Vegas 4.0b, Zero sharpen still sharpens

Hi;

I just installed Vegas 4.0b and I've noticed that setting a Video track FX sharpen filter with an amount level setting of 'zero' still sharpens the picture. I remember that there was a thread about this being a problem in Vegas 3, so I (wrongly) assumed this might be fixed in Vegas 4.

Am I missing something, or is there a reason that it is desirable for this filter to work this way?

Thanks;

Duh... OK I'll bite, why would you use a filter and set it to zero? If there is a portion of the video you don't want sharpen applied to it is a simple thing to split the video at that point and have no sharpen filter for that event.

But, it's a simpler thing to just reduce the effect to zero at that point using the keyframes.

That's not just in 4.0b I have noticed that before.

Exactly. I'm converting 2 hour Hi8 'home videos' to DVDs. Some sections of the videos need noise reduction, so I've been cleaning up these sections with a combination of gaussian blur and sharpen.

My preference would be to use the keyframes to turn on and off sharpening (along with gaussian blur) to treat areas as needed. In practice this doesn't work well because A) you can't seem to actually reduce the sharpen effect to zero, and B) you still get a severe performance impact (12x or more) on sections that have a 'NULL' net effect setting. (And why would it make sense for 'zero' sharpening to really mean 'a noticable amount of sharpening' in the first place?).

Today, I end up splitting the video into multiple tracks just for noise reduction/color correction, etc. For me this just makes it more work to accomplish the same goal.
