Need to reduce scale, but how much?

This doesn't really apply to final cut pro specifically, but it's what I use to edit so I figure I'd post it here.
I have some footage that after looking at quite a few times I noticed that the shot is really tight and the overscan on TVs would probably cut off parts that are crucial to the shot. So i figured if I reduce the scale it would make the image smaller and centered so that nothing, or not nearly as much, would be cut off. But I don't know how much I should do it by. I know that the amount of overscan that TVs have varies, but does anyone know where a good number to start would be? around 90 percent I'd guess.
Thanks.
 
like you said it probably varies on different monitors.

i would do something 'creative' as a background so if you did see the
edges it wouldnt look like a mistake.

as far as a certain number i would think 90 is a good place to start!

probably any working brand name tv doesn't have any overscan(or it will be something so old that it have all kinds of problem and dimmed and the image is not any good anyway), so u don't need to have safe margins, also u will be in widescreen were top and bottom margins are not needed.
just for ur information, broadcast safe would be 20%, that would be 10% in widescreen with letterbox, that's 5% on each side.

Almost all TVs still overscan... even flat panels... some of them have settings to turn overscan off, but then you aren't looking at 1:1 pixels (like new Panasonic Plasmas).

Title safe is 80% and action safe is 90%. Any NLE, effects program, and even photoshop can show an overlay with both safe areas on your image for reference.
 
no, i think u got it the other way around, in plasma black bars are killers to the plasma, and for that reason they add overscan in the tv so u would not see black bars with either 4:3 or 2.35 or 2.39, it's not broadcast safe settings its something the viewer force to the screen to protect the tv, even if it's the default settings in the tv(so it's the viewers choice).u should not account that in ur safe margin, and that is only applied to aspect ratios outside 16:9, so if ur footage is 16:9, u dont have to even consider it.
small note: i dont like plasmas, and hate cropping movies to 4:3 or 16:9.

wrong...

the overscan on my plasma is exactly at 90% (after putting up a test pattern) and this has nothing to do with other aspect ratios. why? because there is still plenty of black bars with academy and scope ratios. action safe is typically 90%, the overscan on both of my TVs (one LCD, one Plasma, both different manufacturers) are 90%. it's not rocket science.

I have the option to turn it off on my plasma, but I lose 1:1 pixel mapping and see the TC track on some channels. Some HD channels don't pay attention to their borders (NBC I'm looking at you with your strip of bright pixels on the right edge). Overscan is still a factor in broadcast video.
 
sorry, outer edge is not part of the image u got that wrong too(that's a dead part added to the resolution, so digital would ignore it, where analogue would use it, it's not in the image or part of the safe broadcast), the 1:1 pixel means no overscan too(if u think about it, the overscan would be the wrong preportion), and there is a limit to what the tv can zoom in if he can even go from 16:9 to 2.4, that would be something like 34% i think from the sides(and if he did u wont get much of an image u can understand based on the movie, that's way they cut movies to fit to 4:3 in the old days which was bad and 16:9 which i dont like that much), and 1:1 doesn't mean real pixel(it mean what u see in reference to the zoom it will do mentaning the aspect ratio), pixel has a specific size that would be something like 16:10 aspect would have to be 31-32" tv, where all of the lcd and plasma arn't, and the image is blown it's never 1:1 the way u think it is, only monitors do 1:1, i have to go, it might not be typed clearly, sorry.
 
1:1 pixel mapping means there is no scaling involved, it has nothing to do with pixel aspect...

overscan is still a very real issue with broadcast (even HD)

I'm not going to argue with you just for the sake of it. I can't be any clearer than I already have been.
 
1:1 they dont mean it's real pixels, it's a proportion. but it's not real pixels when u view 1080 on a 7" or 40" tv, it's scaled from the start, and the option ur refereeing to will do a second scale.

the outer edge is specific and accounted for in the lcd or plasma, u will get the full image.
it's not an issue.
it's a solution for analogue, safe broadcast borders are for old tvs only.
and broadcast is quite outdated anyway, other solutions with todays technology can be far better, specially anything that would unify color and fps to everyone.
