Exporting 220 Mbps Apple ProRes 422 HQ?

Hey guys,

My latest film was accepted in several film festivals and one of them requires it to be sent in Apple ProRes 422 HQ at 220 Mbps. When I select the Apple ProRes 422 HQ export option in Premiere I don't see anywhere the option to select 220 Mbps. There has to be a way to do this.
 
Congratulations! I'm not sure you can set a different bitrate for that flavor of ProRes because I think the bitrate is fixed. Are you delivering in HD? The Apple literature online says about ProRes 422 HQ: "The target data rate is approximately 220 Mbps at 1920x1080 and 29.97 fps." So that would make sense to me that they request that bitrate, although it should be slightly smaller for 23.98 fps (176 Mbps) and 4x larger for 4K (884 Mbps). So, I think you should just select ProRes 422 HQ and not worry about the bitrate part.

Use Media Encoder and set a constant bitrate manually.

[Apple's Compressor offers the functionality, so I'm assuming ME does too.]

The sometimes comical essence about these kind of requests over the years was that some accepted films (especially at less well-known festivals) shot twice as low as their playback target "requirement". The old-school thinking was that a higher data rate would playback the lower data rate footage better.

I guess a similar compression ideology to some people uploading their 4K videos in 8K on YouTube these days.
 
I suppose the question is if they definitely want ProRes 422 HQ or if they definitely want 220Mbps. ProRes HQ setting dictates the bitrate based on resolution and framerate. 220Mbps only equates to ProRes HQ at 1080p 30fps. You may need to ask them, but my guess is that they want Prores 422 HQ regardless of exact bitrate, since ProRes 422 HQ dictates quality. 220Mbps for a 4K video will be well below ProRes 422 HQ quality.
 
Yea, that would be helpful to know...but they could have both assuming any 4K footage is just delivered in 1080p (which I'm assuming is the case).

And most of the time if anyone is asking for High-Definition ProRes HQ 220Mbps, it's understood it will be a bit lower like you mentioned for the lower framerates of 24p or 25p opposed to 30p (which I'm assuming no one is using to shoot their film).
