When will 16:9 resolution be implemented?

[George Butterfield]

When can we shoot 4K 16:9 on the Epic?

 

[Dan Kanes]

4KHD is a 16:9 format.

You could always shoot 5K ff and extract the traditional 4K 16:9 that the R1 does.

 

[Steven Parker]

I second the question. Recently had issues extracting 5K 16x9 from 5K FF. A native 16x9 aspect at near 5K would be quite nice.

 

[Rob Ruffo]

Agree - 16-9 gives you almost exactly traditional academy, which is often useful - plus it's a lot easier to edit on a tight deadline.

 

[Pablo Villegas S.]

I second that! I will prefer shooting at 5K 16x9 than at 4K HD... But I can wait...

4KHD is a 16:9 format.

Thanks, I wasn't reading the latest Epic-X manual. Do you know what the aspect ratio of the 4K HD format is? I can't find anything that says that it is 16:9. What are the dimensions in pixels of the 4K HD format?

 

[Dan Kanes]

In the meantime, you can shoot 5K FF, and in redcine X apply the framing tool with the following settings:

fit Height
Lock Aspect ratio: 16:9

on output, select 1920x1080 (or whatever your desired 16:9 frame size is)

Cheers!

1920*2 x 1080*2 = 3840 x 2160

It is exactly 4 times as many pixels as 1920 x 1080. Easy math makes scaling the image much better.

HD is sharper than 16x9 and is better for TV as is a derivative of 1080p. 16x9 is better for filmout/ DCP.

Very hard to pick the difference though visually.

I was wondering because the RED ONE has a 4K HD resolution and a 4K 16:9 resolution.

What is the aspect ratio of the RED ONE 4K HD resolution?

Whereas the Epic-X only has a 4K HD resolution ..... I was wondering what the aspect ratio of the EPIC-X 4K HD resolution is.

 

[Jason Diamond]

You can also shoot 5KFF which is very close to 16x9 and do a minor crop.

It is...4KHD is 16:9
We shoot TVC's at 4KHD which is 3840 X 2160...perfect for TV and saves space on your SAN

On the R1 the 4K 16:9 setting uses 4096 pixels by 2304 vs the 3840 by 2160 of 4KHD. For TV finish I typically use the 4KHD option for the simple math scaling advantages. IF DCP or film out is the hero deliverable there are some advantages to 4K 16:9, though slight.

I concur that on the Epic a small crop from 5KFF to 16:9 aspect is the best quality option. It also preserves more sensor real estate which shortens DOF. Depending on your project, shooting 4KHD for 16:9 might be a smart choice - easier to hold focus, lower data rate (assuming the same compression ratio), narrows the lens FOV, faster transcodes (typically, not always), less potential for vignetting with some lenses and easier to integrate with native 1080 material.

Changing the crop of your sensor has no effect on your DOF unless you're using a different lens to match the field of view you had before cropping. Merely changing how much of the sensor you are capturing has no effect, in itself, on your depth of field.

"Traditional" Academy aperture (as in film gates) was 4:3. </pedantry>
