    Problems with Encore forcing transcoding

    Adrian_encore Community Member

      Hey,

       

      Recently I've been having some problems with Encore CS5.1 forcing transcoding on some files.

       

      I am using Premiere Pro CS5.5 to render a number of video files, all with the same output settings (H264 blu ray 1080/25p, PCM) and then transferring them to a different computer to import into Encore.

       

      Most of the video files are fine, and show "Don't Transcode" in the Blu ray transcode settings, but some of them randomly say "Untranscoded" with "Automatic" settings. If I import those same video files onto my machine with Encore, they show as "Don't Transcode". (We are transferring them to a different machine for a reason, so doing everything on my computer isn't really a solution).

       

      I have no idea why this would be happening. The project setting's max bitrate is way above what we are using, and the output settings are all exactly the same.

       

      Both computers have the same version as Encore and are both decently specced.

       

      Anyone have any ideas?

       

      Thanks.

          What do you mean by "randomly"? If a file shows "Untranscoded," does it then always show untranscoded if you reimport it? Or it might show "Do not transcode" the next time? If you reexport it from PR again, might it show "Do not transcode the next time"?

           

          How do the files vary; length? Any differences in bitrate? Are these VBR 2 pass or ...?

           

          Certainly makes no sense.

            So there were 7 files rendered on one computer, all with the same settings. H264 blu ray 1080/25p, 2 pass, 15-20mbit, max render quality, PCM. If I import these files into Encore on the rendering computer, they all come up with "Don't Transcode".

             

            If we move these files onto another computer, 2 of the video files don't come up with "Don't Transcode". One is the second longest (~40mins), the other is about medium length (~20mins). The rest are fine and come up with "Don't Transcode". There is no way to force "Don't Transcode" on the other files as there is no option where it should be.

             

            Reimporting it on that computer doesn't change anything (neither does creating a new project),  and we've had this problem a few times now on different projects. Most of the files are "Don't Transcode", some of them aren't. There doesn't seem to be any pattern to the files that don't work properly.

              No solution here.

              There doesn't seem to be any pattern to the files that don't work properly.

              But once a particular export from Computer 1 (C1) gets to Computer 2 (C2), it does not work consistently.

               

              Reimporting it on that computer doesn't change anything (neither does creating a new project),

              How about recopying it from C1 to C2?

              How about re-exporting it from PR?

               

              Same operating system for C1 and C2?

               

              There is a VBR 2 pass bug, but there is not a consensus on exactly how it works or whether it is always a problem. A workaround is to export as VBR 1 pass.

               

              And just to keep the picture clear, you said you render them from PR. I assume you are exporting from AME. True?

                That would be a good way of putting it. I have only tried importing the files to Encore on C1 twice, so maybe it hasn't been done enough to see the fault.

                I believe we have recopied it, but it's something to try again.

                I will have to get back to you on the re-exporting. The other person involved hasn't been keeping exact track of what files are going wrong.

                Yes same operating system (Win7 64).

                 

                For a bit of background, I am trying to solve this issue for two reasons. The first (minor) issue is that retranscoding the files are time consuming, and should be unecessary. The second problem is we've been having problems with the audio working on certain blu ray players. We are currently working through trying something else that I believe will fix it, but I thought this may be contributing, so should be fixed as well.

                 

                Interesting about the VBR 2 pass bug. We'll definitely give this a try. I've been using 2 pass because C1 has the spare time. I watched a tutorial today saying that 2 pass is unnecessary on the H264 blu ray setting, so I guess that means I'm going back to 1 pass.

                 

                Yes, I use AME for exporting.

                 

                Thanks for your help on this issue. The fault seems to make little sense, so it sounds like the VBR 2pass bug could be the problem.

                 

                I appreciate any other comments on the topic. I'll give 1 pass a shot and I'll keep this thread updated with the results.

                 

                Thanks again.

                  Do keep us updated.

                   

                  Reports indicate that the 2pass bug is fixed in CS6.

                    Most of the video files are fine, and show "Don't Transcode" in the Blu ray transcode settings

                     

                    I question that observation because 1080p/25 is not a Blu-ray compliant format.  Any such files would have to be transcoded to 1080i/25 (interlaced) to actually go onto disk.  The only ones that should be showing "Don't Transcode" might be the audio files.

                      Forgot to check that list when some were reporting okay:

                       

                      Encore-supported Blu-ray formats:

                        Ah, right you are. They are encoding at 1080/25i, my bad. I just had the Field Order field on automatic and didn't check the only options were Upper and Lower.

                         

                        The video files are definitely the ones showing both "Don't Transcode" and "Untranscoded". The audio files are all coming up fine.

                         

                        I have also discovered that we have been having problems with both 1 pass and 2 pass files. So that rules out the 2 pass problem. So I am using the MPEG2 bluray preset to see if that helps.

                         

                        So what else could it be?

                          Just curious if you have figured anything out further with this problem.  I have having a similar problem with a h.264 file right now.  Transcoded from Premiere to h.264 Blu Ray 1920x1080 60i. when I bring it into Encore it is wanting to transcode the video file again.  Both files were created using VBR 2 Pass, I guess I will try a VBR 1 Pass or CBR and see what happens.

                            This is an old thread, but as there are many similar ones and I haven't seen anyone reporting a fix, I thought I should contribute my solution.  In a nutshell, delete the XMP metadata files created by Adobe Media Encoder:

                             

                            - Quit the Encore project that is forcing transcodes and navigate to the location of the .m4v files that should normally be accepted without transcoding (those from Adobe Media Encoder).

                             

                            - If you find XMP metadata files alongside the .m4v files, move them somewhere else or delete them .  Their file extension is ".xmpses" (in the case of m4v files, it will look like "[same file name].m4v.xmpses").

                             

                            - Also delete the Encore cache associated with this particular Encore project

                               (1) "mlf.cache.v10"

                               (2) the entire "Adobe Adobe Encore DVD Preview Files" folder

                             

                            - Re-open the same project and let Encore re-scan the media.  All of mine came up as "Don't Transcode" after doing these two things.

                             

                            I'm not sure which of these two steps is required.  Possibly both.  I'm also not sure what this technique might "break," so please use your own judgement.  But I suspected that the XMP metadata --which I understand to be a hand-off mechanism to make sure the receiving Adobe app has more information about the file in question -- is simply full of incorrect information that is throwing Encore off.

                             

                            Hope that solves it for someone.  I'd love to know whether it works consistently and for others, so please post back.
