# AI video, image & voice glossary

> The vocabulary of generative media, defined.

- https://eroq.ai/glossary/text-to-video — Text-to-video — definition: Text-to-video is the generation of a video clip from a written prompt alone. The model synthesizes subject, motion, camera and lighting from the description, typically producing clips of a few seconds.
- https://eroq.ai/glossary/image-to-video — Image-to-video — definition: Image-to-video animates a still image into a video clip: the picture fixes the subject and framing, and a prompt describes the motion. It is the standard way to keep a specific face or product consistent in generated video.
- https://eroq.ai/glossary/camera-move — Camera move — definition: A camera move is how the virtual camera travels during a clip — pan, push-in, tracking, orbit, crane, dolly zoom. In AI video it is prompted, not rigged, and it shapes the feel of a shot more than the subject does.
- https://eroq.ai/glossary/dolly-zoom — Dolly zoom — definition: A dolly zoom moves the camera toward or away from the subject while zooming the opposite way, so the subject stays the same size while the background stretches or compresses. It is the "vertigo effect" from Hitchcock and Jaws.
- https://eroq.ai/glossary/aspect-ratio — Aspect ratio — definition: Aspect ratio is the width-to-height proportion of a frame: 16:9 for widescreen and YouTube, 9:16 for vertical shorts, 1:1 for square feeds, 21:9 for cinema. In AI generation it is a parameter on modern engines and a prompt hint on older ones.
- https://eroq.ai/glossary/negative-prompt — Negative prompt — definition: A negative prompt lists what the model should avoid — text, watermarks, extra fingers, blur. It steers generation away from those features instead of hoping the main prompt implies their absence.
- https://eroq.ai/glossary/cfg-scale — CFG scale — definition: CFG scale (classifier-free guidance) sets how strictly a diffusion model follows the prompt. Low values give looser, more varied images; high values follow the words literally at the cost of naturalness.
- https://eroq.ai/glossary/seed — Seed — definition: A seed is the number that initializes a generation's randomness. The same prompt, settings and seed reproduce the same output, which turns re-rendering into revision instead of a gamble.
- https://eroq.ai/glossary/storyboard — Storyboard — definition: A storyboard is a film planned shot by shot — each scene's framing, action and length in order. In AI video it is the way past the clip-length limit: several clips with one look, played as one cut.
- https://eroq.ai/glossary/take — Take — definition: A take is one rendered attempt at a scene. Rendering several takes of the same prompt and keeping the best is how generated video gets directed rather than accepted.
- https://eroq.ai/glossary/reference-image — Reference image — definition: A reference image is a picture supplied alongside a prompt so the model holds something from it — a face, a product, a style — across new renders. It is the basis of character consistency in AI image and video.
- https://eroq.ai/glossary/first-last-frame — First/last frame — definition: First/last-frame generation gives a video engine both a starting image and an ending image; the model interpolates the motion between them. It is the most precise way to control where a clip ends.
- https://eroq.ai/glossary/voice-cloning — Voice cloning — definition: Voice cloning creates a synthetic voice from a recording so new text can be spoken in that voice. Modern engines need about a minute of clean speech and reproduce timbre and cadence across languages.
- https://eroq.ai/glossary/text-to-speech — Text-to-speech (TTS) — definition: Text-to-speech converts written text into spoken audio. Expressive TTS engines read punctuation as performance and expose controls like speed and expressiveness, producing natural narration and dialogue.
- https://eroq.ai/glossary/speech-to-text — Speech-to-text (STT) — definition: Speech-to-text transcribes spoken audio into written text. Paired with a chat model and TTS it forms a voice conversation loop.
- https://eroq.ai/glossary/prompt-enhancer — Prompt enhancer — definition: A prompt enhancer rewrites a rough idea into a prompt structured the way a generation engine responds to — subject, motion, camera, light, mood — or invents one from scratch.
- https://eroq.ai/glossary/film-grain — Film grain — definition: Film grain is the fine, random texture of photochemical film, added to digital renders to suggest analog capture and to hide the too-clean look of synthesis.
- https://eroq.ai/glossary/director-rack — Director's rack — definition: The director's rack is eroq's set of look controls — film type, era, tempo, camera gear, lens, aperture, palette, lighting — folded into every prompt server-side so a whole film shares one aesthetic.
- https://eroq.ai/glossary/uncensored-ai — Uncensored AI — definition: Uncensored AI describes models that render mature, adult fiction instead of refusing it — governed by a written acceptable-use policy rather than by a probabilistic content filter. It has never meant "no rules".
- https://eroq.ai/glossary/credits — Credits — definition: Credits are a prepaid unit for AI generation: each call costs a flat number regardless of tokens or pixels, which makes budgets predictable. On eroq, 1 credit is about one cent at the entry pack.
- https://eroq.ai/glossary/image-to-image — Image-to-image — definition: Image-to-image edits or restyles an existing picture guided by a prompt, keeping its composition while changing details, style or subject. Reference-guided generation is its most common creative form.
- https://eroq.ai/glossary/model-context-protocol — MCP (Model Context Protocol) — definition: MCP is an open protocol that lets AI assistants call external tools. An MCP server exposes capabilities — like generating a video — that ChatGPT, Claude or a coding agent can invoke in conversation.
- https://eroq.ai/glossary/sse-streaming — SSE streaming — definition: Server-sent events stream a chat reply token by token over one HTTP connection, so users see text as it is generated instead of waiting for the whole completion.
- https://eroq.ai/glossary/tempo — Tempo — definition: Tempo is the pacing of motion within a clip — calm, dreamy, dynamic, tense or chaotic. It shapes how fast subjects and camera move and how much energy a shot carries.
- https://eroq.ai/glossary/anamorphic — Anamorphic lens — definition: An anamorphic lens squeezes a wide image onto the sensor and is unsqueezed in post, producing the cinematic signature of oval bokeh, horizontal lens flares and a gentle widescreen stretch.
- https://eroq.ai/glossary/contre-jour — Contre-jour — definition: Contre-jour is backlighting: the light source sits behind the subject, producing a rim-light halo, silhouettes and lens glow. It is the classic golden-hour look.
- https://eroq.ai/glossary/element — Element — definition: On eroq, an Element is a reusable place, object or style saved once and @mentioned in prompts, so the same location, product or look appears across renders and across a team.
- https://eroq.ai/glossary/character — Character (persistent) — definition: A persistent character is an AI cast member defined once — face references, persona, voice — and reused across images, video and dialogue so they stay the same person in every scene.
- https://eroq.ai/glossary/remix — Remix — definition: Remix reloads a finished render's complete recipe — prompt, model, camera, rack settings, length — into the composer so it can be revised rather than rebuilt from memory.
- https://eroq.ai/glossary/webhook — Webhook — definition: A webhook is a signed HTTP callback a platform sends to your server when an asynchronous job finishes, so you do not have to poll. Video generation, which takes minutes, is the canonical case.
- https://eroq.ai/glossary/workspace — Workspace — definition: A workspace is a shared account space with members, seats and one credit wallet, so a team spends and creates together while each person keeps their own login.
