CaptureSync Case Study – Trio Iguaçu

Trio Iguaçu is a talented group of musicians, playing a delightful blend of tango and bossa nova music. We set up a recording session with them in order to produce promotional videos for the trio, as well as to demonstrate the power and flexibility of our CaptureSync multi-camera video recording software.

CaptureSync is software for the Mac that records video and audio from multiple cameras simultaneously, with all feeds synchronised together and saved to a single QuickTime Movie file. CaptureSync is perfect for recording interviews, scientific experiments, psychological research, musical performances, market research, lectures and presentations.

The setup consisted of one main camera to capture the whole group, as well as three auxiliary cameras to provide close-up views of each musician. These close-up views are useful for analysing playing technique or for editing in Final Cut Pro in order to produce an edited movie that switches between multiple camera angles.

Main Camera

As the quality of the group view was the most important, we used a Nikon D3200 DSLR camera with a 35mm lens. This camera provides high-quality 1920×1080 resolution 30fps video via HDMI, which can be recorded by CaptureSync using Blackmagic HDMI input hardware. As we were using a Mac Pro computer, we used the PCI version of their Intensity product, which is part of a range that also includes Thunderbolt and USB 3.0 HDMI-input devices.

A Field Study Using CaptureSync

In a now-famous experiment initiated by the Washington Post, world-renowned violinist Joshua Bell performed undercover in a busy metro station. Using a priceless Stradivarius violin, Bell performed music that he normally plays in front of large concert audiences around the world. The result? Hardly anyone paid much attention to the violinist, or tossed many coins into the open violin case by his feet. The experiment provides a fascinating insight into the importance of context in our experiences of the events around us.

The performance was recorded, but only by a single low-quality camera. What if we wanted to record the experiment properly, from multiple angles, in order to analyse every aspect of the event and people’s reactions? This is the kind of task that CaptureSync is perfect for, and the setup of this hypothetical recording is detailed below.

Comparison of Streaming Formats

The latest version of SecuritySpy supports new streaming formats which significantly enhance compatibility with new and existing network cameras. The following information about these formats will be useful when making purchasing decisions and setting up video surveillance systems based upon SecuritySpy.

Network Streaming Protocols
There are two main protocols used for carrying video and audio data over IP networks: HTTP and RTSP. Using these protocols, it is possible to transmit video and audio in various compression formats (JPEG, MPEG-4, H.264, AAC etc.).
