What is an STX file?

An STX file is a video project created by Corel Pinnacle Studio video editing software. It contains video project settings and references to media and other data files the project uses. Corel replaced STX files with .AXP files as the default project format, but Pinnacle Studio still supports STX files.

More Information

Pinnacle Systems initially developed Pinnacle Studio in the 2000s, which is when the software saved projects as STX files by default. However, Corel eventually acquired Pinnacle Studio in 2012 and replaced the STX format (along with the .SCN and .STU formats) with the AXP format.

Since AXP files replaced STX files, the files have become obscure. You will likely only encounter STX files if you are trying to open an old project.

How to open an STX file

While Corel replaced STX files with AXP files, you can still open STX files with Corel Pinnacle Studio (Windows). To open an STX file, select File → Import previous Pinnacle Studio Projects.

How to convert an STX file

Corel Pinnacle Studio can convert STX files to various file types, including the following formats:

  • .MP4 - MPEG-4 Video
  • .MOV - Apple QuickTime Movie
  • .AVI - Audio Video Interleave File
  • .JPG - JPEG Image
  • .PNG - Portable Network Graphic
