Download❓ Frequently Asked Questions
What is AI video generation?
AI video generation uses deep learning models to create videos from text prompts, images, or existing video. Technologies like Diffusion Models, GANs, and Transformers power these tools.
What is temporal consistency?
Temporal consistency ensures that objects and styles remain stable across video frames. Without it, AI videos appear flickery with objects changing appearance randomly.
What are diffusion models?
Diffusion models generate images/video by gradually removing noise from random static. They're behind Stable Diffusion, DALL-E 3, Sora, and most modern AI generators.
What is style transfer?
Style transfer applies the artistic style of one image to another, like making your photo look like a Van Gogh painting. Neural style transfer uses CNNs to separate content from style.
What is CFG (Classifier- Guidance)?
CFG controls how closely the AI follows your prompt. Higher CFG = more literal interpretation but potentially less creative. Lower CFG = more creative freedom but may ignore parts of your prompt.
