Quick Start Guide

1

Drag and Drop Media Files

Simply drag and drop your media files into Simple Media Encoder to begin the conversion process. The app supports a wide range of audio and video formats.

Tip: You can select multiple files at once for batch conversion.
2

Select Your Output Format

Choose container, codec, and quality. Video: MP4 or MOV (H.264, H.265, ProRes). Audio: WAV, AIFF, CAF, or M4A. Frame rates include 23.976, 29.97, 59.94, and 60.

Tip: Presets fill every control. You can still change settings after picking one. Save your own from Preset Manager (⌘⇧P).
3

Configure Smart Options

Customize how your files are organized and named using the smart options panel:

  • Include settings in filename: Adds conversion settings to output filenames (e.g., "video_H264_1080p_30fps.mp4")
  • Create subfolder: Organizes files by format (Video/MP4, Audio/WAV)
  • Use source file directory: Saves converted files next to originals
  • Overwrite existing files: Replace files with the same name
Tip: Smart filenaming helps you identify conversion settings at a glance, while subfolders keep your workspace organized.
4

Click Convert

Click the "Convert" button to start processing. The app will show real-time progress and estimated completion time.

Tip: You can continue using your Mac while conversion is in progress.
5

Monitor Progress

Watch the conversion progress in real-time. The app displays current status, processing speed, and estimated time remaining.

Tip: The progress bar shows both overall completion and current file progress.
6

Find Your Converted Files

Once conversion is complete, converted files are in the output directory you chose — next to each source file if that option is on, otherwise the folder shown in Options.

Tip: Options on the main window control the folder for this job. Settings (⌘,) stores the default folder for new sessions.

System Requirements

Operating system

macOS 14 Sonoma or later. The binary’s minimum is 14.0. Ventura (13) is not supported.

Processor

Universal — Apple Silicon and Intel. The download is a fat binary (arm64 + x86_64).

Memory

4 GB minimum, 8 GB recommended for large video batches. The converter streams; it does not load entire files into RAM.

Storage

The app itself is a few megabytes. You need free space for the converted files (ProRes and PCM are large).

First Time Setup

1. Launch the App

Double-click Simple Media Encoder in your Applications folder or use Spotlight (⌘+Space) to find it.

2. Files and Folders

The app is not sandboxed. macOS may still ask once for Desktop, Documents, or Downloads. Grant access if you write there.

3. Output folder

On the main window, pick a folder or turn on “Use source file directory.” Settings (⌘,) sets the default for new sessions.

4. Pick a preset

On the main window, choose a preset or set format, codec, and quality yourself. There is no separate “default preset” in Settings.
