Verify sync before and after processing
Adjust audio timing in video editor if needed

Prevention:

Use consistent frame rates throughout workflow
Test audio sync on short clips first
Backup original audio before processing

Problem: File Size Too Large

Symptoms: Output files are excessively large, difficult to manage

Causes:
