Animation capture difficulties

[Tiernan]

I've been happily capturing video for almost 2 years now (mostly PAL/NTSC VHS captures), and only in the past week have I really made any attempt (using the same VirtualDub capture process) to cap animation (Duck Dodgers, in this case), and found that, unlike all of my past capture experience, I have had great difficulty with lost frames, from 1 every 10 seconds to 1 every second or so. With DNR set at about 25% or so (using PicVideo codec at 17, 18 or 19), even the best cap seemed to run for no more than 2-3 minutes before it started to drop frame after frame.

So, my question is:
is there something essentially different about the nature of capturing animation that makes it more difficult to do so without losing frames? Is it something to do with the difference between the originally 24fps non-interlaced nature of animation and how that does not synch with the 29.97fps nature of interlaced video?

I'm interested to hear people's opinions about this.

Video is video (I mean that there is no difference between animation and regular video - most of it originates from 24fps and you cap at 29.97fps). I suspect that you have system issues.

As it happens, my of my VHS caps have been from material that was/is originally video (rather than film), so I thought that might have had something to do with the different response.

Still, I've been looking at LordSmurf's sticky on lost frames, and will be doing some system tweaking to see if it can make a difference.
