Yes. You can see it in several videos, both with Zimmer and the Aristocrats, and he talks about it…I think Guthrie Govan is also using Fractal with Hans Zimmer (and on the last Aristocrats tour)?
…but this is a bass, look at the headstock and dimensions!
Are you referring to the video in the OP? I believe it's a Yamaha electric cello - it certainly looks like the cello, not any of their bass models: https://ca.yamaha.com/en/products/musical_instruments/strings/silent_series/index.html The scrolls are very different, as well as the wings.
The first note she plays is consistent with cello tuning (a low D on the C string).
