What is appropriate use of "Reduce interlace flicker?"

I have just recently finished editing a rafting trip that I took some local boy scouts on. I have minimal text effects in the project also minimal pan/cropping and have used "Reduce interlace flicker throughout the entire project. I shot using a Sony TRV900 and all preview material looks great, but the rendered avi has some "choppiness" around outlines of people, road signs are ledgible, but choppy. I plan on only putting this on VHS, but the quality is still not as good as I would expect.

Should "Reduce interlace flicker" be used always, or does it need to be used properly to achieve desired results?

Any guideline suggestions on when to and not to use?

Thanks,

Kade

I only use Reduce Interlace flicker when there is something flickering.
This is usually with stills I captured from the timeline, where there was motion involved - maybe a hand moving, making the still frame "flutter".

It can also happen when there are very thin horizontal lines.

If reduce interlace flicker doesn't fix it, I open the still in PaintShopPro and deinterlace it.

Applying it to everything may well cause quality reduction, as it's a bit like rendering as progressive - ok for computer screen viewing but no good on a TV where it needs the interlacing.

With my first video i spent a lot of time worrying about all sorts of artifacts on the preview monitor, I was using the PC monitor at the time. But I then discovered that most of them disappeared after I'd printed to tape and watched it on a TV.

Of course a whole new lot appeared and I soon learnt about not using 100% red text on black etc. I
'd print to tape, have a good look at it and then start to try to fix things. Obviously using an external monitor is a good start to seeing how the final product is going to look but even that is not 100% the same I find as when you go out to tape and then play that back on a TV.
