    Encore is putting my files out of sink with the audio.

    KateMorgan Community Member

      Hi,  I have a completed sequence video file in PPro 5.5.  I make sure all the clips are "linked" to the audio source (the source is from recorded audio from a sound board)  I only use the on camera audio for sinking with the good audeo.  When all is done I also select the entire sequence and group it.  I make sure everything is sinked perfectly and also have another person check it as well.  When I send this to Encore to make a DVD it usually puts it out of sink by a split second but its noticeable.  Does anyone know what is going on?  I didn't have this issue with CS4.

       

      Thanks Kate

          Please don't double-post the same topic in different forums.

            Some audio formats are more likely to have problems. What video/audio formats? How are you getting it into Encore?

             

            Where are you seeing the issues? (Encore preview, burned disk etc)

              Jeff..this topic could easily be related to both PremPro and Encore and I would like advice from folks who work in PremPro and Encore on this issue as I am unsure which one is the culprit.  Sorry you seem to have issues with it but I will ask where I feel its necessary.

                Hi Stan,  I am using Prem Pro CS5.5 and I use the Dynamic Link to Encore and use Dolby Digital audio.  The files are sinked beautifully in PremProCS5.5.  It did work..once...when I grouped all of the files but not since.   It seems to be fine in Encore during the review but once it has been burned to the master DVD disc it is then out of sink...but just slightly.  The audio is consistanty around 3 frames ahead.

                  And as moderator, I will remove what I feel is unnecessary.  This is an Encore question; it stays here.

                    What do you mean by "grouped" the files?

                     

                    Try exporting from PR as MPEG2-DVD (demuxed), and import that.

                     

                    What is the footage in PR? (SD or HD)

                      Jeff,  I too am a moderator for another forum and when someone fairly new has "broken" a golden rule I will send them a private message letting them know what is up.  I would also ask the person where he or she would like to have their thread posted.  I don't decide for our member's where their posts should go but I make suggestions and explain the reason for the change.   As a moderator it is also expected of you to offer help as well as offering information on rules and to be sensitive.  I felt embarassed by the way you responded to my having the same question in two rooms.  You told me not to do something and never even offered a suggestion to help rectify the problem.. so what is that all about?? So what do you offer?  Can you suggest anything positive to my query?  If not I will repost in the other room where someone might have an idea of what is happening.

                        Hi Stan,

                         

                        After I make sure all the audio is "linked" to the video (visual) I then select the entire sequence, right click and then click on Group.  This allows one to move the file around, if necessary, without any of the clips becoming separated.  Its a wonderful tool.  This is done in PremPro.  Once selected I would then send the file to Encore hoping it will hold together during transit, if that was the issue but am not sure of course.

                         

                        My footage is HD and I've never had issues before now with sinking.  Sigh..  I had even tried exporting the sequence as an uncompressed AVI but it still degrades quite a bit when imported later into Encore.

                         

                        I'll try your suggestion and will let you know how it goes.  I appreciate the time you have taken to help me sort out this issue.  Its late so will give it another go tomorrow.  Thanks.

                          Many users have had a variety of problems with dynamic link with HD to SD workflow. So try exporting an asset that will be DVD ready on import to Encore. As Idescribed above, just use the MPEG2-DVD preset, and be sure to check the "use maximum render quality."

                           

                          This requires calculating bitrate if your DVD will be full.

                            First, why should you feel embarrassed? You did what you thought was OK, and I politely asked you not to because it wasn't.

                             

                            Second, as a moderator, you of all people should understand what problems can be caused by running concurrent threads by the same person about the same issue.

                             

                            Third, if I had helpful info I would post it.

                              Hi Stan,  Well I gave it a try  and found the quality of the video was very rough and overly compressed with the mpeg2 DVD preset, I appreciate your advice but I have to make sure the quality is at its best for my clients.

                               

                              I did figure out how to resolve the issue and I will  post this question and the result as well in the PremPro forum as it pertains to it instead of Encore.  Often, I add to the beginning of the sequence in PPro, a title crawl or still.  I usually need to start the audio a few seconds or frames in from the beginning so there is a gap that has nothing in it.  On spec I took a section of audio (any section) that was equal in size to the space and placed it in...thus filling the gap.  Naturally that piece of audio had the level placed to zero... and voila.  For some reason PremPro needs to have that gap filled or it will shift slightly during the transition.

                               

                              On the internet tons of people have this issue with PremPro so hopefully this will help someone else.  Cheers Kate

                                Kate,

                                 

                                As far as the Audio, in a lead in (and similar can apply to a lead out), many high-end DVD players take a moment to "lock" onto the Audio signal. This is a common problem with DD AC3 Audio, whether 5.1, or stereo. It is suggested that one allow ~ 02 sec. of silence at the beginning. In my Sequences, I always begin with 02 sec. of Black Video, and Dip-to-Black to fade up from black to my Video. I begin my Audio at that 02 sec. point. When that Audio Stream is Exported, I get 02 sec. of silence. Neil Wilkes, one of the MOD's here, refers to that as Black Audio. This keeps any gaps from the Audio Track in Encore, and gives DVD/BD players time to lock onto the Audio.

                                 

                                As there can be slight differences in the Duration of Exported Video and Audio (block size differences), I repeat that process at the end of each PrPro Sequence, by adding 02 sec. of Black Video and the Dip-to-Black Transition. My Audio always ends at the beginning of that Black Video, so I get 02 sec. of silence. The problem with an Audio Track, that is slightly longer, than the Video, is that the DVD-spec. was written primarily with Video in mind. With a longer (and I am talking just a handful of Audio Units here) Audio Track, then there is a gap in the Video - it ends short. That can cause problems in Transcoding, and often yields a "Failure to Return Frame" error.

                                 

                                Those little snippets of Black Video also make things easier, when the DVD player's heads have to reposition, which can cause a "black flash," and in my case, any black flash happens during black, so it is never seen.

                                 

                                Good luck,
