原文件MKV為H264 720p+AAC 5.1+ASS x2(簡/繁中),容量282MB,
因為字幕難免有錯字,所以我自己用MKVextractGUI_154解出RAW,
修正完字幕後,將AVI+AAC+ASS x1(繁中)用MKVToolnix 2.0.0合併,
雖說合併過程有出現警告信息,不過合出來的MKV好像沒什麼問題,
但容量卻變小了,變成270MB,看了一下AVI檔和AAC檔的總容量也是270MB,
那到底是原MKV文件莫名的變大了,還是輸出的AVI和AAC本身就有問題呢?
這是自行合併AVI+AAC+ASS時出現的信息:
Warning: AAC files may contain HE-AAC / AAC+ / SBR AAC audio. This can NOT be detected automatically. Therefore you have to specifiy '--aac-is-sbr 0' manually for this input file if the file actually contains SBR AAC. The file will be muxed in the WRONG way otherwise. Also read mkvmerge's documentation.
