FCP 7 not exporting 16:9 properly

[Mark Maness]

[Joey Burnham] “Elaborate please.
Is not anamorphic just widescreen picture squeezed 33% horizontally to fit in a 486 frame size? Ignore HD for the time being.”

To answer your question, yes. In video, we normally refer anamorphic as a 16:9 frame in 4:3 video space, otherwise known as letterbox or widescreen.

The discussion we are in is about 1440×1080 and 960×720 being called anamorphic, which they are not.

In order to HDV, XDCAM HD (not XDCAM SD) and DVCProHD to work as they do, they use a method of pixel scaling to cram as much info into the smallest amount of space to maximize tape or disc and also, the manufacturers can use lesser quality chips to get similar results of full raster chips. I didn’t say they got the same results, they just get similar results, meaning HD video from a smaller CCD or CMOS chip.

Like I said, pixel scaling is referred to video sizing like 1440×1080 and 960×720 only, everything else is using the term anamorphic.

Technically it’s not right to use the term anamorphic for standard definition video either. Technically anamorphic refers solely to a lens distortion and projection system to squeeze a widescreen image into a standard Academy frame. The term anamorphic format refers to any electronically squeezed widescreen format into a smaller frame. In standard definition the widescreen and the 4:3 frames are coincidentally the same frame resolution. In HD of course there is no 4:3 frame resolution so any HD format that does not use a full raster frame size can be considered an anamorphic format, and gods know there are plenty of them, and the way we’re going probably even more coming down the road.

All the best,

[walter biscardi] “HDV, HDCAM and DVCPro HD all shoot 1440×1080.”

DVCPro HD is 1280×1080 in NTSC areas and 1440×1080 in PAL areas, IIRC.

As I understand, Anamorphic implies applying a “distortion” on acquisition and the opposite distortion on screening. This is done electronically (underscan) or optically
We do it to put a frame with a certain shape in a captor with a different shape, or to scan only part of the target..

HDV and DVCProHD, don’t use this method. They scan the full CCD/CMOS that is made with a proprietary pixels aspect.

Everyone is right to a point and yes, FCP lists this as anamorphic. But let me add to this… The reason camera engineers and AJA call it pixel scaling is because the term anamorphic refers to a method of projecting an image whereas in digital cameras, the actual pixels on the chips, be it CMOS or CCD, are in non-square pixels patterns to maximize the chip area.

I say all of this because my background in broadcast TV is in engineering. So this technological discussion really fascinate me.

Hey Gary… Chime in at any time…

I think we need Gary less than we need a lexicographer.
