No. Examining and checking files is free, and so is fixing your first three files. One in-app purchase unlocks the rest, with Family Sharing, and you can restore it on any Mac.

Yes. Your first three files can be fixed free, one at a time from each file’s page, so you can check the results on your own setup. A file counts once, however many fixes it needs, and only when its new file is saved: a fix that fails or that you cancel doesn’t use one up. Fix All, fixing in watched folders and Fix File in Shortcuts need the purchase.

No. Every fix writes a new file, checked before it is kept. There is an optional setting, off by default, to move an original to the Trash after a verified fix. Nothing is ever permanently deleted.

Never. The picture is copied exactly. Only new tracks are made: a Dolby Digital Plus track encoded from your lossless audio, or text subtitles read from picture subtitles. The original tracks stay.

Remux Doctor makes no claims about how any device or player will handle a file. A target is your own choice of what you want your files to look like, and each check states facts about the file and that choice.

Dolby Vision profile 7 files carry an extra layer. A minimal layer (MEL) holds no extra picture detail. A full layer (FEL) can. Converting to profile 8.1 removes the layer, so Remux Doctor samples it first and leaves full layers for you to decide on one by one. You can also save the layer and restore profile 7 later.

MKV, MP4, M4V, MOV, TS and M2TS.

Yes. The Shortcuts app has Check File, Check File Against Target, Add to Library, Fix File and Library Status. To use one from Finder, make a shortcut that receives files from Quick Actions and turn on Use as Quick Action; it then appears when you Control-click a video, under Quick Actions. Remux Doctor also adds Check with Remux Doctor to the Services menu, which opens the file in the app. Fix File needs the in-app purchase.

No. Remux Doctor needs a Mac with Apple silicon and macOS 15 or later.
