File formats and/or codecs, w/r/t burning files onto blu ray

What file formats and/or codecs are optimal during the rendering process if you want to burn those files onto blu-ray discs?

On Mac OSX, we usually render to ProRes 422HQ, and then use something like Toast to make the Blu-ray. In truth, for us in the last 10 years, discs have pretty much gone away and we do everything as digital files. Blu-rays are extremely rare.

If we're dealing with a Blu-ray factory, we send them whatever file they want, formatted the way they want it, and let them author and compress it for release.

I'm not sure Resolve can export files directly usable for BD authoring. At least not on the video front. Which means you'd have to transcode anything exported anyway.

So make it the best possible quality file your BD authoring tool can accept.
