Staircase effect on CX23881 card ?? how to avoid it ??

It is interlaced. Use a De-interlace filter in VurtualDub or AVS filter later. Search for interlace as this would surly have benn discussed before. Good luck. Edge

yeah thought exactly that, but no, the deinterlace in VD makes the picture so bad its terrible :confused:

ok it worked this time, i thinks it all to do with res i ran the Deinterlace @ 640x480 and it got ride of the lines, but a little blurrier. so i figured if its interlaced then it need to be deinterlaced even @ 320x240 which is showing no lines anyway, but that simply makes the picture blurry, doesnt help the coz my question now is, is it possible to make a Capture Card capture interlaced @ certain res and not interlaced @ other resolutions ??? any light shed on this subject, much appreciated

Every capture card will cause interlace if captured with a vertical res. higher than half of max. possible. E.g., you'll get interlaced video for PAL if the vertical res is > 288. There is some old fashioned material(old movies, for example) which is noninterlaced anyway, so it won't be captured interlaced no matter which res. If you want to encode the captured video to vcd, you can configure VDub to discard one field, as you won't need it. Then resize the picture to vcd res.

hmmm okee, very interesting. its max res as stated on the site and box is 720x576 576/2 = 288 (duh!:)) so my 320x240 is the best res to use ?? it doesnt have the lines at all, but isnt as clear as 384x288 384x288 cap ran through VD with Deinterlace filter on does end up somewhat similar to a direct 320x240 cap hmmmm all good to learn, back to some more testing ..... :D thanx

oh, hmmm but theres the interlacing lines like my eg vid up there ^ just not as bad, 320x240 removes all interlace effects, i am confused now :confused: :D

i see you're from australia,and therefore on PAL and therefore you can consider only 2 (two) vertical resolutions: 288 or 576 ! ( you can toy with horizontal resolution (352,480 etc), but using on capture something different than those two vertical resolutions i DON'T reccomend- for PAL off course ) use 576 and you worries are gone! (not to go deeply into explanation why 480 is wron for PAL etc. ) cheers Ivo
