Question:

Could you guide me through the process of batch resizing videos using FFmpeg commands?

Answer:

Ensure that FFmpeg is installed on your system. It’s available for Windows, macOS, and Linux.

Step 2: Open Your Terminal or Command Prompt

Navigate to the folder containing your video files using the `cd` command.

Step 3: Execute the FFmpeg Batch Resize Command

Use the following FFmpeg command to resize all MP4 videos in the current directory to a width of 1280 pixels and a height that maintains the aspect ratio:

“`bash

for i in *.mp4; do ffmpeg -i “$i” -vf “scale=1280:-1” “resized_$i”; done

“`

This command loops through each MP4 file in the directory, resizes it, and saves it with a new name prefixed by ‘resized_’.

Step 4: Verify Your Output

Check the output files to ensure they’ve been resized correctly.

Additional Tips:

• To resize to a specific height while maintaining aspect ratio, replace `scale=1280:-1` with `scale=-1:720`, where 720 is your desired height.
• For more advanced options, you can use FFmpeg filters to crop, pad, or change the aspect ratio as needed.

Remember,

FFmpeg is a powerful tool with many options and capabilities. The above command is a basic example, and you can customize it further to suit your specific needs. Happy resizing!
