Quality Preservation Tips

1. Avoid Multiple Conversions

Each conversion can lose quality. Convert from the highest quality source.

2. Match Resolution

Don't upscale - converting 720p to 1080p doesn't improve quality.

3. Choose Appropriate Bitrate

• Web sharing: 5-8 Mbps
• High quality: 10-20 Mbps
• Professional: 50+ Mbps

4. Consider Your Audience

• Mobile viewers: MP4 with moderate bitrate
• Desktop users: Higher quality acceptable
• International: MP4 for maximum compatibility
