How to Convert MKV to MOV

MKV is the go-to container for home media libraries — it supports every codec, multiple subtitle tracks, and chapters. MOV is Apple's container format, required by certain versions of iMovie and Final Cut Pro for direct editing without transcoding. Converting MKV to MOV often just remuxes the container without re-encoding, making it a fast, lossless operation.

Step-by-step instructions

  1. 1

    FFmpeg stream copy (fastest, lossless)

    Remux without re-encoding: `ffmpeg -i input.mkv -c copy output.mov`. This works when the MKV contains H.264/H.265 video and AAC/MP3 audio — codecs the MOV container accepts. It's near-instant (limited by disk I/O, not CPU). If you get an error about incompatible codecs, proceed to the re-encoding step. Verify: `ffprobe output.mov` should show the same codecs as the input.

    FFmpeg with re-encoding for iMovie compatibility

    iMovie works best with H.264 video and AAC audio: `ffmpeg -i input.mkv -c:v libx264 -crf 18 -preset slow -c:a aac -b:a 256k output.mov`. CRF 18 is visually lossless. For Final Cut Pro ProRes output (best editing performance): `ffmpeg -i input.mkv -c:v prores_ks -profile:v 3 -c:a pcm_s16le output.mov` (ProRes 422 HQ, large files but optimized for editing).

  3. 3

    HandBrake (GUI, Windows/Mac/Linux)

    Open HandBrake. Select the MKV source. Change container to MP4 (note: HandBrake labels its output 'MP4' — rename the output to .mov after conversion if required). Set video codec to H.264 and RF to 18 for visually lossless output. In the Subtitles tab, burn in any subtitles from the MKV if needed. HandBrake cannot export true ProRes — use FFmpeg for ProRes output.

  4. 4

    iStatistica / iFlicks on Mac (drag-and-drop)

    iFlicks 3 (Mac App Store) is designed specifically for converting video to Apple-compatible formats. Drag the MKV file into iFlicks, select MOV or M4V output, and it converts using H.264 or H.265 with AAC audio. iFlicks handles metadata and subtitle tracks automatically. For a completely free option on Mac: install FFmpeg via Homebrew (`brew install ffmpeg`) and use the command-line method.

Why convert MKV to MOV?

MKV stores everything, but Apple's edit tools and QuickTime don't open it natively. MOV is the container Apple built its video ecosystem around.

Frequently asked questions

Will MKV subtitles transfer to MOV?
Subtitles in MKV can be stored as SRT, ASS, or PGS (image-based). MOV supports text subtitles natively. With FFmpeg stream copy: `ffmpeg -i input.mkv -c copy -c:s mov_text output.mov` converts text subtitle tracks to MOV format. Image-based PGS subtitles (common in Blu-ray rips) can't be stored in MOV as data — they must be burned into the video: add `-vf subtitles=input.mkv` to the FFmpeg command.
Why won't my MKV open in QuickTime Player?
QuickTime Player on macOS supports MOV and MP4 containers natively, but not MKV. Even if the MKV contains H.264 and AAC (which QuickTime supports), the MKV container itself is the blocker. Installing the Perian plug-in (legacy, macOS 10.6–10.11) or using IINA/VLC bypasses QuickTime. Otherwise, convert to MOV or MP4 using FFmpeg, and QuickTime will open it natively.
Is MOV better than MKV for Mac editing?
MOV is the preferred container for Apple's pro apps — Final Cut Pro reads MOV natively and with ProRes codec achieves the best editing performance. MKV requires a transcoding step in Final Cut Pro (via Compressor or a plug-in) before editing. For simple playback on Mac, MP4 and MOV are equally well supported; MKV requires VLC or IINA. For home media server use, MKV is superior; for Mac editing workflows, MOV is.
