Trying to decide between 1080p and 2K

I am trying to decide between 1080p and 2K. I feel 1080p should be large enough, but just not sure what it will look like projected. Anyone have any experience projecting work done on Anime? Thanks.

2048 x 1100px (1:1,66) (2k on Super35mm)
1920 x 1080px (16:9)

The difference of 58 / 20px can be neglected. HDTV is as good for recording on 35mm as is 2K.

I'd say the difference is pretty negligible.
In live action you'd try to get as much resolution as possible to combat grain and stuff but with animation you have a pretty much perfect image right from the start.

For a relative size comparison, black is 2K, white is HD:

Thanks for breaking it down and laying it out guys - I also take the point that a drawn image is arguably more robust!

1080p is enough for 35mm transfer, there shouldn't be any visible difference as pointed out before. (I've done a few, both from 2K and 1080p and speak from experience)

For TV/blueray etc. where the display format is 1920x1080 it is better to work in this resolution to start with. Otherwise you either have to crop your images to fit or scale them down. Scaling this small amount will give you strange results with degraded line quality and such.

Use 1080p, it's standard nowadays for all kinds of output, including film transfer.

2K is useful as output for S3D HDTV.

Basically, a shot is framed for HDTV but rendered with over-scan at 2K. This permits around 6% of lateral and vertical adjustment in post-production for aligning the depth settings from one shot to another. Its the primary technique for S3D with RED ONE cameras.

Be careful too, 2K defaults to 24fps progressive, HDTV to 25 or 30, progressive or interlace.

Unlike HDTV, 2K is not restricted to frame rates or ratios. Around 90%+ digital cinema projectors worldwide use 2K (24 or 48fps). Some are now 4K (24fps). If you want to screen in a cinema then 2K is the route to go.

i am referring to digital projection, not dumping onto 35

definitely progressive, probably 24 or 25

But what format would the movie end up on? Disc, blu ray, video?

Well, it would 'end up' on various formats I guess.

But I am particularly concerned with digital projection right now - wondering if 1080p will be inferior to 2k.

I am inclined to think it won't, but not 100% sure.

It will not. You can't see any difference with the naked eye.
