1. What is YouTube Video Resolution?

YouTube video resolution, as defined by Andrew Hedges, is calculated by multiplying the width and height of a video in pixels. This gives the total number of pixels in each frame of the video.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( yt\_res \) — Total resolution in pixels
• \( video\_width \) — Width of video in pixels
• \( video\_height \) — Height of video in pixels

Explanation: The equation simply multiplies the width and height dimensions to get the total pixel count.

3. Importance of Video Resolution

Details: Video resolution affects both quality and bandwidth requirements. Higher resolution means better quality but requires more bandwidth and storage space.

4. Using the Calculator

Tips: Enter video width and height in pixels. Both values must be positive integers representing valid video dimensions.

5. Frequently Asked Questions (FAQ)

Q1: What are common YouTube resolutions?
A: Common resolutions include 426×240 (240p), 640×360 (360p), 854×480 (480p), 1280×720 (720p HD), 1920×1080 (1080p Full HD), and 3840×2160 (4K UHD).

Q2: Does higher resolution always mean better quality?
A: While higher resolution generally means better quality, other factors like bitrate, codec, and compression also affect perceived quality.

Q3: How does resolution affect file size?
A: Higher resolution videos have more pixels and therefore typically result in larger file sizes, though compression can mitigate this.

Q4: What's the relationship between resolution and aspect ratio?
A: Aspect ratio is the width-to-height ratio (e.g., 16:9), while resolution is the absolute pixel dimensions (e.g., 1920×1080).

Q5: Can I upload any resolution to YouTube?
A: YouTube accepts a wide range of resolutions, but recommends using standard resolutions and aspect ratios for best results.
