G22 0 Posted March 31, 2005 Curious... why are most if not all DVR cards I have seen maxed out at 640x480, and many 'standalones' are 720x484 NTSC for example? Is there really that much o diff between the two? Share this post Link to post Share on other sites
rory 0 Posted March 31, 2005 Yes there is a difference. Not much though. The stand alones Live Display is better but their record is not much different. Share this post Link to post Share on other sites
cctv_down_under 0 Posted March 31, 2005 reason is the PCI bus can not handle more than that size, until you buy onboard compression chips, PC's have this limitation. yes there is a bit of difference, not massive but considerable! Share this post Link to post Share on other sites
rory 0 Posted March 31, 2005 I was playing around with Video Capture, with a Card I have, using VidCap, etc. I could set it to 740x480, or lower like 640x480, etc. Anyway, when you Maximize the screen, this is with only one camera at a time, anyway, in 740x480 mode, you do notice a large difference over 640x480. It still isnt as good as the direct to a TV/Monitor, but it is good, for recording to a CD, where as the Stand Alones when you save that video to a CD, it is much more pixelised, as its been compressed for the network (I imagine). Anyway, no compression on 740x480 as an AVI file, 10 seconds, 80MB. Converted using Windows Movie Maker, to a WMV file, 500kb. Just for info incase anyone cares Rory Share this post Link to post Share on other sites
AVCONSULTING 0 Posted March 31, 2005 The standalone recording is usually 720x240. You have to check the specifications carefully since the live view spec's are much better. Share this post Link to post Share on other sites
