I am trying to import .mp4 files into iTunes version 11. The ones that I have downloaded works fine, but when I converted .avi files to .mp4 and tried to open them in QuickTime to check them, I get an error: QuickTime Error 2041- An Invalid Sample Description Was Found in the Movie. These files won’t show up in iTunes, the progress bar shows them loading but after that nothing appears anywhere. The .mp4 files work in the VLC player but not in QuickTime.

Many QuickTime (QT) users are facing a similar issue as mentioned above. QT is an extensible multimedia framework developed by Apple Inc. It can handle several formats of digital video, pictures, panoramic images, sound, etc. It was first made available in the year 1991. Apple stopped the support for the Windows version of QT in 2016. Despite being popular among users, sometimes MP4 files can become inaccessible in QuickTime due to various errors like Error 2041.
