Top 5 Best MKV to iMovie Converters for Mac/PC (Free Included)

iMovie, bundled with your Mac, is a free and popular video editing program- a part of the iLife suite of the digital lifestyle. It lets you import video sources from downloaded DV-encoded files, RAW camera, Panasonic P2, Sony XDCAM HD, and more. iMovie supports a quite limited number of media formats, and MKV (Matroska Video) is one of the unsupported formats. If you want to import MKV to iMovie, you have to convert MKV to a video format supported by iMovie. This post will walk you through the best MKV to iMovie converter for Mac and PC.

iMovie Compatible Formats

• Video formats for iMovie: MP4, MOV, M4V, 3GP, DV, etc.
• Audio formats for iMovie: MP3, AAC, AIFF, WAV, etc.
• iMovie supported export formats: MP4, MOV, AAC, MP3, AIFF, WAV
• iMovie unsupported formats: MKV, WMV, VOB, WMA, FLV, NSV, APE, WebM, etc.

Why iMovie fails to import some MP4 files?

Generally, iMovie supports MP4 files encoded with MPEG4/AAC or H.264/AAC data. If the imported MP4 files use other codecs, iMovie may not accept them. Another reason is that your MP4 video contains codecs for audio and subtitle streams which are not supported by iMovie.

Just like some mobile phones can’t play MP4 video files encoded with Xvid because they only support DIVX and H264 codecs.

Can iMovie edit AVI files?

Most of the time it's not, but there are two cases where it's allowed.

1) The AVI video you are going to import contains MJPEG data.

2) The imported AVI file is using the same codec as iMovie.

Can iMovie edit MKV files?

Obviously not! iMovie doesn't empower you to drag MKV videos into the software. So, as aforementioned, you should convert MKV to iMovie supported formats like MP4 and MOV.
