Is it normal for a processed dv clip filesize to be almost 10X larger? Example: NTCS 29.97 frames/sec 720X480 DV clip that is 11 seconds long is 41.6MB, then after processing that same file is 347MB

What are you using ? VDub ? Another ?
This is typicaly the size of an uncompressed video.
For exemple, with VDub, output is by default in uncompressed mode,
so, if you don't specify any output compression format, you have
an uncompressed video.

So, in that case, what is the problem ????

Your file size is normal for an uncompressed video.
I mean : 720x480x3x11x29.97 = 341801856, for video only.

Having the file filtered or not as nothing to do with it.
If you want a smaller file, select a compression codec in
the output format. If you don't want to have compression
artefec, use a lossless compression codec, like huffyvu
or Lagarith. Lagarith is a little better in compression ration,
but slower than huffyuv.

The original clip before being processed with NV is also compressed DV avi, so I was just assuming after NV has removed the noise, it still would be the same size. BUt if its normal then its all good

Humm... A little explanation of how things works...
When you open a file with VDub, it decompress it for working.
After, it save it, but the saving process is totaly irrelevant from
the opening process. It's not because you have opened a DV
file, that you'll have a DV file in ouput. For this, you'll have to
specify in the compression settings a DV codec, if you have one.

So, yes, it's normal BECAUSE you haven't selected a compression
output format, wich is uncompressed by default.
