H.264 Blu-Ray and Encore
forgive me as i’m not a regular poster to the Encore forum, and if this question has already been answered. i did a quick search and couldn’t find anything, which might mean its no longer a problem.
i’m currently using Encore, along with Compressor and Toast 10 to make MPEG-2 Blu-Ray discs. i know that Encore can also make H.264 discs, but in a few different How-To’s that i read, it says that Encore will take an H.264 file and transcode it to MPEG-2. and you can’t tell it not to. is it true that it does this? i’m thinking about getting the Matrox CompressHD card to make Blu-Ray H.264 files, but i want to make sure that Encore will play nice with them.
on a similar note, how does a H.264 Blu-Ray compare in quality to a MPEG-2 one at similar bitrates? i have noticed that most Blu-Ray titles are MPEG-2, but there are a few like one of the Pirates of the Caribbean movies, that are H.264, sometimes going over 40Mbps! i don’t think thats possible with MPEG-2.
thanks

Not true, Encore transcodes to H.264 directly without transcoding to MPEG-2 at all.
EDIT: Encore will also pass through H.264 files that are Blu-ray legal without re-transcoding.

thanks. i wonder if Encore thought that the H.264 files weren’t legal for some reason. i have CS3, btw. maybe the authors of the How-To’s were on older versions.
i’m going to rent the Pirates sequels to see for myself, but i read somewhere that when you turn on the Display on a Sony Blu-Ray player and it lists the current codec and bitrate, that at times the movie was going over 40.
thanks

Also, the maximum video bit rate for Blu-ray is 40 Mbps.
-
Total video and audio bit rate can’t exceed 48 Mbps, but video bit rate is limited to 40 Mbps.

I believe CS3 will transcode your blu-ray motion menus to MPEG2 regardless of which format you specify (if I recall correctly). CS4 will create h264 menus while in H264 authoring mode, however it will most likely spit out an error message during the build process.
You should specify MPEG2 as the authoring mode regardless of what you want your video to be. You can then set the transcode settings of your main video to H.264 for better quality. If you have already created the h264 file using the CompressHD in Premiere, just import that into Encore and it won’t need any transcoding (even if your authoring mode is MPEG2). Encore does support burning h264 to blu-ray and it works well (I’ve done it many times).

Sorry buts thats not true. On MAC, Encore dont work with CompressHD h.264 file. Crash all the time.
From Matrox Forum
“Adobe Encore CS4 has stability issues when burning 1080i material created with the Matrox MAX H.264 codec to Blu-ray Disc. To burn 1080i material to Blu-ray Disc, you can use an alternate application such as Roxio Toast. (Ref# 50554)”
We apologize for any inconvenience and hope to have a fix for this in the near future.This is the link for this thread

I hope they fix that. ADOBE our MATROX

That has not been my experience on the Mac – I can work with h.264-encoded files from Premiere, Adobe Media Encoder, and Apple Compressor without stability problems.
Sounds like your problems may be hardware (Matrox)-specific?

Ok so tell me please, what Level you use and BitRates when you export with CompresHD Presets ???

Sorry i was talking about H.264 file encoded with CompressHD card.
With Adobe Media Encoder works good, buts takes forever.

Maybe so…but it doesn’t crash.
