-quality render. The HQ render is the computationally expensive render. The time to render HQ clips is variable, and depends on factors such as the duration of the clip and volume of tasks being rendered. Typically, most renders are available within a couple of hours.
Jaunt Cloud produces 2:1 aspect ratio. Can it produce 16:9?
At this time, JCS does not provide a 16:9 version of the monoscopic equirectangular image, as this is non-standard and also scales the image, resulting in a loss of quality. JCS does offer a 16:9 stereoscopic render in a Jaunt specific format, meant to be used with the Jaunt VR app and optimized to preserve pixel quality. If you wish to rescale the video from 2:1 to an alternate size, we recommend using a tool such as FFMPEG, Handbrake, or rescaling in a video editing application.
