Is the canon powershot g5 x good for video?
The G5 X is a decent stills compact, but it's only a so-so video camera. Its lens starts at a 24mm-equivalent view, which is tight for vlogging, and I can't confirm from the page that it has a flip-up screen or a microphone input. Those matter more than the sensor. Check both before you buy. Read the video guide for what to look for.
If video is the main job, the Canon PowerShot G7 X Mark III is the better pick. It has a flip-up screen and a bright zoom that reaches 24-100mm equivalent. You'll also want a separate mic, so read the audio notes before you record anything you care about.
