Terrible low-light autofocus in camcorder mode topic

My Nexus 5 is horrendous at focusing in camcorder mode in low light situations. I am often recording my kids at home at night, and I can never get it to focus. It is extremely frurstrating.

I didn't record this video, but I found it and it shows exactly what I am experiencing.

Can anything be done about this? It's making me hate this phone.
