To avoid some issues which may occur when rendering video in case your computer has an integrated GPU (Intel/AMD CPU with iGPU) and a discrete GPU (NVIDIA), you need to assign the preferred graphics processor for the AVS4YOU applications. This guide describes how to set the NVIDIA GPU with CUDA® technology as a preferred graphics processor used for video decoding.
If your computer is a laptop (notebook), then you can run NVIDIA Control Panel and assign the preferred graphics processor for the AVS4YOU applications as described below. If your OS is Windows 10 starting with v.1803, then you can refer to this article.
Step 1: Adjust the AVS4YOU program settings
First of all, adjust the AVS4YOU program settings for necessary applications.
For AVS Video Converter, perform the following actions:
click the "Settings" button in the AVS Video Converter main program window,
switch to the "Acceleration" tab of the "Settings" window,
check the "Use NVIDIA CUDA decoder, if possible" option,
Note: when the "Use NVIDIA CUDA decoder, if possible" option is enabled, it has priority over the Intel settings regardless of the settings specified for Intel Media decoder, so you don’t need to disable the Intel Media decoder.
click OK to save the settings,
close the application for these changes to take effect.
Note: to adjust these settings for AVS Video Editor and AVS Video Remaker, click the "Edit" option in the Top Menu, select the "Settings..." menu item, then open the "Acceleration" tab.
Step 2: Adjust settings in NVIDIA Control Panel
Run "NVIDIA Control Panel" in one of the following ways:
in Windows Control Panel: e.g., on Windows 7, click the "NVIDIA Control Panel" icon from the Classic View of the Windows Control Panel, or click "Additional Options" and then click "NVIDIA Control Panel" from the Control Panel Home View of the Windows Control Panel.
in Desktop Right Click Menu: right-click the desktop and choose the "NVIDIA Control Panel" option from the context menu,
by clicking "NVIDIA CUDA" picture in the AVS Settings window: for example, click the "Settings" button in the AVS Video Converter main program window, switch to the "Acceleration" tab, then click the "NVIDIA CUDA" picture.
Add the application you want to customize:
At the "Select a Task" pane on the left, open the "3D Settings" section,
select the "Manage 3D settings" menu item below,
open the "Program Settings" tab in the main task area on the right,
click the "Add" button in the control group "1. Select a program to customize:"
in the Windows Explorer window that opens, select one of the following .exe files: AVSInstallPack.exe, AVSInstallPack.exe, AVSVideoConverterHost.exe, AVSInstallPack.exe or AVSMediaPlayer.exe.
If you are using a 32-bit version of Windows, you should add the following .exe files:
If you are using a 64-bit version of Windows, you should add the following .exe files:
Note: for AVS Video Converter / AVS Video Editor, you should also add AVSVideoConverterHost.exe together with AVSInstallPack.exe or AVSInstallPack.exe.
Choose the graphics processor for the added application:
In the section "2. Select the preferred graphics processor for this program" choose the "High Performance NVIDIA processor" option from the drop-down list,
click the "Apply" button at the bottom of the window to save the settings.
If you further need to use the iGPU (Intel HD Graphics) for AVS4YOU programs again, you will need to make the above settings, but choose a different processor (Integrated graphics). You can also refet to this article.
Repeat necessary steps to add other AVS4YOU applications one by one at the "Program Settings" tab of NVIDIA Control Panel and choose the graphics processor for each of them.
