2:1?

[Rich Schaefer]

So, I am just figuring out my new camera here. I can't find an explanation in the manual (online) or searching the forum, for what 4k 2:1 & 2k 2:1 are?

what is 2:1? Anamorphic?

Also: Can the camera do a 4k project @ 29.97? Mine doesn't show me the option.

Thanks Much,
Rich


I am sure I will have more stupid questions to follow.

2:1 just means that you have the option of shooting an image that is 2x1 or 16x9 in shape -- it's not anamorphic. I think in 4K RAW mode, a 2x1 frame is 4096 x 2048, rather than 4096 x 2304 for 16x9.

The first batch of cameras were limited by software to 2x1 images but I think 16x9 is now enabled, or soon to be. Same goes for shooting 4K at 30 fps (and I assume 29.97 fps) -- if it's not yet enabled, it will eventually unless I am mistaken.

Their may still be some limitations on using 16x9 on the post end, I haven't kept up. Check the release history for RedAlert, Redcine, or the QT codec before you mount up a big project in 16x9.

Hi David, Thank You Sir!

My camera #115 will do 4k2:1 @29.97, but not regular 4k @29.97. But that makes sense if the 2:1 difference is just a few hundred pixles.

Other thoughts?

4K 2:1 is still the workhorse. Hard to go wrong with that unless you are truly finishing to 4K. And you want those extra pixels.

Quicktime and RedAlert don't currently like the 16:9 4k format. Redcine likes everything though. 16:9 functionality will come to future QT and RA though.

We did some last minute 2nd unit shots for JUMPER on a beta of Build 12 in 4K (16 x 9) - works great in REDCINE - the VFX guys want all the screen real-estate they can get -

we did both our features in 4K 2:1 - but I think our next will be 4K (16 x 9) pending some downsample tests -

[Brook Willard]

Most [if not all] of the work we've done has been in 2:1... if for no reason other than the Red Alert!, Quicktime and FCP compatibility. I'll shoot 16:9 all the time when it's "fully" enabled across the board, but for now... 2:1 is the safest bet for me.

[Rich Schaefer]

Thanks for the info guys!

[Rich Schaefer]

OK, New twist. When I set the project to 4k2:1 @29.97 no varispeed, the camera gives me a "Recording Error - FrmRate_TooHigh"

any ideas? am I setting it up wrong?

[Radoslav Karapetkov]

Isn't Vittorio Storaro recommending the 2:1 aspect ratio as being the best balance between all the available options? I mean, not only on the RED, but - in general :).

I wonder if He knows of the RED camera yet?

[Stuart English]

Thanks for that feedback.

Thats appears to be a new bug related to how RED-DRIVE v's CF card support different frame rates and resolutions.

We'll fix it.

[roryhinds]

4k 16:9 QT support is much needed and I hope just around the corner as 2.1 is a post pain.

[Rob Lohman]

16:9 will be available in the rest of the post apps very soon, working on that today

Hope you're not writing code with a hangover... that could result in some interesting features.:sick:

[Rich Schaefer]

Stuart, how do we get the fix once it is done? The next build or sooner?

Thank You!

What are you filming at 29.97? Just curious.

[Rich Schaefer]

Yes, 29.97, I shoot mostly commercials. Many of which are shot @ 29.97 like cars & product shots.... So, I am anxious to get 29.97 enabled.

shoot 23.98 and add the pulldown in post -

[Rich Schaefer]

Thanks Mark, adding the pulldown is easy, but it adds stutter especially on product shots....

So much good info on this here website. I'm going to try that out immediately.
