16:9 vs. 4:3 anamorphic
Could someone please explain to me what the difference (if any) is between 16:9 anamorphic and 4:3 anamorphic? Until this point I had never heard of two versions, just 16:9 with an anamorphic squeeze to fit into a 4:3 format. Am I just uneducated? The question arose while doing HD to DVCAM downconverts.
Thanks in advance,

Hi Sean
Both D5 and HDCam decks (setup #754 on the HDW-500) have setup selections for three SD outputs. One is letterbox, one is edge crop, and the third is anamorphic. The first two are common, while the third is used mostly for just making DVDs and not broadcast product. It takes a 16×9 image and squeezes the X axis down to 12×9 (4×3). Occasionally, by accident, our videographer has shot anamorphic. Using the dve I just expand the x axis to 1.33 and video is normal. DVD players do that on your TV.
I’ve never heard of a 4×3 anamorphic format, but that might be the way a person describes the above process. NTSC/CCIR 601 is 4×3 so other formats are converted to fit within its aspect.

Thanks Del, just wanted to confirm that I wasn’t crazy. I’ve always used the terms pretty much interchangeably, but it’s amazing how confident someone can be of something they clearly don’t understand.

Im curious; Is the term “16×9 Anamorphic” redundant? Isn’t 16×9 inherently anamorphic?
