This guide helps explain terminology related to still image files.
For steps on how to import still images with your compatible Roland switcher, search for that product in our knowledgebase, or contact Roland Support via Roland Backstage.
Introduction
The video switcher world and the photo editing world have different definitions for the term "resolution".
This guide will break down the differences between the two. It's helpful to understand this distinction when creating graphics in your image editing software that you will later export to your compatible Roland switcher.
The Video World's Definition
Roland refers to the size in pixels of an imported still image as it's resolution:
- X pixels wide by Y pixels high, like 1280x720 or 1920x1080
Here's an example of the image requirements for the V-8HD:
The Photo World's Definition
Image editing software refers to these numbers as an image's "dimensions", because resolution has a different meaning.
Image editing workflows define resolution the number of pixels per unit of distance measurement (inch, cm, etc.) in an image, when it is displayed.
Additional Terms
In this case, resolution is interchangeable with PPI (pixels per inch) and DPI (dots per inch).
Resolution here might also be confused with pixel density, which relates to displays like TV's and monitors.
Tying it All Together
So, what does this all mean? If using image editing software to create still images to later import into your compatible Roland switcher, the dimensions setting in the image software refers to the resolution in the switcher, which is:
- 1280x720 if set to 720p mode
- 1920x1080 if set to 1080i or 1080p modes
| Resolution | Dimensions | |
| Roland Switchers | The total numbers of horizontal and vertical pixels | Not Applicable |
| Image Editing Software | The number of pixels per unit of measurement | The total numbers of horizontal and vertical pixels |
