bottlenecks, usability issues and development needs in creating and delivering news videos with smart phones
We conducted five user studies on using smart phones with multimedia capabilities for creating and delivering news content. We present here findings on bottlenecks, usability issues and development needs related to mobile news video capture, editing and uplink delivery. The identified bottlenecks for fast and reliable news video publishing are the uplink delivery of videos from mobile context due to the network limitations and throughput of the mobile system. To enhance the technical quality of the created videos, participants wished for high quality lenses, optical zoom, manual adjustments and a possibility to use an external microphone for audio recording. In addition, the form factor of the device should support the capturing by providing a firm grip and enabling moving of the display. For video editing, more functionalities were wished for, which sets a challenge to designing for small screen devices. Furthermore, the battery life-time was found to be too short especially for video editing. Implications for design and development are presented based on the practical development needs and challenges related to the usage of smart phones for news video capture, editing and uplink delivery.
