Shooting something is only half the battle, as you then need to edit it, but that's another thing that smartphones (and tablets) have become surprisingly adept at. For this stage of the process a tablet is preferable as it gives you a larger window to work from, but a phone can still be used.
Whichever you opt for there are a plethora of apps available for your video editing needs. These vary by platform of course, but for example there's Pinnacle Studio for iOS devices, which lets you arrange clips, make precision edits and trims, add effects and add a soundtrack.
Then there's VidTrim Pro for Android, which has a similar selection of features. There are even a few options which cost absolutely nothing. There's a free version of VidTrim for example and a free version of Splice, which is an iOS video editor.
You can even get apps to add effects to your footage or filters to your video camera. For example '8mm Vintage Camera' lets you create a retro look for a price and it was even used for some of the shots in the Oscar-winning documentary 'Searching for Sugar Man'.
Then there's the 'Cinefy - Special FX Studio' app, which includes over one hundred special effects and animations which can be added to your videos.
If you need a soundtrack for your film there are also numerous audio creation and editing tools available for smartphones and tablets, such as the free 'Music Maker Jam' for Android.
Then, once you've pieced it all together you can use something like the 'Intro Designer' to add titles and credits to your movie.
Though while editing on a smartphone is certainly an option, it's not ideal. Botello said: "It isn't viable to expect an editor app on a phone to behave like one on your laptop or desktop.
"You can't compare iMovie to AVID. But just like there are apps to shoot with there are apps to edit on your phone. If you have a news story it's very viable. I can't wait for more apps to come out for editing on smartphones.
"If you are looking to make a cinematic film I urge people to, if they can, use the editor on their computer and treat the film just as any other film they were going to work with."
Kazantsev stated: "Yes but I would not recommend [editing on a smartphone]. If you are in a location where all you have is your smartphone then yes, do whatever is necessary to get the job done.
"So that is an advantage over a traditional camera, the smartphone is the only camera where you can shoot, edit and share with the world from one device."
Speaking of sharing, once you've finished editing you even have access to instant global distribution at no cost, thanks to YouTube and other video sharing sites. In fact some editing apps, such as Pinnacle Studio, even let you share your film straight to YouTube. And of course, at the end of the chain smartphones can even be used to watch your film on.
Swiss army film making
So from filming, through to editing, sharing and consuming, smartphones can handle every part of the film making process and all for little to no more money than the cost of the phone itself- which is something that many people already have. They may not be ideally suited to all parts of the process, but they manage.
In the future they may even excel, as technological advances will make them more viable for conventional film making. So while it might be a niche thing for now, as the cameras get better and more people embrace the potential there could be a not too distant future where smartphone films are regularly playing in a cinema near you.
When asked about whether smartphone films could compete with conventional films Botello argued that "film making began with big reels of film over a hundred years ago. Mobile film making began a few years ago. I think the advances in mobile film making are a clue that if you were going to call it a race and the phone manufacturers wanted to turn it into one, yes...why not?
"I would almost say that conventions are innovating in just about every industry around the world. Mobile technology is opening the doors to everything."
