What about the canon SL1? Its the smallest DLSR canon makes. if you're worried about video quality get a DSLR. If you're worried about portability get a compact camera. The Canon SL1 is kind of in-between that... more so leaning in the DSLR direction because it's definitely bulkier than your average compact camera and it IS a DSLR. If you put the 24mm stm lens on it, then you'll have a decently comfortable "DSLR vloging setup"
Also considered the Canon M camera. Its a mirror-less camera with the power of a cropped sensor DSLR, and the portability of a compact camra. However you are limited to a lesser range of lenses (with out using an adapter).
When it comes to video quality its more that just the camera, its also about lighting and post production. And with audio, mic placement is also important. You could just use your phone to get great audio. Lol.
