In this 2008 interview with the band, Joe explains the recording process for the EPs "Party Boobytrap" and "Welcome to Tally Hall", which were then combined into the compilation album "Complete Demos".

"I’ve actually mastered Final Cut Pro, which is video editing software. I used it to record all of our demos. It’s supposed to be for video, but I developed an unusual technique by doing high-quality recordings by building a metronome track in an iPod (it’s sort of complicated) and I had been experimenting with that and when it came time to do the Tally Hall recordings I went with that."

It would not have been version X, as it was not available at the time, but some version of Final Cut Pro was used.

Bill USED to use Final Cut Express 4. He now uses Final Cut Pro X.

Nathan Sharp, also known as NateWantsToBattle, mentions on his website that he uses Apple Final Cut Pro X for video editing.

KARRA mentions that she uses final cut to edit her videos around 8:26

FJO: How many different programs are you using to make this all happen simultaneously? I see you have Max/MSP open.

IM: For the music, this is all Max/MSP; the controller is Max/MSP and Jitter. And this is another effect. And I use GRM [plug-ins], and in that way I relate to physical musicians, but otherwise I’m not really physical at all. For the visuals, it’s a whole bunch of things made using FinalCut and then Flash to put together the animation.

DJ FABI uses Apple Final Cut Pro X for video editing, as shown in their Instagram post showcasing their new studio setup.

Sam features some of his gear in the description of his YouTube videos. He uses Final Cut Pro X to edit his videos, according to the video section of his description. He multitracks his voice in arrangements, some with as many as hundreds of times & accompanying videos of him for each part, sometimes including choreography.
