whyWhy does it seem to be so difficult to simply change a video's container?

forFor example, when iI download ".avi" & ".mkv" video's from the internet & want to watch them on my Apple devices (iPhone, iPad, Apple TV), iI need them to be ".mp4" instead.

iI don't want to spend the TIMEtime to go thruthrough the whole "conversion/transcoding" process with apps like Handbrake when it seems you can simply change their containers out with apps like Mkv2Mp4 or the old Video Container Switcher apps in a fraction of the time.

problemProblem is, when iI use those container changing utilities, various problems arise, like...

  • having mp4's with audio out of sync, or
  • having mp4's with no audio at all, or
  • having mp4's with very jittery video.

iI love the speed of these container changing apps but why don't the video's play exactly the same since they're not actually converting the codecs & such?
