…Also, I just realized you have a third option.
If you’re pretty technical, there’s this Canon firmware hacking software called magic lantern:
That you can load onto a classic EOS M:

The M and its now obsolete lenses it are cheap, and magic lantern gives it rather excellent video recording capabilities. Smaller cameras just can’t compete with its big sensor.
But if you don’t consider yourself much of a tinkerer, I’d avoid that route.


That’s because the sensor is small. Newer phones and mini cameras will all be weak in dim light, outside the absolute extremes like Huawei and Sharp phones.
Check out a Canon EOS M, ~$250 on eBay, or any older SLR that supports MagicLantern firmware. That’s the absolute best way into better indoor video, as its image sensor is like 6-10X the area of a phone’s. Not sure what lens is best for M-mount, but I can look around if that’s of interest.
It’s not as small as a phone, but about as small as a point-and-shoot.
