Pixel Mapping
I have some footage shot in 4:2:2 digital SD anamorphic widescreen, which is displaying slight vignettes in the corners when viewed in the windows on the FCP interface.
It is also visible using video playback, (main), and v.p., (preview).
I have taken a look at it on various other monitors and TVs, and because of the overscan
it’s not visible.
However, the newest generation of Flat panels is boasting 1:1 pixel mapping;
I think that’s the term they’re using, which makes me wonder if I should allow for that, and do the dreaded FCP percentage increase, which of course decreases the quality of the image with
each percentage point.
Any thoughts? -

Tracey,
No consumer TVs display edge to edge full-frame, with the possible exception of some video projectors. When exporting for the web or when viewing in FCP you will of course see video that is not intended for “public consumption.”

David,
Thank you.
So what do Sharp and some of the other manufacturers of high end consumer TVs
mean with this claim?
Also, my “for broadcast” supplied tape will also show the shadow, but when viewed
overscan will again CMA?
Just checking
Many thanks,

The 1 for 1 pixel thing is simply a way for the manufacturer to say there’s no scaling and no interpolation going on in their TV. That’s not a big issue, not nearly as important as the panel itself. Besides, some manufacturers have scalers that are so good you’d be better off with scaling.
If you are at all concerned about the vignetting, consider exporting your final via compressor with a very slight upscale, as the scaler in compressor is far superior to FCP. 1 or 2 percent will never be apparent to anyone.
Another alternative is to apply a 1% crop around all the edges in the motion tab.

Well, now I have 3 choices!
Can’t ask for much more than that.
Thanks again.Now I’m wondering what the overscan percentages are and do they vary!
…….Funny how the mind works.“Learning is limitless”

Yes they do vary slightly from manufacturer to manufacturer. But, you’re overthinking the issue, it rarely comes into play as every TV manufacturer knows that a portion of the screen is never supposed to be seen. Its more important to be concerned with this issue when outputting for the Web as that really is edge to edge…

David,
Actually I wasn’t “overthinking”, so much as stating how my mind was working.
Your previous posts pretty much answered everything, but like so much of this industry,
one consideration leads to another etc. (Even more so with the melding of the computer industry!).
I don’t know if it’s a blessing or a curse, but wondering what needs to be known
as opposed to what is known, requires a balance or nothing gets done.
Knowledge IS power, I suppose.

No sweat and no derision intended. Its just that I once had a client who obsessed about things such as title safe and action safe, and as they say, “a mind is a terrible thing to waste.” :}

Actually David,
I appreciate the responses.
I am old school, broadcast, theatre and film, in front, and behind the camera and I just when I think I know something, I get on forums like this one, and realize there’s so much more to understand and learn.
As I stated before, I often wonder what I don’t know, and wonder what I should know, and how much I should worry about what I don’t know, and so on and so forth.
It’s that balance thing again. Time management; gaining knowledge vs. making money.
Unfortunately, part of my responsibility is staying on top of things, to stay competitive and to keep my clients happy.
I’m sure it’s a common theme on these forums, but I didn’t start off in FCP, but another NLE.
A lot of money went down the toilet, and with it a pretty steep learning curve.
I just try and remember to laugh a little, mostly at myself.
Regards,

Keep in mind that nothing is “safe.” Action and Title safe boundaries indicate the areas within which most viewers are likely to see action and title content. It does not mean that material outside these boundaries will not be seen. My own rule has always been that, if it’s visible anywhere in the raster, somebody, somewhere will see it, whether it’s a boom mike at the top, the edge of a flat on the side or a cable on the floor at the bottom.
If there’s a great concern, then upsizing the image to eliminate a visible artifact is what you’ll need to do, knowing that doing so may cause overall image quality to take a hit. -
Chuck,
You were up early, typing that.
Just when I had moved on to OTHER THINGS.
