FFmpeg
Inspect, remux and convert local audio/video streams with explicit command-line control.
Tags: video, audio, subtitles, command-line
For: Video creators, podcast editors and developers comfortable with a terminal.
When to consider it
You have a local recording or caption file and need a repeatable conversion rather than a visual editing timeline. FFmpeg exposes stream mapping and processing through commands; ffprobe provides media inspection. Our local multitrack test preserved both audio streams with explicit mapping, while automatic selection kept only one.
Practical limits
There is no native waveform editing or track-solo workflow in this command-line profile. A successful command does not prove correct stream selection, valid caption timing or compatibility with your target editor. Available codecs depend on the build, and filtering requires a processing path rather than stream copying.
We tested the Ubuntu distribution build 6.1.1-3ubuntu5, not the latest release. The synthetic recording was four seconds long. We did not benchmark large files or test Windows, macOS, browser playback or NLE imports. Local file commands were used; no network capture was performed, and FFmpeg can also process network inputs.
Our tested coverage
- Review: the multitrack handoff a successful remux can get wrong — stream mapping, copied stream hashes and failure cases.
- Guide: fix reversed SRT timestamps before WebVTT conversion — local timing gate and a reproducible malformed-cue test.
Installation and licensing
Use the project’s official download page to find source or platform-specific build providers. Record your installed version when comparing results. FFmpeg’s licensing depends on enabled components; consult the project’s licensing notes before redistributing a build. This profile does not audit licensing compliance.
