  3. Run the Compression Command: Here’s where the fun begins. Use this simple spell: ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4. Replace input.mp4 with your video’s name and output.mp4 with what you want the compressed file to be called. ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4 Here’s a breakdown of what each part of the command means:
  • ffmpeg: This is the command to invoke FFmpeg.
  • -i input.mp4: This specifies the input file, in this case, input.mp4.
  • -vcodec h264: This part of the command sets the video codec for the output file. h264 is a popular video compression standard, known for its high compression efficiency and good video quality.
  • -acodec mp2: This specifies the audio codec for the output file. mp2 stands for MPEG-1 Audio Layer II, which is a standard for the compression of audio signals. It’s an older audio format that predates more modern codecs like AAC and MP3 but is still used in some contexts for its compatibility and decent sound quality.
  • output.mp4: This is the name of the output file, which in this case will be encoded with the H.264 video codec and MP2 audio codec. How To Compress a Video with FFMPEG: Step 3 How To Compress a Video with FFMPEG: Step 3

How To Customize Compression Using Bitrate

Tweak the video quality and size by adjusting the bitrate, a real monkey’s wrench in your toolbox!

  1. Choose a Bitrate: Use the -b:v option to set a video bitrate (like 500k for 500 kbps). Lower bitrates mean smaller files but lower quality. It’s all about finding the right balance between size and quality. ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 -b:v 500k output.mp4 How To Customize Compression Using Bitrate: Step 1 How To Customize Compression Using Bitrate: Step 1 How To Customize Compression Using Bitrate: Step 1 How To Customize Compression Using Bitrate: Step 1

How To Customize Compression by Adjusting Resolution

Sometimes you need to trim the tree to fit your jungle. Let’s adjust the video resolution!

  1. Scale the Resolution: Use -vf “scale=1280:720” to change the resolution. This is like finding the right branch to swing from – not too high, not too low! ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 -vf "scale=1280:720 output.mp4 How To Customize Compression by Adjusting Resolution: Step 1 How To Customize Compression by Adjusting Resolution: Step 1 How To Customize Compression by Adjusting Resolution: Step 1 How To Customize Compression by Adjusting Resolution: Step 1

How To Customize Compression by Modifying Audio Bitrate

Let’s not forget the rhythm of the jungle – the audio! Fine-tune it to your liking.

  1. Adjust the Audio Bitrate: With -b:a, you can set the audio bitrate. This is like tuning your jungle drums to the perfect beat! ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 -b:a 500k output.mp4 How To Customize Compression by Modifying Audio Bitrate: Step 1 How To Customize Compression by Modifying Audio Bitrate: Step 1 How To Customize Compression by Modifying Audio Bitrate: Step 1 How To Customize Compression by Modifying Audio Bitrate: Step 1
