I just tested the "Force Film (fieldop=1)" option on DGDecNV and I got mixed result.
1 - It's fast, more than double the speed of my avisynth script that does the job, "tfm(order=1).tdecimate()"
2 -Well the result quality is ... well ... shitty!
My source is an TV ATSC Record, MPEG2 1080i, 3:2 pulldown
It can be download here -> http://www.megaupload.com/?d=BYKWAFV0
My normal avisynth script that I use
Code: Select all
LoadPlugin("C:\video\tools\dgdecnv\DGDecodeNV.dll")
LoadPlugin("c:\video\tools\avs\ColorMatrix.dll")
LoadPlugin("c:\video\tools\avs\autocrop.dll")
LoadPlugin("c:\video\tools\avs\TIVTC.dll")
DGSource("C:\Users\slomorbo\Desktop\test\test.dgi")
tfm(order=1).tdecimate()
autocrop(mode=0,wmultof=4,hmultof=2,samples=10,aspect=0,threshold=40,samplestartframe=0,leftadd=0,rightadd=0,topadd=0,bottomadd=0)
Spline36Resize(1280,720)
That give me a normal looking picture like this ->
My avisynth script that I use to test the nvidia's inverce telecine filter,
Code: Select all
LoadPlugin("C:\video\tools\dgdecnv\DGDecodeNV.dll")
LoadPlugin("c:\video\tools\avs\ColorMatrix.dll")
LoadPlugin("c:\video\tools\avs\autocrop.dll")
LoadPlugin("c:\video\tools\avs\TIVTC.dll")
DGSource("C:\Users\slomorbo\Desktop\test\test.dgi", fieldop=1)
autocrop(mode=0,wmultof=4,hmultof=2,samples=10,aspect=0,threshold=40,samplestartframe=0,leftadd=0,rightadd=0,topadd=0,bottomadd=0)
Spline36Resize(1280,720)
That gave me a BAD picture quality like this(look at the hand) ->
It seem to me that the result look like a bad quality deinterlacer filter use on an interlaced source. It's even more obvious by looking at the result's video. There is a lot of ghosting...
My NVIDIA GPU is a Geforce G210 with VP4 engine
I'm using the lastest Nvidia Driver(tested with an older one and same thing)
I also use the lastest version of dgdecnv (2039).
What I think is that maybe the GPU does not have not enough processing power (shader) to do a good job? Or maybe it's just that the NVIDIA inverce telecine filter is shitty as hell?
Can someone test this with a more powerfull card that have the same VPx engine?
Can someone confirm or infirm my results?
Thank a lot for your help,
