Hi Gang

Nice to be here! Happy New Year! :2vrolijk_08:

I'm the proud owner of two DVX100B's - been working on a WWII documentary for several years now. All my footage has been captured in 24P Basic/Standard.

Editing is easy in FCP - no special capture settings are necessary and I can combine various clips together, including a tiny bit of stock footage converted to 24P (Film Look), with DV Film Software, and also hundreds of hours of Standard Def archival footage.

But now I've got two questions;
First, is it possible to convert my 24P back to standard Video?

And, (more complicated answer); what would you say about capturing 24P Advanced in FCP? Unfortunately all I know about this particular footage is that it was shot in 24P Advanced.

Take a look at a 3 minute trailer here;

Thank you

To answer your first question im gonna answer the second one first.
24p and 24p advanced straight from the camera is actually wrapped into 29.97fps which is called a pulldown. In 24p Advanced every 4th frame there is 1 frame added. 4frames x6 is 24 and the extra frame 5frames x6 is 30 allowing the footage to play back on any other tape deck. So when capturing, you can either choose to capture removing the extra frames and discarding them for true 24fps (which would be done by capturing 24p advanced with pulldown removal in capture settings i believe)or you can capture at 29.97 or 30fps with the extra frames intact.
Depending on whether you want to edit on a 24fps timline or 30fps will answer that question.

Im not exactly sure of the answer your looking for and im not sure what you mean by standard video, but i will assume you mean 29.97fps or 30fps. Sooo if you want to take 24fps and make it into 29.97fps or 30fps, you could export the 24p or 24p advanced footage adding in the "pulldown" when you export in your export settings. Although this is not true 30p it is editable in a 30p timeline.

Some one on here probably has a link to a better description, but i hope that helped.
 
Not really sure what you mean by "back" to "standard video", but if you mean you want to convert it, like movies are converted for standard definition broadcast, you can do it essentially the same way it's done with film, using 3:2 pulldown. If you read this, it will explain pretty thoroughly: http://en.wikipedia.org/wiki/Telecine

Why do you want to convert your 24p footage? What do you want to do with it?
 
Hello Robert

Why do I want to convert my video?

I was always curious if I could capture '24P', (not advanced), in 30P, (more like normal video), just to see what the video would look like (other than 24P). Everything I've shot has been in 24P and captured in FCP with settings NTSC 29.97. It all has that 'Film Look' as though a frame was dropped, (and that's fine). If I'm stuck with it - that's ok because that's what I chose.

But I wondered if that's all I'd be able to capture/see/edit? In other words once the camera settings were set to record in '24P' does that necessarily mean that's all I'd ever see? Could I ever see/capture/edit this footage in anything but 24P, (as though it were recorded in 30P)? Understand my question?

The other question was in regard to a freind's footage, (from a client), who shot in '24P Advanced'. He wanted to know how to capture this particular footage in FCP.

Thank You
Mike

You can't capture 24p "in 30p" (and you wouldn't want to; 24p doesn't convert well to 30p). You can capture as straight DV video, which is 60i.

As for making the footage look like 30p or 60i -- no, not really. It looks like it does because of the number of times per second a picture is taken -- 24. It has 24 time samples. To look like 30p, you need 30 time samples. To look like 60i, you need 60 time samples.

You can get rid of time samples to go from a higher frame rate to a slower one, but you can't go the other way around.

As for capturing as 23.976 and "going back" to NTSC, that's all you have to do -- export as NTSC. But again, this won't have the "video look." It'll still look like 24p.
 
Thanx for the reply

Yes I suspected, "I'm I'm stuck with it - that's ok because that's what I chose."

The other question was in regard to a freind's footage, (from a client), who shot in '24P Advanced'. He wanted to know how to capture this particular footage in FCP.
He wants to know how/what settings he should use to capture this footage in FCP.
 
24p is generally more desireable than 60i nowadays. Modern displays are almost all natively progressive displays - good luck trying to buy a brand new CRT television nowadays. 60i isn't very well suited for playback on progressive displays, so don't go getting all that disappointed that you didn't shoot "normal" video.
