Best Practices

最佳实践

Trimming Tips

修剪技巧

  • Be specific: Provide exact timestamps (MM:SS or HH:MM:SS) when possible
  • Describe content: If you do not know timestamps, describe what you want ("the part where they shake hands")
  • Buffer time: Allow small buffers around cuts to avoid abrupt transitions
  • Check audio: Ensure cuts do not happen mid-sentence or mid-note
  • 明确具体：尽可能提供精确的时间戳（MM:SS或HH:MM:SS）
  • 描述内容：如果不知道时间戳，描述你想要的部分（如“他们握手的片段”）
  • 预留缓冲：在裁剪点周围预留少量缓冲时间，避免过渡突兀
  • 检查音频：确保裁剪不会发生在句子中间或音符中途
