The Osmo system from DJI combines the Zenmuse X3 camera/gimbal with a detachable handle, bringing the benefits of stabilized 4K shooting to a handheld form factor. The camera features a 1/2.3" CMOS sensor that enables up to full DCI 4K (4096 x 2160) video recording at 24 or 25p as well as 12MP photo capability. In terms of video format and media recording, the DJI Osmo shoots both DIC 4K, UHD 4K, Full HD(1080p) and HD(720p) MP4 video with MPEG-4 AVC/H.264 compression on an external microSD/SDHC/SDXC card.
For Mac users, it would be a good idea to turn the video clips into professional edited movies for sharing or burning to DVD with the help of the iMovie or Final Cut Express. The problem is that both iMovie/FCE does not support H.264 video very well, since H.264 is an ideal video compression codec but not a good video editing codec.
To fix this issue, you can transcode DJI Osmo H.264 MP4 to iMovie/FCE most compatible editing format-Apple Intermediate Codec (AIC). To encode Apple Intermediate Codec, you will need a professional video codec producer called Pavtube HD Video Converter for Mac, with which you can directly convert DJI Osmo H.264 MP4 to Apple Intermediate Codec for fast and smooth post-production workflow.
Downscale DJI Osmo 4K video to 1080p
Since both iMovie/FCE do not have the perfect capability to deal with 4K resolution video, in addition, rendering 4K video files require a lot of computer processing power, to have a more smooth workflow, you'd better downscale 4K video to 1080p in the program's "Profile Settings" window.
