Bug in TemporalSoften

[Didée]

Hello.

Sorry for bringing bad news, but ...

When I wanted to average 3 frames equally, it didn't work out.

It looks like frame [current_frame - 1] is never considered by temporalsoften.

Simply try "temporalsoften(1,255,255,255,2)" on scenechanges: Ghosting before the change, but not after.

Try "temporalsoften(2,255,255,255,2)" on panning scenes: there are 4 frames blended together, not 5.


While I'm at it:

Overlay(this,that, mode="multiply") gives me nothing but black frames.

I would call you "The Bug Collector" :D

Overlay confirmed - opacity=0.0 gives some kind of result, but it clearly doesn't make sense.

Edit: Multiply is fixed and works more logical now!

Edit: TemporalSoften also confirmed (and fixed).

Keep the reports coming!

The following script does not behave as I expect:
black = BlankClip(color=$000000, length=10, pixel_type="yuy2")
white = black.BlankClip(color=$FFFFFF)
black ++ white
TemporalSoften(5, 255, 255, scenechange=255)
I expect that the video would fade from black into white, but it instead goes from black->gray->black->gray->white...

(I'm using the 2004-03-03 build.)

Since we are reporting bug, there is a bug in all the resizers ( except simpleresize ) : try to resize to a resolution of 674x***, you'll see a green line appear on the right side of the picture. The bug was found on another forum by MWI.

As far as I can test avisynth should send a message error
cause 674 is not mod4.At least in YUY2 and YV12 it is not
a bug.

Yeah, but resize to 674x*** and then to the original resolution, and you'll see the green line appear. Avisynth allows the use of non mod4 resolution for YV12 except for output.

[ARDA]

You're right.My mistake.
Fiters that can't support not mod4 input should
send an error or be fixed.

It's much more subtile than that : the only problematic resolution is 674 : 676, 678 ... 700 work fine.

I cannot reproduce. Could you send an exact script to reproduce?

[Manao]

Source = MPEG2Source("R:\foo.d2v")
output = source.lanczosresize(674,320).lanczosresize(720,576)
return output

Thanks - got it!
