MPG stores multiple audio streams as first-class tracks, but MP4 playback support past the first track is inconsistent, so most players will only ever expose one. Choose the track you really want before converting; the others are better extracted to their own files than left in a container that hides them. MPG shi ne fassara na DVD mai rubuta kayan aikin, da kamfen ɗin da aka fi sani da kuma kayan aikin shiga watsawa suna ganewa, don haka yana da amfani ga waɗannan maɓuɓɓugar ruwa.

Interlacing and aspect ratio, in that order. Material made for television is interlaced almost without exception, so deinterlacing must be on or every moving edge arrives combed; and a large part of it is stored as non-square pixels with a flag saying how wide to display it, which a converter that ignores the flag turns into a stretched or squashed MP4. Check the first few seconds of the output before running a batch — both faults are apparent immediately and invisible in the settings. MPG shi ne irin shirin MPEG na ruwa kamar yadda.mpeg — wannan fassara ta uku-alƙawari ne DOS-era truncation, ba wani daban format.
