Changelog terms: the words release notes use
Each page defines one term as the notes use it and points to entries that show it. As of 2026-09-25.
Definitions follow the makers' own usage where it is consistent.
Where makers use a term differently, the page says so.
1In this section
- Audio-to-video — Audio-to-video generates a clip driven by an audio track, so speech or music shapes what happens on screen.
- Batch and async — Batch APIs accept many generation requests at once and return results later; async endpoints return a job to check on instead of waiting for the video.
- Director models — A director model is trained to follow camera instructions written in the prompt, rather than taking them as a separate setting.
- Extension — Extension continues a finished clip with a further generation that picks up where the clip ended, so it grows in steps.
- General availability — General availability, often shortened to GA, marks a model as stable and supported for production use, after a preview.
- Keyframe — A keyframe is an image the generated video must pass through: the first frame, the last frame, or a frame in between.
- Limited public beta — A limited public beta opens a model to a restricted group of outside users before a wider release, so their feedback can shape it.
- MCP server — An MCP server exposes a service's tools through the Model Context Protocol, so an AI agent or chat client can call them directly.
- Multi-shot — Multi-shot, as AI video release notes use it: multi-shot output holds several shots, with cuts between them, in one generated video or one request.
- Native and upscaled resolution — Native resolution is the size the model renders at; upscaled resolution is a larger size made from a smaller render afterwards.
- Preview — Preview, as AI video release notes use it: a preview is a release the maker marks as early: available to use, but with the maker keeping room to change it.
- Reference-to-video — Generating a video from one or more reference images or clips that fix how a person, object or place looks, with a prompt for what happens.
- Snapshot — Snapshot, as AI video release notes use it: a snapshot is a dated, fixed build of a model.
- Standard and pro modes — Two quality settings on one model, a quicker standard mode and a slower, higher-quality pro mode, often with features arriving in one mode first.
- Turbo, Fast, Flash, Lite, Mini — Faster or cheaper versions of a model released alongside or after it, under names such as Turbo, Fast, Flash, Lite, Mini or Prime.
- Video to video — Video to video takes an existing clip as input and changes its look or content while keeping its movement.
