Blu-rays exporting at 720p instead of 1080p

So I've had this issue for quite a while and I just updated to FCP 10.3 hoping that it would go away, but alas the issue remains. I have a project that is made up of entirely 1920x1080p clips shot at 59.94p. I verified this in the project settings. But when I go to export a blu-ray, it says that it is exporting at 1280x720 and doesn't give me the option to change it to 1920x1080.

Has anyone else experienced this? All of the research I've done says to change your project settings, but like I said, they are correct.

If anyone has a fix, I'd appreciate it!

Blu-ray unfortunately doesn't support 59.94p in its specification, only 59.94i or 29.97 at that frame resolution.

Ah, well that would explain my mystery. Thanks for the info!

Do you know if there are any drawbacks to switching my frame rate from 59.94p to 59.94i on my camera? I'm not really sure what the real-life difference (visually speaking) is between progressive and interlace.

Interlacing looks horrible when viewed on a computer screen. I personally loathe it and would rather do 720p59.94.

I shoot mostly weddings and have always done 60p because of the nice slow motion with the higher frame rate. I think I’ll just stick with what I’m doing and export the blu-rays at 720p @ 59.94p. The results don’t look bad, it was just more of a curiosity than anything else.

I wouldn't do it in the camera. I'd keep the 1080p 60 file around, but for the Blu-ray I'd encode a 1080i version. Most players will play this well and you won't see any combing artifacts. However if you were to play the 1080i file in, say, Quicktime Player on your computer, you WOULD see the combing artifacts. But at least this way you can get the temporal resolution with a minor hit to the frame resolution by encoding in 1080i for the disc. The 1080p 60 version can be uploaded to Youtube or whatever and enjoyed that way there. Or maybe when the inevitable UHD Blu-ray authoring app becomes available... LOL I kid, that'll never happen.
