When you trade feedback after making a video draft, timecodes and descriptions alone can make it hard to point to the exact scene you mean. HyperFrames Studio shows an editing flow where a person looks over a draft the agent made on a shared timeline and preview and refines the parts that need it.
HyperFrames is an open-source framework that makes deterministic MP4s from HTML, CSS, and media. Studio, which sits on top of it, is introduced as a browser-based tool for checking and editing a video's composition. What stands out this time is how it ties the agent's drafting and a person's visual review together on the same editing screen.

The agent makes the draft, and you look at the timeline together
In Studio's shared timeline you can check the order and length of clips and see the result in the preview. Once the agent prepares a draft composition, the person watches the flow of the video and picks the points to adjust. Instead of just typing "a little faster" in a chat window, you can point at the awkward scene on the screen.
The official HyperFrames Studio docs cover the live preview, the clip timeline, and controlling the playback position. You can see the project's foundation and package structure in the official HyperFrames GitHub repository.
Mark a frame and add a short note to convey what you want changed
A request that has to point to a specific moment, like "move the caption up a bit here," can be sent by leaving a mark and a note on the frame. With the marked scene and a short description together, it is clearer to the agent which screen to fix. The editor checks again in the preview and then leaves any further comments that are needed.

What to look at when choosing a video production tool
The heart of HyperFrames Studio is less about handing the whole edit to an agent and more about connecting drafting and a person's visual feedback in one flow. A team that needs an environment where it can leave frame-level comments should look at how the real review process runs through the timeline and preview.
You can see an approach to making explainer videos with code in the anything2explainer video production skill, and a TV opening made with Claude Code and Remotion is an example of agent-and-code-based video production.

HyperFrames Studio bundles the video draft, shared timeline, preview, and frame feedback into one workflow. To see more about how the process of a person reviewing and adjusting an agent's output scene by scene might change, visit the official HyperFrames site and introduction docs.
