Apple’s Compressor MPEG-2 settings.
Step-by-Step instructions for using Apple’s Compressor v3.0 to
create Mpeg-2 stream and burn Blu-ray disc using Encore CS3.
Background Info on MPEG-2 Streams.
Types of MPEG-2 stream:
There are three common Mpeg-2 stream types that are used to deliver MPEG-2 encoded video in Compressor(v3.02) :
• Elementary streams: These streams contain only one Mpeg-2 content and no audio.
• Transport streams: These streams can contain several Mpeg-2 content channels and associated audio.
• Program streams: These streams contain only one Mpeg-2 content channel and its associated audio.
By default, the Compressor Mpeg-2 encoder creates elementary streams. You have to configure the Mpeg-2 encoder to Program streams to create Mpeg-2 files for Blu-ray.
We did a straight FCP export to .mov file and dropped into Toast 9 with bd plug in, burning to BD-RE. Set it for autoplay – no menu. Got an error at the end of burn, but tried playing the blu ray anyway to see if we were on track. It played, but was choppy. I saw one could burn the bdrm (sorry if I used the wrong folder name) folder in toast, so we’ll try a compressor conversion with the settings above and drop that into toast. Just trying the options to see what works the best.
