Notch

To play Notch blocks we assume that in 99% of the cases you will use Notch layer template. However, if you double click on it, you will see that the node that is actually rendering the Notch block is called Play Notch Block.

You will also notice that the inputs of this node correspond to the exposed Layer variables described in Notch layer template. Refer to that page for the explanation of the input pins of the node.

If you select Play Notch Block node, you'll see an Unload on layer exit checkbox in the Node properties on the right. If enabled, this option ensures that the Notch block is cleared from VRAM, which can be beneficial if VRAM usage is high.

Performance

We regularly test the Notchmarks of our servers. Some of these results are published on the official Notchmarks page.

Good to know: by far the most important components in the system for good Notch performance is the GPU.

Notch license

To play Notch blocks in LightAct you need a valid Notch license. Usually it's a Playback license, but Builder license also allows you to play a limited resolution of Notch blocks.For more information please contact Notch (10bit FX) directly.

If Play Notch Block node has an Error and the warning says Failed to load node contents, it most likely means that you don't have an appropriate license.

Learning edition

We don't test Notch playback with Learning edition (PLE) of Notch license, however what our users have reported is that it is possible to play watermarked Notch blocks in LightAct with PLE license, if that Notch block has been exported with PLE edition as well.

Other considerations

Integrated GPU: Please note that you need to have a discreet GPU, preferably Nvidia for Notch playback to work.

Multi-gpu systems: Please contact us before attempting to play Notch blocks on multi-GPU systems.
