根据小日本2.54的帮助文件,参数应该被设置成符合VCD标准后才能复合:
Selection | Output | MPEG-1 System (automatic) | Output a standard MPEG-1 stream. Normally, this output has a constant bitrate. | MPEG-1 System (VBR) | Output a standard variable bitrate MPEG-1 stream. | MPEG-1 Video-CD | Output a standard MPEG-1 stream suitable for VCDs. The parameters should be set to the VCD standards. | MPEG-1 Video-CD (non-standard) | Output a non-standard MPEG-1 stream suitable for VCDs. | MPEG-2 Program (VBR) | Output a standard MPEG-2 stream. | MPEG-2 SuperVideoCD (VBR) | Output a SuperVCD stream. The parameters should be set to the SuperVCD standards. |
总之,MPEG工具只有分离与复合的功能,没有转码功能。
在流格式为 MPEG-1 Video-CD 时仍然接受MP3音频可能是一个BUG。不过在导入后程序有自动判断格式功能,倒不是可以轻易改成VCD的(见下面的帮助文件):
Normally, one will want [MPEG-1 System (Auto)], which is the default, or [MPEG-2 (VBR)] for the stream type; however, TMPGEnc will automatically select the most appropriate output stream type after the video source is selected as well. |
