Xf 50Mbs CBR to Blu-ray

Could someone describe their work-flow for taking the 50 Mbs CBR MPEG-2 video from either the XF-100 or XF-300 and recording it onto a Blu-ray disc. I believe that the maximum video bitrate for Blu-ray is 40 Mbs, so some processing must be needed (not that most people would go direct to Blu-ray without editing anyway).

Hey Mark,

The process is no different than any other camera. Shoot, transfer to computer, edit, export as mpeg-2, author & burn to BD.

Are you looking for something more specific?

Hi Tim - when you export as MPEG-2, what bit rate settings do you use for best quality ? I've done all my work with Panasonic and P2 cards, with Edius 6 as a NLE, but am considering a switch to the XF-300.

Hello Mark,

I use Edius as well. The workflow is the same with any camera, P2, MXF, AVCHD. The Blu-ray output settings are based upon how long your project is. The settings are as high of a bitrate that will allow your project to fit on a disc.

My reading has turned up that the Blu-ray spec is actually up to 48mbps but the discs are limited to 40mbps total bitrate. This is good as you can make a disc all the way up to 40mbps and still have 8mbps of headroom per the spec for playback.

You might want to visit the Edius forum here or the official Edius forum for Edius questions.

You can use either MPEG4 or MPEG2 as the CODEC when recording to Blu-ray. 40Mbps MPEG4 will be much higher quality than 40Mbps MPEG2 (which will still be very, very good).
