    Video Audio Sync issues

    jhartne

      Hello everybody. I'm back with a problem that I have had before. I love to record videos with my live gamer HD by AVermedia and they require editing, so Adobe Premiere Elements 11 is my editor. Whenever I playback the video that I have just recorded on my screen on Windows Media Player, everything is perfect. But then whenever I import it into Adobe Premiere Elements 11 and play it back, the audio de-syncs from the video. I record my gameplay footage at 30 frames per second, my video bitrate is 60.0 Mbps, and my audio bitrate is 128kbps. Please Help!

          Could you post a MediaInfo (tree version) property readout for your video file that you are importing into Premiere Elements 11 and ending up with out of sync audio? What is your computer operating system?

           

          You said you had this problem before. How did you resolve prior problems and, if so, how?

           

          I will check your prior threads to see if I can get some history on your situation. But, more details from you would be very helpful.

           

          We need to know the properties of what is coming from AVermedia and what flexibility in recording settings are offered by this recorder.

           

          More later.

              No version of Premiere, Elements or Pro, will properly edit variable frame rate video

               

              You must have a constant frame rate to edit in any version of premiere... more information below... about iphone video, but the IDEAS may help

                What?!?! This is unacceptable. All editors ever made should support variable frame rate. Especially Adobe products. I am very disapointed with this, I spent $60 for nothing apparently. I got this editor for video editing my footage. Now its useless. Thank You.

                  If you are inside 30 days since purchase, contact the place you purchased for a refund

                   

                  As far as what "should" be done, tell Adobe at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform

                   

                  But, don't hold your breath while waiting... this is a OLD issue, discussed many times, so don't expect Adobe to do what you want

                   

                  Variable Frame Rates for editing are a very small subset of the video market, and Adobe aims development efforts at the majority of the market

                      Wish I could help more, but I'm just another user... I suggest you contact  AVermedia to find out if there is a way to save as a constant frame rate, or if they have a program to edit the video they produce

                        Please do not go away just yet.

                         

                        No version of Premiere, Elements or Pro, will properly edit variable frame rate video

                         

                        I disagree with that generalization. I have used Premiere Elements 11 and other to edite successfully video (iPod, iPhone 5). Although some have generalized that out of sync audio and variable frame rate are bonded, I have not found that to be written in stone. Each case needs to be evaluated on details specific to the circumstances.

                         

                        1. Can you record your video with this AVermedia product at a fixed frame rate of 29.97 progressive frames per second? Then evaluate that along with the following.

                         

                        2. Open Premiere Elements 11 to the Expert workspace. Go to File Menu/New/Project and set the project preset manually, selecting

                        NTSC

                        DSLR

                        1080p

                        DSLR 1080p30

                        and, before exiting the new project dialog, place a check mark next to Force Selected Project Setting on This Project.

                         

                        3. Back in the Premiere Elements 11 Expert workspace, Add Media/Files and Folders/Project Assets from which you drag you video to the Timeline.

                        a. Is there a orange line over the Timeline content? If not, are the video and audio in sync once at playback in the Edit Mode monitor?

                         

                        4. For export, look at Publish+Share/Computer/AVCHD with preset = MP4 H.264 1920 x 1080p30. The default bitrate under the Advanced Button/Video Tab is Target 32 Mbps Maximum 40. If you leave the Profile at Main and the Level at 4.2, the bitrate opportunities will range from 0.19 to  50 Mbps. If you change the Profile to High and set the Level at 5.1, then the bitrate opportunities will range from 0.19 to 300 Mbps.

                         

                        Please look at the audio sync before and after encoding.

                         

                        Depending on the results, then I would go back and look at the recorded source with a fixed frame rate (if you can produce such a species). Also, look at lowering the video bitrate from 56 Mbps to 40 without losing quality as you get a smaller file size.

                         

                        We will be watching for your results which will guide us in decision making.

                         

                        Thanks.

                          1. Here is exactly what AVermedia said to me:


                          To answer your question the official support is for 1080p60fps,
                          the file will be recorded as 1080p30fps.

                          There should be no problem for the device to record from source with 29.97 fps. Recorded file
                          fps will be adjusted.

                          If you have any further questions please don't hesitate to contact us!
                          Best regards
                          Avermedia Support

                          2.There is an orange line over the Timeline content, and the video and audio are not in sync when i play them back in the Edit Mode monitor.

                          3.After I exported it the audio was out of sync exactly the same as in editing.

                            1. Go through the export details as previously cited, but this time use the Premiere Elements project preset

                            NTSC

                            DSLR

                            1080p

                            DSLR 1080p30 @ 29.97

                            Then let us know if you get the orange line over that Expert workspace Timeline when the video is dragged to the Timeline.

                            (A just in case note, this orange line to which I refer is above the Timeline content. I am not referring to the horizontal orange line that runs through the middle of your video clip (line is called rubberband, represents Opacity) and your audio clip (also called rubberband, represents Volume)

                             

                            2. Do you know if you can alter the bitrate of the video that you are recording...say 40 Mbps instead of 56 Mbps?

                             

                            Thanks.

                              The orange line was there when I did the intrustrions before that you told me and it is still here on these intructions, and I am aware of what orange line we were talking about I just worded my last post badly. Sorry about that. And I can alter the bitrate if that helps. And also, do you want me to put the video I exported into premiere elements? If this is true then I messed up. The orange line was still there on the intructions you gave me before your last post.

                                It is a long shot, but interested to see what the video bitrate down from 60 Mbps will do to the audio out of sync issue.

                                Add On...Depending on how things go or do not go, is there any possibility of nudging the separated audio and video into place....

                                Alt hold down, as you tap the right or left arrow key for a 1 frame per tap nudge. And, Shift+Alt hold down, as you tap the right or left arrow key for a 5 frames per tap nudge?

                                  How do you seperate the audio and video? And how low do you want me to lower the bitrate? To 40.0Mbps?

                                    If you have linked video audio on the Timeline, right click the file there, select Unlink Audio and Video.

                                     

                                    If you wanted to get rid of the audio in such a case, right click the file there, select Delete Audio.

                                     

                                    Likewise, if you wanted to get rid of video in such a case, right click the file there, select Delete Video.

                                     

                                    There is also a techique to separate video and audio where you hold down the Alt key of the computer main keyboard and drag the audio from the video....I less prefer that.

                                     

                                    Taking the video bitrate to 40 Mbps would be good as a baseline...either it produces an effect or it does not. If it does, then we can adjust from there.

                                     

                                    Thanks for giving those factors a look at.

                                      Oh my! Changing the bitrate definitely produced an effect! The clip is in sync. I think this may be the solution! Let me test this.
