Tank circuit
Every Video VBOX contains a small internal battery to prevent loss of video should the power
supply be interrupted for any reason. This battery is continually recharged during normal
operation.
When the power is interrupted, the unit will start to beep, and the symbol on the right will
appear on the video.
If after 5 seconds the power is still not present, the unit will close the Video file and shut the box down safely.
File formats
The Video VBOX will log either to an SD card or a USB drive (requiring cable RLCAB073).
Two files are logged, an ‘.avi’ Video File (compatible with the Xvid codec which is installed with the software package),
and a synchronised ‘.vbo’ data-logging file which contains all of the GPS (and CAN, if applicable) data in ASCII format,
recorded 10 times a second. The files are stored under the ‘media’ folder.
The maximum size of files for SD cards in FAT32 format is 2Gbytes. If you record for more than 50 minutes, a new ‘.avi’
file is created. Therefore a single ‘.vbo’ file can be associated with multiple ‘.avi’ files.
Video format
Standard definition uses 720x576 pixels at 25 frames per second for PAL and 720x480 pixels at 30 frames per second
for NTSC. All video is interlaced, this is the DVD standard as it was originally designed for a scanning line TV set. When
replayed on a Computer screen instead of a TV, you may see ‘motion artefacts’ which are the result of the interlaced
format. When you upload your content to YouTube, or display on a normal television, the interlacing is removed.
Windows Media Player does not render the video as well as other media players, so for better quality, Racelogic
recommend the free, but excellent, VLC player (
http://www.videolan.org/vlc/)
which has a de-interlacing filter (Video
- De-Interlace - Blend).
For a detailed explanation of interlacing also see here:

CAN Channels
All units can log parameters from the CAN bus, basic units can log a single channel, ‘VCI’ enabled units can log up to 32
channels.
