View Full Version : Filtering Advice on AVI Capture

Guys,
I asked some questions about filtering a video a while back and received excellent suggestions that solved my problems. I'm back :)

Recently I have been capturing a series from cable for conversion to DVD. This one has some things that I am not sure if I am handling correctly and am seeking some help. A sample of the video is available here:

(again sorry about the size I capture with a Canopus AVDC100 and 5 min of video is about 1G).

When I 1st encoded this file with HC Encoder as an DV Source BFF with only cropping, and noise filtering (FFT3DGPUI) I got what I would consider ripples on the tops of objects as they moved when viewed on TV. I tried using the AVS filter Deinterlace with blend=false and that seemed to fix most of the problems. As far as can tell the source is not telecined. I have tinkered with the dthreshold and threshold parameters and they have some effect, however I find what I will call ghosting on objects when scenes are panning (the blend setting seems to affect this somewhat, false seems better to me).

avisource("N:\Sample\Sample.avi",false)
FieldDeinterlace(threshold=18, dthreshold=7, blend=false)
crop(0,40,0,-40)
FFT3DGPU(sigma=4, bt=3, bh=64 ,bw=64,plane=0)
lanczos4resize(720,480)

Also I have looked at the source frames in Virtualdub with SeparateFields and see things that I think are a little strange see frame 34 (no separatefields) and frame 69 in the separatefields case. I'm not sure, but the field appears to have blending(?) present. Can anyone explain what is going on with this source, and can anyone make any suggestions for better filtering.:confused:

This season's episodes seem to have something different done to the source, since a straight encode seemed to work for previous seasons.

Also are their any PC DVD players that will actually show the video as will be viewed on TV. If I understand correctly, the PC players do a progressive display and some of the artifacts that will show up on TV aren't seen on the PC when viewed? I spend a lot of time doing DVD-RW short copies for viewing on the TV to see if I've gotten what I want multiple trips to and from the l/r. I can use the exercise, but.......:rolleyes:

I appreciate any suggestions or help you can offer.

Thanks in advance,

rcubed:thanks:

yes,
field blending,
try mrestore()

try asking in the avisynth forum section for specific pointers

Immerson,
Thanks for the reply. After I had posted here, I thought it might me more appropriate to do in the Avisynth forum, but didn't want to cross post.

To all, consider this thread closed and I'll move my questions to the Avisynth forum.

Again Immerson, thanks!
