Ovo Logger 7.0 - Video Engine
Some usability lab vendors like to tell you about the things you can do with their software. We hope the example below makes it obvious there is not much that Ovo Logger's video engine cannot do.
The above screen shot shows synchronized video output from an Ovo Logger system which is licensed to record five separate video inputs. In this example, these five inputs are:
- Two user computer screens at 1024x768 resolution and 32-bit color.
- Three live video feeds from high-resolution NTSC video cameras.
Ovo Logger can record up to eight video sources, which is more than you are ever likely to need. These sources may be recorded at very high resolution and frame rates. Furthermore, you are not limited to using only certain types of cameras; Ovo Logger can capture video from almost any video device.
- Computer video (i.e., VGA) from any operating system.
- VGA up to 2048 x 1536 resolution and 30 frames per second.
- Live video from NTSC, PAL, USB video devices, and even IP cameras. This makes it easy to integrate Ovo Logger recording technologies into existing usability labs -- we can record your cameras.
Elegant Power
These benefits are achieved without impacting the end-user's experience at all. Ovo Logger's recording technologies:
- Impose no requirements on the user computer's graphics card - perfect for testing games or other graphics-intensive application.
- Impose no load on the user computer's processor.
- Require no software install on the user's computer - useful in today's increasingly locked-down IT environments.
Ovo Logger's video technology lays the groundwork for high-quality video recordings that take up less space on disk than multi-source video that is laminated into a single composite recording. In addition, maintaining video sources in separate files gives you ultimate flexibility in post-test editing. With Ovo Logger, you are never locked into a PIP layout when you are sharing video with your product development team or making highlights.
It should be noted that Ovo Logger 7.0's recording technology is based on the Windows Media architecture, thereby eliminating the need to download proprietary CODECs.
Flexible Deployment
Here are some examples of post-test edits that use the same source video from the 5-source example at the top of the page. The gray backgrounds, yellow captions, caption text, element locations, and yellow borders reflect configuration options that were selected in Ovo Logger.
You could deploy video with just the user screen if you need to share results with an audience for whom user confidentiality is an issue.

Or, you could deploy video that includes the user's face. You can position the video from the face camera anywhere. In this example, it was positioned so it doesn't obscure any of the computer screen.

Finally, imagine you have a usability finding where showing the user's keyboard and mouse usage helps illustrate the problem. You could deploy video that includes the output of the Ceiling Camera. In this video example, the Ceiling Camera output overlays the computer video.
