    what's Up with the Mercury Playback Engine?


      One of the reasons I bought Premiere CS5.5, is the new mercury playback engine, Adobe says, that you know longer have to render your video files, and they play back smoothly.

      The first thing I did in premiere pro cs5.5, was testiing out the new engine.


      As soon as a imported my .MOV file on the timeline and played it back, it was SO  laggy. I got probably 1 frame every 2 seconds, So, I rendered out the 10 second clip which took 4 minutes, adn then added an effect, and played it back too again find that it was laggy like before.

          Is the sequence settings the same with the mov file?

            Okay, how would I do that, I noticed the I had to resize the video to fit in the sequence.

              Why use .MOV? 9 out of 10 you are reduced to 32 bits instead of 64 bits. Why cripple your environment by running in 32 bit mode when it can be run in 64 bit mode, if only you got rid of that .MOV wrapper.

                  Question for Harm....how exactly do

                  you you "get rid of the wrapper" for those MOV files from the Canon DSLR? I have tried renaming them to mpg with no difference in performance. My laptop PC is on the PPBM5 results page with a 372 total time...( i7 740 QM, 14GB Ram, 2 separate  internal Corsair F120 SSDs reading and writing  ~ 225MBs, 460m, and running 5.03 PPro). With 3 video tracks editing is difficult...I am starting to believe that to have real smooth editing of these H264 files, as was claimed by Adobe advertising, you must either have an extremely fast machine that is in the top ranks of the PPBM5 scores, or, you must transcode to an intermediate codec. If transcoding is the only answer for me, my experiments so far have been that mpeg 2 in AME has been the only codec which provides a smooth edit with 3 video tracks. If there is a way to "rewrap" the existing MOVs, please tell me exactly how to do that. I am guessing that even with my i7, ram, fast SSds, Nvidia, etc. it is still not enough horsepower to handle these MOVs natively....as Adobe claims it would. You need a desktop with a heavily overclocked CPU and  RAID disk setups at minimum....portable editing will be tough, unless you transcode. Thanks for any help you may be able to provide.

                    Quick check. Open your project. Kill the process 'Adobe QT32 Server.exe'. If you can still scroll through your timeline, perform editing and all works as expected, then your .MOV wrapper is not the problem (the 1 out of 10 chance), but if you can't edit anymore after killing the process (9 out of 10), it means you are dependent on the 32 bit environment.


                    In the latter case Google for a converter that rewraps your .MOV into .MTS or similar.


                    I looked up your results and for a laptop, these are pretty good results, but the problem is that your source material is H.264 and the H.264-BR score is your weakest point, showing the relative weakness of the 740QM, especially in terms of clock speed.


                    If we were to port all the entries since 2011-01-29 (303) to a new database structure, you would end up around position # 140 in the overall ranking. That is very decent and quite respectable for a laptop.

                      Thank you Harm for your response and also for the huge amount of info and guidance you have offered on these forums. I killed the Adobe QT 32 exe process and was still able to edit as before. I have found that I can edit smoothly with three video tracks of the Canon MOVs and a couple of GPU supported effects as well if I lower the playback resolution in the timeline monitor to 1/2, or, 1/4.

                         It appears , like you noted to me, that my CPU, the i7 740QM, is just a little shy of the horsepower needed....at full resolution task mgr. shows the CPU as hitting 98-99% as playback stutters, but, at 1/2 resolution it drops to between 60 and 80%,( and no stuttering, with smooth scrubbing even using the "forward-reverse" lever).

                      At the time I bought this laptop, the faster Sagers with  the 9xx CPUs were way,way, more expensive and I had to go with a portable solution, as I travel constantly. I also was excited by someone on another forum who has successfully overclocked the same laptop as mine from 1.73 up to 3.5Ghz in a stable manner and good temps using "set FSB", due to the very good cooling system in this particular Asus G73, ( which is sold as a "gamers" laptop). Also, one vendor sells this laptop with a guaranteed "redline" overclock of ~ 15 to 20%. I am tempted to try and overclock the CPU to get better performance, however, I am concerned about the" Windows Clock" issue and the possibility of corrupting data in the ram, as the base clock increases, which could get sent to my OS SSD and possibly corrupt it, ( would 1600 ram help here ?). I would be curious as to your thoughts on this and if it would be worth trying....if it would be possible,I could get the performance of an expensive Sager at half the cost !!! Thanks again!
