In OnTheAir Video and OnTheAir Node you will see in the playback preferences an option called "Smart Resize and Graphics", so what does this do exactly?
With the option enabled:
- the resize of interlaced material will be done with a much better quality. See the following video: https://www.youtube.com/watch?v=Oc8c_aurLXY
- you will be able to overlay a static logo
But also when the option is enabled, it will use much more the Graphics card and thus you will need a decent Graphics card. So if you don't need to resize interlaced video, nor overlay logo, we would recommend you to leave the option disabled.
