Equipment

  • Webcam - While a webcam is not necessary to run NavaFit, your friends will not be able to see you during your work out if you don't have a webcam. If you want to send high resolution video, you need a webcam which supports 640x480 resolution and if you want to send in HD, you need an HD webcam.
  • Headset - We recommend using a headset (headphones with a microphone) for the best audio quality. Tip: If you have a microphone built into your computer or laptop, just plug in a set of regular headphones to get rid of any echo.
  • Computer - You may notice problems with the video if you are on an older computer, or have a lot of programs running at one time. Tip: Close all unnecessary applications you may be running and if you are using a laptop, make sure it is plugged into a power outlet. A computer with a dual core processor is required to send high resolution and HD video.

Lighting

Because cameras are less sensitive to light than the human eye, it is important to have good lighting when you are using NavaFit. If your video looks dim, grainy or washed out, try adjusting the location and brightness of your lighting. Below are some common problems caused by lighting and some suggestions to fix them:
  • Dim Video
    • There isn't enough light in your room. Try turning on more lights, or move to an area where there is more light.
  • The room is bright but your image is dim
    • This could be caused by having a bright light source behind you. The camera adjusts it's sensitivity to the background instead of you. Try positioning yourself so the light source is in front of you.
  • Grainy Video
    • While this could be caused by a low quality camera, it can also be caused (or made worse) by not having enough light. To compensate for the lack of light, camera's often adjust their sensitivity which creates more grain or "noise" in the image. Try turning another light on, or sitting closer to and facing the light source.
  • Video looks choppy
    • This can be caused by not having enough light in your room, but can also be caused by not having enough bandwidth. Try turning on more lights and if you still have the problem, read the section above called "Bandwidth".
  • Your image looks washed out
    • This is usually caused by a light that is too intense (example: having a light shine directly at your face). Try dimming the light, or reflecting the light off a light colored surface, like a white piece of paper on your desk.

Video Quality: Optimizing your video experience Bandwidth

While you probably already know that you need a broadband connection to use NavaFit, did you know that not all broadband is created equal? Even on the same connection, your bandwidth (the amount of data that can be transmitted in a fixed amount of time) may vary based on factors such as the amount of traffic on the network, the number of people using your Internet connection, and whether you are downloading or streaming something else. Below are three measurements of your connection speed that will influence your video quality.
  • Downstream
    • This is the amount of bandwidth you have coming to your computer from the Internet. Think of this as how wide the road is coming to your house. The more downstream bandwidth you have, the wider the road and the more traffic that you can accept. You should have a minimum of 250kbps (kilobytes per second) downstream bandwidth for a each class participant. For example if you have 1 trainer and 5 class participants you would require 1,500Kbs (which can also be referred to as 1.5Mbs megabytes per second) downstream bandwidth.
  • Upstream
    • This is the amount of bandwidth you have going from your computer to the Internet. Think of this as how wide the road is going from your house. The more upstream bandwidth you have, the wider the road and the more traffic that you can send. You should have a minimum of 250kbps upstream bandwidth. The upstream requirements remain the same regardless of the number of class participants.
