FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

• ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

//This is based on a shader from https://alastaira.wordpress.com/2014/12/30/adding-shadows-to-a-unity-vertexfragment-shader-in-7-easy-steps/

Shader "Custom/MobileARShadow"
{
    SubShader {
        Pass {
         
            // 1.) This will be the base forward rendering pass in which ambient, vertex, and
            // main directional light will be applied. Additional lights will need additional passes
            // using the "ForwardAdd" lightmode.

// When creating shaders for Universal Render Pipeline you can you the ShaderGraph which is super AWESOME!
// However, if you want to author shaders in shading language you can use this teamplate as a base.
// Please note, this shader does not necessarily match perfomance of the built-in URP Lit shader.
// This shader works with URP 7.1.x and above
Shader "Universal Render Pipeline/Custom/Physically Based Example"
{
    Properties
    {
        // Specular vs Metallic workflow
        [HideInInspector] _WorkflowMode("WorkflowMode", Float) = 1.0

//Moebius transformations in 3d, by reverse stereographic projection to the 3-sphere,
//rotation in 4d space, and projection back.
//by Daniel Piker 09/08/20
//Feel free to use, adapt and reshare. I'd appreciate a mention if you post something using this.
//You can also now find this transformation as a component in Grasshopper/Rhino
//I first wrote about these transformations here:
//https://spacesymmetrystructure.wordpress.com/2008/12/11/4-dimensional-rotations/

//If you want to transform about a given circle. Points on the circle and its axis stay on those curves.
//You can skip these 2 lines if you want to always use the origin centred unit circle.

OpticalZDefocus

OpticalZDefocus is a physically accurate ZDefocus, which controls circle of confusion size based on lens geometry using the depth of field equation.

1. Set your focal length and film-back characteristics to match the lens that shot your plate
2. Animate your focus distance
3. Adjust the f-stop to match the size of your bokeh to your plate
