## What it is
Shutter Encoder is a free, open-source GUI application for video, audio, and image transcoding built on FFmpeg, aimed at video editors and post-production professionals. It offers batch processing, presets, lossless cutting and remuxing, subtitle handling, loudness normalization, and color/LUT adjustments across Windows, macOS, and Linux.

## Use cases
- compress videos without quality loss
- convert video files to ProRes or DNxHR for editing
- cut and trim videos losslessly without re-encoding
- batch convert a folder of videos to H.264 or H.265
- burn subtitles into a video
- normalize audio loudness in video files
- extract audio tracks or subtitles from a video
- generate images from a video or video from an image sequence

## When to choose
- you need a reliable GUI front-end for FFmpeg with professional codecs like ProRes, DNxHR, and AV1
- you do post-production ingest workflows, e.g. preparing media for Avid Media Composer
- you want lossless cutting, remuxing, or audio replacement without re-encoding
- you need batch processing with reusable presets and watch folders

## When to avoid
- you need a command-line-only or scriptable transcoding pipeline - use FFmpeg directly
- you need non-linear video editing rather than conversion and processing
- you require a code-signed binary, since unsigned builds trigger OS warnings
