Avisynth-remove grain problem and Canopus DV codec problem

[SerbianBoss]

Thats work

I was wondering about one thing.

As you know i my script i use separate fields() Interleave(evn,odd) and
Weave().

And i read on avisynth homepage about separate fields and weave. Read this:

Weave is the opposite of SeparateFields: it takes pairs of fields from the input video clip and combines them together to produce interlaced frames. The new clip has half the frame rate and frame count. Weave uses the frame-parity information in the source clip to decide which field to put on top.

So, my question is: Does this change frame rate of video?
Does it video go faster or slower? I use 25 fps for PAL DVD. So in CCE i leave 25 fps and 720x576.

My videos look OK but i just wondering.

best regard

When you separate the fields you get twice the number of frames playing at twice the framerate (50fps). The video remains the same length.

When you then weave the fields back together again, you get the original framecount and framerate (25fps). The video remains the same length.

The reason for this is that you have to apply Convolution3D (and most other "video noise filters") to a field instead of to a frame. A field is one half of a frame so two fields make up a frame but the noise filter cannot be applied to the frame ... must be applied to the field.

That's why we separate the frame into fields ... apply the filter ... then combine the fields back into a frame.
