Allways do deinterlacing before any sort of filtering in the video, except cropping.

Allways do colorspace conversion before the filter that needs that specific colorspace. Not necessarily immediatly before.

In this case you should use ConvertToYV12(interlaced=true) before the deinterlacing filters that require YV12. Or ConvertToYV12() only if you need it for other filters than the deinterlacers.


Never used MPASource, I mux after encoding.

'clip' identifies the clip to be operated upon by the filter. It is optional to specify it and often it can be omitted. Why? Here's what Ben wrote one time:

-----
1. The statements in a script (or function) are evaluated one by one. If the value of a particular statement happens to be a clip, then it's assigned implicitly to the special variable "last", so that it's still available on the next line.

2. If a filter expects a clip as its first argument, and you haven't supplied that clip [as a parameter], then it's taken from the "last" variable.

3. The return value of a script (or a function) is the value of its final line, unless you have an explicit "return".
-----

So, you can say this in verbose fashion:

a=AviSource("movie.avi")
b=Filter(a, ...)
return b

or you can be briefer by using the implicit "last" variable:

AviSource("movie.avi")
Filter(...)

Thank you a lot for neuron2 and bilu!!!!

If I used another filters that i needed to use ConvertToYV12(interlaced=true) this command??

I don't quite understood your question.

Use ConvertToXXX before the filter that needs XXX colorspace.

If that filter is a deinterlacer, use
ConvertToXXX(interlaced=true).

Never place filters before deinterlacers.

errrr, wrong!
what about sharpeners, they should be placed before deinterlacers.
Its also arguable for filters that can validly work on interlaced sources.

SeparateFields()
Sharpen()
Weave()
FieldDeinterlace()

That's nice to know. Allways learning... :D

Thanks.

um......you said,"If used filters that a deinterlacer.""
Will use ConvertToYV12(interlaced=true)that command??

[bilu]

You seem to have trouble expressing yourself in English.

ConverttoYV12(interlaced=true) before deinterlacers

ConverttoYV12() after deinterlacers


No need for interlaced=true after deinterlacers.
