ffmpeg -i input.mkv -vf "scale=-1:720" -c:v libx264 -crf 18 -c:a aac output.mp4
If you want to change the resolution to, for example, 720p: brassic s05e05 ffmpeg
If you have a video file (let's say in .mkv format) and want to convert it to .mp4: ffmpeg -i input
ffmpeg -i brassic.s05e05.mkv -vn -acodec mp3 brassic_s05e05_audio.mp3 brassic s05e05 ffmpeg
Make sure to replace input.mkv and output.mp4 with your actual file names. These commands are just examples; you may need to adjust the codecs, bitrate, and other parameters based on your specific requirements.
