如果 MOV 文件有章节或流流元数据, 我们就会将艺人 / 标题/ 相册字段复制到 AMR 容器中。 否则, AMR 文件将不加标记, 如果您需要更丰富的标签, 请使用标签编辑器 (Mp3tag, Picard) 后导 。
从 MOV 文件提取 AMR 需要多长时间?
+
Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour MOV → AMR finishes in 3-9 minutes on the standard pipeline.
Can I extract just a section of the MOV audio as AMR?
