They provide a link to a static binary (I chose the 64bit variety) and installing it is as simple as dragging it into the app. The app is 8 euros and requires that you manually install the FFmpeg binary. The author plans to add a total batch indicator as well. My favorite feature (other than the quick and high quality conversion) is the very clear indicator in the dock icon that shows how much remuxing (or encoding) is left on the current file. Just drag the video file into the app, choose a codec, and press start. Since my iPad and iPhone can’t play 5 channel audio, there is no point for me to leave it. The final file has the exact same video with no changes, but audio re-encoded to AAC stereo. My original files start off as 720p video encoded via h264, the audio is usually AC3 or DTS. With this app (which I believe is new to the scene,) I can just select the “video stream passthrough” option, AAC conversion option and boom, my MKV’s are magically (and quickly) turned into MP4 files compatible with Apple devices. Previous attempts at mastering the command-line or other GUI hacks, left me files that aren’t compatible with Apple devices. IFFmpeg is the first GUI That makes it possible for me to easily remux my MKV files into MP4.

I’ve tried a bunch of different tools for doing this, even came up with a bash script (hosted on my github account,) and now I’m using iFFmpeg, a new GUI for FFmpeg. Since Apple doesn’t natively support MKV, I’m forced to remux into MP4.

I’m big into movies and I like the MKV format for storage, but iOS devices for watching.
