> do this on command line: ffmpeg cat\ meets\ skunk.mp4 normalize audio without reencoding video to video2.mp4
To normalize the audio without re-encoding the video, we'll use ffmpeg's loudnorm filter and stream copy for video. Here's the command:
ffmpeg -i "cat meets skunk.mp4" -c:v copy -af loudnorm -c:a aac video2.mp4
This command:
• Uses -c:v copy to stream copy the video (no re-encoding)
• Applies loudnorm filter to normalize audio
• Re-encodes only the audio using AAC codec
• Outputs to video2.mp4
