Hi Everyone
Just a qucik one today.
I am capturing from VCR thru CanonDV (using analogue to digital converter) and then transferring via Firewire to UVS8.
I capture in DV format and use type 1.
Problem is that as soon as you activate the AV-DV on the Camcorder the Camcorder display starts to shake. This is then reflected on the UVS8 screen when you capture.
I have previously been told that this sort of transfer is regarded as coming from a digital source rather than analogue.
Would anyone recommendchanging the field order to upper field first to try to get rid of the shake.
Many thanks

Tony,
I ran across this article some time ago about capturing VHS I have never tried it but maybe deinterlacing would help control your shakes:
"If you search through the internet looking for information on the VHS resolution, you will find basically 352x240 at 29.967fps (Frames Per Second) for NTSC and 352x288 at 25fps for PAL-M. Yeah, right. You capture with that resolution and you get a video that looks terrible. So all those documents were wrong? No, they were inaccurate, or maybe just incomplete. The VHS video works with the interlaced system (not progressive), which means it draws every frame twice on the screen. In fact, every frame of an interlaced video is divided in two fields (the reason for this is a long story that comes from the first TV sets. You can find more information about this in the articles session of www.divx-digest.com). Those two fields mean that every frame carries much more than just 240 or 288 lines of information. If you capture at 352x240 or 352x288 you'll be skipping every second field, which results in only half of the resolution.
If you want your capture to look just like the VHS source (unfortunately it can't look any better), capture at 640x480 at 29.967fps, and then DEINTERLACE it. ... Some experts would say that such a high resolution for a VHS source is a waste of time and space, but I insist: if you like things perfect, try that resolution. "
BTW, I would not change the captured field order.
