Quick update, this is from last year's submission rules, para 31.

http://www.sundance.org/pdf/submissi...ssions_FAQ.pdf

31) If my film is selected for the Festival, what exhibition formats do you accept?
We accept DCP, and 35mm film prints for exhibition at the Festival. Feature films delivered on DCP must include two copies on CRU drives and a non DCP backup. All DCPs must be DCI compliant with drives formatted with EXT 2 or 3 file systems (single partition,master boot record). All encrypted DCPs must supply DKDM keys that remain open for the duration of the festival. Bluray or ProRes file backup copies must be provided for both shorts and features on DCP. For 35mm film prints, we screen 24fps in aspect ratios of 1.37, 1.66, 1.85, or 2.39. We accept sound formats of mono, Dolby SR and Dolby SRD (Dolby Digital). Please note that these specifications are subject to change at any time. If your film is accepted into the Festival, we will provide you with the most up to date exhibition specs and deadlines for delivery of your master at that time.

Thank you for your reply. I have read the faq. The things
which I confused is the conversion of dcp. For instance, if I have a 1920x1080 24p mp4 file. Can dcp conversion qualify this file to 2.40:1 cinema? 1920x1080 is only 1.78:1.

The DCI spec allows for 16:9 aspect, despite not being specifically defined. If you conformed 1.78:1 to 2.40:1 you could either have a squashed or cropped frame. You'd be better off slightly cropping to 1.85:1, but your best bet would be to use the full 16:9 frame.

Thank you for your words. I have read many indie film festival's FAQ, and they said DCP is for exhibition. But if we broadcast 1920*1080 files in DCP without adjustment , then there will have some blank on the screen. Like this.

However, for many indie film maker, they only can use digital camera for their film, and most of them can only make 1920*1080 files. I wish the film festival won't mind the blank on the silverscreen.

If you plan to exhibit in a given aspect ratio, shoot in that aspect ratio. Sure, the camera sensor will capture 1920X1080 pixels, but you don't put anything you want to keep in post in the areas that will be cropped out in post. You can get an aspect mask to put on your viewfinder/monitor if you don't have the ability to show crop lines in camera/monitor. If all else fails, you can use Scotch tape to mask the "safe zone."

It really depends on the viewing theatre and how it's set up.
Your options are to use a 16:9 spec in the DCP or crop to a notebook traditional aspect.

Next time shoot 1.85:1

Thank you for your words. But I still have one last question. I have read an article said Moondog Labs 1.33x Anamorphic Adapter for iPhone 5s can make 2.40:1 aspect ratio from the original 16:9 for DCP. As far as I know, even though you used adapter, you still can not change the original source. The video which made by Iphone is still 1920*1080. Why can Moondog Labs change it?
