Vegas Pro Scripting Help on Scene Detection

Posted by Chuck Lao on February 7, 2026 at 9:06 pm

I have hundreds of old hi8 avi files and would like to split them using scene detection. Then, I can import these clips into Lightroom for face detection searches.

I know how to write Vegas scripts but get stuck on how to execute the Split button in the detect scene fx. The google AI’s answer is: not allowed due to security reasons.

There are the Detect Scenes and add to timeline and Detect Scense and add to subclips functions from the context menu when right click on a video file; however, I don’t know the syntax to call these functions (I am using Vegas Prod v19).

I have also tried PySceneDetect tool. Althought it works; however, the output does not support the Video for Windows codec which I use to preserve the original video quality.

Any help is appreciated.

Thanks in advance.

Hey Chuck,

I respect your skill and knowledge, and Java programming sounds like a fun way to solve your problem.

But if you are mainly concerned with face-detection, then it sounds like a long way around via Lightroom, to solve a proplem for a functionality that many editing packages are starting to incoporate as standard option when importing clips.

Last August there was this discussion on the COW A.I. forum:

I one of the posts I refer to Corel Ultimate, which is currently retailing at the full price. If not in a rush, it may be worth waiting for the next discount:

Video Deluxe 2026 (Vegas “cousin” at MAGIX) has AI tools for grouping imported footage.
For then 24 hours they have 33% discount, celebrating 33 years in the business:

With regard to your Google comment, that may come down to where Google is based, and where you are located. As Facial recoignition is a topic for legal debate:

From August 25
“While facial recognition technology is unregulated at the federal level, 23 states<strong style=”font-family: inherit; font-size: inherit;”> have now passed or expanded laws to restrict the mass scraping of biometric data, according to the National Conference of State Legislatures.

Last month, Colorado enacted new biometric privacy rules, requiring consent before facial or voice recognition technology is used, while also banning the sale of the data. Texas passed an artificial intelligence law in June that similarly outlaws the collection of biometric data without permission. Last year, Oregon approved data privacy rules requiring consumer opt-in before companies hoover up face, eye and voice data.”

In some European nations, like Denmark, they are looking to make laws where the individual owns the usage their own face.
That might not be an issue if it is family videos, but Google won’t know that…

Hope that this helps?
