avisynth: how to apply colormatrix to vid=FFVideoSource?

[marcorocchini]

Hi

please can anyone help a cat?

vid=FFVideoSource("j:\sfilataESP\sfilata.avi")
aud=FFAudioSource("j:\sfilataESP\audiosfilata.wav")
yadif(1,1)
audiodub(vid, aud)

now I would like add to the video part:

AssumeFPS(25)
ConvertToYUY2(interlaced=true)
ColorMatrix(mode="Rec.601->Rec.709")

but I have to tell avisynth that this lines have to be added to the video part, because there are present vid=FFvideosource... and not the standard FFvideoSource...

How can I do? thanks

and then:

my source is uncompressed .avi interlaced
I need that output of avisynth after the Yadif(1,1) is progressive: for that is it correct that I use ConvertToYUY2(interlaced=true) ?

aud=FFAudioSource("j:\sfilataESP\audiosfilata.wav" )

FFVideoSource("j:\sfilataESP\sfilata.avi")
yadif(1,1)
AssumeFPS(25)
ConvertToYUY2(interlaced=false)
ColorMatrix(mode="Rec.601->Rec.709", clamp=0)
vid=last

audiodub(vid, aud)

vid=AssumeFPS(vid, 25)
vid=ConvertToYUY2(vid, interlaced=true)
vid=ColorMatrix(vid, mode="Rec.601->Rec.709")

poisondeathray's suggestion is easier because it simply uses (the invisible) "last" instead of "vid" which would have to be explicit for every line as seen here.

I need that output of avisynth after the Yadif(1,1) is progressive: for that is it correct that I use ConvertToYUY2(interlaced=true) ?

It's not incorrect in the sense that it would produce garbage but you will squeeze out slightly more vertical chroma detail if you put ConvertToYUY2() somewhere after Yadif, without interlaced=true (false is the default).
