Decomb Plugin for Avisynth Tutorial
Quote:
Trying to determine vthresh value by serving this into Vdub. The capture is inpattern and all frames above the vthresh value are shown as interlaced with white deinterlacing motion map. Frames below the vthresh value are shown as progressive depending upon the vthresh value used. How do I select the optimum vthresh value if all frames below the vthresh value are shown as progressive regardless of the value I choose? I just can't figure out how to use this. |
Hi,
The optimum value is the one that correctly deinterlace interlace frames, and don't find combed zone, where they don't exist... Salu2 Fabrice |
Maybe I am not being specific enough.
I have a 29.97 analog capture that shows interlaced frames. Most of it is in pattern. I am trying to use DecombTutorial to arrive at the correct vthresh value in: Telecide(order=1,guide=1,post=3,vthresh=31,show=true) I have a frame that shows: vmetrics: 35 32 207 [chosen=32]. It shows white deinterlacing motion map and [interlaced] [out of pattern]. (I understand the out of pattern). I change to: Telecide(order=1,guide=1,post=3,vthresh=32,show=true) Frame now shows: vmetrics: 35 32 207 [chosen=32]. It shows no white deinterlacing motion map and [progressive] [out of pattern]. (I understand the out of pattern). Obviously, the vthresh value deinterlaces all frames with chosen<=vthresh and renders them progressive. Any vthresh value for this frame >=32 deinterlaces. :?: How do I determine the optimum vthresh value for all frames. The [chosen=] varies from 16 to 125 for a set of frames as I step through. |
