Using the Mobile Media Toolkit to Create Great Content

Posted by AnneryanHeatwole on Aug 04, 2011

MobileActive.org recently launched the Mobile Media Toolkit, a resource for professional journalists and citizen reporters who want to use mobile phones to create and share news about the world around them. If you want to learn more about using your phone as a media tool, the Mobile Media Toolkit has guides, how-tos, and real-world case studies that can help you learn the best tips, tricks, and tools for mobile reporting.

One of the sections of the Mobile Media Toolkit focuses on creating content – using a mobile phone for photography, audio, and video recording. The section focuses on basic feature phones and smartphones, so the content is applicable to a large number of users.

Creating Audio:

Mobile phones, as an audio medium, are excellent tools for creating audio content. From radio broadcasts, to podcasts, to audio slideshows, anyone can use a mobile phone for audio reporting. In order to use a phone for audio reporting, users can do any of three things:

  1. Use the calling function of the phone to leave an audio message on a service that records your call.
  2. Record audio directly onto your phone through its microphone.
  3. Use software or applications to record phone conversations.

While creating audio, it's important to have a good recording environment, which means minimal background noise and ambient sound (such as from air conditioners or fans in a room, or traffic in outdoor settings). Using an extrenal microphone (rather than the built-in mic on the phone) can help cut down on ambient noise as it picks up sound more directly. For recording phone calls, you should warn your interviewee first, as in many states and countries, it is legally required to tell someone before recording them.

Using mobile phones to record audio is simple and sharable, and should be a skill in the repetoire of any mobile journalist. The Mobile Media Toolkit has much more information on recording on audio, including how to edit audio, how to publish and share it, and case studies on how different organizations around the world are using mobile audio reports.

Creating Video:

Videos are a great way to document the world around you, and the ubiquity of mobile phones with video capabilities means that the opportunity for journalists and citizen reporters to capture great video is always growing.

Creating good videos off a mobile phone can add a dynamic boost to news reports, or present a stand-alone story. When recording video, try to some of the Mobile Media Toolkit's advice for creating videos:

  1. Hold the phone in landscape mode (held horizontally rather than vertically) while recording; most online video players are designed for landscape videos, so filming in this format means you'll get the most from the scene.
  2. Keep the camera stable; stability is key for smooth video. Use a tripod if you have one, if not, then steady your arms on something solid or film in a sitting or kneeling position.
  3. Use an external microphone for better sound quality.
  4. Check the lighting. If you're filming outside, keep the sun behind your subject; if filming inside, then make sure your subject is lit from multiple angles to avoid shadows. 
  5. Film on the highest resolution you have available – if you are not directly uploading/live-streaming the video from your mobile phone, you can always compress the video later on a computer when editing if you need a smaller file size.

There are several options for editing mobile videos; some phones (like the iPhone and the Nokia N series) have built-in editing packages, and smartphone users with iPhones or Windows phones can download third party editing applications. Users can also upload the videos to a computer for richer editing options.

Taking Photos:

Much of the advice for taking pictures is similar to the advice for taking good videos:

  1. Make sure you have lots of light on your subject to compensate for the small phone lens.
  2. Keep your phone stable in order to reduce blur.
  3. Keep the lens clean. The lens on camera phones can get dirty quickly as it is often less protected then the lens on a traditional camera. Remove dirt and debris so that your pictures aren't marred. 
  4. Try not to use the zoom on the camera; photos will be in a higher resolution if you move in to take the picture or later crop the photo in photo editing software.

The Mobile Media Toolkit has links to reviews of the best camera phones, helpful videos on taking good pictures, and advice on the kinds of editing applications and software.

The section also has information for reporting from smartphones, covering everything from how smartphones can be used for live and semi-live reporting, social media applications, personal management (such as taking notes, recording calls, or scheduling interviews), and a summary of applications for a variety of handsets (Symbian, RIM, Android, iPhone, and Windows).

From Bollywood to BBC, Bubbly is a Voice in the Audio Blogging World

Posted by MelissaUlbricht on Aug 20, 2010
From Bollywood to BBC, Bubbly is a Voice in the Audio Blogging World data sheet 8139 Views

Bubble Motion, a provider of mobile messaging and social media applications, launched Bubbly this year in India, making strides in the mobile audio blogging world. Audio blogging is a form of blogging in which the medium is audio content. Bubbly works by call and record, and thus can be adapted in areas with high mobile penetration and low Internet access, such as India.

A Bubbly user calls the service and through an integrated voice response (IVR) menu can record a name and message, usually less than 30 seconds. When other users choose to follow a user’s posts (or “Bubbles”) they receive an SMS message every time new audio content is added. A video by Pi Social Media on YouTube demonstrates how to record and listen to a Bubble; this one about an office party meet-up.

MobileActive.org spoke with Bubbly and the BBC, a user of the service, to find out how it works.

Basic Information
Organization involved in the project?: 
Project goals: 

Bubbly is a mobile-based service that allows users to record voice content and follow the voice content of others.

Brief description of the project: 

Bubble Motion, a provider of mobile messaging and social media applications, launched Bubbly this year in India, making strides in the mobile audio blogging world. Audio blogging is a form of blogging in which the medium or main content is audio. Bubbly works by call and record, and thus can be adapted in areas with high mobile penetration and low Internet access, such as India.

A Bubbly user calls the service and through an integrated voice response (IVR) menu can record a name and message, usually less than 30 seconds. When other users choose to follow a user’s posts (or “Bubbles”) they will receive an SMS message every time new audio content is added.

Target audience: 

Because it works in close partnership with mobile operator providers, Bubbly users must be on a network that offers the service. Bubbly is currently deployed in India. The Bubble Motion group plans to expand next to Indonesia, the Philippines, and Japan.

Detailed Information
Status: 
Ongoing
What worked well? : 

The Bubbly service works closely with mobile operators, so it is able to leverage the billing systems of providers to have a built-in business model and collection system. It also allows people in regions with high mobile phone penetration and low Inernet access to participate in social communication via mobile phones.

What did not work? What were the challenges?: 

Use is restricted to subscribers of specific mobile networks. Users also incur either subscription fees or the airtime costs required to record or listen to an audio message. Another challenge is the discoverability of the service, requirig extensive maketing investments. 


Exploiting Mobile Technology in the African Urban Low-Income Informal Music Industry

Abstract: 

Music making and distribution is a large scale phenomenon in urban informal settlements in Africa. The talent, vision and passion of the musicians living in the African slums would be appreciated by the music lovers around the world if only the artists had a chance to practice as well as possibilities for recording and sharing. Furthermore this would contribute significantly to livelihoods of the people living in the slums and to economic development of Africa as a whole given the estimates of the contribution that the informal music industry is already making.

The obstacles discussed we believe can partly be overcome by creative thinking and new technology and we hope that this report works as a source of knowledge and inspiration for researchers and developers to develop meaningful services and support mechanisms for young musicians living in the slums around the world.

What's That Sound? Two Tools Track Noise Pollution.

Posted by AnneryanHeatwole on Nov 24, 2009

From traffic to construction to everyday chatter, noise pollution is a part of city life. But with the ubiquity of mobiles, documenting noise pollution is getting a little bit easier. NoiseTube and LHR NoiseMap are two projects that use mobile phones to record and map instances of noise pollution.

NoiseTube uses crowd-sourcing to monitor noise pollution. Users with GPS-enabled phones can install a free application that measures the noise level wherever they are. Users tag the recordings with a description of the noise, its source, the time of day, and other criteria, and the data is then mapped onto GoogleEarth; in this way participants can use their phones as noise sensors to automatically share information about their city with other members of the community.
