The more reports, the more Adobe knows it is a "large" problem, and the more chance of a fix

I have a similar problem:

Win7/64, Encore CS6.

Imported file: .h264 (encoded with MainConcept), CBR, 34.99Mbps. Length: 6min.

Preferences in Encore: BluRay, h264, CBR, max. 40Mbps, Main 4.1. (MainConcept Codec is shown on the display.)

- After import Encore want to transcode the file.

- "For fun" I let Encore do the transcoding procedure. It took one hour...

- The result: The "old" file (.h264) is 1.494.861 kb. The transcoded file (Encore made a m4v) is 1.494.966 kb. Why is the new file bigger than the old?

- Another attempt: I renamed the "old" file from ".h264" into "m4v". No cahnge to Encore - Encore wants to transcode as before.

Any ideas or solutions?

The project prefernce is "max. 40Mbps".

But the imported file - encoded by MainConcept before starting Encore using BluRay preferences Main 4.1 - is only 35 Mbps (CBR).

1. I don't understand that Encore wants to transcode the 35Mbps file.

2. I don't understand that the file after re-transcoding by Encore is bigger than before. I am wondering what Encore has changed in the file.

The bitrate viewer says,  in the source file the peak is 24.180 kbps (average 17.494 kbps)

and in the transcoded file by Encore the peak is 30.756 kbps (average 17.495 kbps).

The imported file is a only-video file .264. I had edited the whole video in my Avid Media Composer - I never have worked with Premiere - and then I exported the file and encoded it with the MainConcept Reference BluRay-Encoder (CBR, 35Mbps) to a .264 video and an .ac3 audio file. And finally I want to import these files to Encore to add chapters and compile a bluray... without any re-transcoding...

Yes, .264. Encoded from a Avid .mov with MainConcept AVCHD (BluRay compliant).

Well, in the advanced settings of MainConcept (Standalone) I could not rearly compare the settings with Jeffs infos of the BD-specifications, because I used CBR and not 2-pass-VBR.

Interested in the way how Encore decides if transcoding is necessary or not, I did several tries: I imported a 20sec-sequence, which I had first encoded with my MainConcept Ref.,  all with CBR, but with bitrates 35Mbps, 34Mbps, 33Mbps, 32Mbps, 31Mbps, 30Mbps.

The result of these tries is, that Encore wanted to transcode all these imported files - except the 30Mbps file: Here "Don't transcode" !

Therefore I think / conclude that the preferences in the MainConcept Ref., - which I had never changed -, are not the cause for the Encore limitation.

Hello, excuse me for perhaps a naive question, but what are the two principal reasons that serious professionals typically switch to the Main Concept standalone vs. the embedded one in AME?

Alternatively stated, are there a few key advantages to the standalone MC (as opposed to the embedded AME version) that attracts discriminating professionals?

Thanks, as always to both Ann and Jeff for being so INCREDIBLY helpful.

Thanks Jeff.... and lastly what are the two principal reasons that serious professionals might switch to MeGui?

Alternatively stated, are there a few key advantages to using MeGui that attracts discriminating professionals?

Thanks again.  We are so fortunate to have you here!

Thanks Jeff!  I guess there has been a small delay in releasing x264 for the Mac?  I was reading another thread that said that December 2012 was their target... Hmmmm.
