Analog capture problems! (screenshots inside)

[hrgiger6]

I am capturing from laserdisc, I am using a usb2800 dvd maker and virtualdub 1.9.7, however I have 2 problems.

1. If I capture at 640x480 I get a fairly good picture but the overscan areas are chopped off too much! I lose quite a bit of the picture. Why is this and will other capture devices not do this or allow adjustment? I made sure "cropping" was set to 0 and off.

2. If I capture at 720x480 I get the whole picture and then some horizontally, but the image suffers terribly for some reason. Lots of blocking or artifacts on diagonal edges. And I still lose the top and bottom.

This 1st pic from a 640x480, no compression avi capture:

This 2nd pic is from a 720x480, no compression avi capture, notice the left and right hand sides of screen the picture that was missing in the 640 capture, but also notice the jaggies! What the heck?

I'm thinking of trying a "Dazzle DVC 107" capture device but am unsure whether it will offer me any relief. Thanks in advance for your input.

The second picture looks like it's going through some bad resizing - try 704x480 instead, it may be closer to the capture device's native timing. It look like it's not very good at resizing anyway judging by how it just crops to achieve 640x480...

Yeah that's kind of what I thought, looks like it got expanded somehow. Unfortunately the thing won't capture at 704. I guess I'll take a chance on the dazzle dvc 107...

Well I picked up the Dazzel DVC 107 and it works great, here are all 3 shots for comparison:

This 3rd pic is from a 720x480 Dazzle DVC 107 device no compression avi capture. The issues I was having are gone, seems the USB 2800 was causing them...

Looking at these pics I noticed that in the 2nd pic (captured with the USB 2800) the fellow with the suit on appears to have a pink shirt (which is not correct) but it appears white in both the 640x480 USB 2800 and 720x480 Dazzle DVC 107 captures. I'm not sure why this happens...
