How to transcode a video using FFmpeg CLI

· 8 min read

Setting up

First make sure you have FFmpeg installed. Follow this guide if you haven't already:

https://docs.tdarr.io/blog/how-to-install-ffmpeg

Running the CLI

A typical FFmpeg command looks like the following:

ffmpeg -i "C:\Transcode\input.mkv" -map 0 -c copy -c:v libx265 "C:\Transcode\output.mkv"

So in this example, all the input streams will be maped over to the output file, and the video stream will be encoded into hevc (h265). The other streams will be left as is. Note how no flag is needed for the output file.

The following provides further encoders available to use, although this depends on what type of build of FFmpeg you're using (different builds come with different encoders):
