Neither Adobe Premiere Pro nor After Effects supports directly importing Sony A7 III AVCHD files for further editing. Fortunately, there is an easy way to fix this issue. Here is how.
“Hi all! I’m new and I am looking for help with converting Sony A7 III AVCHD content for editing in After Effects? What do you use that works?!”
“i need to be able to edit clips from Sony A7 III in Premiere. so i need to convert the movie into a file format that Premiere understands. what software is best for converting the movie?”
Why should this happen? Let me explain it. Firstly you get to learn a bit about the MTS format. *.mts is a filename extension used for AVCHD, a high-definition recording format designed by Sony and Panasonic that uses H.264 (conforming to H.264 while adding additional application-specific features and constraints) codec. H.264 encoded MTS video is highly compressed, good for transporting, but poor for editing.
To get the work done, UFUSoft MTS/M2TS Converter for Mac is a nice application for you. The program converts MTS footage to editable formats (*.avi, *.mpg, *.f4v, *.mov, *.mp4, *.wmv, etc) and obtain HD quality (1920*1080, 1440*1080, 1280*720). Converted file can be easily imported to Adobe Premiere/After Effects for editing. Besides , this Mac MTS to MPEG-2 Converter also generates best editing format/codec for filmmakers and video enthusiasts to use in different NLE apps, such as Avid Media Composer, iMovie, Final Cut Express, Final Cut Pro and more.
