How to Use FFmpeg for Professional Video Format Conversion

FFmpeg is a comprehensive command-line utility that excels in converting video formats efficiently. It simplifies the process of transforming videos from one format to another, such as converting MOV to MP4 or MP4 to GIF. This guide will walk you through the essentials of video conversion using FFmpeg.

Ensure FFmpeg is installed on your system before proceeding. If it's not, follow the installation guide for FFmpeg on Windows or Mac in our related article.

Steps for Video Conversion with FFmpeg:

First, verify FFmpeg installation with the following terminal command:

ffmpeg -version

Converting MOV to MP4

Use this command to convert a MOV file to MP4 format:

ffmpeg -i -q:v 0 output.mp4
  • i Specifies the input file, named
  • q:v 0: Sets the video quality, with q:v controlling the quality level. The value 0 represents the highest quality, with the range extending to 51 for the lowest quality.

Converting WEBM to MP4 video

To convert a WEBM file to MP4, apply this command:

ffmpeg -i input.webm -c:v libx264 -c:a aac -strict experimental output.mp4
  • i input.webm: Identifies the input file input.webm.
  • c:v libx264: Utilizes the libx264 codec for video encoding, known for its efficiency.
  • c:a aac: Chooses AAC as the audio codec.
  • strict experimental: Enables experimental codecs, if needed.
  • output.mp4: Names the resulting MP4 file.

Converting MP4 to GIF

For converting MP4 to GIF, the following command is used:

ffmpeg -i input.mp4 -vf "fps=10,scale=1080:1920:flags=lanczos" -c:v gif output.gif
  • i input.mp4: Specifies the input.mp4 file.
  • vf "fps=10,scale=1080:1920:flags=lanczos": Applies video filters, setting frames per second to 10, scaling to 1080x1920, and using the Lanczos rescaling algorithm.
  • c:v gif: Sets the video codec to GIF.
  • output.gif: Determines the name of the output GIF file.

Convert MOV to FLV

To convert MOV to FLV, utilize this command:

ffmpeg -i -c:v flv -c:a mp3 -b:v 1000k -b:a 192k output.flv
  • i Indicates the file.
  • c:v flv: Specifies the FLV video codec.
  • c:a mp3: Sets MP3 as the audio codec.
  • b:v 1000k: Establishes a video bitrate of 1000kbps.
  • b:a 192k: Sets an audio bitrate of 192kbps.
  • output.flv: Names the output FLV file.

Through these steps, FFmpeg empowers you to adeptly convert video formats. Explore various options within FFmpeg to further refine your video conversion tasks.
