Barry: Thick or Thin - I'm locked out!

Thick & Thin business has me confused.
I was under the impression that in SD Thick was preferred in interlace 60i and also 24P (not PA) because it prevented interference problems when viewing on a TV
That Thin was preferred for 24PA or anything where it would eventually be film out or bump to HD, or when using "squeeze" mode in the older pre 16:9 cameras.
Similarly I assume that Thin would be good for all High Def?

But when I am setting up menus today for an SD 4:3 shoot at 480 60i I notice that my vertical detail frequency is an unchangeable Blue default that changes alternately in each of my scene files
#1 Thick , @2 Thin, #3 Thick , #4 Thin , #5 Thick, #6 Thin

What is up with this?

When I go to 720 24PN I am seeing exactly the same thing.
I don't remember being locked out of this menu before.
Have I set something else up wrong?
This camera is capable of hurting the brain!
 
At 480 60i it is locked out because it is always set to thick in that mode to prevent interlace flicker problems. There is only the option to change it in the 30p, 24p, and 24pA modes.

In 720p it's locked out because it's an all progressive format no matter what mode you shoot in, so that option is irrelevant.

I love the fact that Lenilenapi's question was answered by pheboglobi. :Drogar-BigGrin(DBG)

I just like those names.
 
Lenilenapi was the name of the Native Indian tribe in my home town of Paramus N.J. (that's a great name too.)
Actually I would like to switch to using my real name but I can't figure how to change my identity on this forum or to start another from the same computer.

Pheboglobi,
That doesn't explain why my scene files in #2, #4 & #6 are locked @ Thin.

Are you saying that Thick & Thin don't apply to HD at all?

- Lenny Levy........ ( it's not much different is it.)
 
Yes, thick & thin don't apply to HD at all, they're only active in SD.

Something to understand: when a menu item is blue, that does *not* mean that whatever it currently says is "locked in". Instead, blue means that that particular menu item is irrelevant -- there is a default state that is being forced by whatever mode the camera is currently in, and what the menu item says does not mean that that's what the camera is doing.

As an example, look at DV25 REC MODE (or whatever it's called, camera's not in front of me right now) that has choices of DV, DVCPRO, or DVCPRO50. Well, if you are in 480i mode you could set that to DV, right? Then you change your REC FORMAT to 720/24PN. Now look at the DV25 REC MODE: it'll still say "DV", but it's blue.

Well, when you change your REC FORMAT to 720/24PN, you know for a fact you're now shooting DVCPRO-HD, right? You're not shooting DV. So why does it still say "DV" in blue? Because when it's blue it means that the menu setting is not active, and is fundamentally irrelevant to what you're shooting. You cannot change that menu item because it doesn't apply to how you're shooting.

So don't worry about what a menu item says when it's blue; if it's blue, it means that it doesn't apply in your current circumstances.

Only exception I can think of is the synchro-scan shutter speed, which will go blue if you set it to a shutter speed slower than your frame rate (i.e., shooting 30p but trying to set the shutter to 1/29 will cause it to go blue). You can still change that menu setting even when it's blue, but you need to be aware that it's not actually taking effect while it's blue.
 
Thanks Barry. I actually figured that out last night and was about to post an "Oh Now i get it."
It is very confusing though. I spent hours with the synchro scan business a month ago, and was confused that these were different.
It should be a sticky i think. Its not clear in the manual is it?
