    CS5.5 Multi-cam monitor

    Noberto.Clarkos Level 1

      Hey all,

       

      I am editing a multi-camera piece in my sequence and using the multi-cam monitor to see the other angles. The only thing is that I can only get realtime playback on the preview window and not in the multi-cam window, it only updates in the multi-cam window once playback has stopped.

       

      Is this normal or am I doing something wrong?

       

      Thanks in advance

          It's probably both, i.e. it's normal when you're doing something wrong...

          If mentioned 'preview window' is the Program Monitor, you shouldn't operate its Play button while editing a multicam sequence. You should use the one within Multi-Camera Monitor pane...

           

          If that's not what you're doing, you should explain your workflow with a bit more details.

            I am asking if it is normal to not have real time playback on the multi-camera monitor so I can view 2 video tracks simaltaneously. I am viewing video 1 on my preview monitor and on the multi-camera monitor I have selected video 2. I can watch video 1 and video 2 is frozen until I stop playback then it catches up to the most recent frame that the scrubber bar is now on? I am struggling to think of how else to explain myself. I want to see video 1 & 2 played at the same time, in sync with each other, not have one play and the other not then catch up when I stop playback on my sequence.

             

            And yes sorry, when I say preview I mean program monitor.

              1. Multi-Camera Monitor consists of two parts: camera angles previews on the left side and the resulting preview on the right side of the pan. When you hit Play button in Multi-Camera Monitor pan, you can see real time playback of all your camera angles and the resulting sequence preview within this pan, whereas Program Monitor is frozen and updates once you hit Stop.

               

              2. When you hit Play button in Program Monitor pan, you can see real time playback of the resulting muticam sequence, whereas everything, including camera angles, in Multi-Camera Monitor is frozen until you hit Stop in Program Monitor.

               

              3. When you scrub the playhead, irrespective of where it is: in Program Monitor, Multi-Camera Monitor or the Timeline, - you can see updates everywhere (real time or not, depending on your machine).

                I have that, 2 screens but they both show the same track. When I hit play on the multi-cam monitor I get real time playback of 2 screens showing the same angle.

                 

                2. When you hit Play button in Program Monitor pan, you can see real time playback of muticam sequence, whereas everything, including camera angles, in Multi-Camera Monitor is frozen until you hit Stop in Program Monitor.

                 

                Yes that is what I am saying, when I hit play on the program monitor,the multi-camera monitor is frozen but then catches up when playback stops. The opposite happens when I hit play in the multi-cam monitor, the program monitor freezes and then catches up when playback stops.

                 

                3. When you scrub the playhead, irrespective of where it is: Program Monitor, Multi-Camera Monitor or the Timeline, you can see updates everywhere (real time or not, depending on your machine).

                 

                Everything updates but there is some lag which isn't significant enough to bother me. I have been scrubbing using the timeline but that isn't the issue. I am asking if it is possible to view 2 different video tracks in real time. I am unable to do that.

                  If your Multi-Camera Monitor shows just two screens, I'm afraid your multicam workflow is a bit wrong. You probably didn't nest the sequence with different camera angles into a master muticam sequence, and, therefore, can see just one camera angle along with the resulting view of your 'multicam' sequence...

                   

                  In other words, when you created a sequence out of different camera angles, synchronised clips etc. etc., you need to nest this sequence into another one - a master (or a target) sequence. See this help section on multicam editing.

                    Right okay, I understand that. There lies my problem. I didn't realise I had to create a nested sequence to use multi-camera properly. Makes perfect sense though once you see the correct way!

                     

                    Thanks so much for your time and patience!

                      I'm having the same problem in Premiere 5.5.  I'm editing a 4 track multicam shoot.  One line cut and 3 isos.  I've built a master timeline with all four tracks synced and then nested it into a sequence that I enable multicam on.  When I open the multicam window and start running the timeline it plays fine for about half a second then the video starts locking up on both the program screen and the 4 way split.  After about another second both screens freeze completely and only update to the current frame when the playback is stopped. 

                       

                      I don't think it's a matter of system resources as I'm only showing a 25% hit on my CPU (core i7) and only a moderate hit on my 16gb of system memory. 

                       

                      Suggestions?

                        If you have the same issue, you already have the answer: check your multicam workflow, Program Monitor and Multi-Camera Monitor do not play in sync unless you're scrubbing the timeline.

                         

                        If you don't have an answer, then your issue is probably not the same (at least for me it's not clear, what you are doing and what you expect to see: whether you expect Multi-Camera Monitor and Program Monitor playback the timeline in sync, or you hit Play within Multi-Camera Monitor and it plays back just for about half a second and then freezes, or you're scrubbing the timeline and expect real time playback, or something else...).

                          Could be over taxing your hard drive? I can do 4 angles of cannon .mxf  1080 anamorphic and AVCHD 1920x1080  with gpu accelerated fx on each track.

                            OK... let me be clear based on the above issue and my interpretation of what the original poster was trying to say... I have a four way split showing all my tracks on the left side (what I call preview) of my multicam window.  On the right side (what I call program) of the multicam window I have the program or output of hte multicam cut.  When I open the multicam window, behind it in the regular workspace are the original program/preview windows.  When I play the video in the multicam window I get the freezing issue while the program window behind it continues to play fine. 

                             

                            What I expect to see is the multicam window playing continuously.

                              2TB USB3 hard drive - brand new.  There's only about half a TB on it.  I can't see how I'd be over-taxing it.  My only qualm about using USB was it's speed but I was assured that USB3 is actually considerably faster than eSATA so that's why I went with it.  I suppose I could dump everything into the system drive and try that.

                                Sorry, I can hardly explain it better: you can't see your multicam sequence playing back in both Multi-Camera Monitor and Program Monitor at the same time unless you're scrubbing the timeline... Press Play button within Multi-Camera Monitor window (or select Multi-Camera Monitor window first and then hit spacebar) so as to play your multicam sequence back in Multi-Camera Monitor. Sequence playing back in Program Monitor on a background indicates that you're not in Multi-Camera Monitor window... Otherwise I do not understand you completely...

                                  I am playing it in the multicam window.

                                    If you hit Play within Multi-Camera Monitor and it freezes after about half a second, whereas the multicam sequence is mystically playing back in Program Monitor, - then sorry, I can't reproduce such PrPro behaviour.

                                     

                                    If you hit Play within Multi-Camera Monitor and it freezes after a while, whereas Program Monitor is frozen as well, then your issue does not relate to the OP one, and possible causes may rooted in either your spec or footages you are editing. In this case you'd rather start a new thread with the comprehensive description of your issue, including all your spec and footages details.

                                     

                                    If the issue is caused by footages, which are 'heavy' enough to play four of them in real time on your machine, try to transcode them into something 'lighter'.

                                      on the left side (what I call preview) of my multicam window.  On the right side (what I call program)

                                       

                                      Those aren't the right terms.  On the left you see the "angles".  On the right you see the "preview".  The Program Monitor is a separate thing and not part of the Multicam window.

                                       

                                      With the Multicam window open, the Program Monitor will not update during recording or playback.  The angles and preview inside the multicam window should play fine.  Are you saying they don't?

                                        Well I guess I'm what they call old school.   In my world as sports truck Director and Technical Diretor, anywhere you see your sources before putting them to air is "preview" and anywhere where you see the output is program.  I'm not sure, though, why the industry has to reinvent the wheel and change terminology from what it's been for years.  Guess you can't teach an old dog new tricks. 

                                         

                                        At any rate, to answer your second question... no they do not play fine in the multicam windows.  I do see all four sources in your "angles" pane on the left and the output in the "preview" pane on the right.  When I hit play in the multicam window they play fine for about half to one second both panes begin to intermittently freeze for about another second then they both freeze completely.  I can shuttle (scrub in your world) through the main sequence and the multicam window will play with some jerkiness but it's not stable enough to be useful.  If I hit play on the main sequence window both the program and the multicam windows will play but will do the same lockup thing after a couple of seconds. 

                                         

                                        I'm just copying my project off of my external drive to the internal drive to see if that helps things out.  I'll update when that's done in an hour or so.

                                              OK as promised here's an update... I moved all of the project off of my USB3 drive (including all source footage, graphics, etc.) and on to the internal system drive. 

                                               

                                              It made no difference in the freezing issue in Multicam.  So it would appear that USB transfer speed is not the issue.

                                                      Are you using MPE hardware or software acceleration? Open CL acceleration?

                                                       

                                                      Have you tried lowering the preview resolution to 1/2 or 1/4?

                                                       

                                                      I'm thinking that your gpu might overwhelmed.

                                                      I have no idea on the acceleration issue and in multicam mode there is no option for lowering the preview resolution that I've been able to find.

In lots of those cases, there should be no render bar colors when a clip is placed in a sequence that matches the format, only adding colored render bars when an effect or transition is applied to the video.

If you make a duplicate of your sych sequence, can you shrink each clip down in the motion settigs of the fx control tab, then fit all 4 clips on the program screen at once, then play them all at once on the timeline without freezing?

If you make a duplicate of your sych sequence, can you shrink each clip down in the motion settigs of the fx control tab, then fit all 4 clips on the program screen at once, then play them all at once on the timeline without freezing?

                                                                                  Just tried the four way split screen and it works fine with no freezing.  Still locks up in multicam.
