Matrix Pattern Generator — Terms of Use, Conditions & Engineering Disclaimer

PixelMatrix Video Engineering · Terms version 2026-10-09-v3 · Last updated October 9, 2026

Please read before using Matrix Pattern Generator. These Terms include engineering, intellectual-property, warranty, liability and responsible-use conditions.

1. Purpose and free use

Matrix Pattern Generator is provided as a contribution to the professional video, live-events, broadcast, audiovisual, LED, projection, display, calibration, production and education communities. It is currently provided completely free of charge for normal legitimate use.

Users may use it for personal, educational, professional, freelance, business, engineering-planning, testing, pre-production and training purposes.

Free to use does not mean free to copy. Free access does not place the application in the public domain and does not transfer ownership of its source code, interface, original test-pattern implementations, workflows, branding, documentation or other protected content.

2. Permission to use

Subject to these Terms, PixelMatrix Video Engineering grants a limited, non-exclusive, revocable permission to use Matrix Pattern Generator for legitimate purposes. No ownership interest or intellectual-property right is transferred.

3. Intellectual property

Original software, application logic, interface design, workflows, graphics, documentation, branding, text, pattern implementations and other original content are owned by or licensed to PixelMatrix Video Engineering and the developer(s), except where third-party material is identified.

Unless authorized in writing, users may not copy, clone, republish, sell, resell, sublicense, redistribute substantial portions, remove ownership notices, misrepresent authorship, circumvent access controls, or create a substantially copied product from protected application content.

4. Engineering-assistance tool only

Matrix Pattern Generator is a test-pattern, visualization and engineering-assistance tool. It is not an automated engineering authority, calibration certificate, compliance certification, safety approval, or substitute for qualified engineering judgment.

Before relying on any pattern or export in a real system, independently verify relevant resolution, aspect ratio, frame rate, color space, dynamic range, signal range, bit depth, chroma sampling, processing, scaling, display behavior, signal path and device configuration.

Verify with current manufacturer documentation. Test the physical system. Use appropriate measurement instruments where accuracy matters.

5. Color, HDR and browser limitations

Browser canvas rendering is display-referred and can be affected by operating-system color management, browser behavior, GPU processing, display profiles, scaling and hardware output settings. Selecting BT.709, BT.2020, DCI-P3, HDR10, HLG, bit-depth or chroma metadata in the interface does not guarantee that the physical signal leaving a computer is operating in that format.

6. Exports and codecs

Browser-native export availability depends on the browser and platform. Professional codecs and containers may require a separate native or FFmpeg-based backend. Users are responsible for validating exported files before production use.

7. Uploaded media and logos

Users are responsible for ensuring they have the legal right to upload and use any logo, image, video, trademark or other media. PixelMatrix Video Engineering does not grant rights to third-party materials uploaded by users.

8. Third-party standards and trademarks

References to standards, protocols, manufacturers, product names or technical terminology are for engineering identification and reference. Third-party trademarks and intellectual property remain the property of their respective owners. Reference does not imply sponsorship, certification, endorsement or manufacturer approval.

9. Accuracy and updates

The application may contain software defects, assumptions, approximations, outdated information, rendering differences or errors. Features may change between beta versions. Users must independently verify information that is important to a live show, installation, broadcast, safety decision or commercial deliverable.

10. Audio test generator, LTC and hearing safety

The application may generate spoken test audio, sine-wave test tones, other waveforms, white noise, pink noise and SMPTE LTC synchronization audio through the computer's audio output. These signals are intended for legitimate technical testing, synchronization checks and troubleshooting.

Start at a low monitoring level. Continuous tones, high-frequency tones, broadband noise and LTC can be uncomfortable and may damage hearing, headphones, loudspeakers or downstream equipment when used at excessive levels. LTC is a synchronization signal and should normally be routed to a suitable line/timecode input rather than monitored as program audio.

Browser-generated LTC timing and output level can be affected by the browser, operating system, audio interface, sample clock, buffering and downstream processing. Verify LTC with an appropriate decoder or receiving device before relying on it for production synchronization. Browser dBFS settings do not constitute a calibrated analog dBu output level.

Users remain responsible for safe monitoring levels, appropriate duration, correct routing and suitable equipment.

11. No warranty

Matrix Pattern Generator is provided “AS IS” and “AS AVAILABLE”, without warranties of accuracy, fitness for a particular purpose, uninterrupted availability, compatibility or error-free operation, to the maximum extent permitted by applicable law.

12. Limitation of liability

To the maximum extent permitted by applicable law, PixelMatrix Video Engineering and the developer(s) are not responsible for losses arising from reliance on the application, including equipment damage, incorrect setup, display or calibration errors, show failure, production delay, data loss, lost revenue, business interruption, client claims or replacement costs. Nothing in these Terms excludes rights or liabilities that cannot lawfully be excluded.

13. Responsible and lawful use

Use Matrix Pattern Generator lawfully, professionally and for constructive purposes. Do not use it to intentionally create unsafe systems, damage equipment or infrastructure, infringe intellectual property, falsify certification, attack the service, distribute malicious code or extract protected application data through abusive automation.

14. Local browser data

The application may use browser storage to remember acceptance of these Terms and other local settings. Clearing browser data, using private browsing, changing browsers or changing devices may require acceptance again.

15. Changes to the Terms

These Terms may be updated as the application develops. A major revision may require acceptance again. The version shown in the acceptance dialog identifies the Terms accepted by that browser/device.

16. Contact

Questions about the application, these Terms, technical corrections, intellectual-property concerns or permissions may be directed to PixelMatrix Video Engineering through pixelmatrixvideo.nl.

17. Final engineering principle

Plan with the tool. Verify the signal. Verify the manufacturer documentation. Test the physical system. Use professional judgment. Use it responsibly.
