Anamorphic with 2.21:1 with 1920x868 resolution?

[Emin Henri Mahrt]

Hi,

 

i am a bit confused. I bought a "16:9 widescreen lens" glass and everything looks anamorphic, picture is stretched too. After playing around with the footage and VLC i recognised, that my footage with (i've used the Anamorphic LPowell Flowmotion Hack) 1920x810 looks stretched here an example:

A few days later i checkt on a "square note" paper and saw, that the image is streched. I endet up with 2.21:1 with 1920x868 resolution. Is that right or am i doing something wrong?

Thank you and best regards

you can film a circle (it will appear as an oval on your camera), then stretched the image to have a circle.

Which lens is it?

@Farges, i did it with a square note paper and eded up at 2.21:1 but i think thats "not normal" too. Can it be?

Try different focus distances.

 

From the footage you're showing here the 2:21:1 aspect looks correct. That would make it 1,25x instead of 1,33x.

Sometimes focus "breathing" (i.e. shifting field of view when changing focus) can give you an odd aspect ratio. For instance, my Lomos are more like 2x focused to infinity, but more like 1.8x at close focus. If you were focused at 11.5 feet (for example), the correct aspect ratio would lie somewhere between the extremes and would not be a standard stretch factor.

I'm no expert but I have a feeling the lens itself is supposed to work with a 4:3 sensor. Since you're using it on a 16:9 sensor I assume, you're getting a weirder stretch than normal due to whatever conversion rate that would be...
