Please: Avisynth script improvement anyone?

[Canon GL-2 Guy]

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:

HD2SD("filename.avi",outputfieldrate=30,outputcolo rspace="YV12")

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.

Thank you.

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

That's the correct storage aspect ratio if you're making a 16:9 NTSC DVD. All NTSC DVD, whether 4:3 or 16:9 use that frame size.
