Steps
If the resolution of the video display's surface does not match video format's aspect resolution, the image must be scaled and /or cropped to match the native resolution of the display. Scaling is the process of converting image data from one resolution to another resolution. This involves a mathematical adjustment of individual pixels. The quality of the image can be impacted by an image that is not properly scaled.
| RECOMMENDED VIDEO FORMAT(S) | 720p HD | 1080 HD | Converted SD-SDI source | |
|---|---|---|---|---|
| VIDEO ZONE WIDTH RANGE | 360-2560 pixels | 640-3840 pixels | 270-1920 pixels | |
| VIDEO ZONE HEIGHT RANGE | 240-1440 pixels | 360-2160 pixels | 240-1440 pixels |
Scaling Guidelines
1:1
- No filtering, perfect pass-through
Upscaling
- Tested up to 1:17
Downscaling
- BEST quality, limit planned scaling to 1.2:1.
- GOOD quality, limit planned scaling to 2:1.
- OK quality, limit planned scaling to 3:1.
The machine won't break past 3:1, but incoming data samples will include lots of aliasing and lost fine detail. This is still useful for transition effects but isn't recommended for static setups.
