    FFmpeg (or "Fast Forward MPEG") is a simple yet feature rich command line utility to allow the manipulation (including decoding, encoding, transcoding, muxing, demuxing, streaming, filtering, and playing) of media and video files. This utility differs from other GUI orientated software as it employs the WYSIWYG methodology (What You See Is What You...

    Ffmpeg is available in pretty much all and any Linux distribution, and there are also builds for Windows and Mac. If you want to know what it can do, you can check its capabilities by running ffmpeg without arguments or with an optional -hide_banner flag. You can also use the help option for the main program as well as any of its many sub-commands....

    One of the most common tasks is converting files from one format to another. Remember my example of how to extract audio files from an FLV clip? Same thing. But you may want to convert a video recorded on a camera to something like MP4, or maybe convert your OGG files to MP3, or similar. There's an endless variety of scenarios, and an equally endle...

    Another common task is changing the size of the video (resolution) and the quality of streams. Ffmpeg lets you do this in different ways. You can force ratio (and break the default aspect ratio), or preserve it by specifying either the vertical or the horizontal value plus a magic qualifier. You can crop video borders, and you can re-encode streams...

    Ffmpeg can also manipulate pictures, even though it's a media utility. But hey, pictures are media, and essentially, videos are moving pictures, right! Some of the tasks you'd want - extract frames from a video in order to create thumbnails (high-quality ones, too) rather than manually pausing video or creating hectic screenshots. You can also do t...

    This is another useful scenario. If you have a very big clip, but you only need a few minutes or seconds, ffmpeg can cut out the necessary pieces. Likewise, you can combine multiple files into one stream - both video and audio. Ffmpeg lets you choose the desired start and end timestamps, so you have a lot of leeway in how you do handle the task. -t...

    Remember my VLC & subtitlesarticle? Well, if you're not intimidated by the command line, you can do the same thing with ffmpeg. As a trivial example, say you have separate audio and subtitle files. Without any additional processing, you can just use the video filtering option for this: ffmpeg -i input.avi -vf output.avi A mor...

    This is another interesting usecase. Like any human being, you may want to take any video, speed it up 2x and then add Benny Hill music, and there should be much rejoicing. You could also slow down action, and then, to spice things up, also add smoothing so the slowed sequence does not feel stilted. For example, we may have our stop motion video - ...

    I hope you found this fruitful, enjoyable and relevant. Ffmpeg is the workhorse - no, it's a whole cavalry - of audio and video tweaking in Linux, and it has so many practical tools, options and configurations that getting started can be confusing and maybe even intimidating. Those emotions should have evaporated by now as you've read through this ...
