Linux Keyframe Script Guide

Installing prerequisites

First we will need the following things to install:

ffmpeg
libxvidcore
scxvid

To install ffmpeg all we need to do is open terminal, you can either by ctrl+alt+t or right click on the desktop on pressing open terminal here.

Then we will run the following command in the terminal:


      sudo apt -y install ffmpeg

sudo - allow administrator premission so the ffmpeg could be installed in the system
apt - this is ubuntu default package manager
-y - this a flag that allow to skip the "Do you want to install [y/n]" part when installing
ffmpeg - pretty self explanatory

Now we will install libxvidcore the same way with the command:


      sudo apt -y install libxvidcore-dev

After we installed both of the package we can download and compile scxvid.

We download the code from the following link: scxvid download

In the link we will press the big green button that says "Clone or download" and press "download zip".
Save the zip file in your desired package and then open the file explorer in the folder and chooce extract here. After we extract the zip we will have a folder named: SCXvid-standalone-master
enter the folder than right click and choose open terminal here.
Then we will run the following command in the terminal


      cc -o scxvid scxvid.c -lxvidcore

this will compile the code are output an executable file called scxvid in the same folder.

Prepering the script

Now that we have everything set we can download the Create_Keyframes code.

Download it from the following link: Download Create_Keyframe

Then open the file in you favorite editor and edit the following line:


      SCXvid=/path/to/complied/scxvid

Change to the place you compiled the scxvid, so if you extracted the zip into the Downloads folder your path should look something like this:


      ~/Downloads/SCXvid-standalone-master/scxivd

Save the files and exit,
Change the premissions to the Create_Keyframes file in the terminal by running the following command:


      chmod +777 ./Create_Keyframes.sh

This will make the script executable.

Generating Keyframes

now all we have to do in order to generate keyframes is to put the video we want in the same folder as Create_Keyframes.sh open terminal and running the following command:


      ./Create_Keyframes.sh video_name

And wait for it to finish then we will have glorious keyframes.
