Adobe warned for years
that Quicktime support was going away. Quicktime wss abandoned by Apple (which replaced it with AVFoundation) and pose some serious security threats to its users. In the April 2018 release of Adobe video software, Adobe decided to drop support for the Quicktime exporter
. Animation, ProRes and DNxHD are still available, but codecs that were coded as Quicktime extensions don't work anymore, such as HAP codecs
are new native plugins for the whole Adobe CC Video suite, working on both MacOS and Windows. It brings
fast and efficient codecs to After Effects's render queue and a new Format choice in Premiere Pro and Media Encoder's Export window
. It supports HAP codecs, with Snappy lossless compression and CPU chunks for multi threaded decompression, without any resolution restriction. And it even provides new algorithms for better HAP quality.
MOV is a standard, still written and read by most video software and unaffected by Adobe's and Apple's decisions.
