剪辑视频是一个接一个的创意和技术决策。剪辑师必须塑造故事、放置音效、构建转场、调整色彩等等。Invideo（在新窗口中打开）是一款代理式视频编辑器，旨在处理这些工作，同时让人类剪辑师保持控制权。
借助GPT‑6 Astra，invideo看到了更强的能力来规划和执行复杂剪辑，并在时间线上的正确位置放置更改。
“Astra能够以帧级精度规划特定剪辑，这相当令人惊叹。”
——Sanket Shah，invideo首席执行官
规划复杂剪辑并遵循简报
AI代理必须将剪辑师的指示转化为一系列步骤，选择正确的工具，执行工作，并验证结果。Sanket表示，GPT‑6 Astra能够比其先前测试的模型用更少的推理步骤来规划这些操作：“Astra使用的推理集少得多，因此完成复杂工作所需的输出token也少得多。”
Invideo还观察到，随着任务变得更长、更复杂，Astra能够执行多项指令而不丢失剪辑师的原始目标。
选择正确方法并适应变化
GPT‑6 Astra在色彩工作方面尤其有效，在这类工作中，代理必须从校正、调色、重新生成、LUT和隔离等相互重叠的方法中作出选择。例如，在保留人物肤色的同时更改背景，需要代理在将色彩应用到其他地方之前，跨帧隔离并跟踪该人物。
“早些时候，我们看到调色和色彩校正任务有非常高的失败率。借助Astra，成功率提高了约三倍，”Sanket说。
创建完全可编辑的自定义效果
GPT‑6 Astra还帮助invideo将描述和视觉参考转化为自定义效果。代理可以为素材编写量身定制的效果，将其放置在时间线上，并添加控件，让剪辑师对其进行细化。一天之内，几位Invideo剪辑师使用该模型创建了大约50个效果。
借助使用GPT‑6 Astra的invideo代理，创意专业人士可以继续掌控故事、自己的品味和最终剪辑，而不必在繁琐的规划和逐帧工作上耗费数小时。
Editing videos is one creative and technical decision after another. Editors have to shape the story, place sound effects, build transitions, adjust color, and more. Invideo(opens in a new window) is an agentic video editor designed to handle that work while keeping the human editor in control.
With GPT‑6 Astra, invideo sees greater capability to plan and execute complex edits and place changes at the correct points in the timeline.
“How Astra can plan a particular edit on a frame-level accuracy is quite stunning.”
—Sanket Shah, CEO, invideo
Planning complex edits and staying on brief
The AI agent must translate the editor’s direction into a sequence of steps, choose the right tools, execute the work, and verify the result. Sanket says GPT‑6 Astra can plan these operations in fewer reasoning steps than the models it previously tested: “Astra is using far fewer reasoning sets and thus output tokens to complete complex work.”
Invideo also observed that Astra can carry out several instructions without losing the editor’s original objective as the task grows longer and more complex.
Choosing the right approach and adapting to change
GPT‑6 Astra is especially effective when it comes to color work, where the agent must choose from overlapping approaches such as correction, grading, regeneration, LUTs, and isolation. For example, changing a background while preserving a person’s skin tone requires the agent to isolate and track the person across frames before applying color elsewhere.
“Earlier, we saw very high failure rates for color-grading and color-correction tasks. With Astra, the success rate improved about three times,” said Sanket.
Creating custom effects that remain fully editable
GPT‑6 Astra also helps invideo turn descriptions and visual references into custom effects. The agent can code an effect tailored to the footage, place it on the timeline, and add controls that let the editor refine it. In one day, a few Invideo editors used the model to create about 50 effects.
With the invideo agent using GPT‑6 Astra, creative professionals retain control of the story, their taste, and the final cut without losing hours to the tedious planning and frame-by-frame work.
