I'm using the demo version, and pass the neat video setting as a virtualdub plugin in avs. The total frame number are the same for the source and outputted file, but the avs one is 1 frame behind the source. I tried changing the temporal radius, but still the same problem.

It is probably going to be difficult to test due to limitations of the Demo (it may not be able to read that radius from the script), but anyway, please try to change the "preroll" setting in AVISynth. The preroll is supposed to help AVISynth compensate the lag.

Hope this helps,
Vlad

i read the user manual and matched the preroll number to the temporal radius number like this:

If preroll parameter doesn't help then I guess it must be a bug in AVISynth.
Does it all work correctly if you use Neat Video in VirtualDub instead?

yes, if i ran it in virtualdub alone, it works fine.

The problem occurs when i ran it with avs, or ran that script with virtualdub

[NVTeam]

I guess the script in VirtualDub is still using AVISynth and if the bug is in it then the problem shows up anyway. The question is why the preroll doesn't work correctly in AVISynth.

You may want to use VirtualDub alone then. Or perhaps try something like this.

Hope this helps,

thanks the help, i cutted out the first frame and add a frame at the end to align them
