newbie needs help viewing scripts

[jdefed]

i just started using avisynth, viewing the results with virtualdub. when i write a script using "avisourse" i have no problem viewing the clip, but both input and output are the same. i can't seem to figure out how to view the input as raw footage and the output with the script i've writen in avisynth. i have done it with 2 sessions of v/d open, one wit the raw footage the other with the script footage. if this can be done, then i'll study v/d more closely and try and figure it out. i've read the guides on v/d but must have some sort of mental block.:thanks:

Right, in/out only refers to the results of vdub plugins, not avisynth. Your method is probably the simplest, though you can sort of do it by assigning "orig=last" right after avisource, and ending your script with "stackhorizontal(last,orig)", as long as you haven't resized.

..., and ending your script with "stackhorizontal(last,orig)", as long as you haven't resized.
Exactly that's the way, indeed.

Plus, to mention it once more, the alternative with "interleave(orig,last)" at the end. It's not for viewing both at same time in motion, but for switching forth-and-back between the original clip and the filtered result. Often this is much better suited to visualize the differences made by a filter or filterchain.
