Common topics
Getting started
Download FFmix, let the engine install once on first launch (~25 MB), then drag a file in and pick a task. See the step-by-step guides.
Privacy & your files
Every task runs on your Mac; media is never uploaded. Full details on the privacy page.
FFmix Pro & billing
Free trial, what's included, and how to manage or cancel — see Subscription & billing below.
Subscription & billing
- What's included: FFmix Pro adds 3× parallel queue, unlimited AI parsing, watch-folder automation, and unlimited Finder right-click presets. It's an auto-renewable subscription with a 7-day free trial and Family Sharing — pricing is shown in the App Store and varies by region. Local tasks are already unlimited on the free tier.
- Manage or cancel: open System Settings → [your name] → Media & Purchases → Subscriptions (or the App Store app → your account → Subscriptions), select FFmix, then change or cancel. Cancelling keeps Pro active until the end of the current period.
- Free trial: the 7-day trial converts to a paid annual subscription unless you cancel at least 24 hours before it ends.
- Restore purchases: in FFmix, open Settings → Account → Restore purchases — useful on a new Mac or after reinstalling.
- Refunds: purchases are processed by Apple. Request a refund at reportaproblem.apple.com.
Troubleshooting
- The engine didn't install: reopen FFmix and it retries the one-time download; make sure you have a network connection on first launch.
- A task failed: open the failed job to see the log — it's usually an unsupported source codec. Try running Convert → MP4 on the file first, then your task.
- Subtitle transcription: the first run downloads the Whisper model (~480 MB) once; after that, transcription runs fully on-device and your audio is never uploaded.
- Output folder permission: macOS asks once to allow writing next to your originals — grant it and the prompt won't return for that folder.
System requirements
macOS 14 or later · Apple Silicon · ~18 MB app + ~25 MB engine (installed once on first launch). Everything runs on-device; only the AI input box sends the sentence you type.
