Tips for Best Results

Start with medium compression to balance size and quality

Reduce resolution if file size is more important than quality

Use high compression for videos that don't need perfect quality

Keep original resolution for important or professional videos

Test different settings for optimal results

Consider your intended use case when choosing compression level

Higher bitrates preserve quality but increase file size
