Prompt

Create a comprehensive, research-based reference of video types, grouped into practical categories and presented in a Markdown (.md) table. Also create a PDF version of the same research. GOAL I want to understand the major types of videos that are actually produced and used in the real world across film, television, advertising, marketing, business, social media, education, journalism, entertainment, events, technology, and other relevant fields. Do NOT simply generate a list from general knowledge. The information must be researched, verified, and evidence-based. 1. VIDEO TYPES TO INCLUDE Start with established examples such as: - YouTube videos - Instagram Reels - Short films - TV commercials / TV ads - Corporate videos - Customer testimonial videos - Documentaries - Music videos - Film trailers Then identify and add other established video types that belong in the relevant categories. Do not invent new video categories or create artificial names just to make the list longer. If two terms are essentially the same established format, explain the relationship instead of unnecessarily treating them as separate video types. 2. GROUP THE VIDEO TYPES Organize the research into logical categories. Possible categories include: 1. Advertising & Commercial 2. Corporate & Business 3. Social Media & Creator Content 4. Film & Entertainment 5. Documentary & Factual 6. News & Journalism 7. Educational & Training 8. Product & Technology 9. Marketing & Brand Content 10. Events & Live Content 11. Personal & Community 12. Sports 13. Music 14. Government & Public Information 15. Real Estate & Property 16. Healthcare 17. Travel & Tourism 18. Internal Communication 19. Recruitment & Employer Branding 20. Other established professional formats Do not force a video type into a category if the classification is unclear. Explain overlapping categories where necessary. 3. INFORMATION REQUIRED FOR EACH VIDEO TYPE Create a table containing, where reliable information is available: | Category | Video Type | Typical Duration | Primary Purpose | Common Use / Platform | Typical Audience | Key Characteristics | Example / Context | Evidence Level | For each video type, research: - Typical duration - Primary purpose - Where it is commonly used - Typical audience - Key characteristics - Practical examples or contexts IMPORTANT: Do NOT invent a duration. Video duration often varies substantially by purpose, platform, audience, and production context. If there is no accepted standard duration, write: "No fixed standard" If reliable sources provide a range, give the range and explain what it represents. Clearly distinguish between: - Industry practice - Platform limits - Platform recommendations - Common creator practice - Traditional broadcast standards - Common advertising formats Do not present a platform maximum as if it were the normal production length. 4. RESEARCH REQUIREMENTS Before producing the final table, conduct REAL WEB RESEARCH. Use multiple types of reliable sources. A. OFFICIAL SOURCES Where applicable, prioritize: - Official platform documentation - Official broadcaster information - Official film/television organizations - Official industry organizations - Government or institutional sources - Professional associations Examples include official resources from platforms such as YouTube, Instagram/Meta, TikTok, LinkedIn, Vimeo, etc., when relevant. B. MAJOR MEDIA & INDUSTRY PUBLICATIONS Research established media and industry publications, including relevant sources such as: - Major media publications - Film and television publications - Advertising industry publications - Marketing publications - Production industry publications - Journalism organizations - Technology publications - Professional creator/production publications Use the most authoritative source available for each claim. C. PROFESSIONAL / EDUCATIONAL SOURCES Where useful, consult: - Film schools - Universities - Journalism schools - Professional training organizations - Established production companies - Recognized industry bodies - Academic publications D. FORUMS & REAL-WORLD DISCUSSIONS Also research relevant forums and communities to understand how these formats are actually used in practice. For example: - Reddit discussions - Professional filmmaking communities - Creator communities - Video-production forums - Marketing communities - Cinematography communities - Editing communities Use forum discussions to identify real-world experiences, common practices, practical problems, and variations. However: DO NOT treat forum comments as authoritative evidence for factual claims when stronger sources are available. Clearly distinguish: - Verified industry information - Professional practice - Common community experience - Individual opinions 5. NO FABRICATION RULE This is extremely important. DO NOT fabricate, guess, infer, or make up: - Video types - Industry terminology - Durations - Platform limits - Purposes - Audience information - Production practices - Statistics - Industry standards - Examples - Source claims If reliable evidence cannot be found, write: "Reliable source not found" or omit the claim. Do not fill missing information with what "sounds reasonable." 6. CONFLICTING INFORMATION If reliable sources disagree: 1. Do not silently choose one. 2. Show the difference. 3. Explain why the numbers or definitions differ. 4. Identify the source and context. For example: A platform may allow videos up to X minutes, while industry sources describe a much shorter duration as common for that particular format. Always distinguish MAXIMUM ALLOWED DURATION from TYPICAL PRODUCTION DURATION. 7. DURATION RULES Duration is one of the most important fields. Do not assume that every format has a standard duration. Use descriptions such as: - Typical: X–Y minutes - Common: X–Y seconds - Often under: X minutes - Variable: depends on subject/purpose - No fixed standard - Platform-dependent - Broadcast-standard duration, where applicable Whenever possible, explain WHY the duration varies. 8. EVIDENCE LEVEL Add an Evidence Level column. Use only these labels: - HIGH — supported by official documentation, established industry organizations, or multiple authoritative sources - MEDIUM — supported by credible industry/professional sources but less standardized - PRACTICAL / OBSERVED — supported mainly by professional or community discussions - UNCERTAIN — evidence is insufficient or conflicting Do not give a HIGH evidence rating simply because a claim appears on one random website. 9. SOURCES & CITATIONS Every important factual claim should have a source. Include citations directly in the Markdown document. At the end, create a SOURCES & REFERENCES section containing: - Source name - Publication/organization - Page/article title - Date, where available - URL - What the source supports Prefer PRIMARY SOURCES whenever possible. For forum sources, identify them clearly as COMMUNITY / REAL-WORLD EVIDENCE. 10. SEPARATE FACTS FROM PRACTICE Clearly distinguish between: ESTABLISHED DEFINITION What the format officially or academically means. INDUSTRY PRACTICE How professionals commonly use the format. PLATFORM PRACTICE How a particular platform defines, limits, or recommends the format. REAL-WORLD PRACTICE What creators, filmmakers, editors, marketers, or other professionals report doing. Do not merge these into one unsupported statement. 11. COMPREHENSIVE BUT PRACTICAL The objective is NOT to create the longest possible list. The objective is to create a useful reference that covers the major established video formats without padding the list with questionable or invented categories. Include a video type when there is credible evidence that it is an established format, production type, or commonly recognized use case. Avoid: - Invented terminology - Duplicate categories - Meaningless variations - Unsupported duration numbers - SEO-generated lists with no credible evidence - Unnecessary platform-specific duplication 12. FINAL DELIVERABLES Produce TWO files: FILE 1 — MARKDOWN Filename: comprehensive_video_types_reference.md It should contain: 1. Title 2. Research methodology 3. Important terminology/definitions 4. Main categorized table 5. Notes on duration 6. Notes on overlapping categories 7. Evidence-level explanation 8. Key findings 9. Sources & References 10. Research limitations FILE 2 — PDF Filename: comprehensive_video_types_reference.pdf The PDF must contain the SAME SUBSTANTIVE INFORMATION as the Markdown version, formatted for easy reading. Use: - Clear section headings - Readable tables - Page numbers - Source references - Consistent formatting - Landscape pages for wide tables where necessary 13. QUALITY-CONTROL CHECKLIST Before finalizing the files, verify: - [ ] Every video type is an established term or clearly documented format. - [ ] No category was invented merely to increase the number of entries. - [ ] No duration was guessed. - [ ] Typical duration is not confused with maximum platform duration. - [ ] Conflicting information is identified. - [ ] Major factual claims have sources. - [ ] Primary/official sources are preferred where available. - [ ] Major media and industry sources were researched. - [ ] Relevant forums were researched for real-world experience. - [ ] Forum opinions are not presented as universal facts. - [ ] Duplicate or overlapping video types are handled carefully. - [ ] The information is practical and useful for someone working with video production. - [ ] Markdown and PDF contain the same substantive research. - [ ] No unsupported claims have been added simply because they seem plausible. MOST IMPORTANT RULE: If reliable evidence does not support a claim, DO NOT make the claim.
