gadgevxr Posted November 3, 2007 Share Posted November 3, 2007 Why do moving objects appear like this with lines going through them? Is it simply a case of needing high quality equipment?

amateurandy Posted November 3, 2007 Share Posted November 3, 2007 Why do moving objects appear like this with lines going through them? It's due to interlacing. Link to comment Share on other sites More sharing options...
spider Posted November 3, 2007 Share Posted November 3, 2007 yep, interlacing is the cause, progressive scan cameras would cure this (or so I'm told) not checked it myself though! Link to comment Share on other sites More sharing options...
amateurandy Posted November 3, 2007 Share Posted November 3, 2007 yep, interlacing is the cause, progressive scan cameras would cure this (or so I'm told) not checked it myself though! Or use software that can de-interlace properly..... Now I'm not any sort of CCTV expert (to put it mildly), but I used to see these effects transferring video from my digital video camera to PC, until I got better editing software and configured it properly.

CameraGimp Posted November 4, 2007 Share Posted November 4, 2007 I would be looking at the settings on the recording software/card. The interlacing you are seeing is quite extreme (unless you live by a race track). A way to sense check this would be to view the images straight into a conventional monitor (or TV) rather than through the PC. If you do and the images look better then the problem will be the recorder. Check you have the input set to PAL (assuming you are) and not NTSC then look for anything that mentions interlace. A cheap camera won't produce worse interlace than an expensive one. Link to comment Share on other sites More sharing options...

The interlacing you are seeing is quite extreme (unless you live by a race track). Not sure about the race track. Looks like about 25cm between the 2 images, which translates at 50fps to 12.5m/sec, about 28mph. So it's about right if you live in a 30mph zone.

DownUnderCamMan Posted November 7, 2007 Share Posted November 7, 2007 Try switching your DVR from frame recording to field recording! If you can, this would stop you seeing the smearing on fast moving objects. Thing is not all PC type DVR's will let you change this fundamental setting... Stick to cameras.........CameraGimp! ho ho... Beware the fury of a patient man... Link to comment Share on other sites More sharing options...
