Originally, I was trying to add a subtitle to
in.mkv
, but I keep encountering this error. When I add the subtitle to another MKV file, it works fine, so I believe the problem lies within.mkv
.

Troubleshooting


Output only video stream produce the same error :


ffmpeg -i in.mkv -map 0:v:0 -c copy out.mkv



Output only audio stream works fine :


ffmpeg -i in.mkv -map 0:a:0 -c copy out.mkv



Output as mp4 got no error, but the output file is unplayable :


ffmpeg -i in.mkv -c copy -strict -2 out.mp4



Re-encoding works fine :


ffmpeg -i in.mkv -c:v libx265 -c:a copy out.mkv



How can I fix the video stream in
in.mkv
so that I can add a subtitle stream and remux the file without re-encoding the video ? Any insights or suggestions on handling this error would be greatly appreciated.

A Primer to Ethical Marketing : How to Build Trust in a Privacy-First World
Imagine a marketing landscape where transparency replaces tactics, where consumer privacy is prioritised over exploitation, and where authentic value builds genuine relationships.
This isn’t just an ideal—it’s the future of marketing. And it starts with ethical marketing practices.
76% of consumers refuse to buy from companies they do not trust with their data. Ethical marketing has become essential for business survival. As privacy regulations tighten and third-party cookies phase out, marketers face a critical question : how can they balance effective, personalised campaigns whilst respecting privacy ?
This comprehensive guide explores what ethical marketing is, the key principles behind ethical marketing practices, and practical strategies to implement an ethical approach that builds trust while driving growth.
What is ethical marketing ? A comprehensive definition
Ethical marketing places respect for consumer boundaries at its core whilst delivering genuine value. It prioritises transparent practices, honest communication, and fair value exchange with consumers. This approach represents a significant shift from traditional marketing, which often relied on collecting vast amounts of user data through invasive tracking methods and obscure policies.
The modern approach to ethical marketing creates a foundation built on three key pillars :
- User Control : Giving people genuine choice and agency over their data
- Fair Value : Providing clear benefits in exchange for any data shared
- Transparency : Being honest about how data is collected, used, and protected
Key principles of ethical marketing
Transparency
Transparency means being clear and forthright about your marketing practices, data collection policies, and business operations. It involves :
- Using plain language to explain how you collect and use customer data
- Being upfront about pricing, product limitations, and terms of service
- Disclosing sponsored content and affiliate relationships
- Making privacy policies accessible and understandable
When Matomo surveyed 2,000 consumers, 81% said they believe an organisation’s data practices reflect their overall treatment of customers. Transparency isn’t just about compliance—it’s about demonstrating respect.
Honesty
While similar to transparency, honesty focuses specifically on truthfulness in communications :
- Avoiding misleading claims or exaggerations about products and services
- Not manipulating statistics or research findings to support marketing narratives
- Representing products accurately in advertisements and marketing materials
- Acknowledging mistakes and taking responsibility when things go wrong
Social responsibility
Ethical marketing requires consideration of a brand’s impact on society as a whole :
- Considering environmental impacts of marketing campaigns and business practices
- Promoting diversity and inclusion in marketing representations
- Supporting social causes authentically rather than through “purpose-washing”
- Ensuring marketing activities don’t promote harmful stereotypes or behaviours
Ethical marketing dilemmas : Navigating complex business decisions
Data privacy concerns
The digital marketing landscape has been transformed by increasing awareness of data privacy issues and stricter regulations like GDPR, CCPA, and upcoming legislation. Key challenges include :
- The phase-out of third-party cookies, impacting targeting and measurement
- Growing consumer resistance to invasive tracking technologies
- Balancing personalisation with privacy (71% of consumers expect personalised experiences, yet demand privacy)
- Ensuring compliance across different jurisdictional requirements
Cultural sensitivity
Global brands must navigate complex cultural landscapes :
- Avoiding cultural appropriation in marketing campaigns
- Understanding varied cultural expectations around privacy
- Respecting local customs and values in international marketing
- Adapting messaging appropriately for diverse audiences
Environmental sustainability
The environmental impact of marketing activities is under increasing scrutiny :
- Digital carbon footprints from ad serving and website hosting
- Waste generated from physical marketing materials
- Promoting sustainable products honestly without greenwashing
- Aligning marketing messages with actual business practices
The benefits of ethical marketing
For years, digital marketing has relied on third-party data collection and broad-scale tracking. However, new regulations such as GDPR, CCPA, and the end of third-party cookies are pushing brands to adopt ethical data practices.
Increased customer loyalty
Ethical marketing fosters deeper relationships with customers by building trust. Research consistently shows that consumers are more loyal to brands they trust, with 71% indicating they would stop buying from a brand if trust is broken.
These trust-based relationships are more resilient during business challenges. When customers believe in a company’s integrity, they’re more likely to give the benefit of the doubt during controversies or service issues. They’re also more likely to provide constructive feedback rather than simply leaving for competitors.
Perhaps most importantly, loyal customers become advocates, sharing positive experiences with others and defending the brand against criticism. This organic advocacy is far more powerful than paid promotions and reduces customer acquisition costs significantly over time.
Enhanced brand reputation
A strong ethical stance improves overall brand perception across multiple dimensions. Media outlets are increasingly focused on corporate behaviour, providing positive coverage for ethical practices that extends a brand’s reach organically.
Social conversations about ethical brands tend to be more positive, with consumers sharing experiences and values rather than just discussing products. This creates a halo effect that benefits all aspects of the business.
This enhanced reputation also provides resilience during public relations challenges. Organisations with strong ethical foundations find it easier to navigate controversies because they’ve built a reservoir of goodwill with customers, employees, and other stakeholders.
Competitive advantage
Ethical marketing provides several distinct competitive advantages in modern markets. It helps brands access privacy-conscious consumer segments that actively avoid companies with questionable data practices. These segments often include higher-income, educated consumers who are valuable long-term customers.
Ethical approaches also reduce vulnerability to regulatory changes and potential penalties. As privacy laws continue to evolve globally, organisations with strong ethical foundations find compliance easier and less disruptive than those scrambling to meet minimum requirements.
Perhaps most significantly, ethical marketing supports more sustainable growth trajectories. While manipulative tactics might drive short-term results, they typically lead to higher churn rates and increasing acquisition costs. Ethical approaches build foundations for long-term success and stable growth.

Strategies for implementing ethical marketing
Aligning marketing efforts with brand values
Consistency between values and actions is essential for ethical marketing. This alignment starts with a clear understanding of what your organisation truly stands for—not just aspirational statements, but genuine commitments that inform daily decisions.
Implementing this alignment requires cross-functional collaboration. Marketing teams need to work closely with product development, customer service, and leadership to ensure consistency across all touchpoints. When different departments send contradictory messages about company values, trust erodes quickly.
Clear guidelines help marketing teams apply values in practical decisions, from campaign concepts to media placements. Regular ethical reviews of marketing plans can identify potential issues before campaigns launch, avoiding reactive corrections that damage credibility.
Privacy-first data strategies
Developing robust approaches to customer data is fundamental to ethical marketing. This starts with prioritising first-party data (collected directly from your own channels) and zero-party data (actively shared by customers through preference centres, surveys, and similar mechanisms).
Measuring success doesn’t have to come at the expense of privacy. Ethical analytics provide accurate insights while protecting user data, ensuring compliance, and enhancing customer trust.
Ethical personalisation approaches focus on using aggregated or anonymised data rather than individual tracking. This allows for relevant experiences without the invasive feeling that erodes trust when consumers feel watched across the internet.
Most importantly, ethical data strategies create transparent value exchanges where users clearly understand what benefits they receive in return for sharing information. This reciprocity transforms data collection from exploitation to fair exchange.
Measuring success ethically
Traditional marketing measurement often relies on individual-level tracking across sites and platforms. Ethical approaches require adapting these frameworks to respect privacy while still demonstrating impact.
Focusing on aggregate patterns rather than individual behaviour provides valuable insights without privacy invasions. For example, understanding that 30% of visitors to a specific page subsequently make purchases is actionable intelligence that doesn’t require tracking specific people.
Incrementality testing measures campaign impact by comparing outcomes between exposed and control groups at an aggregate level. This provides more accurate attribution than traditional last-click models while respecting privacy boundaries.
Server-side conversion tracking offers another ethical measurement approach, collecting necessary data on your servers rather than through client-side scripts vulnerable to blocking. This improves data accuracy while reducing reliance on cookies and browser storage.
Implementing ethical marketing strategies : A practical framework
1. Align marketing with brand values – Ensure campaigns reflect transparency and trust
2. Leverage first-party data – Collect insights directly from consumers with clear consent
3. Respect privacy and consent – Give users control over their data and clearly communicate its use
4. Create value-driven content – Offer educational and relevant resources instead of relying solely on advertising
5. Use privacy-compliant analytics – Switch to ethical platforms such as Matomo for responsible performance measurement

The future of ethical marketing
With the decline of third-party cookies and the rise of privacy regulations, ethical marketing is no longer optional. Brands that adopt privacy-first practices now will gain a sustainable competitive edge in the long term. The future of marketing belongs to brands that earn consumer trust, not those that exploit it.
Key trends shaping the future of marketing include :
- Privacy-first analytics to replace invasive tracking
- First-party and zero-party data strategies for direct consumer engagement
- Consent-driven personalisation to balance relevance and privacy
- Greater emphasis on corporate social responsibility in marketing initiatives
Companies that proactively address these changes will build stronger customer relationships, enhance brand reputation, and ensure long-term success.
