Which Parts of Live-Action Production Can AI Video Replace? Where Are the Boundaries?

AI video has advanced very quickly over the past two years, so quickly that many people have begun to imagine a scenario: in the future, you will not need actors, locations, or a camera crew; one person sitting in front of a computer could complete an entire film. This idea is half right, and the other half is overestimated. To see where the boundaries are, a better approach is to lay out the full chain of film and television production and look at how well AI currently fits each stage. You will find that what AI changes is not the single action of shooting, but almost every other part of the chain besides shooting.

First, look at the stages that make up the whole chain

The production of a film or television work can usually be broken down into these stages:

1. Development: define the story, write the script, and break it down into executable scenes and shots
2. Subject design: turn the characters, scenes, and props in the script into defined visual images
3. Storyboard planning: convert text into a shot list, making clear what each shot captures and how it is shot
4. Material shooting: complete the shooting shot by shot according to the storyboard
5. Post-production: editing, color grading, dubbing and music, subtitles, and outputting the finished film. In the traditional process, step 4, shooting, is the most expensive stage and the one most constrained by physical conditions. The way AI intervenes is actually to greatly raise the efficiency of steps 1 to 3, while providing a parallel way to obtain materials in step 4, and finally offering automated assistance across the whole process in step 5.

Development: AI has the most direct effect

The script stage used to be purely manual work: reading the script, breaking down scenes, organizing episodes, sorting out character relationships, and so on. These tasks do not involve the constraints of the physical world. They are essentially text processing, so AI fits them best. In NadouPro, after a script is uploaded, script parsing directly outputs the episode structure, and the episodes themselves can still be added, edited, and deleted. In other words, the read-and-breakdown process changes from manual organization into an automatic result that can be checked, and people only need to make judgments based on that result. It should be noted that AI output at this stage is structural, not creative. It helps you break the script into an executable structure, but whether the story is good and whether the characters stand up still depends on the script itself. This is also why AI feels most substitutive in the development stage, yet is least likely to cause work homogenization, because the judgment standard still remains with people.

Subject design: from description to defined image

There is one stage in film and television projects that is easy to underestimate: visual consistency. The same character is only a few lines of text in the script. But by the shooting stage, that character must have a defined face, body, hairstyle, and costume, and must remain consistent across dozens of shots. The traditional approach relies on casting, makeup tests, the costume department, and continuity supervisors to ensure this. In AI projects, this becomes an asset management problem. This is also the main reason many AI projects cannot sustain themselves over a long span: no matter how good a single image is, once it enters multiple shots, the character starts to drift. So the essence of subject design is to first fix reusable visual assets. NadouPro handles this by first performing subject extraction: extracting characters, scenes, props, their basic states, and script-related substates from the script. Character images are then generated based on these settings, while states and views can continue to be adjusted. The extracted characters can also be saved into the character asset library and filtered for reuse by name, tag, gender, age range, skin tone, hair color, body type, and other conditions. The value of this process is not that it generates something especially beautiful, but that it turns the same character into an asset with an ID that can be searched. Consistency across shots and episodes depends precisely on this step, not on praying again every time something is generated.

Storyboard planning: converting text into shots

Storyboards are the bridge between the script and shooting. In the traditional process, storyboard artists need to write out each shot’s framing, camera position, movement, and duration based on the script. This is a professional skill. The role of AI here is to produce the first draft. After the script and subject settings are defined, automatic storyboarding can output a shot list. Creators then add, delete, and modify items in the list, and adjust information such as shot size, depth of field, and camera angle through field configuration. One-click storyboard images/videos can then directly produce images or video materials based on the storyboard. The significance of this step is that it moves repetitive labor forward. The bottleneck of manual storyboarding has never been creativity, but filling in dozens or hundreds of shots one by one. Letting the machine produce the draft and people revise it creates a large difference in efficiency.

Material shooting: this is the real boundary

At this step, the difference between AI and live-action shooting becomes clear. AI can generate shot materials, mainly in two ways: one is to generate video directly from text descriptions, and the other is to synthesize multiple reference materials such as images, video, and audio to generate video. The former is suitable for starting from zero, while the latter is suitable for extending and reusing existing materials. But its shortcomings are also clear: continuity in long shots. The generation quality of a single shot is no longer the problem; the difficulty lies in whether the space-time relationships, character positions, and lighting logic between multiple consecutive shots connect properly. Accuracy of physical rules. Complex action interactions, fine hand movements, and real collisions between objects remain areas prone to error. Precise performance control. Subtle emotional layers in an actor’s performance are currently difficult to specify precisely through description. So the realistic answer is not that AI replaces shooting, but that AI and live-action coexist at the material level: shots that can be completed with AI are done with AI, while shots requiring precise control are left to live-action, and the two are brought together in post-production. This also explains one phenomenon: the AI film and television projects that currently work best are often the types that are already suited to AI expression, with strong atmosphere, fast rhythm, short shots, and reliance on concept rather than performance.

Post-production: an underestimated stage

Post-production is the area where AI has penetrated most thoroughly, yet it attracts the least attention. In editing, materials can already be integrated, cut, and edited within the project, without needing to export first and process them in another piece of software. In color grading, intelligent color grading can give video a cinematic color treatment. In sound, music generation includes accompaniment and background music, and music can also be automatically matched based on video content; for dialogue, there is text-to-speech and voice conversion. In subtitles, intelligent subtitles can automatically add dialogue subtitles to the video and burn them into the finished film. The post-production stage is characterized by a high technical threshold and relatively standardized creative components, so the gains from automation are obvious. Color grading, music, and subtitles that once took a creator several days to handle can now be completed within the same workflow.

The real boundary is not technology, but judgment

After walking through the whole chain, you will find that AI covers far more stages than imagined, but in every stage it stops at the same point: it can provide a good first draft, but whether that draft is good and whether it needs to be redone is still judged by people. So the more accurate answer to the question of whether AI can replace live-action shooting may be: it replaces part of the way materials are obtained, but does not replace the concept of shooting itself; it greatly compresses the time cost of development and post-production, the two stages that previously relied most on stacking human labor; it changes the threshold of creation from whether you can make it to whether you know what should be made. This last point may be the most important. When tools are no longer the limitation, what distinguishes creators is no longer execution ability, but aesthetic judgment and narrative ability. This is also why the same workflow can produce vastly different results in different people’s hands.

A self-check checklist

If you plan to use AI to move a project forward, you can first ask yourself four questions:

1.  Is this story suitable for AI? Content that depends on strong performance, complex interaction, and long-shot staging is currently more suitable for live-action shooting.
2.  Have the subject images been fixed? Have the characters, scenes, and props already become reusable assets, rather than descriptions that must be rewritten every time?
3.  Is the storyboard detailed enough? Is the shot list clear enough to execute, rather than just a vague direction?
4.  Have you thought through the post-production stage? Who will handle editing, color grading, dubbing and music, and subtitles respectively, and whether the loop can be closed within the project. Once you have answered these four questions, whether the project should be done and how to do it will basically be clear.
