Scan Lines Effect
The ‘Scan Lines’ effect allows you to place so-called scan lines over an existing video in PIXERA, which run from bottom left to top right.
These scan lines make it easy to determine whether tearing (asynchrony) is occurring.
The effect can be found in the “Resources Tab” in the “Effects” folder:
The advantage of this effect over on-screen statistics is that it can be applied to any content and can therefore be scaled up across the screens as required.
On-screen statistics, on the other hand, are only displayed per output. Only if the outputs are combined via a mosaic can the on-screen statistics be seen across all outputs.
Please see this article for more information about On-Screen Statistic
IMPORTANT NOTE
The “Scan Line” effect can currently only be applied to clips and not to color resources.
If the effect gets applied to a color resource created within PIXERA, the output and preview show a solid white.
Effect Parameter
The effect parameter allow to change how the lines look like and behave.
| Mix [%] | This parameter changes the “transparency” of the shader - for full visibility it needs to be at 100 |
| Speed | Changes the speed of the lines - how fast they run between the corners. Default is 20 |
| Line Size | Allows to change the size/with/thickness of the lines. Default is 10 |
| Line Color | Those parameter allow to change the color of the lines. Default is 1 on each. |
