Noise Reduction

Hi, everybody,

I have two little questions, the second of which is probably slightly off topic

1) On the website http://mikecrash.wz.cz I have found a dinamic noise reduction filter for Vegas. Has anyone had the opportunity to test it?
2) What is the field order in the DV file one gets from analog to digital conversion through a camcorder (mine is a Sony DCR-TRV22E). I read some time ago that some analog capture cards swap the field order ...

Thanks to those who will help.

Greetings from Italy

Andrea

2) Lower field first with Canon, Panasonic and probably Sony. You can make a simple test:

1. take a video with a moving subject
2. Set you project to lower field first
3. advance one field at the time forward and check if what you see is always a forward movement. If not (if the subject seems to going back and fourth), try "upper field first".

Thank you ...

you wrote ... advance one field at the time forward ...

you mean one frame, don't you?

DV video is bottom field first. When you encode external analog video, it is encoded as DV video; the source doesn't matter, the encoding sets the field order.

If you encode using a capture card, then depending on the codec used, you may have some other field order, but DV is always bottom field first. (Digital8 is also the same, AFAIK).

As far as the filter, it has been around for a long time (nice to see this adaptation) and it works very well if applied conservatively.
(I haven't tried this version).
