Combining UFF & LFF clips for DVD - field order question

Post by sblum »

My apologies if I have missed this topic, I have done several searches to no avail.

Using VS10 - have been asked to work on a school project of combining video provided by a couple people to a DVD.

Most of video is captured from a mini-dv tape and is all lower field first. However, some of the other video is on mini dvd's and when I import into VS, it is upper field first.

So if I create a DVD from all the clips I have, I will be mixing UFF and LFF?Should I rebuild the mpg clips from the mini dvd's as LFF? It's about half and half on clips that are LFF and UFF - but they all fit on one DVD.

Please advise. Thanks in advance.

You will need to do trial and error. I have sucessfully mixed stuff from my camcorder (LFF) with a few short clips I have recorded via my TV Card (UFF). A lot will depend upon the content.

The main two considerations will be
a. Uprights and sideways movement. If you are panning across a scene and there are trees or lamposts then it is possible that you will get jagged edges or jerkiness during those scenes.
b. Brightness. If the scene that is in the 'wrong field order' is dark - perhaps a night scene, this will also mask any field order issues as opposed to a bright daylight scene where they may be more noticeable.

If using the wrong field order is noticeable, then again you might get away with it by employing a few tricks to mask the problem. You could try placing that scene in a Picture in Picture effect thus reducing its size.
You could also mask some of the effect with cropping or by placing something over the affected part such as a subtitle or logo.
