To some it is a difference of semantics: when you shoot video on a DSLR the image is a composite of the image from the camera and the video, so that “lots” of images get summed together. At the same time, many cameras still have the ability to automatically split the video up into smaller pixels and stitch them together in post production. (To learn more read: What Is a DSLR?

This article will demonstrate the process of stitching together digital images, with an example of the video being put into Post Production. (To learn more read: What Is Post Production Process? Understanding Post Production Process)
Let us begin with an example. Let us assume that we have an image of a scene, a photo of the scene taken in some location, the scene being taken of a group of people or animals. Let us make the assumption that the object of the image was filmed from multiple angles.
The image is a bit longer than the size of the camera’s sensor, so it gets scaled down to 720p, or 1920 x 1080p to make up a 1080p.
With the camera set to “normal mode”, we can start stitching the image together. When you start stitching, the camera automatically captures a 2/3rds video as you stitch, for a total of 720 frames.
To stitch together any number of pixels, simply multiply the number of pixels in the image by the amount of detail you are hoping to capture within those numbers. For example, to stitch a photo at 24fps we will multiply the number of pixels captured in the image by 5 / 9 = 25 times and we will end at the same pixel as the number of pixels we were trying to capture.
This is an example of a full sized image (480×320) of something that is a bit bigger than 720p
A video camera might capture a 360×360 frame every second, but when shooting video with the camera set to capture full frame video, it can capture 1, 3, 8, or even 24 different pictures simultaneously. In other words, a camera might only have one shot of the scene per second, or multiple pictures on a shutter-release.
To determine the number of pictures that a camera needs for a 24fps video at 720p, we take the image size (from the settings menu with the camera turned on) at each frame, and multiply by the number of images that
