Titlevision Sub Machine
Sub Machine Tools - Batch file converter
Convert subtitle files between any supported format — in bulk. Transform entire project libraries in a single operation, directly inside Titlevision Sub Machine.
Overview
What is the Batch File Converter?
The Batch File Converter is a built-in tool within Titlevision Sub Machine that lets professional subtitlers convert from any supported input subtitle format to any supported output format — all in bulk.
Instead of opening each file individually, choosing “Save As” in a different format, and repeating the process dozens of times, the Batch File Converter processes entire folders of subtitle files in one operation. Select your source files, choose the target format, and let the converter handle the rest.
Whether you’re delivering to Netflix in DFXP, to a broadcaster in EBU STL, or archiving in SRT — you can convert your entire project library in seconds.

How It Works
Three Steps to Batch Convert
The Batch File Converter is designed to be straightforward. No complicated setup — just select, configure, and convert.
Select Source Files
Choose a folder containing your subtitle files, or select individual files. The converter auto-detects the input format of each file (USF, PAC, SRT, EBU STL, etc.).
→Choose Target Format
Pick the output format you need — from SRT for web delivery, to EBU STL for broadcast, to DFXP for Netflix. Set the output directory for the converted files.
→Convert in Bulk
Hit convert and the tool processes every file in the selection. Entire project libraries are transformed in seconds, with full format accuracy preserved.
Command Line Automation
For even more power, the Batch File Converter can be driven from the command line — perfect for scheduled tasks, batch scripts, or integration with other tools.
Titlevision2011.exe convertfile hotshots.usf hotshots.pac
# Batch convert an entire directory to USF format
Titlevision2011.exe convertdirectory c:\subtitles\ c:\converted\ usf
