Installation

How do I update Lightworks to the latest version?

This is a very simple process and one that requires you to just install the latest version of Lightworks into the same directory you installed the original version. By default Lightworks is installed here:

  • Windows: C:/Program Files/Lightworks
  • 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?

Windows: You can uninstall Lightworks using the Uninstall function in Control Panel->Uninstall a Program. Simply select Lightworks and click Uninstall.

Linux Debian distros: Open a Terminal window and type: sudo apt-get remove lightworks

Linux RPM distros: Open a Terminal Window and type: dnf remove lightworks (you will need to have the correct system privileges for this to work)

Mac: Drag the Lightworks.app to the Bin

When I attempt to install the Linux version I receive an error: AMD64 What does this mean?

This error message suggests you are trying to run the Linux Lightworks 64bit installer on on a 32bit system. (amd64 is the official name of 64bit systems, which Ubuntu uses) Only 64bit Linux systems are supported. There are currently no plans to produce a 32bit version of Lightworks for Linux on 32bit systems.

Startup

Lightworks fails to start, what can I do?

There are several things to check with regards to Lightworks not starting:

1. Make sure you are running the latest version of Lightworks (2021.2 or higher) from the Downloads page.

2.That the graphics card drivers are installed and working correctly. Please make sure that a "standard VGA" driver is NOT installed.

3. That the sound card is installed and working correctly, ie, you can hear audio coming from the system. Please make sure that speakers/headphones are connected and that the audio is enabled.

4. Intel 945/G33/G31 graphics chipsets are no longer supported. If you have one of these graphics cards, please upgrade it to resolve this issue.

5. That your DirectX is up to date. Please download the DirectX End-User Runtime Web Installer from here: https://www.microsoft.com/en-us/download/details.aspx?id=35

6. If you are running Windows Defender, please disable it and reinstall Lightworks.

Lightworks will not start and reports that d3dx9_43.dll is missing from the system. How do I resolve this?

This error means that the DirectX drivers on your system need updating. To resolve the issue download the DirectX End-User Runtime Web Installer from here: https://www.microsoft.com/en-us/download/details.aspx?id=35

In order to start using Lightworks you will first need to have registered an account with us here: https://app.lwks.com/sign-up Once your account is registered successfully, you can use your Username/Email and Password to sign in to the Lightworks application.

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 720p. In order to export at higher resolutions you will need to upgrade to either Lightworks Create or Pro. Please visit this page: https://lwks.com/lightworks-comparison/ to compare Lightworks Free, Create and 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.

There you will see purchase options for regular upgrade and upgrade plus TotalFX.

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.

NewBlue Plugins

What are the minimum specs required for Titler, Transitions, Essentials and TotalFX?

This info can be found on the Lightworks Tech Specs page

Which Lightworks license types support TotalFX?

The TotalFX package requires Lightworks Pro.

I have Lightworks and TotalFX installed but cannot see the effects in the Plugins category

This is most likely due to an older version of Lightworks being installed. Please update to the latest version of Lightworks 2022.1 or higher.

Miscellaneous

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

Yes. Please visit https://app.lwks.com/downloads/lightworks/beta read the terms and click the button to agree to join the Beta testing.  This will upgrade your account to give you access to the Beta downloads

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/

I can sign in to www.lwks.com, but the software still says "Unknown username/password - please try again"
Double-check the credentials using the method above. The password field should accept all characters, however there may be exceptions - try resetting the password:
www.lwks.com/reset-password
I have confirmed that the sign in details are correct, but Lightworks says "Cannot connect to licensing server". It offers me 'offline activation' only.
Connection issues are caused by a break in the communication between your computer and the licensing server. This break can be caused by a variety of things, including your router, firewall, anti-virus, local network and internet service provider.

Test your connection to the activation server - see the following entry:
'How to test your connection to the activation server'.
How to test your connection to the activation server
In your web browser visit https://els.lwks.com/test

This test page will confirm whether or not your computer is allowed to communicate with the licensing server, connecting through port TCP/443.

Possible results:

1. I see a message similar to "404 - Server not found".
We work hard to ensure that the licensing server is always accessible. If the server cannot be found it's likely that the problem is ‘local' (specific to your computer/network/internet service).

Check your internet connection. If the connection is working but the test page is not found, there might be a problem with your DNS service, or your computer might be connecting to the internet via a Proxy server (which in turn might have DNS problems or restrictions).

Recommendations:

- Flush your local DNS
Guide: www.whatsmydns.net/flush-dns.html

- Change your DNS server
Try setting your modem/router to use an alternative DNS service, such as Google DNS or OpenDNS: www.opendns.com

- OS specific instructions
Windows
Linux (Ubuntu)
Mac OS X


2. I see a message similar to "You can't access this page, contact network administrator".

This indicates that a local firewall restriction is stopping access to els.lwks.com on TCP port 443

Your firewall might be managed by your operating system or by your AntiVirus software. Please refer to the appropriate documentation.

OS specific instructions
Windows 7
Windows 8
Linux
Mac OS X

3. The test page https://els.lwks.com/test won't load or is timing out:

Set your web browser to visit www.lwks.com

A. If www.lwks.com is also timing out your IP address may have been blocked by our firewall, you can confirm this by checking from another IP (either another computer or via a proxy).

To resolve the problem contact us at webteam@lwks.com quoting your IP address which can be checked at: whatsmyip.org

B. If www.lwks.com works but https://lwks-devsite.onyx-sites.io does not - this suggests that local firewall rules for port TCP/443 are incorrect (see setting your firewall rules above), OR the activation server els.lwks.com is blocked by your ISP or Proxy Server - contact your network administrator.

4. The test page confirms that I can connect, but the software still won't activate:

Please zip up the Lightworks log files from:

- Windows: C:UsersPublicDocumentsLightworksLogs
- Linux and Mac OS X: ~/Lightworks/Logs

Send the zipped files to contact@lwks.com with your lwks.com username

What is QScan?

QScan is an Automated Quality Control Solution.

- QScan does not require internet connection (only needed for the online activation)

- Preferred browser is Chrome.

Using QScan you can select files to be checked, against a set of parameters (a parameter 'template').

Which type of QC does QScan perform on the A/V content?

QScan performs an analysis of the technical characteristics, format parameters and the perceptual quality of media content. QScan focuses on the verification of formats, metadata (such AS-11 metadata information) and the effects and artefacts resulting from successive manipulations of the content, such as black frames, freezing, video levels, audio silence, etc. Also allows to verify compliance to international standards, such as IMF or DCP packages, and now HDR measurements for MaxFALL and MaxCLL verification.

What differentiates QScan from other products?

QScan presents a whole new set of unique features, such as Single Pass Analysis, Comparative Analysis, Macros, unique visual IMF representation, HDR measurements, and more. These features, combined with the easy visual UI, and the new flexible payment model, makes QScan the most affordable, fuly featured and user friendly AQC in the market. AQC will never be limited to Pro users with the new monthly, yearly or outright licenses with different flavors to adapt to any budget. The only AQC in the world that you can get for FREE. Democracy has finally arrived to the AQC world.

What are the main advantages of QScan over other QC titles?

The new GUI reduces the complexity of a very technical task as the Quality Control

  • New ready made templates according to industry delivery specifications, for ease of use, even in the Free version.
  • Single Pass Analysis, that allows to update results in just a matter of second when changing thresholds (quality criteria) in the project configuration.
  • Compliance with worldwide technical standards
  • Avoid long and inefficient QC processes based on human intervention
  • Macros allow users to create their own customized quality thresholds (conditions) such as “identify only black frames that also have audio silence”
  • QC speed faster than real-time
  • Availability of an API for integration into third-party applications
  • Modular, scalable architecture with simple load balancing
  • Based on web technology
  • New Comparative Analysis that allow to compare different versions of the same file and seek for quality differences
  • HDR analysis compliant to all existing HDR standards, and with advanced video measurements
  • IMF Package support.

Why do I need to automate QC?

If you are a content producer, broadcaster, etc., the automation of content QC will enable you to minimize manual QC, saving significant investment in time and resources. Human inspection (i.e. 'eyeballing') is not capable of detecting or providing an objective measurement of all errors or artefacts that exist in the content.

In which languages is QScan available?

QScan is available in English, although it does support the UNICODE standard for extended character sets (Korean, Japanese, Chinese, etc.). By using translation files, QScan can currently be adapted to any other language. Available translation files can be downloaded from the Settings/System menu option in QScan.

Does QScan make use of GPUs (graphics processing units, Nvidia for example) for the processing?

QScan solely makes use of the CPU.

GPU use is in our roadmap and it is expected to be available by Q2 2022.

I need to QC a high volume of files. Can QScan address that?

Yes. QScan MAX can process 4 files concurrently per server (node). You can expand beyond 4 by setting up additional MAX nodes. Contact sales@lwks.com for further information.

What are the minimum and recommended Hardware Specifications for QScan?

QScan requires a Windows machine - version 7 and newer, including Server versions. This machine can also be virtual, running on Mac / Linux.

The interface can be accessed locally via a web browser (Chrome recommended). It can also be accessed remotely, from any machine on your network, running any OS and web browser.

Recommended for optimal speed (Real Time speed) up to 4 files at a time per QScan machine: - 16 core machine - Minimum 8GB of RAM - 1TB HDD: will depend on whether QScan machine is also used for the content storage.

Optimally SDD in RAID configuration. - 1GbE ports NOTE on Ethernet ports: the bitrate of the files that are to be QC'ed needs to be considered.

The required ethernet speed will depend on the file bitrate, the amount of simultaneous files, and the expected analysis speed. I.e: if we want to analyze 4 ProRes@220Mbps, 2 times faster than real time, and we do not want the networks to be the bottleneck, the network speed should be 4x220x2=1760Mbps (1.7Gbps)

You can check the HW requirements in our HW guideline document that can be downloaded from here: https://app.lwks.com/downloads/documentation

Which web browsers enable working with QScan?

QScan may be executed from any browser, however, the recommended browser is Google Chrome.

Does QScan work in a Virtual Machine Environment?

QScan may be executed on virtual machines. It is merely necessary to ensure that the virtual machine is configured to have access to the network shares that need to be accessed to read the files (if any). QScan has been tested in VM environments such as VMWare, Virtual Box, Parallels, Hyper-V. Please contact us to know more about supported VM environments.

Can QScan be used with Linux or MAC OS?

QScan cannot be executed natively in these operating systems, it is compatible with MAC through a virtual machine or Boot Camp and with Linux through a virtual machine.

Can QScan be integrated into third-party systems?

Yes, QScan has its own API which enables integration of the QC in third-party systems such as: ingest systems, encoders, transcoders, MAMs, playout systems, correction systems, etc. The API is fully documented. For more information, please contact sales@lwks.com

I don´t know the size of the QScan system I should use, can you recommend?

The first question to answer is: how many hours of analysis will be needed per day (or week, month)? As a 'worst case' scenario, if we assume that QScan can analyze at Real Time Speeds (that is true up to HD resolutions), 1 simple license of QScan (1 file at a time) would be capable of analyzing 24 hours of material in a day, thus the basic license consisting of 4 files at a time, will be capable of analyzing 96 hours per day, assuming 24x7 use, and that the HW and network are enough for those speeds.

Taking this as the bottom line, the faster the machine, the bigger the amount of content that could be analyzed per day. So, if we aim at analyzing 125 hours of content per day, 125/24=5,21 files at a time (considering 24x7 operation). So, it would be necessary to analyze more than 5 files at a time. Thus needing additional worker nodes. NOTE: performance can vary depending on the Hardware, file formats, file bitrate, parameters to be analyzed, etc. Heavy file exchange formats (DNxHD, ProRes, XAVC, J2K, etc) might take longer than traditional broadcast formats (MPEG2, H264, HEVC, etc).

Does LWKS supply hardware?

LWKS does not provide Hardware to be used with QScan. You can see the recommended minimum requirements in the download page https://app.lwks.com/downloads/documentation

What support or assistance will I receive?

Operation

Which parameters does QScan analyze?

QScan analyzes different types of parameters:

  • Format Parameters: assure that you will deliver with the right format
  • Perceptual quality parameters: avoid artefacts in your video or audio, missing audio and a whole set of other problems
  • MXF metadata
  • IMF packages integrity
  • Audio loudness
  • and now with HDR measurements of MaxFALL, MaxCLL and gamut!

You can see a complete list of parameters on the QScan Tech Specs page https://lwks.com/qscan-tech-specs

Can QScan perform the QC of files which only contain audio?

Yes, although QScan is designed to perform the simultaneous analysis of audio and video, it is possible to configure the analysis solely for audio. Likewise, in the configuration process for QC projects it is possible to choose solely audio QC.

How many audio channels is it possible to analyse with QScan?

QScan can analyze up to 16 audio channels simultaneously. It is possible to analyse mono, stereo, 5.1 and 7.1 audio channels.

How long will QScan take to carry out a full QC analysis of a file?

This will depend on various factors such as the speed of your CPU and the file formats to be analyzed. It is recommended that i7 or superior processors be used for QC tasks. We currently possess benchmarks achieved using different processors and different file formats. As a reference, it may be indicated that a 10 minute XDCAM HD file would take 6 minutes to analyse using an i7 processor and 4GB RAM.

Check out the HW Guidelines documentation that can be downloaded from the download page: https://app.lwks.com/downloads/documentation

Is it possible to prioritize files?

Yes, QScan allows you to set analysis priority 'per file' and 'per project'. There are three levels of priority (High, Normal, Low).

Can QScan be configured from different time zones?

QScan can be configured to any time zone.

Apart from detection, does QScan do any corrections to the content?

No, QScan only does analysis of media files. No correction is included in any of the license options.

Can QScan do compliance checking?

Yes, QScan complies to most adopted standards. These include: AMWA, DPP, SMPTE, etc. QScan also provides a complete set of ready made templates that comply to most industry delivery specifications, to guarantee that your content will be accepted by major companies such as Netflix, Amazon, iTunes, etc.

Does QScan enable the analysis of live sources?

No. QScan is not a monitoring tool, but rather an Automated Quality Control tool intended for file based content.

What happens if I want to analyze a very large file?

QScan has been tested with very large files. File size will only impact on the time that is needed to perform the analysis. Furthermore, QScan Max enables workload to be distributed across multiple nodes (or QC servers). The 'Partial Analysis' feature enables you to analyze files in chunks of the selected duration, and thus processor load can be distributed across multiple nodes.

What learning resources are available for QScan?

The 'Getting Started' document describes the first steps https://app.lwks.com/downloads/documentation

Check out the QScan "hints and tips" category in the forum. We periodically post new entries aimed at helping you getting the best out of QScan https://forum.lwks.com/forums/hints-tips.601/

How do I ensure that the files reach QScan in order for it to work with them?

The files to be analyzed in QScan must be available in the local drives or the repositories which are configured in the initial system configuration (Only Pro and Max). These files may be on the local machine where QScan is located or in folders on the workplace LAN.

In order to create repositories: Settings > Repositories > Create Repository.

When subsequently creating a project, watch folders would be selected within the available repositories.

Check out the hints and tips entry in the forum https://forum.lwks.com/threads/configuration-of-repositories.243594/

How many different templates can I have?

The number of templates which can be used in QScan depends on your license.

  • QScan Free: only Vimeo, YouTube and 3 custom made templates
  • QScan One: Vimeo, YouTube, some additional default templates, and up to 10 custom made templates
  • QScan Pro: all default templates and unlimited custom made templates
  • QScan Max: all default templates and unlimited custom made templates.

Does QScan support the analysis of growing files?

Growing files would never work for all file formats, since not all of them allow reading the file before it is complete. So, QScan does not support growing files. Files need to be completely copied to a folder accessible by QScan prior to the analysis. QScan will detect the file even if it still being copied, but the analysis will not start until the file copy/move is complete.
