1. Re: Does Encore degrade the native file during DVD authoring?(PPro related)
John T Smith Jan 24, 2014 2:31 PM (in response to bboyatomik)You are wasting your time exporting as BluRay and then having Encore create a DVD... which requires a SECOND transcoding step
Export MPEG2-DVD from PPro and use the 2 (audio and video) files to author in Encore... if you have all your MPEG2-DVD settings correct, Encore will show the assets as not needing to be transcoded again to create the DVD

2. Re: Does Encore degrade the native file during DVD authoring?(PPro related)
RjL190365 Jan 24, 2014 3:21 PM (in response to bboyatomik)Here's the problem:
Encore cannot author high-definition content onto DVD at all. And once you set your Encore project to output to DVD, the video will get re-encoded and downconverted to standard definition (480i) no matter what. Unfortunately, there is no way around that without outputting as a Blu-ray folder, then using a separate burning program such as IMGBurn to burn onto DVD (since Adobe will not support HD content creation onto DVD at all).
And yes, the encoders in Encore will degrade the file during DVD authoring if re-encoding the file is required.
By the way, that 25-minute, 5GB file is encoded at too high of a bitrate for HD content burnt onto DVD at any rate. HD material burnt onto DVD is limited to a maximum total bitrate (this includes video, audio, menus and miscellaneous tracks combined) of only 18 Mbps. Unfortunately, your MPEG-2 HD file is encoded at 25 Mbps, which is way too high for DVD to handle.
Hope this helps.

I'd like a bit more detailed info as to the process you suggest ... being such a noob to transcoders, decoder rings & the like ... sigh.

RjL190365 Jan 24, 2014 4:41 PM (in response to R Neil Haugen)Neil,
To export in Premiere to an "AVCHD" DVD, export from Premiere using the H.264 Blu-ray template, but setting the encoding to CBR and the video bitrate to around 15 Mbps (the default encoding for that template is set to 1-pass VBR, the average bitrate to 25 Mbps and the maximum bitrate to 30 Mbps). Then, go to the Audio tab and select Dolby Digital instead of the default PCM (unfortunately, Premiere Pro CS6 supports only 128kbps stereo for the output when selecting Dolby Digital in a Blu-ray preset).
When the export is completed, import the just-encoded .m4v and .ac3 files into Premiere, then output as a Blu-ray folder rather than directly onto disc (since Encore cannot author HD video directly onto anything smaller than 25GB without re-encoding and downconverting to standard definition MPEG-2).
Finally, if you do not know what IMGBurn is, it's a freeware program that you can download from the IMGBurn Web site. Once you installed IMGBurn, you may choose to create an image file from folders or burn disc from files/folders.
When all that work is done, the result would be an "AVCHD" DVD that's only compatible with Blu-ray players (but might not be playable on every player without pauses and/or stutters/skips). A regular DVD player cannot play back such HD discs at all.

I guess I did waste some time, I had no idea DVDs are limited to 480i or 720p.
So anyway, what I'm going to do is export my HD film on PPro as Mpeg2 1080p with Dolby sound and then import it in Encore. The question is do I select Automatic during the settings before I build a DVD?

John T Smith Jan 27, 2014 8:23 AM (in response to bboyatomik)You are going to have lower quality due to encoding TWICE... from PPro as "Mpeg2 1080p" and then again in Encore to MPEG2-DVD to make "legal" assets for a DVD project
Export from PPro as MPEG2-DVD and use the 2 (audio and video) files for your Encore project

bboyatomik Jan 27, 2014 9:16 AM (in response to John T Smith)So once I import the Mpeg2 Dvd & Audio file into Encore, do I select "Automatic" in the settings list before I select Build?
thanks again John about reafirming the correct PPro export.

John T Smith Jan 27, 2014 9:23 AM (in response to bboyatomik)As long as you keep your MPEG2-DVD export within parameters that are "legal" for a DVD, the assets will show in Encore as "do not transcode" and you don't have to worry about your Encore transcode setting
The only time Encore will want to RE-transcode is if the asset is not legal for a DVD... such as if you change a PPro export setting to too high a bitrate

bboyatomik Jan 27, 2014 6:09 PM (in response to John T Smith)Cool links,
Just had a smooth No Transcoding build, you definitely know what your talking about!
Its getting clear to me now. So back to the PPro export, a higher MB/GIG file doesn't really mean better quality? Especially since the Video and Audio file together (1080p mpeg2 - dvd) was 900mb versus the previous (1080p mpeg2- dvd) 3 gig file, especially once its on DVD right?

John T Smith Jan 27, 2014 9:08 PM (in response to bboyatomik)It's been awhile since I tried to change any of the default settings, but as I remember (not always 100%) the maximum bitrate is 9000 for both video and audio, so if you (I think!!!) have your video bitrate at 8500 maximum you have room left for the audio
Experiment and watch the transcode status in Encore, and how the resulting DVD looks
