Converting MKV to MP4 using FFmpeg is a straightforward process that can be achieved with a simple command-line instruction. In this tutorial, we will cover how to convert MKV files to MP4 at 720p resolution using FFmpeg.

Step-by-Step Instructions

1. Open your terminal or command prompt and navigate to the directory where your MKV file is located.

2. Use the following command to convert your MKV file to MP4 at 720p:

ffmpeg -i input.mkv -c:v libx264 -crf 18 -c:a aac -b:a 128k output.mp4

Here's an explanation of each part of the command:

- -i input.mkv specifies the input file, which is your MKV file.

- -c:v libx264 sets the video codec to H.264 (also known as MPEG-4 AVC).

- -crf 18 adjusts the quality of the video by controlling the bitrate and compression ratio.

- -c:a aac sets the audio codec to Advanced Audio Coding (AAC).

- -b:a 128k sets the bitrate for the audio.

- output.mp4 specifies the output file name.

3. Press Enter to execute the command, and FFmpeg will start converting your MKV file to MP4 at 720p resolution.

Tips and Variations

* To adjust the video quality, you can change the value of -crf from 18 to a higher or lower number. A lower value will result in better quality but larger filesizes.

* To reduce the bitrate of the video, you can decrease the value of -b:a from 128k to a lower number.

* You can also add additional options to your command to perform other tasks such as cropping, scaling, or adding subtitles.
