AMPP Prefix Stripper

IronPython 3.4 script for Grass Valley AMPP Framelight X Script Task brick. Removes filename prefixes (the folder path segments) from asset names after they have been organized into virtual folders.

Overview

This script runs after the Folder Organizer in the FramelightX asset ingestion pipeline. It removes the prefix and -- delimiter from the asset name, leaving only the filename.

Example

Input (AssetName)	Output
`BMG--Videos--Clip1.mp4`	`Clip1.mp4`
`NEWS--PKG--Story.mxf`	`Story.mxf`
`IMG--4709.jpg`	`4709.jpg`
`NoPrefix.mp4`	`NoPrefix.mp4` (unchanged)

Environment

Runtime: IronPython 3.4 on .NET 8
Available Objects: httpClient (ScriptHttpClient), job (ScsJob), asset (ScriptAsset), logger (ScriptLogger)
Workflow: Part of the FramelightX asset ingestion Script Task chain

Deployment

Place this script after the Folder Organizer and typically before or after the Proxy Generator, depending on whether you want the proxy name to reflect the original or stripped name.

Notes

The script is safe to run on assets without prefixes — they pass through unchanged.
The stripping is performed on the asset's metadata name, not the filename on disk.
Works in tandem with the Folder Organizer script for the complete prefix-based organization workflow.
