Convert/save video faster rate with no time-stretch

[rewireproject]

As the title indicates I am trying to save a video file with faster playback speed and higher pitch, ie the output of faster playback with no time stretch. I've managed to save the file with increased playback speed by adding ":rate=1.5" next to " :file-caching=300" in the convert/save window, but I haven't figured out how to save the video with corresponding higher pitch. Does anyone know if there is a command like ":no-time-stretch" that I can add after :rate?

can you show me how you did it? I tried multiple times to convert videos with ":rate=1.5" but it doesn't work, always get the same video speed on the output file
