Support

System requirements

• macOS 14 Sonoma or later
• Apple Silicon (M1 or later) only. Intel Macs are not supported.

Supported formats

If a video plays in macOS's built-in QuickTime Player, it plays in this app. The App uses macOS's AVFoundation under the hood, so there are no extra codec packs to install.

What plays reliably

.mp4 and .mov files containing H.264 or HEVC video (the formats produced by iPhones, cameras, and most editing apps).

What may not play

VP9 and AV1 codecs (often found in videos downloaded from YouTube and similar sites) are not supported. Note that even files with a .mp4 extension may not play if their internal video codec is VP9 or AV1. Some .mkv and .webm files are unsupported at the container level. Open the file in QuickTime Player first to confirm it plays.

Recognized extensions

mp4, m4v, mov, mpg, mpeg, m2ts, mts, ts, 3gp, 3g2, dv
