Sample rate drop-down menu disappears / not shown

[secretsauce99]

Hey, I'm working with a cinema where I host album listening events in the dark (it's called Pitchblack Playback, check it out!). I supply them with albums as single-track stereo WAV files, with a bit depth and sample rate depending on what the highest available for the album is.

The Talk Talk album we're doing next is available as 24-bit, 96khz so I sent that and asked them to choose 96khz in the DCP->Audio tab Sample Rate settings. However, they don't have a Sample Rate section in their view. I've attached my view (red circles) and theirs. They updated to the latest version of DCP-o-matic. Same problem. What's going on??

The sample rate option is hidden by default as (so far as I am aware) 96kHz DCPs are rare, and may not play back properly. If you do make a 96kHz DCP I would check it out carefully in the cinema before the show!

To enable the option, go into the "non-standard" tab of preferences and tick "Allow creation of DCPs with 96kHz audio"

In most cases, choosing 96KHz is useless, because most servers or audio processors will perform downsampling to 48KHz anyway in order to keep a safe/konsistent processing chain. If you are in close contact to the operators of a specific screen, you may check beforehand wether a 96KHz DCP will work. Even if it works without issues, it's not said that server and audio processor will definitely feed through 96KHz (it's a config option in every server and cinema audio processor I know). Also, how much sense does 96KHz make in a standard cinema when the HF needs to pass through a PVC sheet with tiny holes in it? 24Bits, and uncompressed, is certainly more important in a cinema environment. If the album deserves it dynamic-wise.
