NVIDIA SDKs

Introduction #

The following nodes require the installation of the Video Effects and AR SDKs from NVIDIA’s Broadcast SDKs to function correctly:

Both the Video Effects and AR SDKs can be found here.

To guarantee that you install the correct SDK versions for your machine, please make sure you read the information below.

Caveats to NVIDIA SDK installation #

It’s important to install the correct SDK version for your machine and GPU, as not all SDKs are backwards compatible. In particular, AR SDK version 0.8.7 is not compatible with earlier versions.

This has been a common issue with 50 series GPUs, which only support AR SDK 0.8.7. As a result, features like Face Tracking and Body Tracking could not be used on these machines.

We now have a solution which allows you to use the latest AR SDK (0.8.7), but also run an older version along side it. What this means is that you can run the latest AR SDK on 50 series (and other compatible cards), but then if you need to run blocks exported using an older AR SDK, Notch will just grab the older SDK and use that instead.

Older versions of the AR SDK will still be located in the same folder as they always were (C:\Program Files\NVIDIA Corporation\NVIDIA AR SDK). And old versions of Notch will still look there for the SDKs.
Newer versions of Notch will now look in the folder C:\Program Files\NVIDIA Corporation\NVIDIA AR SDK 087 for the AR SDK, so the newer SDK must be installed there.

Blocks exported using the AR SDK 0.8.7 will only compatible on machines running the AR SDK 0.8.7.

Blocks exported using pre AR SDK 0.8.7 versions will only be compatible with machines running pre 0.8.7 AR SDK versions.

How To Install The NVIDIA SDKs #

Video Effects SDK #

The Video Effects SDK is currently backwards compatible. So simply install the latest version that is compatible with your GPU from here.

AR SDK #

Going forward, Notch will be using the latest NVIDIA AR SDK (currently 0.8.7). To install:

Download the AR SDK 0.8.7 from here.
Install the AR SDK
Go to C:\Program Files\NVIDIA Corporation
Change the name of the folder “NVIDIA AR SDK” to “NVIDIA AR SDK 087”

To install both the 0.8.7 AR SDK, and an older version:

Install 0.8.7 as above
Then install the older version, leaving the folder the same name

So the 0.8.7 AR SDK will be located in C:\Program Files\NVIDIA Corporation\NVIDIA AR SDK 087

The older AR SDK will be located in C:\Program Files\NVIDIA Corporation\NVIDIA AR SDK

FAQ #

I have a 50-series and want to face track - what do you have to do

50-series cards are only compatible with AR version 0.8.7, so you need to install version 0.8.7 of the AR SDK.

I have a 40-series, but my media server is 50-series - what do you have to do

50-series cards are only compatible with AR version 0.8.7, so you need to make sure you have the AR SDK version 0.8.7 installed on your 40 series card machine. This means that when you export your block, both the block and the media server will be using the same SDK version.

I have a 50-series card, and want to run a block that was exported using an old version of the AR SDK

50-series cards are only compatible with AR version 0.8.7. So blocks exported using a different version of the AR SDK will not work.
