Best Transcode settings for Blu-Ray from Apple ProRes?
on Jun 19, 2011 at 3:23:14 pm

I am shooting HDV, importing and editing in FCP ProRes. I would like to get the best possible quality out of my footage when transcoding to H264.

I had some problems with files I converted in Compressor, but was successful with Adobe Media Converter. But which of the presets is the best, and what changes are advisable to save your own "best" preset?

Should it be 1920x1080 or 1440x1080?

If I transcode in Encore, where does it store the transcoded files?

And do you have any more suggestions I didn't think of?

Sorry, but I am really just starting with HD.
Thank you for your patience and your support!

HDV nativ is 1440x1080, so you should encode it 1440x1080.

Thanks Daniel.
I am just a little bit confused.
After I rendered my stuff in FCP, I export it as a selfcontained Quicktime.mov
Looking at that .mov in the QT Inspector it says: Apple Pro Res 422, 1440 x 1080 (1888 x 1062) FSP 25 (which all makes sense) but then it also says Normal size 1920 x 1080, current size 1920 x 1080.
And because I couldn't find the files Encore transcoded for Blu-Ray, I transcoded the .mov files first in AMC before importing. There I wasn't sure what to choose and what to change (other than Audio which is PCM in AMC presets).

You seem to be highly experienced. How is your workflow for a BD out of FCP material?

Thank you for your help.
Chris

hey chris,
there are several ways to go.

this is one:

1.) export your selfcontained movie out of FCP using your sequenz-settings.
2.) transcode your MOV to blu-ray H264 and dolby AC-3. the best thing is to create your own preset.

you can create a generic AC-3-setting up to 640kbit/s, be sure your dialoge-normalisation is -31dbFs and that standard-film-compression is turned off to none on the 3rd. tab.

h264 is the best way to go - compressor only knows 1920x1080 or 720p for HD, there is no difference between 1920 or 1440 by 1080.

HDV is 1440x1080 and it will be decoded/played back at 1920x1080. quicktime is scaling the 1440 correctly to 1920 while playback, you have no influence on that.

but if you have an encoder where you can choose 1920 or 1440 by 1080 you better choose 1440 - otherwise you could get artefacts while encoding.

note: be sure to switch you audio-setting to dolby within your project preferences.

just my 2 cent.


cheers

Except Encore like Mpeg2 better than h264 in my experience when working with Blu-Ray.

wont agree with you Warren - haven´t seen any difference so far.

the main advantage of H264 vs MPEG2HD is you can create better picture-quality at lower bitrates, so you can put more content on your disc.

and adobe media encoder is using Mainconcept Encoder Engine that is also used with Sonic/Rovi Cinevision Encoder as well.

cheers
