Q3. Can I get better quality video by manually setting the bit rate?
A. We offer variable bit rate versions of the Stack DVR (PRO DVR, DVR2-200M, DV2-400M, DVR2-500 & DVR2-500M.
Our experience so far with VBR is :
- The VBR version needs very fast memory cards.
- Sometimes even the recommended cards have a small % of sectors that don't work & these will cause pixellation in the video picture.
- Unfortunately you can't even be sure that once you have found a good one it will remain OK. This is because some manufacturers have a wear levelling scheme which moves (re-allocates) file locations each time a new file is made.
