Like most major NLEs, Apple iMovie doesn’t have native support for H.265/HEVC video files. To be able to ingest H.265/HEVC video to iMovie for further editing, you will need to transcode H.265/HEVC video to a Mac friendly format first, such as Apple’s InterMediate Codec encoded MOV format, which iMovie will recognize and handle well.
How can I work with HEVC 4K video in iMovie?
“Hi, there, when is Apple going to implement full support for HEVC/H.265 into iMovie? I’m shooting with a new Samsung NX1 4K camera which records video files using HEVC (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 HEVC 4K video? Does anyone know a solution? Please advice. 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. The content below will guide you through the process of converting H.265/HEVC files to AIC .MOV for iMovie editing with optimum performance using this Mac converter app.
