Can this HD2SD Avisynth script be improved? Please critique& evaluate.
Someone online generously donated this script as I do notunderstand programming or code. Source video is Canon A1s HDV 1080i/30F.
Converting widescreen to SD widescreen.
It's a one liner:
Can this be improved in a material way? Is there anythingmissing which should be included? If so, would you be willing to add more linesto the above as deemed necessary?
A question about the aspect ratio.
I need/my target is widescreen 16:9 and after processing inAviS the file always comes out as 720*480 3:2 per Media Info.
Does it make any difference as my end product is 16:9? Can Iget it there before its further subject to processing with Premiere Pro CS 5.5?
What do the resident experts recommend?
Please advise & contribute. Hopefully this will be an educationalexperience.

Canon's "30f" mode is really 29.97 (or more precisely 30000/1001) as per NTSC. So I think outputfieldrate=30 might be incorrect . People use abbreivations such as "30p", but they really mean 29.97p (or more precisely 30000/1001)
Not sure why you are using HD2SD - the poor scaling issues with NLE's are usually with interlaced material. I guess if premiere had an interpretation with the native stream (some NLE's might get "confused" that it's 29.97p in 59.94i and apply deinterlace, degrading the footage) , you might use another scaling method
When using avisynth , it always outputs "square pixels". You have to interpret the AR in the editor, or the encoder if you are using an intermediate
