Re: [Avid-L2] BluRay one-offs

Jeff - what's the reasoning behind this?

I can use a Mac if need be, but have to use a Hackintosh to write to
BluRays.

You can burn Blu-ray on Mac without a problem. You just can't play it very
easily on a Mac. That's never been a problem for me, since I'm ALWAYS
checking my burned BD-Rs on actual Blu-ray players.

I use Compressor for one-offs. Super easy to drop on the automatic BD
encoding presets on and configure a Job Action to burn either a BD-R disc
image or burn straight to a BD-R burner.

One thing I would say is that grain is always going to be an issue with AVC
encoding for Blu-ray (or anything else). So much of your bit rate is going
to be spent on the encoder trying to get all those crazy pixels encoded
that the overall quality of the encode diminishes. It's tough on any
encoder to capture good quality grainy source. AVC (H.264) is your best bet
on Blu-ray as it offers the max bit rate you can fit on a BD-R. But for
grainy sources, I'd be inclined to go fancier and bring a KiPro Mini or
something that can playout ProRes or DNxHD. I know it's not in the budget,
just wanted to give you a heads up about the grain and how it factors into
quality loss with (relatively) low bit rate compression.
