  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

In my feature film, I have few shots that require slow motion. If I were to shoot 3k for those shots how would that fair in uprezzing it to 4k to match the rest of the film?

I recommend you comform all to 2K. 4K is for great DOF.

2K will save you a ton in storage vs 4K.

We're doing a filmout for theatrical release.... so I'd like to retain 4k if at all possible. Is there any software out there that can do 3k natively, then all i need to do is just have 4k and 3k in the same timeline (which I just realized now).
 
Almost 97% of theatrical released feature films that are burnt back to film either via old print / kini / projection methods or via the newer DI transfers are all from 2k masters.
Hardly anyone does 4k unless its a giant VFX shot.
4k for most of us is total over kill at best, not saying its not worth shooting. After having 4k images its hard to go backwards, even if we are down converting to 2k in fcp. Down conversions have always been the way to go. You always get a sharper cleaner image going from big to small.

In short, save time, money, effort and grief, do your film project in 2k.
 
Honestly, if people are shooting 2K to save storage because 4K's ~30MB/s is just too much for their production... maybe they should be shooting DVX or HVX. Gentlemen, 30MB/s is chump change on a bad day.

Shoot 4K, shoot 3K for high speed, conform to either 4K or 2K depending on your budget and have a good shoot. Yes, 3K will match 4K as long as you make the necessary changes [use wider lenses to match FOV, open up a stop or so to match the DOF and add some mild sharpening in post to give it that extra punch].

I Think BigT didn't meant to shoot 2k but to finish into a 2k project.
Keep shooting 4k @ 30MB/s and have an output for film transfert in 2k dpx.

See you.

Shoot 3k for slow motion. 3k really is only using the center better part of the glass from my understanding, so up scaling to 4k shouldn't be that big of a problem. I haven't got to play around with 3k though, so I don't know for sure.

35mm projection in modern cinemas hardly resolve more than 720p. A 2K Di would do the job.

Hi Hans,

Last year I tested 35mm Arriscanner to 2K +4K & back to film, 4K was the clear winner whether sitting in the front, middle or back of the cinema. I had asked to see a direct contact print of the original negative, however that was not done for some strange reason.

Aha, then there is some kind of analogue oversampling happening. Oversampling is always good to have.

Doubtfull though on a low budget level to gain a lot by doing a 4K DI when the money could be invested much better elswhere.

Thanks for the insight,

Hans

DO NOT SHOOT 2K UNLESS YOU HAVE TO.

CONFORM 4K and 3K TO 2K.

There is only one exception, that is visual effects shots must be send to FX house in R3D and/or DPX at 4K or 3K.

4K will have focus mistakes that you can kinda cheat by conforming to 2K.

2K to film is the current standard.

Just remember 4K is 4x of 2K but your storage budget will multiply by 6x.

I am speaking from experience.

Not from what i've seen,
If your scanning 35mm film finish in 4K.
Shooting Red, downress and finish in 2K or 1080p.
At the moment Red is more of a 3K camera and less of a 4K camera,
if you know what I mean. This could improve in the future.
