Bluray

Como's back. back again
I have a 14 minute timeline, RED footage (5K) and I'd like to put this onto a Bluray.

How can I make an uncompressed file? Should I be using H.264 Bluray, or MPEG-2 Bluray?

Bitrate should also be under 20 correct?

Thanks,
Rob

Your requirements are 'inconsistent'... Both H.264 and Mpeg-2 as codecs are lossy compression codecs... The standard for Bluray is 1080x1920 as a 'maximum' spatial dimension. Bluray bit rate maximum is 40 Mbs/s

20 Mbs/s is the TV Broadcast 'standard' bit rate for HD.

On the other hand as a BD-ROM disk... you can put anything you want for archival purposes... but if you want it 'playable'... then H.264, Mpeg-2, or VC-1 are the 'standards', and of those, H.264 is becoming prdominant, and Mpeg-2 is receeding as a 'encoding codec'. (There's MPeg-2 as an encapsulation packaging... that's not going away so fast...).

Thanks for the reply.

It's for a festival, and they are asking for Bluray.

If you have 'Encore'... there are presets that AME has for outputing Bluray H.264. When using Encore, you should specify 'don't transcode' when importing to Encore, since you've already output the media in H.264 from Premiere via AME. Select a bit rate range between 20-30 Mbs/s, 1080x1920 size... I don't have Premiere and AME up right now, but something like level 5.1 or perhaps 4 or greater, will give you the 'quality'.

Also test the disk before sending it on several BD players if possible, or at least one... no matter what...

The other question is about Variable Bit Rate, vs Constant Bit Rate, and also 1 or 2 passes... Since I do 'short films' I can select Constant Bit Rate without generating too much data for the writeable device. I also select 1 pass... but perhaps 2 pass would be better for your.
