    Scrubbing is not smooth

    mikecox_ Level 1

      I thought I'd posted this question sometime in the past; the question line autofilled, but I can't find in in "my stuff" and I don't remember it being answered in any difinative way.

       

      I've been doing a lot of video edting latetly and when I scrubb through a track the image jerks and the scrubb action is not anywhere near as smooth as what I've seen in the video tutorials I've watched on Lynda.com.

       

      My question is; is this a feature of the graphics card, the processor, RAM, or how I have Premiere configured.  With regard to the latter  point, in CS6 scrubbing behavies the same way.

       

      I have

      1. Win7/64bit,
      2. 2 Quad CPU Q8200 @2.33 2.32 GHz,
      3. 6GB of RAM, and an
      4. ATI Radeon HD 5450 video card.

       

      I've been debating an investment a new computer; one designed for editing video.  But thats an expensive option and I'd rather upgade; if that will solve this problem.

          How smoothly your timeline plays or scrubs is a combination of:

           

          • Your processor power and RAM load
          • Which version of the program you're using
          • What model of camcorder your video is coming from and its codec and resolution
          • How closely your project settings are aligned with your video specs

           

          Your computer is more than adequate for any video editing. So the playback problems are most likely the result of your video specs not matching your project settings. What, if anything, can be done about this depends on what model of camcorder your video is coming from and what format and resolution it is as well as which version of the program you're working on.

            Thanks, I'm glad to hear that I may not need a new computer to get smooth scrubbing.

             

             

            I have been using Premiere Elements 11, with default settings, to edit my videos until today, when I tried the video editor in CS6; again with defalt settings.  I found the jittery scrubbing effect exactly the same in CS6.  So, the common feature would seem to be the computer and the video files I'm editing.  I'm assuming the default settings would be to maximise

             

            My video files are .mov files; from my Canon 60D.

                I agree with John. You should be using Premiere Elements' Add Media/From Flip or Camera to get the video from your camera to your computer. Sometimes this allows Premiere Elements to import it into the program in a format that the program can work with.

                 

                Premiere Elements can work with MOV files. However, because there are so many types of MOV files out there and they don't include the indicators that the program needs to identify them, the program often can  not use its automatic set-up to correctly set the project settings. This is why you're likley seeing yellow lines above your video clips in Expert view, an indicator of mismatch between project settings and video.

                 

                Try this: change the suffix on one or more of your clips from .mov to .m2t, then make sure that this is the first clip you add to your timeline. If the program is able to identify the video's specs and set the program to them, you should be able to add the rest of the clips in Expert view and they should have NO yellow lines above them.

                 

                If this works, your program will then edit this video very smoothly.

                  Did I miss something? 

                   

                  My issue, is not about importing clips or how to deal with the time constraints imposted by Youtube.

                   

                  I am trying to smooth the scrubbing action of already imported images.

                    Your pc is somewhat underpowered for dslr footage which is H.264 in a mov wrapper.

                      Also, we have been addressing your very issue.

                       

                      If you want to improve the program's performance, you need to match your project settings to your video specs -- something that is not possible with your current workflow. (Have you checked in Expert view to see if there are yellow lines above your clips -- a sign that you are not matching your settings to your video?)

                       

                      I guess it's up to you, but we're trying to help you troubleshoot this issue and fix it. Is this not what you're trying to do also?

                        Michael,

                         

                        I think you and I have been down this road elsewhere in depth from a computer, Premiere Elements, and source media point of view several months ago. Although your Timeline scrubbing issue seems to have remained the same, I do not know if your computer, source media, and project settings have changed from then until now.  But always good to revisit certain issues.

                         

                        But I need to remind you that you have been searching for such an answer for a long time (since the days of your VOBs and Premiere Elements) and have been given much input here (under different IDs) as well as elsewhere.

                         

                        The other day I was surprised and pleased to learn the good and bad news that you posted here about Premiere Elements 11 and Premiere Pro (presumed CS6) giving you the same level of unsatisfactory Timeline scrubbing. Specifically you wrote:

                        I have been using Premiere Elements 11, with default settings, to edit my videos until today, when I tried the video editor in CS6; again with defalt settings.  I found the jittery scrubbing effect exactly the same in CS6.  So, the common feature would seem to be the computer and the video files I'm editing.  I'm assuming the default settings would be to maximise

                         

                        My video files are .mov files; from my Canon 60D.

                        So, I would agree with you that the focus is to "the computer and the video files I'm editing". I would also enter into the equation your project settings.

                         

                        Last we interacted, you were thinking about buying a new computer and sought information at the Adobe Forums on that matter. Now you give your computer information as

                        1. Win7/64bit,
                        2. 2 Quad CPU Q8200 @2.33 2.32 GHz,
                        3. 6GB of RAM, and an
                        4. ATI Radeon HD 5450 video card.

                        Is that what you were using when we communicated a few months ago?

                         

                        As for your Canon 6D footage, is that new to your workflow? How long have you been working with it? What is your Canon 6D camera video setting, and what are the properties of your Canon 6D source media?

                         

                        What are you using as the project preset for your Premiere Elements 11 project? Are you letting the program take over and set it for you or are you setting the project preset manually yourself so that the setting agrees with the properties of your source media?

                         

                        Is your computer optimized at the present time? Have you been keeping up with the computer maintenance...clearing pile ups of previews, conformed audio and video?

                         

                        No one factor may be the answer, but a combination of factors may be negatively impacting your workflow.

                         

                        Please review and consider.

                          I have always used the Add Media option in Pr to import the MOV files from my HD; that I previously copied from my camera’s SD card.  I’m assuming that there is no problem with copying the MOV files from my camera’s SD card to my HD, then using the “Files and Folders” option an Add Media to add them as Media in Pr or CS6.

                           

                          I keep going back to the fact that I have Added MOV formatted media to both Pr and CS6 and in both programs I have the same problem; when I scrub the video seems to turn into a slide show, one image at a time instead of a speeded up video which allows me to hone in on a point in the clip.  It makes editing very frustrating as well as slow and tedious; because I’m always waiting for the video to catch up.

                           

                          Yes, in Pr, I do see a yellow line above my video clips, but it didn’t go away after I changed the file extension to .m2t, and scrubbing did not improve.

                           

                          Btw I have your book: “Cool Tricks & Hot Tips…”.  I’m doing a time lapse sequence with the help of Tip 24; which doesn’t require scrubbing.

                            Hi A.T. Romano; aka ATR, yes; as you well know, I have been down this path before and I am only here now because I got the feeling that you were not happy with my effort to get a “second” angle on the problem; you appeared to break off, so I continued pursuing this issue here and, as you can see, it remains unresolved.

                             

                            You don’t need to remind that I have been searching a long time for an answer to this problem, or that you and others have tried to help; for which I have always been grateful.  But the fact remains that I am still seeking a solution to this very frustrating problem; even if it means investing in a new computer; which it appears is not necessary. 

                             

                            In frustration I left this issue for a while, but now I am engaged in a rather ambitious project that I am shooting exclusively with my Canon 60D.  When I saw the tutorial on editing Video in CS6 (sorry, it’s all Photoshop to me; I have never sorted out CS6, vs Photoshop, vs PrPro or any of the other names associated with Adobe’s editing software, so forgive me if I use them interchangeably)  I jumped at the chance to try scrubbing in that program; only to discover that it was the same in both programs.

                             

                            Yes, I am still working with the same computer; so the information I provided in this thread is as it was.

                             

                            Currently I am only using media from my Canon 60D and have not changed the default settings on the camera because I am not familiar with them.  I’ve checked the menu options on the cameral and here are some of the settings I found;

                             

                            Rec size: 1920c1080/30.  Other options are 1920x1080/24, 1280x720/60, 640x489/60 and Crop 640/60

                             

                            All the other options, which don’t seem relevant, have to do with Exp, AF mode, ISO speed, highlight tone priority, metering, and sound.

                             

                            You asked about the project presets in Pr, but since the problem is common to both programs I would think it more of a file type issue than a program settings issue.  That said; here are my settings, from Preferences.

                              That is what I am inclined to think, and have said as much, but no one else has agreed with me on that point; so I have concluded that it's not an issue.  I would be more that happy to invest in a new machine if it would resolve this problem that I have been trying to sort out for a very long time

                                      I'm not sure it's relevant but my Canon is the 60D, not the 6D.

                                       

                                      Time clip I've been working with most recently is just over 3 min long.

                                       

                                      I exported the 1GB clip in AVI format, which took about 3 min to save; to a file 699 MB in size.

                                       

                                      1GB -> 700 MB? 

                                       

                                      Here is a screenshot of the settings:

                                      I then Added the AVI file to my time line and it scrubbs perfectly!

                                          Why am I getting this when I try to edit this message?

                                            Note that while it scrubs normally the preview is much smaller.  Also the organg line is over the AVI clip, not the MOV clip.  It used to appear on the latter

                                              a. With the project settings that you posted, when you drag your video to the Timeline as the first drag to the Timeline from Project Assets, do you have no colored line or any orange line over its contents on the Timeline?

                                               

                                              b. If so, please check the following and let us know the readouts:

                                              a. Right click the thumbnail in Project Assets and select Properties. I am particularly interested in frame rate among other things. Does it show 29.97 or 30 frames per second?

                                              b. Right click the thumbnail in Project Assets and select Interpret Footage. I do not want you to change anything there; I just want to know what the read out is for Frame Rate and Pixel Aspect Ratio.

                                                So are you seeing a yellow line above your clip on the Expert view timeline?

                                                Check out the screen shots I posted to ATR. 

                                                 

                                                I seem to recall that yellow line over the MOV clips but not now.   It does appear over the AVI clip I added to the timeline, but as you will see; the AVI file scrubbs perfectly, but the preview is half the size.

                                                    you do not have a colored line over the Timeline content of the .mov file. That would suggest that you or the program have set the correct project preset for the project and that you are now getting the best possible preview of that footage. Once you edit that .mov, it will go back to the orange/green rendering indicator process for each edit.

                                                     

                                                    The orange line over the .avi indicates that you are not getting the best possible preview, however it is scrubbing. What happens to the scrubbing on the .avi after you render that content?

                                                                    I have gotten my hands on a sample 1920 x 1080 @ 29.97 progressive frames per second video clip - AVCHD (MPEG4 AVC/H.264).mov - from a Canon 60D camera.

                                                                     

                                                                    I used Premiere Elements 11 Add Media to get it into Premiere Elements 11 Project Assets from where I dragged the clip to the Timeline (as first drag there in this project).

                                                                     

                                                                    There was no colored line over its contents, and Edit Menu/Project Settings confirmed that the program had automatically set the correct project preset for this project based on that video clip, that is, NTSC DSLR 1080p DSLR 1080p30 @ 29,97,

                                                                     

                                                                    When I went to play back that Timeline video in the Edit Mode Monitor, the Timeline Indicator "hopped along" rather than glide smoothly across the video from left to right. Since there was no colored line nor a green line over that Timeline content, the clip could not be rendered.

                                                                     

                                                                    Now this is what I did and what I would like you to try. We will consider the whys for why it is happening later.

                                                                     

                                                                    a. right click the video (with the no colored line over it), select Time Stretch, and set the Speed at 99%, click OK to exit Time Stretch.

                                                                     

                                                                    b. when you go back to the Timeline, you will see an orange line over the Timeline with all the implications that you are not getting the best possible preview, etc. Render the Timeline by pressing the Render button over the Timeline or going to Timeline Menu/Render Work Area. At the end of the rendering process you should now have a green line over that video content.

                                                                     

                                                                    c. now press the play button of the Edit Mode Monitor to observe the play back of the video there as well as the smoothness of the Timeline Indicator as it now glides across the video clip from left to right.

                                                                     

                                                                    Please review and let us know what happened when you did this.

                                                                     

                                                                    As for why the "hopping" for Canon 60D video cited, I can only guess, wild guess at that. I do not see this Premiere Elements "hopping" when using the .mov files I have looked at from different Canon models or Panasonic camera (but I have not done an exhaustive search and study on this particular matter). Premiere Elements Properties and automatic project preset setting mechanism seem to be interpreting what I would call the essentials of its video properties, but still... There was one bit of information that I dug out of an online review that may go to the problem cause..again guess...was the statement  "for the 60D, there are 8 extra rows of pixels beyond the standard 1920 x 1080".

                                                                     

                                                                    Just to focus in and make sure no information in falling through the cracks, you have seen this problem with just the Canon 60 D .mov files and not with .mov files from other sources or videos of another format. Correct or incorrect?
