Core AI Concepts

Artificial Intelligence (AI)

Computer systems designed to perform tasks that typically require human intelligence, such as visual perception, speech recognition, and decision-making.

Machine Learning (ML)

A subset of AI that enables computers to learn and improve from experience without being explicitly programmed for every task.

Deep Learning

A subset of machine learning that uses artificial neural networks with multiple layers to model and understand complex patterns in data.

Neural Network

A computing system inspired by biological neural networks, consisting of interconnected nodes (neurons) that process information.

Diffusion Model

A type of generative AI model that creates images or videos by gradually removing noise from random data, commonly used in AI image and video generation.

Generative AI

AI systems that can create new content, including text, images, audio, and video, based on patterns learned from training data.

Training Data

The dataset used to teach an AI model how to perform specific tasks, consisting of examples that the model learns from.

Inference

The process of using a trained AI model to make predictions or generate new content based on input data.

Video Generation

Text-to-Video

AI technology that generates video content directly from text descriptions or prompts.

Image-to-Video

AI systems that animate static images to create video sequences, often used for character animation.

Video-to-Video

AI technology that transforms one video into another, such as changing style, adding effects, or altering content.

Temporal Consistency

The ability of AI-generated videos to maintain coherent motion and appearance across frames, preventing flickering or abrupt changes.

Frame Rate

The number of individual frames displayed per second in a video, typically measured in FPS (frames per second).

Keyframes

Specific frames in an animation that define the start and end points of smooth transitions, used as reference points for AI generation.

Interpolation

The process of generating intermediate frames between keyframes to create smooth motion in animations.

Latent Space

A compressed representation of data that AI models use internally to understand and manipulate features like style, content, and motion.

Character Animation

Character Rigging

The process of creating a digital skeleton or control system for a 3D character model to enable animation.

Facial Animation

The technique of animating facial expressions and movements to convey emotions and speech in characters.

Lip Sync

The synchronization of character mouth movements with spoken audio to create realistic speech animation.

Motion Capture (MoCap)

Technology that records the movement of objects or people to drive character animations, often using sensors or cameras.

Pose Estimation

AI technique that identifies and tracks the positions of key body points (joints) in images or videos.

Driving Video

A source video that provides motion and expression data to animate a character, controlling how the character moves and behaves.

Puppetry

Real-time character animation technique where performers control digital characters through motion capture or other input methods.

Blend Shapes

Pre-defined facial expressions or poses that can be combined and weighted to create complex animations.

Technical Terms

Rendering

The process of generating the final image or video from 3D models, lighting, and effects data.

Real-time Rendering

Rendering that happens fast enough to display results immediately, typically at 30+ frames per second.

Post-processing

Effects and adjustments applied to rendered images or videos to enhance their appearance or fix issues.

Upscaling

AI technique that increases the resolution of images or videos while maintaining or improving quality.

Denoising

The process of removing unwanted noise or artifacts from AI-generated images or videos.

Batch Processing

Processing multiple files or tasks simultaneously to improve efficiency in AI workflows.

GPU Acceleration

Using graphics processing units (GPUs) to speed up AI computations, especially for training and inference.

API (Application Programming Interface)

A set of protocols and tools that allows different software applications to communicate and share data.

Quality & Effects

Deepfake

AI-generated videos that replace a person's likeness with someone else's, often used for face swapping.

Style Transfer

AI technique that applies the visual style of one image or video to another while preserving the content structure.

Morphing

A visual effect that seamlessly transforms one image or shape into another over time.

Warping

The process of distorting or reshaping images or video frames to match desired movements or expressions.

Hallucination

When AI models generate content that appears realistic but contains inaccuracies or fictional elements not present in training data.

Artifacts

Unwanted visual defects or distortions in AI-generated content, such as blurriness, strange patterns, or inconsistencies.

Fidelity

The degree of accuracy and quality in reproducing or generating visual content compared to the original or intended result.

Uncanny Valley

The unsettling feeling experienced when AI-generated characters appear almost, but not quite, human-like.

Workflow & Tools

Prompt Engineering

The art and science of crafting effective text prompts to get desired results from AI models.

Fine-tuning

The process of adjusting a pre-trained AI model on specific data to improve performance for particular tasks.

Pipeline

A series of connected processes or tools used to transform input data into final AI-generated content.

Checkpoint

A saved state of an AI model during training, allowing users to resume from that point or use different versions.

Seed

A number used to initialize random processes in AI generation, ensuring reproducible results when using the same seed.

Sampling

The process by which AI models select and generate content from the probability distributions they've learned.

Guidance Scale

A parameter that controls how closely AI models follow input prompts, balancing creativity with adherence to instructions.

Iteration

The process of repeatedly refining AI-generated content through multiple generation cycles to achieve desired results.
