Stan Jones Jan 7, 2012 3:50 PM (in response to JSS1138)If you are not looking at the wrong info, this may be a bug related to 2 pass vbr H264.

See post 20 here, where Jeff (I think) is suggesting that this may not be a single 2 pass vbr bug, but a relationship between the profile also.

HarpuaFSB Jan 7, 2012 5:40 PM (in response to Stan Jones)Definitely looking at Blu-ray info, not DVD and almost positive it's the VBR 2-Pass H.264 bug discussed elsewhere. Encoded using VBR 1-Pass and Encore accepts the clip no problem.
Also heard that this has been a bug since CS4? That's crazy.

13. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
nordental Feb 9, 2013 12:33 AM (in response to HarpuaFSB)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?

14. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Stan Jones Feb 9, 2013 5:08 AM (in response to nordental)While your problem fits the general topic of this thread, it is otherwise different. The H264 2 pass bug was fixed with CS6 (it was CS6 and not an update, right?). Also, you are exporting CBR.
You have a project max of 40Mbps (which is video and audio combined), with CBR fairly high. Any spikes and your file will not be compliant.
Does anyone have a better bitrate viewer than "Bitrate Viewer"?
-
15. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
nordental Feb 9, 2013 8:19 AM (in response to Stan Jones)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 it exported as H.264 which generally gives mp4 or as H.264 BluRay which will give you m4v with multiplexer off (prefered) or m2t?
If its mp4 it gets re-encoded.
Max bitrate for BD vbr or cbr is 35.
Make a screendump of your export settings in Premiere.

17. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
nordental Feb 9, 2013 12:46 PM (in response to Ann Bens)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...

18. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Ann Bens Feb 9, 2013 1:54 PM (in response to nordental)Somehow your Avid does not make a BD compliant file to have Encore not re-encode.
.264 it that the extention for the videofile?

20. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)

21. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Jeff Bellune Feb 9, 2013 2:53 PM (in response to Ann Bens)A .264 file from x264Pro or MeGUI that is BD-legal will import into En and be automatically set to Do Not Transcode. So the file extension isn't the problem. There are some esoteric H.264 parameters in x264 that must be set precisely in order to have En set the .264 file to DNT. I suspect those same parameters will have to be set in MainConcept's encoder.
If you want to jump in the deep end, here are the x264 parameters that produce BD-legal output that also make En happy:
program --pass 2 --bitrate 16000 --stats ".stats" --open-gop bluray --interlaced --pic-struct --level 4.1 --bframes 3 --ref 4 --slices 4 --aud --nal-hrd vbr --b-pyramid strict --keyint 30 --min-keyint 3 --vbv-bufsize 30000 --vbv-maxrate 40000 --weightp 0 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --output "output" "input"
Obviously interlacing, bitrate, vbv-maxrate and such can be set as desired based on the source footage and delivery requirements.

23. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Jeff Bellune Feb 9, 2013 5:57 PM (in response to Ann Bens)Well, x264 isn't part of En and I think the OP is using the stand-alone MainConcept encoder. H.264 Blu-ray from either Pr or En using the built in MC encoder always produces files that don't transcode in En if a proper preset is used.

24. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
nordental Feb 10, 2013 2:31 AM (in response to Jeff Bellune)That's right, I'm using the standalone MainConcept Encoder.
Nevertheless, I have the impression that Encore also uses the MainConcept, because in the advance settings of the transcoding, in the line "Codec" the "MainConcept" is displayed (I cannot change this and cannot see other possibilities of Encding codecs).
However, I will control and compare theencoding parameters of the imported .264 file...

25. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Ann Bens Feb 10, 2013 3:13 AM (in response to nordental)Jeff: what i meant was this info about what legal BD parameters should be.
I assume the standalone Mainconcept Encoder will not be any different from the one Encore is using (or is there?)
So why not feed Encore the file from avid and let Encore encode.

Jeff Bellune Feb 10, 2013 6:07 AM (in response to Ann Bens)Jeff: what i meant was this info about what legal BD parameters should be.
Ah, I misunderstood. Sorry about that. You are correct -- that information should be available to the user. Adobe assumes everyone will encode with the built-in suite tools, but that's just not the case anymore.

27. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
nordental Feb 11, 2013 1:32 AM (in response to Jeff Bellune)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.

28. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)

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.

Jeff Bellune Feb 12, 2013 1:06 PM (in response to Matt Dubuque)I haven't used the stand-alone version, and the MainConcept web site doesn't have a lot of info beyond the fact that their version is expandable by purchasing more modules. I also don't know if they've tweaked their own encoder to produce better results than their licensed encoders.

32. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
Jeff Bellune Feb 12, 2013 2:41 PM (in response to Matt Dubuque)x264 is a superior H.264 encoder. Period. The only problem with MeGui is it doesn't have MPEG-LA licensing, which is a huge drawback for serious professionals. However, the x264Pro plug-in for Premiere Pro does come with an MPEG-LA license.

34. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
gr8bob Jul 31, 2013 7:23 AM (in response to Matt Dubuque)One more guy here trying to get Encore BD compliant files that don't have to be transcoded.
I'm a bit odd in that I'm trying to get more video on the disc, hence I'm telling Adobe Media Encoder (CS6) to do a max bit rate of 8 Mbs -- obviously not caring much about the video quality. What drives me crazy is that sometimes Encore will accept files as "Do Not Transcode", sometimes it wants to retranscode them -- I really don't think I've changed the Media Encoder parameters.
Hopefully the people with the knowledge are still looking at this thread.

gr8bob Jul 31, 2013 1:23 PM (in response to Jeff Bellune)Tutorial was very nice! But didn't directly answer my problem. x264pro maybe be worth the $299, but really seems Adobe should make life easier in this area without it. Found that if I keep video & audio in seperate streams coming out of CS6 Adobe Media Encoder, Encore accepts without retranscoding, at least for a couple of small samples I tested. Hate to have a bunch of extra files hanging around though.

Jeff Bellune Jul 31, 2013 1:32 PM (in response to gr8bob)Thanks for the compliment on the tutorial.
x264 does a better job than MainConcept at encoding H.264 video, and the main point of my tutorial was to show you to use the free tools to get it safely into Encore.
If you want to use the included encoder in Pr and En, then you still want elementary audio and video streams. It's not a "bunch of extra files", it's how professionals handle their assets.

Hqvideos Jul 31, 2013 2:58 PM (in response to Jeff Bellune)Jeff, this is a great tutorial. I have followed your steps but i am receiving an error in MeGUI upon opening the application after the frameserving has begun in Pr. Once i open MeGUI, i get the error message "Unable to render the file. You probably do not have the correct filters".
I am using CS5 and the source video is 1080i 29.97 fps. I considered using the x264 Pro trial version but it will not work in CS5.
Really motivated to get this to work the correct way.
thanks,

39. Re: Encore insists on transcoding H.264 Blu-ray encoded file (Blu-ray legal)
gr8bob Jul 31, 2013 3:19 PM (in response to Jeff Bellune)Well, actually "elementary streams" means double, not +1. I often play files on BLU-RAY player from thumb drive. I think I'll have to put video & audio back in single file to do that. So elementary files are a hassle. Multiplexed files that Adobe Encore creates are of type "m2ts", found in STREAM folder of Adobe Encore output. These can always be imported as asset back into Adobe Encore without re-transcoding. I wonder what's so magical about them compared to what comes out of Adobe Media Encoder?
