What exactly does deinterlace do ?

[plainman007]

What should my project settings be when i am capturing video into my system ? Upper field or lower field ? What is the underlying principle one has to keep in mind when choosing a mode ?

Also when im importing a clip ,,, how do i identify wether it is upper field first or lower field first or if its progressive format ?

[Barry_Green]

DV = lower field first.

Progressive footage is neither upper nor lower first, it's progressive.

I didn't realize that DV was always lower field first. What format is upper field first? I guess you really do learn something everyday...

Barry > just say i recieve a clip from someone ? how will i know its a dvclip ? Through properties ? and is there some oter way like properties which can tell you if the file in question is lower / upper / no fields ?

[Barry_Green]

What format is upper field first? .

HDV, for one. There are lots of file formats and codecs out there, quicktimes and mjpg and mpeg and sorensen and dozens of others; it's always good to get the field order right. Vegas has presets for some of the more common formats.

If you received a clip through e-mail or on a DVD-ROM or something? Import it into your project media bin, right-click it and get the properties, it'll tell you what frame size, what codec, etc.

[plainman007]

But frame size and codec have nothing to do with the field order ? Unless i memorize all the codecs and their respective field orders,,, is there an easier way where vegas can show what the field order is ? Or any other way to find out ?

[GenJerDan]

It'll say which field (or progressive) in the properties, too.

[plainman007]

Oh thanks GenJer and Barry.
Ill try the properties thing.

Here is a little app to tell you what type of video it is AND if you have a compatible codec on your machine - Very handy. . .
