    Vanishing Audio Peaks (CS6)

    Steven Pribilinskiy Level 1

      Audio peaks quite often vanished when Zooming in the Timeline with Mouse/Keyboard.

      That wasn't an issue in earlier versions (CS5.5 and older). It happens in small projects too, 2 Audio Tracks (audio from 2 sources).

       

      Peaks are simply disappear, reopening the sequence doesn't help. I have to restart the Project/App in order to obtain the peaks. Sometimes setting Audio Gain forces to redraw Audio Peaks.

      Concise problem statement:Audio peaks vanished when Zooming in the Timeline with Mouse/Keyboard. Peaks are simply disappear, reopening the sequence doesn't help. I have to restart the Project/App in order to obtain the peaks. Sometimes setting Audio Gain forces to redraw Audio Peaks.

      Steps to reproduce bug:

      1.Create a New Project

      2.Import there 200 clips

      3.Create a Sequence

      4.Overlay Clips into the Sequence to 2 Audio Tracks (audio from 2 sources).

      5.Zoom with Keyboard and Mouse

      Results:Disappearing Peaks

      Expected results: that wasn't an issue in earlier versions (CS5.5 and older)

          Dude, you may want to wipe your system and reinstall everything from Windows on up.  You seem to be having a LOT of issues that I can't reproduce on two different systems.

            I have issues which I describe in Discussions - in Details.

            Please be also MORE specific. What issues you can't reproduce, can you make screen recordings?

            The system was reinstalled a week ago. Jim, probably you forgot http://forums.adobe.com/message/4440347#4440347

            Nope, clean Win7 SP1, nVidia 301.42, Premiere Pro 6.0.1, same thing

            It is possible that the CPU Q8300, 8 Gb RAM and the GPU GeForce 275 are the case of malfunctioning, but I wasn't in need to upgrade in earlier CS5.5  - there wasn't this issue. How about editing on a notebook with similar system? Or you want to say that notebooks should not be used for editing in Premiere Pro?

              The Hardware is not the case here, it is a Fault in Premiere Pro CS6 Code.

              I had a larger project with Microsoft DV AVI sources and there was everything fine.

              The problem is with handling the sources, now it depends from codec or container or whatever.

              Here's the Properties of the m2t/mpeg files I'm working with (gathered with MediaInfo tool):

              It's so regrettable that I have to convert sources of each project into a "native" avi/mov format so that the peaks will show normally instantly as in CS5.5 and older versions. So much troubles, this is one of the reasons to think about downgrading to CS5.5.

                Sorry but, my native MPEG sources do not display this behavior on either system.  (Including the 1/2 hour slate you let me download for another test.)

                  Please Jim, paste here your MPEG source MediaInfo.

                  The thing is that I can reproduce this behaviour on ANY system including yours if you let me.

                    I don't use MediaInfo.

                     

                    The MPEG clips are standard XDCAM, AVCHD, Nikon D7000 MOVs and some random Internet downloads using multiple audio formats like AC3, MPEG1 Layer 2 and MPEG 1 Layer 3.

                     

                    If you'd like me to download one of the clips that shows this behavior, I'll test it out on my end for you.

                      It would be great!

                      My sources are mainly from weddings - compressed from HDV to MPEG files. Duration varies from 4 to 6 hours.

                      Probably you will not experience this behaviour by just downloading a few clips.

                      Please download almost half of the shooting - it is 2.5 Gb, I prepared it as a zip file.

                          Hi Jim, how is it?

                            Sure enough the redraw sometimes takes half a second or so as I change scales.

                             

                            From what make/model camera did these files originate?

                              I still remember your rude suggestion:

                              Dude, you may want to wipe your system and reinstall everything from Windows on up.  You seem to be having a LOT of issues that I can't reproduce on two different systems.

                              But all in all, thank you Jim for downloading the sources and confirm the bug, you can count on me too.

                              Originals are doesn't matter, they were converted with AME to a compressed format and downloaded by a freelancer (me):

                              ame.jpg

                               

                              You can produce such files by yourself if you wish, if you still untrusty

                              You had to download the files to believe me, huh

                              Redraw problems are constant and after a long period of working time only a restart remains to force redraw.

                              Currently I have to convert the sources in each project with AME to DV AVI so that it will work like it should, without delays, instantly, on-the-fly, real-time, troubleless, hardware-system-software-drivers-independently

                              It is a bug, cs5.5 and older didn't have that glitch with compressed mpeg files, the bug is already filed 2 weeks ago and hopefully fixed in an upcoming bugfix release
