Computer Requirements

The quality and configuration of the computer used with the Pro-Trainer software Program is critical to the output and video rendering you will receive.  Our systems include customized computers, configured to meet the exacting standards for high quality video recording and playback.

The standard “business” computer is not designed for video recording and playback purposes.  In addition, we recommend the computer be used primarily for motion analysis and is not the “general use” computer for your business or practice.  It is difficult to find an “off the shelf” computer with the proper components and capacities. The system should be configured and built by a company that specializes in video analysis.

Some key points to consider are:

PC Speed: The computer requires a good processor speed.  It must be capable of handling large amounts of date very quickly as it is transmitted from the video camera.  A slow processor will drop or lose portions of the video signal.  The resulting video will appear “choppy” during playback.

PC Memory: Because of the huge amount of data (bits) required to store video images, the computer’s memory (RAM) needs to be of a sufficient size for this process.  Too little memory and you will experience the same problems as you will with slow PC speed.  The RAM becomes even more important if you are using multiple cameras simultaneously.

PC Video Processor: During the streaming of the LIVE video to the computer, the video is processed through the Video RAM.  In order to meet the high resolution and display needs of the computer, it is strongly recommended the computer is configured with DEDICATED VIDEO RAM.  A good example of this is a “gaming computer” which typically is designed with a separate Video card.  The quality of the card is a very important factor in the computer.

PC Hard drive: The .avi videos (format used for recording of videos) are some of the least compressed videos and therefore require additional storage capability on the computer.

Video Connection: In order to have the FAST, LIVE connection for viewing of videos, the Mini-DV camcorder utilizes the IEEE-1394 protocol, also known as FireWire or I-Link.  Due to hardware limitations, each camcorder requires connection to a unique FireWire card installed in the computer.  In the case of a desktop computer, this means you will typically require one (1) to three (3) FireWire cards installed in the case.  This is important to note, as cards may be designed with up to three (3) connections per card and only one can be used per camcorder.  In order to have two (2) camcorders connected to a notebook computer, you will need one (1) built in FireWire (1394) port and a FireWire (1394) Express card slot (either “34” or “54” style).  Once again, the typical Express Card has two (2) ports, however only one can be used to connect to the FireWire cable.

The type of computer (desktop or notebook) selected is dependent on a number of factors.

The first and most important is how and where you will be using the system.  If you want to set up the Motion Analysis System and use it primarily with a treadmill, or for functional movements within a specific space, you should consider the desktop computer.  This will allow you connect up to three (3) camcorders for more efficient recording purposes.

If you have limited space and or want to use the System both indoors and outdoors (or at multiple locations) you should consider a notebook computer.   CLICK HERE TO DOWNLOAD PDF! pdf button

* The FireWire Express card typically comes with two (2) connections on the card, however, due to the bandwidth requirements for the .avi file format; only one (1) port can be utilized to connect a camcorder.

**An important word about camcorders: With recent camcorder innovations such as DVD and DVR units there has been a lot of confusion and misconceptions with respect to using them for motion analysis. People mistakenly think that because these are the latest units to hit the market that they must be the best. That's simply not true when it comes to motion analysis. These new units are fine for shooting video of junior's birthday party but they don't work for high-speed motion analysis where you want to capture a full 60 to 1200 frames-per-second (fps) and do accurate slow motion/freeze frame analysis.

Here are the camcorder facts you will need if you are going to do serious motion analysis: The only type of camcorder that is suitable for this purpose is a mini-DV unit. The advantage of these units for motion analysis is that they are the only ones that produce low compression digital video (AVI format) transmitted over a Firewire connection. This is essential for good motion analysis. New style DVD and DVR camcorders do not have Firewire connections and they compress the video (called MPEG format) to a point where you lose frame rate and picture quality at the frame level. Mini-DV units produce a full 60 fps and provide the best video thereby retaining full picture quality right down to the individual frame level.

All of our full hardware systems and our Quick-Start kits come with the correct mini-DV style camcorders designed specifically for motion analysis. If you are just looking for software then we recommend that you consider one of our Quick-Start Kits. These kits come with everything you need: software, the correct type of camcorder, cables, accessories and instructions.
