  • Linux: /Home/USER ACCOUNT/Lightworks (Linux)
  • Mac: Drag and drop the Lightworks.app to the Applications folder within the DMG overwriting the previous installation with the latest version.
To confirm the version of Lightworks you are running check the version and revision number at the bottom of the Project Browser screen after starting Lightworks.

How do I uninstall Lightworks?

Importing

I am having problems importing a particular file, what can I do?

The list of codecs that Lightworks supports can be found here: https://lwks.com/lightworks-tech-specs Just beacuse a file is in an . AVI or .MOV container does not necessarily mean it will import into Lightworks. .AVI and .MOV files are simply containers that can contain a wide variety of codecs within them. We recommend you to download and install MediaInfo from the Tools sections of the Downloads page: https://app.lwks.com/downloads Instructions for using and posting your information regarding MediInfo can be found in this Forum Post: https://forum.lwks.com/threads/how-to-post-mediainfo.235619/#235619

Exporting

There is only an option to export as YouTube/Vimeo at 720p quality. Why are all the other options not available?

The Free version of Lightworks has restricted file output limited to YouTube/Vimeo .MP4@720p. In order to access the full exporter profiles you will need to upgrade to Lightworks Pro. Please visit this page: https://lwks.com/lightworks-tech-specs/ to compare Lightworks Free with Lightworks Pro.

When I export my edit to (AVI: Matrox YUYV, Matrox Mpeg, YUYV, DVCPRO and MOV: DVCPRO, UYVY and some of the others) only Audio plays in the final rendered video when I play it back, why is this?

If you are checking back your exports in Windows Media Player, it is highly unlikely it has the codecs available to play the exported video. We would recommend downloading VLC media player from here: https://www.videolan.org/vlc/ This is a free media player that supports most codecs.

Licensing

I purchased Lightworks Pro, can I use my license on Windows, Linux or Mac?

When you purchase a Lightworks Pro license you can decide whether to activate a Windows, Linux or Mac system.

Can I use my Lightworks Pro license on more than one system?

When you purchase a Lightworks Pro license you can decide whether to activate a Windows, Linux or Mac system.

My system crashed and I had to reinstall the Operating System. Will I lose my Lightworks Pro license for this system?

You will only lose the license file locally on the system. Install Lightworks and sign in with your Username and Password you will then be issued with the same license file again. If you receive an error or your Lightworks Pro license is not restored correctly, please fill in the form provided here: https://lwks.com/report-a-problem telling us the name of the system Lightworks Pro should be applied to, along with any other relevant changes to the system.

I want to move my Lightworks Pro Licence to another system - How can I do this?

This is currently not possible with the latest version of Lightworks and the new ELS licensing service. When you purchase a Lightworks Pro (Year or Outright) license you will receive a complimentary Lightworks Pro activation that can be used on a different system. Once activated the Lightworks Pro license cannot be removed. This complimentary activation exists for this reason only.

I want to move my Lightworks Free licence to another system - How can I do this?

Does the Lightworks Pro Buy Outright license expire?

The Lightworks Pro Outright license does not have an expiry date and can be activated at any time. Once activated, the software will no longer need an internet connection and can be used indefinitely. The Lightworks Pro Outright license will work for the current release version which includes all minor version updates. When the next version is released a license upgrade will be required.

Will my projects created with Lightworks Free be compatible with Lightworks Pro when I upgrade?

Yes. Projects created with either version of Lightworks will be compatible.

Hardware

Where can I download the drivers for the Contour Shuttle Pro?

Please visit http://forum.contourdesign.com for the latest installer version.

What operating systems does the Shuttle Pro support?

Only Windows and Mac OS X. Some users report success getting the driver to work on Linux, please search our Forum for potential solutions.

I have installed the Shuttle Pro drivers on Windows but Lightworks does not see the device. How can I fix this?

Please make sure you have set the Contour Control Panel to the ‘EditShare Lightworks’ profile. This will target the Lightworks program core executable (named - ntcardvt.exe) at both the Windows 32 & 64-Bit default OS installation paths of:

  • 32-bit installation path > C:Program Files (x86)Lightworks
  • 64-bit Installation path > C:Program FilesLightworks
  • If you have installed Lightworks in a custom install path you will need to manually select the ntcardvt.exe in the install directory.

I have installed the Shuttle Pro drivers on Mac OS X but Lightworks does not see the device. 
How can I fix this?

Ensure you have the correct installer package for your Mac OS X release version.

I have installed the Shuttle Pro drivers and Lightworks is working with the Shuttle Pro but not all the functions are working as I expect, what is wrong?

You will need to load the appropriate keyboard mapping file from within Lightworks.

1. Open Lightworks, enter a current project or create a new one if one does not exist.
2. On the Lightworks ‘Tools’ bar, open the ‘Editor preferences’ panel at the bottom of the panel
3. On the Preferences panel choose ’Import’
4. Browse to the appropriate xx.prefs file for the operating system you are running, select it then press ‘OK’ to apply.

- Mac: LWKS Contour Shuttle Key Mapping_OSX.prefs
- Windows: LWKS Contour Shuttle Key Mapping_Win.prefs

Will my existing Shuttle Pro work with Lightworks?

Yes, as long as the driver is supported and you target the ntcardvt.exe in the install directory, it will work.

Miscellaneous

Am I entitled to pre-release Beta versions to test any bug fixes that may be applicable to me?

Yes. Please visit the Downloads page and either click the "Windows - Beta" or "Linux - Beta" or "Mac OS X - Beta" Download. Once you agree to the Terms and Conditions your account will be upgraded and you will have access to the latest Beta versions. Please try to contribute to the Beta program. Inactive users on the Beta program will be removed.

What type of system is required to run Lightworks?

Please see recommended system specs here: https://lwks.com/lightworks-tech-specs

I’ve got a feature request, should I post it on the forum 'Feature Requests' section or submit it to support?

Please post all Lightworks feature requests in the appropriate section of the Lightworks Forum. We welcome all feature requests and are happy to hear new ideas from users.

An Administrator in the Lightworks Forum asked me to 'zip up' and send the Lightworks Backup folder. 
Where is this folder stored?

For Windows: C:/Users/Public/Documents/Lightworks/Logs

For Linux: /home/USER ACCOUNT/Lightworks/Logs

For Mac OS X: /Users/USER ACCOUNT/Lightworks/Logs

How do I eliminate vertical tearing on single screen as well as dual screen setups?

Windows Aero needs to be enabled, not disabled, and Vertical Sync in the NVidia control panel needs to be on.

I see the audio meters moving within Lightworks but I do not hear any audio from the speakers. This was working correctly in ‘earlier versions’. What is different?

In version 11.1 onwards we have added hardware support for Blackmagic and AJA I/O devices. If the drivers for the Blackmagic or AJA device are installed, Lightworks will by default use the device for outputting audio, it will no longer use the on board sound device in the system. You can change whether Lightworks uses the Hardware I/O or System Audio in the System Settings panel on the project browser screen.

I have lost my edit, how do I get it back?

Do not worry, your edit is still in the project you just have to search for it and open it. Open the Content Manager Tool (fourth tool from the top of the toolbox) and select the "Edits" filter and open your edit. If you have many edits and you know the name of your edit you are trying to find, click the magnifying glass icon on the content manager, type the name of your edit into the Name section and click Search (making sure "Edits" is selected under "Contents" The content manager will change view to show all the searched for edits from within your project, double click your edit to open it to a viewer or click the viewer icon on the tile.

How do I enable the onscreen playback controls (console)?

To activate and deactivate the On-screen Console go to the Editor Preferences (Figure with Cog) on the Tool Bar (left of screen) > User Interface > Playback Controls and choose Global for the bottom Console bar or On Each Viewer for separated controls on each viewer. Choose None if you wish to remove any controls completely off the screen. Useful if you want a cleaner GUI and have the Lightworks hardware Console.

Can I use the videos created with Lightworks Free for commercial use?

You're welcome to use the Free version of Lightworks for commercial purposes, directly on YouTube and elsewhere.

How do I enable Lightworks across two or more monitors?

On Windows and Linux this can be done by clicking System Settings on the Project Browser screen and setting "Fullscreen window" to "No" You will then be able to resize the Lightworks application across all of your monitors.

On Mac OS X, Apple changed the way that apps behave on multi-screen setups when it released Mavericks (10.9). By default, applications aren't allowed to span monitors. You can override this behaviour by changing the 'Displays have separate spaces' setting - see here: http://www.macworld.co.uk/how-to/mac-software/tips-using-multiple-displays-os-x-mavericks-3493420/
