Panasonic DMC-GH4, a new Lumix camera, as its predecessor records videos in AVCHD format. What’s more this 16-megapixel compact system camera stands at the top of the Panasonic range and its big selling feature is the 4K ultra-high-definition video recording in .mp4, .mov format. According to my testing, the 4K video was restricted to shooting and editing in Avid Media Composer, which handles 4K input and renders the output to 1080 HD. If you want to import Panasonic GH4 4K video to Avid, you will need to do some preparation before editing.
The reason that you can’t successfully ingest those Panasonic DMC-GH4 recorded 4K files to Avid Media Composer, iMovie, Final Cut Express, Final Cut Pro, etc non-linear editing systems is simple. Currently the 4K footage is not widely supported yet, only a few video editing program can support it. In order to edit Panasonic DMC-GH4 4K MOV/MP4 video files in Avid smoothly, the easy workaround is to use 3rd-party to rewrap and convert Panasonic GH4 4K footage to a more “editable” format in 1080p.
