hi, We know that PS can run JSX script files directly no using ESTK,why Pr not? it’s also impossible to pass scripts to Premiere Pro on a command line.? such as cmd: "C:\Program Files\Adobe\Adobe Premiere Pro 2021\Adobe Premiere Pro.exe" " C:\Users\test\Desktop\Source.jsx"
Premiere Pro can execute scripts from a command line, but it's definitely not a recommended workflow. "C:\Program Files\Adobe\Adobe Premiere Pro 2020\Adobe Premiere Pro.exe" /C es.processFile C:\Users\bbb\Desktop\test.jsx /Applications/Adobe\ Premiere\ Pro\ \(Beta\)/Adobe\ Premiere\ Pro\ \(Beta\).app/Contents/MacOS/Adobe\ Premiere\ Pro\ \(Beta\) /C es.processFile /Users/bbb/Desktop/test.jsx Executing scripts from within a CEP panel is supported, and recommended.
