# ffmpeg: This is the FFmpeg command, a powerful command-line tool for manipulating and converting audio and video files.
#  -i input.mp4: This part specifies the input file, which is the video you want to convert (input.mp4).
#  -c:v mpeg4: Here, -c:v sets the video codec to be used for the output. In this case, the chosen codec is MPEG-4 (mpeg4).
#  -q:v 5: This sets the video quality. A lower value, like 5, results in higher video quality. The value is a quantization parameter, and lower values indicate higher quality.
#  -tag:v DIVX: This specifies the video tag as DIVX.
#  -s 640x480: Sets the output video resolution to 640x480 pixels.
#  -c:a libmp3lame: This sets the audio codec to be used as LAME MP3 (libmp3lame).
#  -q:a 5: Similar to the video quality, this sets the audio quality. A lower value indicates higher audio quality.
#  -ac 2: Defines the number of audio channels as 2, which represents stereo audio.
#  -ar 44100: Sets the audio sample rate to 44.1 kHz. The sample rate is the number of audio samples per second.
#  output.avi: Specifies the name of the output file, which will be in AVI format (output.avi).

# In summary, this command uses FFmpeg to convert the input video (input.mp4) into a new video in AVI format (output.avi). It uses the MPEG-4 video codec with specified video and audio quality settings, resolution, and other parameters. The result is a video with the desired settings and format.
