    DV Tape Capture and Scene Detect

    TMav Community Member

      I recently started using OSX. Previously I used Windows and never had this problem.

       

      Using CS6 Premier Pro on OSX Mavericks.

       

      I'm capturing DV tape from a Canon GL2.

       

      Both "Scene Detect" and "Tape" options selected.

       

      Two problems:

       

      1. Capture drops out at the first frame of video. I press record a second time and it proceeds to capture the rest of the tape. It almost looks like Premier is trying to determine the aspect ration of the material as the preview window appears to switch between 4:3 and 16:9.

       

      2. Scene Detect is off by a frame or two (not sure exactly how many). So basically the end of the shot has a frame or two of the next shot.

          1.You may not have enough pre roll at head of DV tape.

           

          2. What does 2 frames matter. You are going to edit the captured clips anyway.

          Hoping we dont hear too many other problems from you

            Well, I finished the video and those were the only problems I encountered.

             

            However, I am not new to premier. Just Mac. And I still don't understand why it's behaving this way during capture. All the years I have used Premier to capture footage I didn't have this happen. I would rewind the tape to the beginning, select "Scene Detect" and "Tape". In Windows it did not stop at the first frame of footage and all scene detects where 100% accurate.

             

            Seems like I must have a setting wrong in Premier on the Mac that I didn't have to set in Windows.

             

            Or maybe it's the Thunderbolt to Firewire 800 to Firewire 400 connection that's causing the problems?

             

            That has not seemed to be a problem for my Firewire audio interface though.

              Experiment with preroll and postroll and see if that helps. If the scene detect isn't perfect, at least you will have handles to work with.

                I don't believe preroll and postroll have any affect on scene detect.

                 

                I tried messing around with the Capture settings making sure GL2 was listed as the current device. Preroll Time and Timecode Offset did not affect Scene Detect which I figured they would not.

                 

                I would love to know if someone on Mac using Premier 6.0.5 has this working so I could narrow it down to something on my system. Perhaps the version of OS I'm using which currently is 10.9.1.

                 

                Or maybe it's just broken?

                 

                I checked iMovie and scene detect worked fine.

                 

                I did submit a bug report but I have a feeling that will not due to much good as Adobe has moved onto the cloud and want all of us there.

                  No, but as I said, if the clip starts early and ends late, you can easily trim it to the correct spot. A hassle I know, but what is a couple of frames here and there, after all. As long as they are available for your use.

                    Hello IDWDI -

                    I also have noticed the Premiere Pro problem with DV Capture, with the end of each clip having one frame from the next clip. 

                     

                    This with Premiere Pro CC and iMac OS X Mavericks.  Does not happen on with my Windows 7 PC using Premiere Pro CC.

                     

                    This DOES matter, folks.  I like to put Cross Dissolve between each clip, along with titles and Menu Markers, for example, so for it to look right, I have to cut off the one frame at the end of the clip, then do Ripple Delete to bring the next clip back to join the previous clip, then do Cross Dissolve.

                     

                    What a pain, especially with an hour DV tape, this Adobe bug (?) can mean 100+  edits I have to make to cut off the one frame at the end of each clip and ripple delete.   And now I have 16 miniDV tapes to do and output to DVDs with menus.

                     

                    So, Steven and shootenrz, yes it is a hassle -- one that any user should not have.

                      Well that's good to know, or should I say bad to know, I'm not alone. Thanks for the info about it happening in CC. That was one of the options, to upgrade to CC. The other is Final Cut. But Final Cut would be a big change as the whole timeline thing has changed so much in the new version.

                       

                      I suggest submitting a bug report as I have done. I believe it's the only way to bring it to adobes attention.

                       

                      And yes it is a big pain exactly got the reasons you mentioned. With the extra frames you have to double check all your edits, especially when using transitions like a cross dissolve. The extra frames are hard to detect but at the same time can make a transition look horrible.

                        Ok, I just submitted this Bug Report to Adobe.  Hope something happens.  I typed in all the following details so some employee might realize what a pain it is to deal with this bug.

                         

                        ******BUG******

                        Concise problem statement:

                        Using DV Capture, with Scene Selection checked, the captured clips have the end of each clip having one frame from the next clip.

                         

                        This with Premiere Pro CC and iMac OS X Mavericks.  Does not happen on with my Windows 7 PC using Premiere Pro CC.

                        What a pain, especially with an hour DV tape, this Adobe bug (?) can mean 100+  edits I have to make to cut off the one frame at the end of each clip and ripple delete.   And now I have 16 miniDV tapes to do and output to DVDs with menus.

                         

                         

                        Steps to reproduce bug:

                        1.  Connect a miniDV camcorder -- mine is a Canon ZR850 -- to the iMac with Firewrie 800.

                        2.  Choose File>Capture

                        3.  Click check-box Scene Detect at bottom right of the Capture window.  Then click on the TAPE button to capture the miniDV tape into your Premiere Pro CC project.

                         

                        Results:

                        Each clip brought in has the first frame of the next clip attached to the end of the clip

                         

                        Expected results:  Each clip should NOT have the first frame of the next clip attached to the end of the clip.
