In Depth: Phoning it in: how the smartphone is disrupting Hollywood

Directors and smartphones

Think of the best smartphone movies and, at best, you'll be imagining that video you once took of your drunken friends trying to push over a cow before falling into a ditch. At least it was in HD.

But you should realize that your smartphone is silently weeping, hating you for not realizing the untapped potential in its high power video camera, as quality and affordability have now aligned in such a way that almost anyone can become a filmmaker.

Don't believe us? Just look at the number of smartphone film festivals that have popped up, from Festival Pocket Films in France, to the iPhone Film Festival and Mobil Film Festival in America and the Olleh International Smartphone Film Festival in South Korea. All of these and more are dedicated to films shot largely or entirely on smartphones.

And filmmakers have already found some success in the field. The first feature length smartphone film, 'SMS Sugar Man', was shot back in 2007 on a Sony Ericsson W900i and since then there have been several other full length movies and numerous shorts and music videos.

Olive

These include 'Olive', which was shot on a Nokia N8 with a 35mm zoom lens and was the first ever smartphone film to get a cinema release.

Also of note is Park Chan-wook's 'Night Fishing' short, which was shot on an iPhone 4 and won the Golden Bear for Best Short Film at the 61st Berlin International Film Festival and 'Departure', a film shot on iPhones by three different directors in three different countries.

There's clearly an appetite for using the medium of a smartphone to create a feature length piece of cinematic glory, but surely a 'proper' camera makes more sense?

Power within

It might seem weird to think that a filmmaker would choose a mobile for their movie, particularly someone established like Park Chan-wook, who's better known for his award winning revenge thriller 'Oldboy', but with the phones we have today it's not that much of a surprise.

Samsung Galaxy Note 3

The Samsung Galaxy Note 3 for example can shoot 1080p video at 60fps or 2160p video at 30fps and soon more phones are likely to have 4K cameras, allowing for higher quality videos across a range of handsets.

Indeed Ruben Kazantsev, the co-founder of the iPhone Film Festival, thinks that this isn't a fad created just because the technology is there.

"Smartphone film making is here to stay," he told us emphatically. "We have been running IFF for over three years now and each year the films get better and better. So as the technology changes so will the quality of the films."

There are real advantages to shooting on a phone too. For one thing, it's a lot cheaper than conventional camera equipment, and it also opens up the medium to a gigantic number of wannabe directors as manufacturers have smuggled this high-power tech into your pocket, removing the barrier for entry.

Not only does that empower almost anyone to be a film maker, but it also makes it easier to counter equipment problems on set. Kazantsev, also a producer on the smartphone film 'Departure', highlighted an issue that only a smartphone could have solved:

"During our filming of departure we had a warehouse space for a limited time and we were down to the last scene with 20 minutes left.

"As we were getting ready to start filming I noticed my hard drive was full and had no time to download the footage to make room, since we had 20 minutes left.

"So I asked our crew 'who has an iPhone?' and almost everyone popped one out of their back pockets. If we did not have the backup cameras/smartphones we would have never gotten the last shot."

Departure

Filming on a phone also allows more risks to be taken as there's less money at stake. And because of their size and portability, smartphones can film almost anywhere, which potentially allows for shots that a traditional camera couldn't get.

A smartphone film called 'Goldilocks' included a scene where a phone was put in a ziplock bag, then placed in a glass and had wine poured on it while filming. If you're feeling a little more flush with cash, solid state microSD cards can be fitted to phones and flung around to get some truly amazing shots – you might smash the phone, but the footage will survive.

Smartphones also allow for more opportunistic filming, allowing you to capture moments that would otherwise be lost because you didn't have your video camera with you, used more often than you'd imagine in professionally produced films.

Of course there are downsides too. Susan Botello, the person behind the Mobil Film Festival, laments the lack of storage space on phones, telling us that "a phone with a great camera for video [but] low space makes it worthless."

She also argues that most phones have a horrible microphone and that the handling of low light situations needs to improve – elements which are being focused on quickly by the likes of HTC, Nokia and Apple with multiple microphones with dual membranes to improve sound quality, and massively upgraded low light sensors in cameras.

Other issues include the fact that the battery will be drained quickly when filming and ideally you'll probably still want to invest in some other equipment, such as lights, microphones and a tripod.

These issues and more mean that smartphone films haven't yet hit the mainstream. They're still fairly few and far between and the need for smartphone-specific film festivals demonstrates that they're not always comparable to more conventional films.

That isn't necessarily a bad thing. These festivals give mobile film "a platform which is a parallel to the traditional industry and open a door to film makers who use smartphones to shoot" according to Botello.

And in their very nature smartphones are going to attract independent and guerrilla film makers. Those who are unable or unwilling to work within the system and who can't afford the major expenses of a standard film.

This leads to unique projects that perhaps wouldn't be seen in mainstream cinema, such as Luke Geissbuhler's 'Space Balloon' short, which involves an iPhone being shot into space and then falling back down to earth, all while filming.

Editing a film on your phone

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.

Pinnacle Studio

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 for just $9.99/AU$10.49 lets you arrange clips, make precision edits and trims, add effects and add a soundtrack.

Then there's VidTrim Pro for Android, which costs $3.99 and 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.

8mm Vintage Camera

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 only $1.99/AU$1.99 and it was even used for some of the shots in the Oscar-winning documentary 'Searching for Sugar Man'.

Cinefy

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.

Music Maker Jam

Then, once you've pieced it all together you can use something like the $2.99/AU$2.99 '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.

Mobil Film Festival

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."


    






LG G2 in line for Android 4.4 KitKat update, but not until March 2014

LG G2 in line for Android 4.4 KitKat update, but not until March 2014

LG has offered the first indication of when its impressive LG G2 handset will be furnished with the new Android 4.4 KitKat update.

The Korean company told Mobile Syrup that the new version of Google's operating system will begin hitting Canadian networks sometime during March 2014.

While the representative failed to mention US and UK networks it seems reasonable that we could expect the update around the same time, if not a little sooner.

Currently the highly-rated G2 remains on Android 4.2.2 Jelly Bean, so fans of the uniquely designed handset will be hoping for a finger or two of KitKat as soon as possible.

Opinion splitter

The handset arrived in the UK last month, following its launch in August, packing a full HD 1080p 5.2-inch display with a pixel resolution of 424ppi.

It's also got plenty of power, thanks to a with a 2.26GHz quad-core Qualcomm Snapdragon 800 CPU and 2GB of RAM.

Aside from its top specs, the G2's calling card is undoubtedly its rear-mounted volume rocker that has so far split opinion among smartphone enthusiasts.


    






LG G Flex could see international rollout starting this December

LG G Flex could see international rollout starting this December

The LG G Flex could start arriving on our doorsteps as early as December if you're living in Europe.

As flagged by 3G.cn, LG has sent out invites for an LG G Flex event in Hong Kong on December 3, which is reportedly to mark an international launch.

Currently, the phone is only available in Korea, where it went on sale in early November for the eye-watering price of 999,900 Korean Won - about $940 in the US, £583 in the UK and AU$992.

The G Flex will be available in France on Orange towards the start of December - that much we know - so we're hoping to see it hop over to the UK around the same time. As for the US, the flexy phone won't be making its way over until early 2014.

Out of shape

The G Flex, LG's first curved phone, has a 6-inch curved OLED, a 2.2GHz quad-core Snapdragon 800 processor, 2GB of RAM and a 13-megapixel camera.

It also has a rear case that can heal itself when scratched, which might be even more exciting than the bendy headline feature.

And let's not forget about the Samsung Galaxy Round, which curves along a vertical axis instead. Although there's no guarantee we'll be seeing that outside of Korea any time soon.


    






In Depth: Your smartphone PIN isn't as safe as you'd think

In Depth: Your smartphone PIN isn't as safe as you'd think

We all know the dangers. The smartphone is the portal to online shopping, our bank accounts and all manner of social network profiling – for many, it is our digital identity.

We know what we have to do: make sure it has a lock code, and never share it with anyone.

But…what if even that isn't enough?

Researchers at Cambridge University recently proposed a method of discovering the PIN on your Android phone by using a malicious app to capture data through your smartphone's camera and microphone. This technique made headlines as it was able to correctly identify a 4-digit PIN, from a test set, 30% of the time after two attempts, rising to 50% after five attempts.

Flanking manoeuvre

Is your PIN really that safe?

The reason this technique, known as a "side-channel" attack, is so noteworthy, is that it circumvents the supposedly secure split between the Android system and the trusted zone on your smartphone.

"Side-channel" attacks use sensors like the gyroscope and accelerometer, or hardware, like the microphone and camera, in order to capture data that's uploaded to a remote server where an algorithm is used to take an educated guess at your PIN.

The 'trusted' part of your phone is separate from the main OS and is designed to isolate sensitive applications, such as banking apps. This is all part of a move to keep sensitive data like your PIN on separate hardware, with companies like ARM inventing technologies such as TrustZone to ensure this stays secure.

However Laurent Simon, one of the authors of PIN Skimmer: Inferring PINs Through The Camera and Microphone, told us, "it's not obvious that the accelerometer or the microphone could be used to leak information…the focus is on the touchscreen, on securing the screen."

How does it work?

This attack involves using the PIN Skimmer app, which is malware disguised as a game, to record users interacting with the touchscreen.

The front-facing camera can be used to capture a shot of the user and determine what they look like when pressing a specific point on screen. This data can then be used to build a model and analyse a video of them entering their PIN.

This is further bolstered by using the microphone to capture audio of the haptic vibration feedback when the user presses the screen in specific spots.

In fairness to phone developers, victims have to download the app and grant it permission to access the microphone, the camera, and the Internet in the Android system.

Once the attacker identifies a likely PIN, they still need the smartphone physically in hand before they can try it, as Simon explained, "in that sense it's limited, you can't do everything remotely; you would need to [inadvertently] collaborate with thieves."

Before you dismiss this idea as never going to happen to you, consider that malware could also be used to track your location, and smartphone theft is at an all-time high. Earlier this year the Met revealed that there are more than 300 mobile phones stolen every day in London alone.

How an app can work out your PIN

How can you protect yourself?

Marc Rogers, Principal Security Researcher at Lookout (WHICH IS?), told us "The absolute, most common, method of compromising your smartphone is installing something from a third-party store that will send out your phone number, your contacts list, your SMS messages, and allow someone to remotely control the phone.

Only download apps from Google Play

"We did a study on the likelihood of encountering this kind of malware and we found in the US and UK that the likelihood of encountering something nasty (a phishing link, adware, or malware) is around 2% to 3%. Your probability of actually encountering malware is about 0.5%."

Those figures are based on data captured from millions of Lookout Mobile users, with Rogers suggesting that to protect themselves users should "stick to [Google's] Play Store and don't go to third-party stores. These don't necessarily have the same level of protection and that's why the probability rises from 0.5% in the UK to around 40% in the Russian Federation and Ukraine."

Simon agreed that "in general Google Play is a safe bet, but that doesn't mean you can't be compromised a different way", citing a Chrome exploit that enabled attackers to gain control over a Nexus 4 and a Galaxy S4 after getting people to click on a link.

Is anyone trying to protect us?

The researchers at Cambridge University are focused on what OS vendors and smartphone manufacturers can do to combat this threat.

The PIN Skimmer research paper suggests various countermeasures, but concedes that one of the main ways is blocking access for various sensors during sensitive transactions, or randomizing the placement of digits on the PIN pad, which would have a detrimental impact on usability.

As Simon suggested, "when you're typing a PIN you don't really need to have access to anything, it takes a few seconds, but it's a big decision for them to say 'we're going to block everything', people might start complaining if they miss a call."

What about biometrics?

Could developments like Apple's Touch ID be the answer? Rogers suggested "it's a really good way to bring security to the masses. It's convenient, it's easy to use and it fits within the user's normal processes.

Touch ID

"The biggest risk you face with the PIN code is that someone is going to trick you into surrendering your PIN, via a website or app. A PIN can be tricked out of someone, but you can't trick a fingerprint out of them. If you marry the two, so that now you need two credentials to gain access, I would rate that security as pretty high."

So biometrics, which also recently debuted on the HTC One Max, are the mobile industry's way of addressing this issue, but it remains to be seen if this is the answer, or if multi-factor authentication is a step further than users would accept for everyday smartphone use.

So in the short term the only option may be to sacrifice some convenience for peace of mind. As Simon said: "anything you can do to make things harder for the bad guys is always a good thing."

Blip: Samsung Galaxy Note 3 won't be going gold - only joking, of course it will

This just in from our existing-phones-in-different-colours correspondent: looks like Samsung is going to release the Note 3 in both red and white gold next year.

It's getting to the point where if you want to stand out from the gadget pack, you'd be better off going for a plain old black handset.

T-Mobile's Sony Xperia Z1 looks like it might have some changes
Nov 28th 2013, 18:41, by Michael Rougeau

T-Mobile's Sony Xperia Z1 looks like it might have some changes

A new pair of photos of the alleged US T-Mobile version of the Sony Xperia Z1 have leaked, indicating it could be well and truly on its way.

Just in time for Thanksgiving, the new renders of the T-Mobile Xperia Z1 appeared on the Chinese forum Digi-Wo.

This is the first time we've caught a glimpse of the front of T-Mobile's US variation on the Z1.

The back features the T-Mobile logo (if you can see it under all those watermarks), but more importantly, there are some subtle changes to notice here.

Change is hard

For one thing, the headphone jack on top appears to have been moved from the center of the phone over to the left side.

In addition the front camera is on the other side of the Sony logo in this new render.

The photo above, courtesy of GSM Arena, highlights these changes with some big, helpful arrows.

Other than that, there appears to be a new hole on the back, likely for a microphone.

Xperia Z1 specs

If (more likely when) the Xperia Z1 hits T-Mobile in the US it looks like it will be slightly different from T-Mobile UK's version.

It's unknown whether the specs will be different as well, but if not the Z1 will come with a quad-core processor, 5-inch 1080p display, 13-megapixel camera, and 2GB of RAM.

In TechRadar's Xperia Z1 review we awarded the smartphone four out of five stars, praising its battery life and some of Sony's customizations to the OS, but decrying its camera, screen and some of that Sony bloatware.

In addition to T-Mobile US's Xperia Z1 we've got our eyes peeled for another rumored variation of the Xperia Z, the Xperia Z1s.
