Error Handling

Best Practices

Quality

• Use max mode for final deliverables and professional outputs
• Use eco mode for previews and batch processing
• Specify target bitrate for predictable file sizes
• Request 2-pass encoding for better quality at lower bitrates

Performance

• Set client timeout to minimum 10 minutes for video processing
• Use eco mode for faster turnaround on large batches
• Process shorter clips when testing settings

Compatibility

• H.264 is the most universally compatible codec
• WebM/VP9 offers better compression but less device support
• ProRes is ideal for editing workflows but creates large files
• Always test output on target devices/platforms
