GIF Art Engine For NFT

Introduction

A GIF art engine that will allow you to generate multi-layer GIFs from single GIFs as layers. All the code in this repository has been written by me in c++, inspired by the generative art engine of HashLips that does not support GIFs as layers. The problem arose from my and my teamleader's need to generate animated images and then GIFs, in the same way as HashLips generated static images.

If you found my work useful for any of your projects, please make some donations to support me.

What does the code allow you to do?

When you have downloaded the code you will be able to generate your own GIFs using GIFs as layers. What the code will do is overlay all the GIFs you have chosen in the desired order and generate n final gifs. This is an example of generating a gif with five separate layers:

Num of layer	Layer	Name
1	Background	f8f9f9.gif
2	Character	zombie-male.gif
3	Head	tophat.gif
4	Eyes	bigshades.gif
5	Mouth	lipstick-party_pink.gif

Output:

What functionality does it offer?

Generate GIFs uniquely randomly or by selecting a rarity for each individual layer.
Generation of a preview GIF containing the first n GIFs generated.
Modification of JSON (Metadata) after GIF generation.
After generating a collection you will automatically find in the output folder a file called rarity-list that will tell you the percentage of presence of each layer in the collection.

example: folder that contains the example shown in the introduction.
layers: folder where the subfolders of each animated layer will be placed..
library: folder that contains some libraries written by me. The .hpp files contain the declarations, while the .cpp files contain the definitions. Explanation of the files:
- dnaGenerator: contains all the functions to generate the dna of your NFTs. Either randomly or based on rarity.
- metadataFunction: contains all the functions used to generate the metadata of your NFTs.
- myFFmpegConversion: contains useful functions for overlaying layers and converting videos to gifs and vice versa.
- utils: contains additional features to the standard ones.
output: will contain the result of the program execution and therefore all the generated gifs and JSONs. There will also be the rarity-list file and the preview-gif.gif. file.
src: contains the main files to compile together with the libraries.
tmp: folder where temporary files are stored.

Installation, compilation and execution

Requirements for linux: FFmpeg installed

Requirements for windows: FFmpeg and MinGW installed

On linux if you haven't installed FFmpeg yet, install it with the following command in the terminal:

sudo apt update & sudo apt install ffmpeg -y

On windows to install FFmpeg and MinGW watch these videos:

FFmpeg: https://www.youtube.com/watch?v=r1AtmY-RMyQ
MinGW: https://www.youtube.com/watch?v=guM4XS43m4I&t=305s

The code was tested with FFmpeg version 4.2.4.

If you want to clone the project, run this command:

git clone https://github.com/Goldo02/gif_art_engine_for_nft.git

After doing so, move to the folder where you cloned the project and go to the src folder.

To compile the main.cpp file use the command:

g++ ../library/dnaGenerator.cpp ../library/metadataFunction.cpp ../library/myFFmpegConversion.cpp ../library/utils.cpp main.cpp -o main

To execute:

./main

To compile the update-info.cpp file, use the command:

g++ ../library/utils.cpp ../library/metadataFunction.cpp update_info.cpp -o update_info

To execute:

./update_info

To compile the file preview-gif.cpp use the command:

g++ ../library/myFFmpegConversion.cpp preview_gif.cpp -o preview_gif

To execute:

./preview_gif

Note: remember that every time you modify one of the three files you must also recompile it before running it, otherwise you will run the program out of date with the changes you made.

Usage

To use the algorithm and modify it according to your needs you must open the file main.cpp. Inside it you can distinguish three different sections: layer management, metadata management, rarity management. Description of variables:

Layer Management:
- numbOfPunkToGen: contains the total number of gifs you want to generate
- scale: contains the size in px of the images
- randomized: set to true if you want to generate a collection randomly, regardless of rarity. Set to false generates the collection according to the rarity set later.
- layerDir: vector containing the name of the folders of each layer
- singleLayer: multidimensional vector that contains the name of every single sprite-sheet (in gif format) in every single layer folder. The name of these must match the name of the file in the folders. The use of spaces is not allowed.
Metadata management:
- singleLayerName: name you want to appear in the metadata regarding the specified sprite-sheet..
- name: collection name.
- description: collection description.
- image: links where gifs and JSONs will be hosted.
- extraMetadata: vector that contains some metadata you want to add to each JSON.
Rarity Management:
- rarityList: multidimensional vector of numbers that contains the probability that character has of being selected. The sum of each probability entered for a specific layer must make 100.

This is an example with a collection of mine:

> singleLayer = { {"Celo_Dark.gif", "Celo_Gray.gif", "Faint_Gold.gif"}, {"Ape_Male_Alien.gif", "Blue_Cool_Woman.gif", "Dark_Female_Human.gif", "Dark_Male_Human.gif", "Darker_Male_Human.gif", "Female_Alien.gif", "Female_Ape.gif", "Female_Orc.gif", "Female_Zombie.gif", "Goddess_Night_Woman.gif", "Light_Male_Human.gif", "Lighter_Female_Human.gif", "Lighter_Male_Human.gif", "Male_Alien.gif", "Male_Ape.gif", "Male_Mummy.gif", "Male_Orc.gif", "Male_Robot.gif", "Male_Vampire.gif", "Male_Zombie_Ape.gif", "Male_Zombie.gif", "Red_Burning_Woman.gif"}, {"Bandana.gif", "Beanie.gif", "Blue_Cap.gif", "Cap_Forward.gif", "Cowboy_Hat.gif", "Crazy_Hair.gif", "Fedora.gif", "Green_Cap.gif", "Knitted_Cap.gif", "Male_Wild_Hair.gif", "Top_Hat.gif", "Wallstreetbets_Dark_Crazy_Hair.gif", "Wallstreetbets_Hair.gif"}, {"3D_Glasses.gif", "Big_Shades.gif", "Classic_Shades.gif", "Empty.gif", "Eyepatch.gif", "Male_Earring.gif", "Nerd_Glasses.gif", "Regular_Shades.gif"}, {"Burgundy_Lipstick.gif", "Flashy_Blue_Lipstick.gif", "Gold_Lipstick.gif", "Party_Pink_Lipstick.gif", "Passion_Red_Lipstick.gif", "Purple_Lipstick.gif", "Space_Lipstick.gif", "Pipe.gif"} }; //METADATA MANAGEMENT const vector

Update metadata

Open the update-info.cpp file located in the src folder. Here too you will find a number of variables that you can modify. Modify them according to your needs and then run the code to update the metadata.

Example:

> &extraMetadata = { {"Compiler:", "CeloPunks Algorithm"} };">

const string name = "CeloPunk Animated Edition";
const string description = "CeloPunks Animated Edition is a collection of 1500 unique special animated punks. Not affiliated with LarvaLabs.";
const string image = "";
const int numbOfPunkToGen = 1500;
const int nLayers = 5;
const vector
   
    > &extraMetadata = 
{
{
    "Compiler:", 
    "CeloPunks Algorithm"}
};

Creating a gif preview

Open the preview-gif.cpp file located in the src folder. In this file the only parameter present is numbOfPunkToGen which is a number that indicates the first n GIFs that must be taken from the collection to generate the preview.

Example:

const int numbOfPunkToGen = 350;

This way the first 350 GIFs in our collection will be used to generate a preview.

Comments

Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

first time i use i have [gif @ 0x55c74bad1a00] invalid block label and Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used) eror show up and the gif corrupted

but after i remove -ss it can run but another error still remain [gif @ 0x55c74bad1a00] invalid block label for each layer

note : btw i use your original gif

Help creating .mp4 with sound.

Thanks for this repository. I am currently trying to get it working. I am getting the gifs to come out properly but having trouble when trying to add the audio. Maybe a little more detail on that process would help. It seems the tutorial video - which I watched - did not cover that section. Also, is there any way for me to autoloop the final .mp4?

Thanks bro, much luv!

I added you on Discord, please accept my friend request.

Issue when trying to compile myFFmpegConversion.ccp

There is an issue when trying to compile myFFmpegConversion.ccp

There is an undefined reference to extractInteger on line 155 which is causing it to not compile - am I missing something?

I have the latest version of the repo and I am using Linux on Windows.

Many thanks for this repo!

Invalid File Index 2 in filtergraph error?

getting this error when using ./main sol

This works with other sets of layers I'm using, but not with these! also note that there's only 2 layers with 2 .gifs each. just testing them out.

really at a loss and anything helps!

ok i added a background folder with 2 backgrounds and that fixed it. I'm not sure what prompted this error in the first place but it isss what it is.

It zooms the layers, stops the gif after 1 second

Hi!

So i've got a 5second gif for background, and all the other layers are PNGs. It just zooms in a lot for the pngs, even if i modify the scale, what could be the problem? And it resets after 1 second.

(All the layers are the same size)

Conversion not precise and timings are completely off

The combined .mp4 from gifs isn't the same size as the output:

For example - the input gifs have 2.3s and the combined .mp4 file has 2.4s whilst the exported gif has 2.14s. So this is not matching frames during the process. Attaching the screen:

Having Difficulties running the program in windows

I have installed both FFmpeg and MinGW. I have tried running the program on windows but it is still not working. I have gotten an error in the src folder (main.cpp) under time(NULL).

If you don't mind, would you please make a screen record of how you can run the program in windows and genenerate the GIFS. Even if its just recording without any sound (screen recording). You may upload to youtube then please share the link here.

I'll really appreaciate your help and make a donation.

Floating point exception (core dumped)

Hello, When I run the main script, It doesn't work and I get this message in console : Floating point exception (core dumped)

When I set the randomized bool to true, it works. I want to do it with rarity though. What do I need to cdo ? I checked if the sum of all rarities was 100.

vector collectionSize = {x,y,z}; Are more than two different combinations of the layers possible?

Hello!

Thank you for making this code, I've been using it to make some cool stuff. Is that metamask address 0xaE9d8FD177c22D88159F2773998dB07CAf40693d up to date? I would like to send you an NFT to say thank you. I have sent you a discord friend invite: JuiceGoose#3498.

I am a programming noob, I wanted to know if it is possible to make more than just 2 of the collectionsize layer combinations. For example vector collectionSize = {w,x,y,z}; to create 4 different combinations of the layers? This would be incredibly useful to have. Currently when I try I get a segfault.

Thank you for your help.
