How to Crop Videos
During a recent episode of the Script and Style podcast, I had noticed that the video recording had showed a bit of our internal chat that wasn't necessary for our viewers to see. While there's nothing wrong with giving viewers a peek into the show preparation, presenting the best possible video is our priority. So how can we crop a video via command line?
The amazing ffmpeg utility allows engineers to crop videos with one easy to use filter:
# Crop an image to 500x500 starting at 0x0
ffmpeg -i sns-episode.webm -filter:v "crop=500:500:0:0" sns-episode-cropped.mp4
The crop filter format is easy to follow: {desired_width}:{desired_height}:{start_x}:{start_y}.
I've written dozens of posts about ffmpeg and how it has the power to manipulate videos in amazing ways. Now you know how to crop videos quickly from command line!

As broadband speed continues to get faster, the web continues to be more media-centric. Sometimes that can be good (Netflix, other streaming services), sometimes that can be bad (wanting to read a news article but it has an accompanying useless video with it). And every social service does...
