    Importing 720p @ 25 frames makes audio and video out of sync

    ndanaylov

      Greetings,

       

      I am trying to edit a video with Adobe Premiere Elements 12.

       

      The video is at 720p @ 25 frames per second.

       

      When I play the video on its own in VLC or media player the video plays perfectly fine.

       

      The problem is that when I import and try to edit in Adobe Premiere Elements 12 the audio and the video go terribly out of sync.

       

      How do I fix and/or avoid this issue?!

          What are you or the program setting as the project preset for this project.

           

          Please check Edit Menu/Project Settings/General and let us know the readings for Editing Mode, Timebase, Frame Rate, and Pixel Aspect Ratio (even if they are grayed out).

           

          What is the source of your video and what are its properties - video and audio compression, frame size, frame rate (variable or fixed), interlaced or progressive, file extension, pixel aspect ratio.

           

          We could get into other areas, computer resources, video cards, and on and on. But, let us first rule in or out the prime candidates for causing this issue and then we can plan further troubleshooting strategy accordingly.

           

          Thank you.

              The video is a skype recording via SuperTinTin. Here are its properties: video properties.JPG

                I suspect that the issue is stemming from the default project settings - how do I change thouse to 720HD 25p?!

                  Ndanaylov,

                   

                  It appears that your Project is set to 1080i @ 29.97 FPS, and your source is 720 @ 24.98 FPS. That mis-match can cause issues.

                   

                  As a test, I would create a New Project for 720 @ 24.98/25 FPS, Import one of the Sykpe files into that, and see if the sync is now better.

                   

                  Good luck,

                    I get that very well Bill,

                     

                    The problem is that I don't know how to create a new project with the above specs...

                     

                    Thanks for your help!

                      From the Weclome screen, choose New Project. When that opens, immediately go to File>New Project, and choose the 720p PAL HD option. I would also check Force Setting, rather than trust PrE to make that choice, or change it for you, since you know the characteristics of the video file.

                       

                      Good luck,

                        I tried doing that Bill and changed the settings a million times to pretty much everyone with 720 and 25 or 24 frames. Still the audio and video are totally out of sync when I import the file...

                          Just starting my day and have just seen the communications between you and Hunt.

                           

                          You definitely have a mismatch between project preset and the properties of your source media. The program is giving you its default project preset instead of the one more appropriate for your source media which appear to be

                          1280 x 720 @ 24.98 progressive frames per second

                          I have not seen 24.98 as a frame rate unless the recording is using a variable frame rate.

                          The typical for a constant frame rate would be 23.97 or 24.00.

                           

                          So, I see that as two issues, correct project preset and use of a source with a variable frame rate.

                           

                          If we were dealing with just a video with a fixed frame rate 23.97/24.00, then set the project preset manually to the following:

                          PAL

                          AVCHD

                          AVCHD LITE 720p24

                           

                          But, I would ask "Is your audio Stereo (2 channels) or 5.1 channel)?"

                          Premiere Elements does not have a "AVCHD LITE 720p24 5.1 channel" project preset, but if necessary I can tell you step by step how to create one.

                           

                          I have not run into problems with out of sync audio with iPhone 5 and iPod Touch 4th generation footage (each using variable frame rate). Others have. We had a recent post from Italy on this matter. The user posted a link to the problem video and I confirm the out of sync audio. His solution was to change the variable to a constant frame rate using Handbrake. Others have suggested QuickTime Pro in this type of "fix". It is hoped that the video now with the fixed frame rate will import into Premiere Elements (with the correct project preset) without any out of sync audio problems.

                           

                          But before adjusting to constant frame rate, let us look more closely at the project set with considerations as cited in this post.

                           

                          If you want to post a link to a Dropbox sample of the problem video, I would offer to look at it in my Premiere Elements.

                           

                          Thanks.

                            A just in case note to my prior post numbered 9 - regarding checking out project preset considerations to the fullest....

                             

                            To set the project preset manually....

                             

                            Open a new project

                             

                            Go to File Menu/New/Project

                             

                            Change the project preset to PAL AVCHD AVCHD LITE 720p24

                             

                            Before exiting the final dialog, make sure to place a check mark next to "Force Selected Project Setting on This Project".

                             

                            Then back in the Premiere Elements Expert workspace, import your video into the project with Add Media/Files and Folders/Project Assets - Timeline.

                             

                            Do you have an orange line at the top of the Timeline (above Video 1 where the content is)? If so render the Timeline by pressing the Enter key of the computer main keyboard or the Render button above the Timeline to get the best possible preview of what you have. This might be an answer...needs to be ruled in or out. Rendering can be time consuming but it is your window of opportunity to catch a problem or rule it in or out sooner than later.

                              I do not have a drop box account but can send you the files via Amazon S3 or via SkyDrive.

                               

                              Would you be so kind to have a look if I upload the file so you can download it and see how I can edit it in Adobe Premiere Elements 12 without the audio and video going out of sync?!

                                I have not seen 24.98 as a frame rate unless the recording is using a variable frame rate.

                                That could be the issue. Some video screen-cap, and similar programs, DO record at Variable Frame-Rates, i.e. Variable FPS.

                                 

                                Good catch.

                                  I tried this step by step ATR and it does not work - stil have the same issue. Should I uplaod it to SkyDrive or Amazon S3 so that you can have a look?!

                                    I am used to the link to the Dropbox download, but have no experience on how to handle SkyDrive or Amazon S3. Is the SkyDrive the Google feature? I think that I am OK with that but I am not sure if file size will get in the way of successful handling of the file by SkyDrive.

                                     

                                    Is it a matter of just clicking on your posted link for SkyDrive or Amazon S3?

                                      Then you can download the file and see that when you play it in VLC or Windows Media Player it plays totally fine with video and audio in sync. Then please import to edit in Adober Premiere Elements 12 and you will see the out-of-sync issue that I am struggling with.

                                        Weird! In PRE12 its around 4 seconds adrift. If you unlink Audio/video and shift the video 4 seconds plus a few frames to the right you can get it back into sync and it looks to stay there (using Preset PAL HDV 720p 25).

                                         

                                        I haven't found a setting that doesn't require the timeline to be rendered.

                                          I am doing podcast episodes every week or so. Thus I need a permanent solution to the sync problem so that I know how I can resolve it quickly and efficiently after each and every recording.

                                           

                                          Is that the best we've got so far?!

                                                Looking forward to seeing what I can do with it.

                                                  I see from the SuperTinTin site that it says 'can be edited in Adobe Premiere'. Maybe Bill Hunt could try your file out in Premiere Pro and see if the sound is still out of sync. If it is then it's probably time for you to contact the SuperTinTin people.

If you check Interpret Footage, we learn that the program is interpreting the frame rate from the file as 24.9790 frames per second.

                                                     

                                                    If you take this same file into Premiere Pro CS2, it fails to import at all. Message "Format Not Supported". This earlier version may be giving that message because AVCHD support may not have come to Premiere Pro until a much later version?

The .wmv export from that program can be imported into Premiere Elements 12 with video and audio in sync.

                                                     

                                                    I had a write up on preliminary results with Handbrake. At this point I am having far too many problems with it to report on its applicability in this instance. I do not know if QuickTime Pro would run into the same problems.

                                                    Any chance you can control the recording settings so that you record with a fixed frame rate rather than a variable one. The discrepanies between the frame rate properties readouts between readout programs is disturbing.

Can you confirm what version of Premiere Pro first supported AVCHD?

I get a great 30 sec HandBrake preview that works fine in Premiere Elements 12, video and audio in sycn after the Handbrake constant frame rate (24 fps) set for the export. But the master export is now giving me "not supported" in Premiere Elements 12. I need to figure out what that is all about.

                                                            I am still Exporting the file in QT Pro, with a fixed Frame-Rate, and when done, will try the file in PrPro CS 2 (expect the same issue that you observed) and PrPro CS 6. The QT Pro Export is taking quite a while, and I should probably have done a heavy Trim on the video first, but have begun the Export, so will let it run completely. Also, if the OOS is dynamic, i.e. it drifts more over time, having the full video will allow me to check for OOS, all the way to the end.

But, even there, it took quite some time for Windows Live Movie Maker to "prepare" the video for import before it got into one of its projects for export.

But, is there any reason why you are reporting on 15 minutes of the footage and not the full duration of the original .mp4 file (about an hour)?

It could have managed the whole file.

There are other algorithms that use DIVX compression, but I suggest you avoid them, I don't think they'll edit well.

                                                                            http://download.cnet.com/HandBrake/3000-2194_4-10808250.html

I thought that the 100% in the progress bar at the bottom of the interface meant "conversion completed" which is not the case. I needed to wait for the "Queue Finished" before I had the whole converted end product. Before that revelation, I was getting video of limited duration that was giving me a format not supported message in Premiere Elements 12. Using HandBrake, it took a total of about 35 minutes to get the "right" converted end product for your 1 hours+ .mp4 that subsequently imported and worked in Premiere Elements 12 with audio video in sync.

The converted  AVCHD (H.264) was complete with about 35 minutes.
