Is smartphone best budget alternative?

It’s no secret that the camera on our smartphones have become more powerful and capable of capturing good quality and clear videos. We all own at least one smartphone. Nowadays, even cheaper phones have a decent camera for pictures and videos. There are people who use their phones for vlogging. However, there are some issues with phones that make it not the best choice for the vlogging. First of all, phone cameras are still unable to capture the details as well as the cameras do. Phones do capture some great details, but they compress the footage so that it does not take up phone memory too much. When converting those videos into a YouTube format or compressing it further for uploads, the videos have become washed out and lose their details and colors. Secondly, phones are not meant to be cameras. Phones can be great for taking pictures of videos, but their main function is not to take pictures or videos. Their main function is to be communication device. We receive messages and calls on our phones that might disrupt our vlogging session or force us to film the portion again. Phones sometimes has very limited storage and their SD cards are slow for saving huge video files. Furthermore, phones often get too hot while filming videos and become laggy and can even restart. The user can end up losing all the footage in the process. These are just few reasons why the phones are not the best alternatives for the vlogging. Do not get me wrong, I do not say it is not possible to use a phone for vlogging. It is possible to use it and many use phones for vlogging. However, those who start getting more subscribers or plan on becoming a more serious vlogger should think to replace their phone camera with something more suitable for taking videos.
