The QT format (QuickTime) is a container format developed by Apple for video and audio files. Although it is technically closely related to the now dominant MP4 format, QT is hardly supported outside the Apple world. Converting to MP4 is a good way to maintain quality while increasing compatibility.

QuickTime: Pioneer in digital video history

When Apple introduced QuickTime in 1991, it was something of a revolution: ordinary computers could play videos. At that time, they were still very small and had a low resolution with few frames per second. At a time when multimedia on PCs was still a dream of the future, Apple set a milestone.
In the years that followed, however, QuickTime became the de facto standard for digital videos on the Mac. QuickTime was also present on Windows for a long time: Apple bundled the QuickTime player with iTunes. Many websites also relied on QuickTime videos in the early 2000s. Even Apple's film trailers were available exclusively in QuickTime format for years.

From QuickTime to MP4

The MP4 format is based directly on Apple's QuickTime container. When the MPEG group was looking for a standard for MPEG-4 video in the early 2000s, it adopted the container structure of QuickTime and developed the MP4 format (MPEG-4 Part 14) from it. Technically, QT and MOV are therefore closely related to MP4. The differences lie mainly in the supported codecs and metadata.
Despite this relationship, MP4 has long since supplanted its ancestors. The decisive turning point came in 2016 when Apple discontinued the QuickTime Player for Windows. Since then, there has been no official way for Windows users to play QT files natively; only alternatives such as VLC are still compatible.

Why convert QT to MP4?

Today, QT files mostly originate from older archives such as video productions and home recordings. Most of these were created on Macs, sometimes using professional software, when QuickTime was still the standard for export formats. Since MP4 can be played on virtually any device, browser and operating system, conversion is an easy way to achieve universal compatibility. Since both formats have the same technical origin, recoding is usually not even necessary, so there is no loss of quality.
