How to create a generative AI video model?

What are Generative AI Video Models?

The generative AI is designed to generate content like ai audio, ai text, ai images, and other ai media as per the prompts given to it. The main objective of the generative AI is to give new data replicating the complete training dataset which is used to train the machine learning model.

The role of the training data is to acquire the essential knowledge of patterns and the predictive capabilities needed for their chosen tasks in the development of artificial intelligence software. 

Generative video models are machine learning algorithms. The video data is artificially created the same as the original video as per how the models let us learn the underlying structure of the video data. 

Types of Generative AI Video Models

There are so many types of generative AI video models. However, some of the most popular generative models are as follows. 

1.Generative Adversarial Networks

Generative Adversarial Networks are based on the two-part model where the first part is the generator. This generator is used to generate fat data. The second part is the discriminator which evaluates the authenticity of the fake data. The main objective of the generator is to produce fake data and convince the discriminator that it cannot tell the complete difference between real and fake data.  

2.Stable Diffusion Models

Stable Diffusion Models are known as flow-based generative models. They are designed to transform the simple random noise into structured and complex data. They define a series of very simple transformations known as flows to gradually change the random noise into the desired content.

3.Autoregressive Models

Autoregressive models make data one piece at a time. They generate one word in a sentence at a time. They predict the next piece of data as per the previous pieces.

4.Variational Autoencoders

Variational Autoencoders successfully work by encoding the complete training data into the low-dimensional representation and decoding this latent code back to the original data space for generating the new data. The goal of this generative video model is to find the best latent code for generating the data same as the original data.

Steps to Create a Generative Video Model Data Collection

Everyone with an expectation to reap benefits from the efficient use of generative AI video models has to know how to create a good generative video model data collection first.

1. Pre-processing Model selection

Many users of the advanced tools associated with automatic video generation can create a generative video model data collection. It acquires a large collection of video dataset that represents the genre of videos they wish to generate.
They must eliminate noisy and irrelevant videos to pre-process and clean the video dataset. They have to ensure that they have high-quality and relevant videos. They can split the video dataset into validation and training sets for the evaluation and training of the model.

2. Architecture Design

You have to select appropriate generative model architecture for video generation, especially generative adversarial networks, variation autoencoders, and other things. Variational autoencoders are generative models with the capability to learn a latent representation of videos and make new video sequences using the sampling from the learned latent space. 
Generative adversarial networks are models made of a generator and discriminator competing against each other to generate realistic videos. Recurrent neural networks are models capturing the temporal dependencies in videos and making sequences as per the learned patterns. Conditional generative models are the models generating videos conditioned on particular input information. 

3. Training the Generative Video Model

In this step, you have to define the architecture and hyperparameters of the chosen generative model. You can train the model using the best and most prepared video dataset. You must optimise it to generate realistic and diverse video sequences. You can enhance your method to regularly evaluate the performance of the model using the validation set which is designed to monitor its progress.

4. Fine-Tuning

You have to fine-tune or refine the generated video sequences to improve the quality and coherence if required. You can apply any needed post-processing methods, especially stabilisation, noise reduction, and color correction.

5. Optimization Processes

The optimization processes involve so many important things to enhance every aspect of the final output. You can assess the generated videos based on different metrics like realism, visual quality, and diversity. You have to gather feedback from all users or domain specialists to assess the usefulness and effectiveness of the generative video model. You can iterate on the video model and make essential enhancements as per the evaluation results and feedback.
