## FFmpeg Cheat Sheet

Let's start with some basics:
`-i` is follwed by the path to the source video
`-c:v` sets the video codec you want to use.  
Options include `libx264` for H.264, `libx265` for H.265/HEVC, `libvpx-vp9` for VP9, and `copy` if you want to preserve the codec of the source video
`-b:v`
`-c:a`
`-b:a`

Get video info

```
ffmpeg -i input.mp4
