FFmpeg Commands

 remove audio from video using ffmpeg

To remove the audio from a video using ffmpeg, you can use the following command:

sh
ffmpeg -i input_video.mp4 -an -vcodec copy output_video.mp4

Here's a breakdown of the command:

• ffmpeg: The command to run ffmpeg.
• -i input_video.mp4: Specifies the input video file.
• -an: Removes the audio stream.
• -vcodec copy: Copies the video stream without re-encoding.
• output_video.mp4: Specifies the output video file.

Replace input_video.mp4 with the path to your input video file, and output_video.mp4 with the desired path for the output file.

I want audio and video individually

To separate the audio and video into individual files using ffmpeg, you can use the following commands:

1. Extract the video without audio:

sh
ffmpeg -i input_video.mp4 -an -vcodec copy output_video.mp4

2. Extract the audio:

sh
ffmpeg -i input_video.mp4 -vn -acodec copy output_audio.aac

Here's a breakdown of the commands:

• Extracting the video without audio:

  • ffmpeg: The command to run ffmpeg.
  • -i input_video.mp4: Specifies the input video file.
  • -an: Removes the audio stream.
  • -vcodec copy: Copies the video stream without re-encoding.
  • output_video.mp4: Specifies the output video file without audio.

• Extracting the audio:

  • ffmpeg: The command to run ffmpeg.
  • -i input_video.mp4: Specifies the input video file.
  • -vn: Removes the video stream.
  • -acodec copy: Copies the audio stream without re-encoding.
  • output_audio.aac: Specifies the output audio file. (You can change the extension to .mp3, .wav, etc., depending on your desired audio format.)

Replace input_video.mp4 with the path to your input video file, output_video.mp4 with the desired path for the output video file, and output_audio.aac with the desired path for the output audio file.

I want to overlap video with text

To overlay text on a video using ffmpeg, you can use the drawtext filter. Here’s a basic example of how to do this:

sh
ffmpeg -i input_video.mp4 -vf "drawtext=text='Your Text Here':fontcolor=white:fontsize=24:x=10:y=10" -codec:a copy output_video.mp4

Here's a breakdown of the command:

• ffmpeg: The command to run ffmpeg.
• -i input_video.mp4: Specifies the input video file.
• -vf "drawtext=...": The video filter to overlay text.
  • text='Your Text Here': The text to overlay on the video.
  • fontcolor=white: The color of the text.
  • fontsize=24: The size of the text.
  • x=10:y=10: The position of the text (in pixels) from the top-left corner.
• -codec:a copy: Copies the audio stream without re-encoding.
• output_video.mp4: Specifies the output video file.

You can customize the drawtext filter with additional options:

• Positioning: You can use expressions like x=(w-text_w)/2 to center the text horizontally and y=(h-text_h)/2 to center it vertically.
• Font: You can specify a custom font with fontfile=/path/to/font.ttf.
• Shadow: You can add a shadow with options like shadowcolor and shadowx/shadowy.

Example with Custom Font, Centered Text, and Shadow

sh
ffmpeg -i input_video.mp4 -vf "drawtext=text='Your Text Here':fontfile=/path/to/font.ttf:fontcolor=white:fontsize=24:x=(w-text_w)/2:y=(h-text_h)/2:shadowcolor=black:shadowx=2:shadowy=2" -codec:a copy output_video.mp4

In this example, replace /path/to/font.ttf with the path to your desired font file.

Feel free to adjust the parameters as needed for your specific requirements.
