Avisynth: How to Make a Screenshot from one Particular Frame?

[HAL4711]

Hi guys,

I often wonder how you make a screenshot from one particular frame of different movies (e.g. original and filtered result) to compare the effect of the filter.

Is there a special trick or are you just searching for the same position in the movie manually?

open them into virtualdubmod and use the snapshot entry of the video menu.

Thanks a lot.
Didn't know that there's a mod of virtual dub which can show the Avisynth input/output video.
