Mastering Compression and Bitrate
Understanding bitrate and compression is crucial for balancing file size with quality. The right settings depend on your content type, target audience, and delivery platform.
Bitrate Guidelines by Resolution
Standard Video Content (30fps)
High Motion Content (Sports, Gaming)
Increase bitrates by 50-100% for content with rapid movement
Compression Types
Constant Bitrate (CBR)
- • Predictable file sizes
- • Good for streaming
- • May waste bandwidth on simple scenes
- • Consistent quality across content
Variable Bitrate (VBR)
- • Optimizes quality per scene
- • Better overall quality
- • Unpredictable file sizes
- • Preferred for final delivery
Quality vs Size Balance
Low Quality
Visible compression artifacts, blocky motion, poor detail
Balanced
Good quality-to-size ratio, minimal visible artifacts
High Quality
Excellent detail, large file sizes, professional grade
Platform-Specific Optimization
Each social media platform and streaming service has unique requirements and recommendations for optimal video performance. Tailoring your settings to each platform ensures the best possible user experience.
