    yellow render bar in Premiere Pro CS6

    Sebastian Gross

      hey there,

       

      quick specs:

       

      HP Z820, 64GB RAM, NVidia quadro 6000 (alongside with a BlackMagic 3D extreme for monitoring), ext. SAS-RAID,  Windows 7 64bit, Adobe PP CS6.

       

      the issue is quite simple from the outside:

       

      any codec i slam into a new sequence gives me yellow (render) bars.

      doesn't matter if i customize the sequence or right click "new sequence from clip" (which i assume fits my sequence settings to my clip settings)

       

      the only codec that doesn't give me yellow bars is mpeg2. (really..?!)

       

      to check i turned the CUDA engine OFF - red bars immidiately.

      and even with yellow bars (which PP should be able to play back at least i get the choppiest playback sometimes)..

       

      but as you see it shouldn't be a hardware problem - so what am i doing wrong or didn't i get the idea of creating sequences?

       

      any suggestion appreciated.

          If in software MPE mode the timeline turns to red, it is indicative of a mismatch between the source material and the sequence setting, or it could indicate that the computer can not handle that material in real time. RED 4K for instance.

            thanks harm,

             

            i know all that.

             

            i used presets, customized and as explained earlier also used the "new seuqence from clip" default. nothing helped.

             

            but a machine like this and the latest version of PP CS6 should be able to handle simple h264 e.g.. i know it's an easy to encode/hard to decode codec, but it should go up in smoke when facing raw quadro 6000 power shouldnt it?

            in all of adobes show cases they played back multiple tracks of .r3d and .mov (h264) mixed.

             

            besides that, when i put mpeg2 in a new timeline i get not even a green bar, there is none at all.

             

            ???

              then you got the correct sequence.

              Yellow means it you do not have to render.

              Playback at full quality will probably not be in real time (but it might be).

              Upload a 264.file you are have trouble with.

                It may depend on the kind of CPU('s) installed and the kind of tuning you did. You did not specify them.

                 

                The Quadro 6000 is slower than a GTX 670 for PR, despite being around ten times more costly, so the raw power is relative.

                 

                With the yellow line playback can still be fine, depending on the system. I can have 7 tracks with the yellow line play back with limited dropped frames, including R3D material.

                  my Z820 has 16 intel xeon 3.10GHz cores. no tuning, just as delivered.

                   

                  but seriously: even FCP 7.0 managed to give me the "want to match the sequence settings to clip settings? yes/no" prompt - and there was no render needed as long as the system/software supported the codec.

                  (not to mention that i can not change the sequ-settings later on in PP)

                   

                  i sort of expect that from a 64bit system and a software that is supposed to support just that.

                   

                  a colleague of mine tested the h264 scenario on a mac with way less power - no bar at all.

                   

                  i mean: what kind of monster do i have to buy or: what are the obstacles to deal with this rather small seeming issue? "others" obviously found a way to deal with that?

                    If the codec you use is not supported in a preset, you get the yellow bar. So what? If it plays fine, then there is nothing to worry about. With AVCHD 1080p/50 and 5.1 AC3 sound you get a yellow bar, so what? It plays fine.

                      Being new to CS6 I was puzzling over this for a long time. I'm using XDCAM EX format files MP4. Drag one of these files to a new sequence item (so premiere correctly selects the correct sequence) and there is a new sequence with the MP4 in it with a yellow bar over it. It plays and edits just fine. That's the way it is with some codecs I guess.

                        hey harm,

                         

                        "so what?" is not really a term that i often use. when i encounter a problem, i try to fix it or at least push as far as i can push to get the optimum under the given circumstances. "works anyway" doesn't really cut it for me. 

                         

                        i want to understand why there's the need to render despite the fact

                        - that all my hardware and software is supposed to eliminate exactly this

                        - that other companies solved this problem years ago

                        - that adobe promotes a product that should do the job, but obviously doesn't

                         

                        and it actually does not playback fine. sometimes (=usually) the playback is choppy, sometimes the playhead jumps back to start without any reason and a few other problems i came across.

                         

                        i understand that adobe PP is not in the game as long as AVID is for example, but they claim to have a professional product (at least the name suggests it but as far as i am concerned if you really put PP to the test it tends to bend and sometimes to break.

                         

                        as much as i love dynamic link (main purchase reason) - i just can not run sensitive projects on it. or, before i do i need to understand why these things happen.

                         

                        you totally don't have to but i hope you understand my position.

                          Sebastian,

                           

                          I think you are overrating the impact of the yellow bar. Adobe uses a very simple and often mistaken algorithm to determine whether a timeline can be played without rendering or not. There are lots of faults in that algorithm and they do not take the hardware into consideration.

                           

                          Example: Simple HDV timeline is grey. Now add a single .BMP still and the timeline turns yellow. Why? Ask Adobe, but there is no reason IMO other than to blame the algorithm in use. This happens on low end machines and high end machines.

                           

                          On a low end machine the HDV timeline without stills can not playback without dropping frames, even with a grey bar over it.

                          On a high end machine a timeline with the yellow bar can playback without dropping frames.

                          On a high end machine a timeline with the red bar can playback with limited dropped frames.

                           

                          Does this make sense? Not to me, but then I did not design the algorithm, but OTOH, what does it matter?

                           

                          The yellow bar does NOT mean you have to render. See my previous link.
