What i was trying to say was: Is it impossible to record audio when using 640x480 Interlaced (Not De-Interlace)? I think its just a geovision hardware limitation since Interlace is better quality than De-Interlace.

How do record audio if you are using 640x480 Interlaced? or are you not recording audio.

How can that be? I have tried everything and Rory you said aswell that the De-Interlace is poorer quality. What am i doing wrong?

I was thinking that it may be a labelling mistake aswell. Isn't De-Interlaced images supposed to look better? I have watched live video and still images on the de-interlaced resolution and the quality is very poor compared to the Interlaced. Also when recording Audio you can only use the poorer De-Interlaced resolution, this may be a Geovision hardware limitation. This is the main reason i do not want to use the geovision card.

No its not the VIA chipset, i have an Intel chipset and i get similar poor pictures with De-Interlaced.

Are you running your resolution above 640x480? Because when it gets dark enough at 720x480 it starts pixelating so bad it can cause that to happen. It is a bug that Geo is aware of. 3MB to 130MB, something very wrong somewhere. Small mistake: It goes from 3mb to 65mb. I am running at 720x576 De-Interlace. At night the images are only Black and White whereas in the morning they have Colour, so i was thinking that the images will be a smaller size at night!

Why is it that the size of the recorded files on a Geovision become really large when its dark. I'm using the GeoMPEG codec. During the day the files are only about 3mb for 1 minutes recording and then when it becomes dark the files become about 130mb!!! Massive difference. Is there a way to keep the file sizes to about 5mb for a minutes recording ALL DAY not just during the light periods??

I have Baxall cameras with 680 TV Lines (PAL) so the camera resolution is no problem. Windows XP screen resolution is 1280x1024 at 85Hz. The GV-800 Multicam Panel resolution is 1024x768 (Tried 1280x1024 but does not make any difference). Tried the card on another PC but makes no difference. Maybe its just that the Geovision cards produce poorer images when set to de-interlace?

I am not sure was the definition is right now for de-interlaced but on a geovision GV800 if you select the de-interlaced resolution the image is much much poorer than the normal resolutions.

Using interlaced (the normal resolution selection next to corresponding de-interlace selection) is clearly higher quality. Thats the reason why geovision only let you use the de-interlace because their card probably cannot haddle it without the de-interlace. The images are much more clearer compared to the de-interlaced. I have tested this and it is a fact!

My main point was why do you have to be limited to the poor 720x576 (De-Interlaced) resolution and cannot use the 720x576 (Interlaced) resolution. I am only using two cameras!! If only two cams are used on a GV800 the higher quality resolution should be allowed with Audio recording ????????

using a top of the range CRT PC monitor.

P4 2.6GHz, 1GB ram, Creative sound card, ATI x700 Graphics card, ABit AI7 (Intel 865) motherboard. The picture quality at 720x576 (Not De-Interlace) is poorer than the 640x480 (Interlaced) or maybe even a lower interlaced resolution?

start recording the footage just before the start of the incident (or the last footage you have) then when its finished recording that it will just skip any blank scenes and start recording the footage you require.

Are there any geovision cards that can record at 720x576 (Not De-Interlace) or 640x480 (Not De-Interlace) with audio. The de-interlaced recordings are quite poor quality. Maybe the new Combo cards can do this. like thw GV-1120?
