 Video slow or choppy

Q: My video output is slow and/or choppy


Video in VirtualDJ requires a high performance graphics card preferably with dedicated video memory. Please see the Additional requirements for Video mixing at the bottom of the following page: Minimum system requirements.

If you have a computer with good specifications and find that video runs slow or choppy, then this problem may be because your computer has dual video cards: One for high performance and the other lower performance to conserve battery life. Your computer is probably using the lower performance card for VirtualDJ, resulting in poor video performance.


Windows

In Windows, you can normally choose which video card to run VirtualDJ with by right-clicking on its icon and then choosing from the pop-up menu. Make sure that your computer is also configured for maximum performance in Control Panel Power Options

If your Windows PC is equipped with a NVIDIA video card and the option to choose is not available, you may need to enable it via the NVIDIA control panel:

  • Click Start and then Control Panel. Select Classic View from the left side of the window.

  • Double-click NVIDIA Control Panel.

  • Click View and next Add "Run with graphics processor" Option to Context Menu. Close the NVIDIA Control Panel.

  • Right-click on VirtualDJ's icon and select Run with graphics processor. Then, click High-performance NVIDIA processor.



Mac

In Mac OS X, make sure that the higher performance video card is enabled by going to System Preferences Energy Saver and choosing Graphics: Higher Performance


Please also check your computer to ensure that it is optimized for running VirtualDJ:
