How to resolve the “Out of memory” issue?

The “out of memory” issue is due to the memory allocation errors that occur in Windows 10/11, you can refer to the links below.

To work around this issue, manually configure the size of the page file. To do this, follow these steps:


  1. Press the Windows logo key + the Pause/Break key to open System Properties.
  2. Select Advanced system settings and then select Settings in the Performance section on the Advanced tab.
  3. Select the Advanced tab, and then select Change in the Virtual memory section.
  4. Clear the Automatically manage paging file size for all drives check box.
  5. Select Custom size, and then set the “Initial size” and “Maximum size” values for the paging file. We recommend that you set the initial size to 1.5 times the amount of RAM in the system.
  6. Select OK to apply the settings, and then restart the system. If you continue to receive “out-of-memory” error messages, increase the “initial size” of the page file.

Nero Video Motion Tracker FAQ

How to get a better tracking result?

To get better tracking results, you shall choose the proper target to track. The target shall have enough features for the application to distinguish between the target and the background. If you choose a plain color to track, the application will not be able to recognize the tracking area with the background. Before starting tracking, please preview your video and check if the target’s size changes much or not. If the target’s size does not change much, turn off the “Adaptive scaling“ option to get better accuracy and performance.

Video Extensions

Q: Why do I need to install the other video extensions from Microsoft Store?

A: The Motion Tracker uses a new 64-bit architecture based on the Microsoft Media Foundation technology which means the video decoding and encoding is different from Nero Video. Microsoft Media Foundation must use video extensions to decode and encode some videos like HEVC.

File Problems

Q1: Some videos can be imported to Nero Video but cannot be used in Motion Tracker, what should I do?

A: You can export the source video to AVC with the original resolution in Nero Video first. Then import the exported AVC video to Nero Video to do motion tracking.

Q2: Some video preview is not good/black/flickering in Motion Tracker, what should I do?

A: You can export the source video to AVC with the original resolution in Nero Video first. Then import the exported AVC video to Nero Video to do motion tracking.

Q3: The preview is different between the Nero Video and Motion Tracker, what should I do?

A: You can export the tracked result in Motion Tracker to video first. Then import the exported video to Nero Video to do further editing.

Hardware Acceleration

Q: What is the function of the “HWA“ button? Why is the button disabled sometime?

A: The “HWA“ button is used to switch between hardware acceleration and software acceleration during playback. When the hardware acceleration is enabled, the button’s color turns orange. The button will be disabled when the video codec does not support hardware or software acceleration.
