Plays MKV and WebM.
Leah plays MP4, MOV and M4V files, and every other video your Mac can play. It also plays MKV and WebM files with H.264, HEVC (H.265), MPEG-2, MPEG-1, VP9 or AV1 video. VP9 plays on Macs with Apple silicon, and AV1 on Macs with Apple M3 or later.
Subtitles that show up on their own.
Leah shows SRT, ASS/SSA, WebVTT, PGS and VobSub subtitles. A subtitle file next to the video with the same name, such as Movie.srt, shows up on its own. Drag any other SRT, WebVTT, ASS or SSA file onto the video to add it. Leah picks subtitles in your Mac's preferred language.

Lossless surround sound in up to 7.1 channels plays exactly as it was recorded. Leah also plays 5.1 surround sound, and AAC, Apple Lossless, FLAC, Opus, PCM, MP3 and MP2 audio.
Smooth interlaced video.
Interlaced video from DVDs, TV recordings and camcorders is deinterlaced as it plays, so motion stays smooth.
