I have an iPhone X that I use for filming my projects. Although I find that the shooting capacity can be just as good as an expensive camera. 

Frame-Rate: 

I was unaware of this earlier but I learnt through the studio that the frame-rate of my camera can be changed through settings and it’s easily adjustable. The standard frames per second for a video in Australia is 25 fps, and I was able to change my camera to 24 fps in order to replicate this. 

Zooming: 

My camera can easily zoom in and out by simply pinching the screen while recording.

Focus: 

Like zooming, the camera can focus easily just by simply tapping on the screen whatever you want it to focus on. This is extremely useful and effective, particularly in contrast to other cameras. 

Sound:

However, sound quality of my phone is poor and I usually record it through voice memo after the fact and edit it in. I’m looking on investing in some microphones to increase the sound quality in my videos. 

Applications: 

I primarily use editing software after I have shot my video on my phone to enhance the quality of the shot. I haven’t really found any effective applications to improve my camera.
