Artificial Intelligence (AI) in Combination with vMix Scripting

Right now, everything you’re reading here might already be outdated by tomorrow. The development of AI is advancing by leaps and bounds.

A key example of this development is OpenAI Codex. Codex is considered groundbreaking because it not only generates code but, as a so-called “agent,” can execute complete tasks. It is capable of independently writing functions based on natural language, fixing errors, and even executing longer workflows in the background. OpenAI Codex can work across multiple files and support entire development processes, for example through automated testing or the creation of code changes.

With the increasing prevalence of AI assistants such as Codex (OpenAI) or Claude (Anthropic), the way technical knowledge is used and communicated is changing. Instead of relying exclusively on traditional knowledge repositories such as forums or wikis, users can now ask specific questions and often receive immediately usable answers.

AI can be a valuable support, especially in the context of vMix and its scripting capabilities (VB.NET, HTTP API) – not as a replacement for documentation, but as a complementary tool.

AI assistants are text-based systems that have been trained to understand and generate language. Among other things, they can:

• explain technical issues
• generate or adapt sample code
• comment on and improve existing scripts
• help with troubleshooting
• structure processes or suggest automations

They do not access a vMix system live, but work exclusively with the information provided by the user.

AI can assist in writing vMix scripts, for example for:

• Trigger scripts for shortcuts
• HTTP API calls
• Automation of overlays
• Control of inputs, overlays, or replay functions

Example (VB.NET script for vMix):

 If API.Function(“Fade”, Input:=3) Then API.Function(“OverlayInput1In”, Input:=5) End If 

AI can explain what this script does or extend it, for example, with conditions, timers, or status queries.

• AI is particularly helpful with unfamiliar or older scripts in order to:
• Explain the process step by step
• Comment on variables and functions
• Identify possible sources of error

This is especially useful for users who do not program regularly.

The code itself is not always the problem, but rather the conceptual question:

• “How can I implement this in vMix?”
• AI can help suggest solutions, for example by:
• Combining shortcuts and scripting
• Using the HTTP API instead of internal scripts
• Simplifying complex workflows

As helpful as AI is, it has clear limitations:

• Knowledge of very new vMix versions may be incomplete.
• Generated code is not always immediately ready for production.
• Individual setups must be described precisely.
• AI does not replace testing in real operation.

Note: Every suggestion generated by AI should be checked before live use.

The quality of the answer depends heavily on the quality of the question.

• vMix version used
• scripting language used (VB.NET, HTTP API)
• clear goal of the script
• existing code (if available)
• specific problems or error messages

“I am using vMix 27 and would like to use a VB.NET script to hide the current input when a key is pressed and display overlay 1 with input 5 after 3 seconds. How can I do this?”

• “Can you write me a vMix script?”

Even though AI can provide many answers quickly, a Wiki remains important:

• Verified and structured information
• vMix-specific features
• Proven workflows from practice
• Documented solutions for live operation

AI helps with understanding, a Wiki with permanent reference.
