Bottleneck = source

• Find bottlenecks

  Hello, I have an interesting question that I hope someone can shed some light on. First of all, my system specs.

  Intel i7 - 3930 k six core (no overclocking yet, just Turbo Boost that I just finished this build a few days ago).

  16 GB of RAM (1 600 Mhz, CS8)

  256 GB Sata III SSD project AE, AE disk cache, files and the source (two videos 1080i on this project) files

  128 GB Sata II SSD for the OS and programs (no games, just AE, prepro and MS Office)

  500 GB Sata II HARD drive for files of the effect (explosions, smoke, sound FX, etc.) But none of them are used for this project)

  NVIDIA GeForce GTX 460 SE (1 GB VRAM)

  Windows 7 64 bit

  AE CS5.5

  The clip that I made is 10 seconds long and has two layers of 1080i AVCHD videos, 1 layer of rotoscoped for the complete 10 seconds, finesse of colour, keylight, some static base masks, and I export for H.264 bluray on my C drive with the Sata II SSD, which has just the program files and BONES.

  Now the question. My problem is that none of my hardware is maxing out. The CPU's bouncing between 50% and 73%, my disk cache and the file source Sata III SSD is only transfer about 10 to 20 MB/s (capable of sustained reading 520 MB/s and all written 505 MB/s), my Sata II SSD when I export to bounces around only 2 to 5 MB/s, only about 6 of the 12 GB of RAM , I booked for multiprocessing AE is used, and my use of the video card is bouncing around 40 to 70%. I don't know what else to check. My SSD is little used and everything else is only reached about 70% of its capacity.

  Does anyone have an idea on how to determine whence my real bottleneck?

  I saw a few posts about it, years ago but it ends up being a bottleneck of the video card and the other was solved by changing just the output format (probably another video card problem). In my case, the use of the video card MAX for the duration to make is perhaps 72%.

  And not that this information is very useful, but the rendering time is around 11 to 12 minutes to complete the second clip 10... It might be useful to know that just load the second 10 clip entirely into RAM for a RAM preview only takes a few minutes at full resolution, maybe 3 minutes max.

  Thanks in advance for the help!

  You use the temporal effects / features (Rotobrush) forcing AE return to the only multithreaded treatment and you are out in a format clip requires a strictly linear progression. You can see the best performance using image sequences, but the part on the sticks of effects. In addition, there is not much to say - you will never see full use of 100% on everything. AE takes what needs it and what fits his logic, but not less and not more. And your RAM Preview proibably makes simply faster, because she is at reduced resolution or use the GPU, which will also not be used for the final rendering. Everything is perfectly normal. Simply adjust and you plan accordingly.

• Bottleneck in bulk updates/inserts

  I worked on doing updates in block and inserts through sqlapi ++ using a library of extention udpate in bulk developed internally long ago. The oracle database is. Inserts/changes in bulk are in batches of 50K. I am facing a problem of very specific performance with respect to these bulk operations.
  
  The first batch of insert in block (50K records) is done within 3 seconds; While the next similar batch for bulk insert or update (50 files again) takes a second huge 373. 'Top' on a RHEL-AS-4 server using, I could see what the oracle process that includes all of the 373 secods for completion; so sqlapi ++ or the in-house name extension isn't the culprit.
  
  The third batch of 50K records in the sequence take much longer (second 913). The time will increase exponentially; and it doesn't seem to be > all < model out of it.
  
  Surprisingly, this is not consistent. On a good day, I have the second batch browsing in 3 seconds. All the documents intact and perfect without any kind of defect in the data. In fact, all of the following prizes would end in or about 3 seconds.
  
  Even more surprising, if I truncate the table and begin the process, the problem will reappear. He would again begin taking 370-380 seconds for 2nd batch. Once again, if I had used "delete from ' query instead of 'truncate table' query to delete all records from the table, there is no problem!
  
  So in short, I came to the conclusion that the bottleneck occurs when the table is truncated (or is created new), and not when all records are deleted using the query "delete from.
  
  All guess why it could be produced? I admit that I am not very good in data bases, so any help would be much appreciated.
  
  Thanks in advance.

  Well, I ran the SPÖ in bulk a new with statspack snapshots before and after the operation. as suggested by Jonathan, used the old hash value (for the operation of your time UPDATING) of the statspack report for sql_id and prepare the execution plan. I could of course.

  Then I recompiled the program to generate the behavior that is 'good '. has run the op in bulk, statspack report generated. and surprise... There is no UPDATE statement in the report. UPDATE was simply not fired by the server; While in the test program, the rows affected by UPDATE operations have been exactly the number of lines in input (which is just, according to the supplied input data). so now it seems that somehow the server decides not to trigger the UPDATE, but still (rightly) returns all the rows as rows affected.

  While I understand that statspack report contains not all queries fired; If the correct entry, to INSERT to get me fired, is fed, the op of the INSERT, which takes considerably takes less time the UPDATE operation, finds its place in the report. so I think that in the case of UPDATE, the UPDATE query is not triggered, and so 'good' behavior reports 3 seconds, while 'bad' behavior that triggers the UPDATE reports 440 seconds.

  Note
  -----
  - dynamic sampling used for this statement
  

  It seems that I did not yet understand the logic of your 'server' process, but if this seems to be a reasonable explanation to you that, in the case of the 'good' performance update is not performed at all, then this might be the point.

  But looking at the execution of the UPDATE plan you don't think it might be better to accomplish the UPDATE using an index? Is there an index on the parentmemberid columns, the childmemberid and the parentdimid of MDS_MEMBERRELATIONMAP?

  Moreover, it seems that you have no statistics at all on the MDS_MEMBERRELATIONMAP table because the optimizer using dynamic sampling, which takes some time to run because the optimizer runs a query on your table using predicates to check the cardinality in the analysis of the declaration.

  I already mentioned that the execution of a single update requires that an average of 22 000 block gets by executing the statspack report you posted previously. Which is probably due to the carried out full table scan. If the three predicates parentmemberid, the childmemberid and the parentdimid only identify a few rows (or may be even one), then it is probably much faster to have an index suitable for the execution of the update.

• Retiming does not not on surround sources

  I have a problem using logic to reprogram cinema surround sources. I use Pitch' no time did a great job of Retiming of mono and stereo sources and working happily in ProTools, which we don't have.

  But once a surround source is used in the logic and a speed control is composed, (such as-4% for the 25 > 24 fps Retiming) rebound resulting is the same in time to the source. This occurs using NTP and also one of the algorithms. Nothing works except mono tracks, which destroyed the Retiming of split engine block beautiful phase.

  Anyone else had this?

  In fact, I'm wrong - or perhaps in law in a different way - it seems to be the choice of Surround sound in the bounce dialog box that fires it upward, regardless of the source.

• Change the source of entry with the Caps Lock key does not

  It should be possible to change the input source with the Caps Lock key on macOS Sierra.

  and I checked "Toggle ABC of input source with caps lock shift" in system preferences > keyboard > input Source.

  However, it does not lock shift still only works as long as CapsLock

  I tried to reboot, reset the keyboard shortcuts, deactivation of Siri, reset NVRAM and reset the SMC, but still does not.

  I use only the default input source and have not installed and related programs to the keyboard or input source.

  Can anyone help?

  Thanks in advance.

  Greetings slwsbl!

  Thank you for using communities of Apple Support.

  I see that you want to change the input source with the SHIFT key on macOS Sierra. I understand the importance of wanting to use a specific key when changing inputs. I'm happy to help you with this.

  It is possible to do. Please take a look at the User Guide helps Mac, specifically, this section:
  
  

  Switch between input sources

  To switch between input sources, do one of the following:

  • Use the menu entry: Click on the menu entry in the menu bar, and then choose the input source. If an input source is dimmed, the current application does not support it.

  • Use the Caps Lock key: Press the caps lock shift key to switch between a non-Latin input (such as the Chinese or Korean) source and an input source Latin (for example, French or English).

    To use this method, you must select the option "use Caps Lock to toggle to and from" in the stream of input methods. Choose the Apple menu > System Preferences, click keyboard, and then click input methods.

  • Use keyboard shortcuts: Press control-Option-space bar to select the source of the following entry in the menu entry, or control-space to select the previous input source.

  Best regards.

• Music source

  I always play music and message people on Viber simultaneously, however after the update to iOS10 as soon as I press on send a message of Viber music vanishes and Viber becomes the source of music.

  Please let me know if there is a solution to this.

  You have sound notifications enabled for Viber? Maybe disable this option will help you.

• Change the audio source

  I have some hearing aids Starkey that my iPhone 6 passes to for a phone call.  Since iOS 10 has been installed, it doesn't seem to be an easy way to stop the streaming so I can put off the phone to someone to hear it.  I used to drag up from the bottom and he gave me the opportunity to move to phone audio, speaker, or hearing aids.  This possibility seems to have disappeared.  Any suggestions?

  Still, you drag to the top of the bottom, and now there are two options, you will need to slide from right to left to the option of audio source.

• Can what audio sources I use in iMovie?

  In iMovie, can which audio sources I use?  I find that only iTunes songs appear.  Can I use music from a CD?

  In addition to the iTunes music, you can use several common digital audio files as AIFF, MP3, AAC, Wave etc by drag and drop in iMovie. Griffin Technology makes a device called iMic which digitizes audio and connects to your Mac. It is a good solution to connect to your CD drive and scan the audio output digital file and send to the Mac. They also include scanning software. It costs about $50 and is a great way to get your CD, turntable, radio audio in iMovie.

• Make a movie with clips of 1080 and 4 k sources

  Hi all

  If I do a movie with clips of 1080 p sources (like my iPhone 6) and 4 k sources (like my GoPro) I'll still be able to export the animation to quality 4 k? Is there something specific I need to do to keep export k 4 option in iMovie available i.e. the order I add clips in the project, etc.? Will be 1080 p "blasts upward" clips at 4 k resolution?

  Thank you for your help.

  Miles

  10.1.2 iMovie will use the size of the first element that you add to your project to determine the format of the exported movie.

  See Help: http://help.apple.com/imovie/mac/10.1/#/move6ccb3330

  The resolution and the frame rate of your movie project are determined by the first clip you add to the timeline. iMovie now supports 4 K video and image rates at 30 frames per second (fps). If you want your project to be set at 4K resolution, the first clip you add to the timeline should be a clip of 4K. If you want your project to be set to 60 fps, the first clip you add to the timeline should be a clip of 60 frames per second.

• MISSING OBJECTS IN THE IPHOTO SOURCE LIST

  1. lack of points of the iphoto source list such as: places, trash (I have all of the photos, last import, Favorites, videos).  How can I restore what is missing?

  2. under iphoto events are lists date of the photos.  However, the only ones that have a picture on the tile are in 2014.  I 2015 dates shown with a blank tile left and I have none for 2016.

  3. I have dropbox, but my photos are not synchronized with all my devices.  My iMac has all the photos, but each of them does not flow to my macbook.   There is partial proof of 2014 and 2015 photos in the macbook (so some transferred) and all to see the 2016.

  4. when I click on a photo I do not get the arrow pointing down to the context menu and I don't have an icon or anything to click for editing.  I can rotate.

  Help!  What is my problem?  Thank you!

  1. to begin, we need details - what version of the operating system and iPhoto do you use?

  2 - explain that statement in detail

  If your iPhoto library is being synchronized by using DropBox is your problem - you can not ever do this - that the iPhoto application can be used to change the iPhoto library - if you put on DropBox and sync, it you destroy

• for debugger, shortcut moves keyboard focus to the component source from research

  I'm in the debugger and use the search function to find a definition of the function by pressing ctrl + d. I select the function definition.
  It works great so far, but the focus of the cursor is always in the search window. In general, I now want to set the focus on the source pane (so I can scroll, set breakpoints, etc.). However, I can't find a shortcut to the source window. Y at - it a shortcut or other quick way without using the mouse?

  Thank you

  I couldn't find a shortcut or the other, then maybe suggest to add such a feature.
