letterbox stretching aspect ratio dvx100a help!!!

I shot video on my dvx100a camera in letterbox mode. My manual says letterbox means 16:9.
In FCP I captured using easy set-up NTSC and 48KHZ 720x480.
Maybe that is wrong?
Anyway I noticed the image looks stretched in the viewer. If I uncheck anamorphic in all my clips the image looks normal. But when I export video edited this way to FCSP or just to quicktime I have black bars not only on the top and bottom but also on the sides. It's not terrible but the image is a box within a black box or - how do you say? floating on black.
Is there something I'm doing wrong? I tried capturing with 48 KHZ anamorphic and got the same thing.

Anything I can do? And if there is something I can do, does that mean I need to recapture all my video using a different capture setting?

I own the DVX100B, essentially same camera. In Letterbox mode, those black bands are already burned into the 4:3 frame. The manual states "Black bands are recorded at the top and bottom of the image."

Therefore, I would guess you should capture as ordinary NTSC 48K. Then you can scale the image up into a 16:9 sequence if you want but it will degrade the picture accordingly. But at least your aspect ratio won't change.

The Panasonic DVX100A/B is a great camera but you should not film using Letterbox mode. You could try the Squeeze mode, but the best method for getting 16:9 from the DVX100 is buying an $800 Anamorphic lens adapter. I outfitted both my cameras with one. This allows you to use FCP's NTSC 48k Anamorphic capture preset to get the best 16:9 from that camera. But if you must have wide screen, try the Squeeze Mode. Good luck.

Hope that helps.

Hey thanks. It's accidentally set to letterbox and now I have to finish the project that way.
The only thing that bothers me is that I have to uncheck anamorphic to get the image to look right and then there are black bars on the sides also. Essentially it's a box within a black box.
It looks OK but I'd rather only have the bars on the top and bottom - not on the sides!

I don't agree with audioamigo with his opinion that "letterbox" is a bad mode to film in on the DVX100A or B. It's simply a different way--it really depends on your delivery. Letterbox on the dvx100 is actually 4x3 footage. The camera literally just shuts off the pixels for that area of sensor to simulate widescreen on a 4:3 image. In other words, it's not true 16x9. Squeeze mode gives you 16x9, but the image is scaled up to "squeeze" into it, so there's some image quality lost. An anamorphic adaptor is needed for true 16x9 footage at the best quality on the dvx100a or b.

It's 24p letterbox.
I kind of understand - I'm getting to the point of understanding what you guys are saying.
But there is still something perplexing:
When the clips are loaded in the way I'm capturing them they look squeezed because FCP has them checked as anamorphic. When I uncheck it they look fine.
But then, when they are ultimately exported to quicktime or anything - the image is in a black box.
It looks ok. But it's not simply a letterbox (top and bottom bands) the sides have black also so the whole thing is a box within a black box.
It's not necessarily bad, but does it have to be this way?
Do you guys get my question?
Sorry I'm a bit of a dolt with this stuff.
I appreciate all your time to answer my questions.
Thanks so much

Sorry Jim. I missed that.They are NTSC DV3:2, dv 720 480

Anyway, when I put something into sequence it asks if I want to match it and I click yes.

You see I think here is maybe the problem (and I know I don't know as much as you guys and other so I can be wrong): I think even though the manual for dvx100a says letterbox is 16:9 - that in reality it is not and so to have the video look un stretched it adds pillarbox?

Aug 19, 2010 4:28 AM in response to Jim Cookman

Does what I said make any sense? I think I made a big mistake by shooting in letterbox. But it depresses me to ruminate on that.
I tried capturing in different ways but no matter what it looks stretched until I uncheck anamorphic.
Then exporting looks stretched unless I uncheck anamorphic in which case it adds the (is it pillaring? black on all sides?)
I'm such a dolt I shot two movies before like this and didn't realize it was a problem. No one even commented on that (so on the good side maybe it doesn't matter?)
My last movies look great projected because you don't see the pillarbox. But on a screen I don't like it.
Maybe there is nothing can do?

Aug 19, 2010 4:41 AM in response to Jim Cookman

Yeah Jim. I don't think that's the problem. I'm so grateful to people like you who take the time to help with these things.
I think the problem may be that my camera doesn't record on true 16:9 but adds a letter box to 4:3 and so if it's set to anamorphic it's stretched and if it's set to 4:3 it adds a matte?
mayyyyyybeeeee?

Aug 19, 2010 4:49 AM in response to Jim Cookman

but the manual does say it's 16:9 in which case I don't understand.
Is there something else I'm missing or do I accept the Matte/pillarbox as my reality and move on.

As far as I can see the settings are all for dv and not hd.

anyway thanks!
it's not a big problem.
I wonder if a "no budget" film festival will reject something because of the matte/pillar look...
question for a different forum!

You should not have any pillarboxing. It seems pretty clear that what you have is DV NTSC with black recorded on the top and bottom of part of the image. I believe "squeeze" mode is the way to record anamorphic 16:9 on the DVX-100a. But forget anything else. It doesn't matter that you have those bars on the top and bottom. As far as FCP is concerned those bars could be filled with pictures of kittens. Uncheck "anamorphic" on all of your master clips in the browser. If you've already done a lot of editing, *make a duplicate of your sequence*, then make sure Anamorphic 16:9 is also unchecked in your sequence settings, then select all clips in the sequence (⌘+A) and then hit ⌘optionv to bring up the "Remove Attributes" window. Check "Basic Motion" and "Distort." This should remove any pillarboxing or distortion from your exports.

OK. I understand completely now. And I feel bad about taking anyone's time on this. Thanks so much.

This is my problem: I shot in letterbox! Bad idea!
When exporting, clips/sequences look fine.
But in Fullscreen it has to add black around the sides. It's the nature of letterbox. It's just a sizing issue.
If I hadn't shot in letterbox it would look more normal.
It's just fitting the image to a bigger screen.
It's juts simple. The only way to change it is to blow the image up which would distort it.

I think all the capture settings are fine. It's just the nature of letterbox.
It's an issue of projecting after it's been exported - not an issue with anything else.

I'll look into this Kyle but I think I left out some important information.
there is only black added to the sides in fullscreen. Otherwise it's normal.
I'm told that this means the issue has to do with playback and this may be normal for the sizing of the format I hot in.
In non-fullscreen normal size, or in the viewer or canvas there is only black on the top and bottom.

It's just when one looks at it in quicktime in fullscreen mode that black is added so the movie can fit without being distorted.
I'm thinking there is nothing that can be done.
