Editing QuickTime (section)

==== Container benefits ====
Because both MOV and MP4 containers can use the same MPEG-4 codecs, they are mostly interchangeable in a QuickTime-only environment. MP4, being an international standard, has more support. This is especially true on hardware devices, such as the [[Sony PSP]] and various DVD players, on the software side, most [[DirectShow]] / [[Video for Windows]] codec packs<ref>{{cite web|url=http://hellninjacommando.com/defilerpak/ |title=DefilerPak - A lightweight codec pack for Windows PCs |access-date=August 15, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150815154602/http://hellninjacommando.com/defilerpak/ |archive-date=August 15, 2015 }}</ref><ref>{{cite web|url=http://www.k-litecodecpack.com|archive-url=https://archive.today/20031031022301/http://www.k-litecodecpack.com/|url-status=dead|archive-date=October 31, 2003|title=www.k-litecodecpack.com|access-date=August 15, 2015}}</ref> include a MP4 parser, but not one for MOV.

In QuickTime Pro's MPEG-4 Export dialog, an option called "Passthrough" allows a clean export to MP4 without affecting the audio or video streams. QuickTime 7 now supports [[surround sound|multichannel]] AAC-LC and HE-AAC audio (used, for example, in the high-definition trailers on Apple's site),<ref>{{cite web|url=http://apple.com/trailers|title=iTunes Movie Trailers|access-date=August 15, 2015|url-status=dead|archive-url=https://web.archive.org/web/20100213200700/http://www.apple.com//trailers//|archive-date=February 13, 2010|df=mdy-all}}</ref> for both .MOV and .MP4 containers.
