Just what IS the Diff? PAL DV and PAL STD?

PAL here . .

OK, being sparked into action by another thread, when I open Vegas I can elect to use/configure a project that is either: PAL DV or PAL Standard.

Now, the ONLY difference, I can tell, is PAL DV is LOWER field first and the PAL Standard is UPPER field first. My question is this - why? Have have 2 options when my stuff - as far as I can tell - IS captured 50i and lower field first? Correct? Why should/would I ever need to go UPPER field first?

Is this a dumb question?

TIA,

Grazie

No dumb questions, only dumb answers.

Well....I don't think a pal would give you an STD....

PAL DVD hard disc recorders seem to record upper field first...

Would that mean that NTSC standard would be lower field first?

perhaps grazie, it's for us in australia?

i mean, relative to where you are, you could be upper field first, and we, lower....

interesting question - especially since most (if i remember correctly) pal nle's work upper first... though i stand to be corrected.

I think DV is the only PAL format which has to be Lower Field First. So any other PAL format is Upper Field Field or might be any field order but must not be Lower Field. That's the only difference - I think: PAL DV must be Lower Field First, standard PAL is supposed to be Upper Field First.

I think that's pretty much correct, DV25 is LFF.
All other formats, D1, BetaSP and DigiBeta are all UFF.
Based on that I think ALL PAL and NTSC is UFF but for some reason DV25 is LFF.

Now here's the question, WHY?


Bob.

and no that's not a trick question, I truly don't know why they did it that way around.

So, in all that's Loggie Beard! - just what IS standard PAL? Why have this swappsie option?

. .yes I got the jokes . .very good . . "And also use protection . . "

My Qs still stand . . . as it were . . What is this Standard PAL referring to?

I would say Standard PAL is any PAL format that is not DV. Sounds strange again, but I think that's all about it.

OK, Bob, this wasn't such a dumb Q after all .. I see our posts were seconds apart . .

So, PAL DV = LFF, this "other" PAL, Standard, marries in with WHAT you are saying = UFF.

It hasn;t been till now - 4 years later! - that I've plucked UP the courage to ask this one. I felt that this was something I shouldn't mess with .. others know more than I . . that kinda thing . .

I bet there is a reasonable logical reason for this. Honestly, I am interested to know. 'Cos if there ain't, then Vegas programmers should really strangle this anomaly - NOW!!! It can catch Newbies - it did for me . .

Nothing to do with the Vegas programmers. These are the standard set by the industry bodies.

Ingest PAL from a MiniDV tape and you get LFF.
Ingest PAL from a DigiBeta tape and it's UFF.

If they hadn't made Vegas the way it is, it would be wrong.

Bob.

/edit/ I should have added that the reason its' that way around when you ingest is becuase that's how it's recorded on the tape.

Cheers Bob. Another mystery sorted out! Would've been neat if miniDV was also UFF? No?
