How can I work with H.265 4K video in iMovie?
“Hi, there, when is Apple going to implement full support for H.265/HEVC into iMovie? I’m shooting with a new Samsung NX1 4K camera which records video files using H.265 compression with MP4 wrapper. I’m trying to edit the H.265 4K files in iMovie, but can’t get iMovie to ‘read’ them? Is there a workaround to get iMovie to recognize H.265 4K video? Hoping for a solution. Thanks in advance.”

H.265, also known as High Efficiency Video Codec (HEVC), is the successor to the H.264/MPEG-4 AVC compression standard and offers twice the compression while still maintaining the same high quality. It’s a pity Apple hasn’t added full support for H.265/HEVC into iMovie. If you insist on editing H.265/HEVC files in iMovie, you will need to transcode them to an intermediate format that is fully compatible with Apple iMovie before start, such as Apple’s InterMediate Codec (AIC). This requires third party software like H.265/HEVC Converter for Mac.
