                Resize/Scale/Change video resolution using ffmpeg
              
          
    Check original video resolution

ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=s=x:p=0 filename-here.mp4

you will see file resolution like 1280x720
then resize to expected resolution:

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months)
https://m.do.co/c/5424d440c63a
2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

  
## generate_ssh_key
ssh-keygen -t rsa -b 4096 -C "achmadfatoni(replace with name)"
