    Stabilize a Multicam Clip

    ExactImage Level 3

      This is driving me nuts!    I'm used to being able to right click on a clip in an FCP timeline and say send to motion - stabilize *just that part of the clip* and return to FCP.  Job done.   Not so in Premiere Pro AE it seems.

       

      So, here's the problem.

       

      4 Cameras - each have long clips.   As I've cut them in Multicam I need to take out a small wobble in a 6 second section of (say) track 3.    If I right click on this clip and replace with an AE comp so I can stabilize it the entire multiclip appears in AE and it now wants to stabilize the entire 40 mins rather than just this 6 second piece.  Crazy.

       

      What is the easiest / fastest workaround for this?    Stabilizing the entire 40 min clip is not practical for several reasons, including the time taken to analyse (many hours) and the fact that the camera moved position in this time so the footage wouldn't even match anyway!

       

      Help!  Going crazy since I'm trying to get this project finished and delivered..... it's the first Multicam I've done in PP after switching from FCP7.

          First, I'd create a nest with the track/angle that contains the wobble--you'll see why in a second. Climb into that nest, mark the region with the wobble using the Work Area Bar, and export that segment of the sequence to an uncompressed clip (MOV or AVI, depending on your platform).

           

          Import that clip back into PPro, and drop it on a track above the original clip in the nested sequence--you'll still have your WAB marks so you'll know right where it goes. If the original long clip is on V1, your exported/imported clip will be on V2. Right-click it, and select Replace with AE Comp. You can now do your stabilization on just that bit--should be much faster. Since it's a DL comp, it'll be immediately updated in your PPro sequence.

           

          The reason you nested the original track/angle is because the multi-tracked sequence will act as a single track in the multicam sequence. It gives you the flexibility of simply turning off the visibility for the fixed segment, should you decide you don't want to use it.

            This seems a rather long winded way of doing things compared to the promised right click integration

             

            FCP / Motion does this much better / faster. 

             

            So, if for some reason during a 1 hour show I have 10 wobbles to fix, I have to export 10 files, re-import and place 10 files and only then can I send them to AE?

             

            Pfft.

             

            Ok Adobe, this one definitely needs cleaning up!

              It would probably take you about 30 seconds per segment. If it's all in one angle, maybe 20 seconds. I guess I don't see the connection here to "the promised right click integration?"

                Perhaps, I missed something... Correct me, if I'm wrong...

                 

                Supposing, I had several long multicam shots. I placed footages into nested comp and synchronised them (specially for you: total movie length is of about 55 min):

                Multicam. PrPro. Nested Seq.jpg

                Then made cuts on Master sequence via Multi-cam Monitor:

                Multicam. PrPro. Master Seq.jpg

                Found out that my movie needed stabilisation right from 15:00:00 to 15:05:00.

                OK. Made two extra cuts on 15:00:00 and 15:05:00:

                Multicam. PrPro. Extra Cut.jpg

                Replaced that short clip with AE comp. Checked nested AE comp for proper camera view:

                Multicam. AE. Nested comp.jpg

                Applied Warp Stabilizer onto my short AE Master comp (it was actually completely useless footage, just for playing around)

                Multicam. AE. Warp Stabilizer.jpg

                It took of about two minutes to calculate all the stabilisation within AE

                  If that's all it took, I'd be reasonably happy.  the problem is that those 5 or 6 seconds suddenly turned in to 1hr 55 min analysis because it wanted to analyse (or appeared to want to analyse) a MUCH larger portion and not just the 5/6 second clip.

                   

                  Honestly, if 2 mins analysis was the problem it would be no problem at all, I'd deal with it, but that doesn't appear to be the case - unless I'm doing something wrong!

                    What you're encountering is one of the ramifications of native format editing as provided by Premiere Pro. Unlike FCP7, where footage is transcoded or rewrapped on import, you're working on the camera originals--and in your case, they're rather long recordings/large files.

                     

                    Though I have no experience with it, what I'm assuming FCP/Motion does is extract a segment of your clip automatically and create a new MOV file of the segment you want to stabilize. That's why it's (relatively speaking) much faster to do this particular process in FCP. What I'm offering is a two-step to accomplishing the same thing in Premiere Pro and AE. Both Premiere Pro and AE work on the camera originals, so they are imported wholesale without any trimming; when you use Warp Stabilizer, it therefore needs to analyze the whole clip. Yeah, it might not be as elegant, but I can say that almost beyond a shadow of a doubt that you will never see this kind of process in PPro--it flies in the face of native format support.

                     

                    Considering the time savings that native format support provides, I still think you're coming into home plate much sooner with this workflow than you would be when accounting for a transcode/rewrap.

                      It SHOULD analyse the length of your SHORT AE MASTER comp (in case you apply Stabilisation - as well as any other effect - onto it)

                       

                      Just for the sake of playing around.

                      In AE duplicate your long nested comp (and give any name you like).

                      Because it linked with your short AE Master comp, you are able to trim it exactly as you want:

                      - press Home when you're in your Master comp;

                      - switch to your brand new nested one, press B - it sets up the beginning of Work Area (and then if you want select appropriate leyer and press Alt+[ / Opt+[);

                      - switch to your Master comp back and press End;

                      - switch to brand new nested comp and press N (also optionally press Alt+] / Opt+] to cut your layer);

                      - delete all unused layers, choose Composition -> Trim Comp to Work Area;

                      - apply Warp Stabilizer onto trimmed brand new comp;

                      - import it via Dynamic Link into PrPro;

                      - enjoy (at least, I hope so...)

                        It won't. Even if you create, say, a 1-second comp from a 1-hour clip, that entire 1-hour clip is available for that 1-second comp. As a result, AE must analyze the entire duration of the 1-hour clip, because it is a single footage item. That's the reason for my export/import/DL workflow suggestion. You need to hard limit the amount of footage that AE will analyze, or you wait... and wait... and wait.

                              Trimmed composition was extended up to 7 seconds

                                Well.... Fuzzy.... I just can't get mine to operate like yours.  Scratching my head here.

                                 

                                I'm currently using Colin's workaround, and while it works it does create extra files I need to manage in the project bins  

                                 

                                Finding a way to make it would like Fuzzy's would be a much better solution.

                                  But where and when issues start to occur?

                                  Are you able to upload any of your original footage sample so that I'm able to play?

                                    I can't find ANY clips that are shortened in AE - they all want to analyse the full clips.

                                     

                                    Create a color matte in PP - say 10 mins long, maybe red in colour then export that as a 10 min movie.  Change the color to green and export, then blue and export.

                                     

                                    Bring all three exported clips back in to a single sequence, nest and create multiclip.  Change screens every 10 seconds or so.   At 3 mins in tell it you want to stabilize that clip and tell me what you get......

                                     

                                    For me it wants to analyse a 10 min clip, not a 10 second clip.

                                          That means you may treat your PrPro Master sequence as a common one.

                                                          The resulting sequence on which you apply cuts via Multi-cam Monitor is 'Master sequence'.

                                                            So, I have a 10 second cut in the multicam sequence.   Before this cut is (say) Track 1, this is track 2, the next clip is track 3.

                                                             

                                                            I want to stabilize the 10 second (i.e. the entire section) for track 2 in AE.   Where do I put these extra cuts?   I've tried cutting there and it make no difference (after all it's already cut there within the sequence.

                                                              It was just an example.

                                                              If you have say 30 seconds Track X clip but want to stabilise just a piece of them, say 5 seconds, you cut out these particular 5 seconds.

                                                              If you want to stabilise all 30 seconds, no extra cuts.

                                                                    - Nested comp, which is exactly you Nested PrPro sequence.

                                                                        Now get back to our first discussion about possible bugs in Multi-cam while replacing a clip with AE comp.

                                                                        Switch to the comp with all your layers and disable eyeballs of all upper layers, which overlap your proper camera view.

                                                                        When you just replaced your multicam clip with AE comp, playhead is in proper position.

                                                                        When you switch to the comp with all layers, the playhead somewhere in the middle, but all the layers are arranged in relation to camera views.

                                                                        You know from PrPro which view is proper, so you know which eyeballs to disable.

                                                                        Have a look at our Colour Matte play. I put Colour Mattes into Nested PrPro sequence in the following order from bottom to top: Blue, Green, Red.

                                                                        I know that I need to bring back my Green view, hence I disable eyeball of just Red Matte.

                                                                         

                                                                        Now jump back to AE Master comp - proper camera view is here, and just the length we need.

                                                                        Apply Warp Stabilizer onto AE Master comp.

                                                                          Now apply the Warp Stabilizer effect to those clips that need it.
