Linear Motion Blur?

[ag0n]

I'm making a litle movie from a online game. The raw footage has 90 fps and i would like to create a 30 fps movie, but somehow seems Sony Vegas isn't able to ressample/create a good motion blur.

So, i'm looking for avisynth plugin that could linearly merge 90fps to 30fps (meaning 3:1 or any other input). ChangeFPS/ConvertFPS can't do the job properly either. I've searched for such a plugin but couldn't find.


Thanks in advance.


using a tool to merge tga's (that's how i want -> 3:1 linearly merged):

You should be able to do something with MVTools, but I'm not sure how exactly. Can you provide a sample clip of the original video?

thats mostly the original, i disable the ressample at vegas and activate Super Video Sampling (but it doesn't look as it should).

If that's all you want, you could try:

# load source, then...

a=selectevery(3,0)
b=selectevery(3,1)
c=selectevery(3,2)

d=overlay(a,b,opacity=0.5)
overlay(c,d,opacity=0.66)

#or for a more "central" weighting:
d=overlay(a,c,opacity=0.5)
overlay(b,d,opacity=0.5)

Technically correct, but too much script.

Linear weighting:
Source()
Temporalsoften(1,255,255,255,2).SelectEvery(3,1)

E.g. Gaussian weighting:
Source()
# Temporalsoften(1,255,255,255,2).SelectEvery(3,1).Merge(last,0.25) # <- stupidly wrong (my original post)
Temporalsoften(1,255,255,255,2).Merge(last,0.25).SelectEvery(3,1) # <- edit: this is correct, of course!

Hint: If some merging can be done via Merge(), then use it. Use Overlay() only when necessary.

I would like to thank you both. I've already tested the davidhorman idea and it worked, but i'm going to test Didée and compare.
Avisynth scripts rocks!

But doesn't require an external filter ;)

What or which external filter? :confused:

Erm... nevermind :stupid:

(I clicked on "t" in the AviSynth docs, and it wasn't there - it's grouped with SpatialSoften - doh!)

Nevermind too ... Look again at post#5 above, to see how stupid I am! ;)
