After Effects uses a lot of memory (live RAM) when you perform simple work

Hello

When I open AE, make a new project, import a simple 20 MB mp4 file itself and start playback of the clip (RAM Preview), consumption of RAM of After Effects gets up to 5 GB, and the CPU usage gets up to 50%!

This is a really simple job, and I don't know why it takes so many resources, it wasn't happening to me before.

I'm on Windows 8.1, I use After Effects 13.2.0.49 (2014.2) and I have 8 GB of RAM.

Why is this happening?

Thanks in advance.

MP4 are notoriously calculation-heavy because they are so heavily compressed.  What explains the treatment part.

RAM previews allow AE to use so much memory that it has to play in real time.  What explains the part of the memory.

  • After Effects uses a lot of RAM

    Im a bit new to after effects, but I know my way around. My problem is that I have a file FRAPS 1.2 GB I want to add some effects, but after he added into the computer and clicking on preview, I get about 15 seconds of good video but after the green bar made just goes. My look at the use of mu ram and 15 seconds on the ram 11FR spell. Why does this happen?

    The file there 720 p and 32 seconds long and 1.2 GB spell, shouldn't the ram so 1.2 GB file? Ram im using is corsair 1600 mhz ddr3 4 gb x 4 revenge. IM also using CS6.

    The FRAPS codec creates a compressed video file.  After decompresses video effects in order to treat and it stores this video in a form uncompressed into RAM for an overview.  That's why your smaller file grows to a large amount of RAM required for previewing.

    After Effects does not play long video stream in real time.  The RAM Preview aims to build segments of a short preview to check your work.  To view the long segments, make a file of the rendering queue.

  • After Effects using 5 GB of ram for the preview of a video 12 MB in size without any effect.

    I after effects CC 2015 to date.

    My terms of reference are:

    CPU: i5 6500 3.2 Ghz

    8 GB of RAM: DDR4-2133 MHz RAM

    Storage:256 GB SSD (on which After Effects is installed)

    1 TB HARD DRIVE

    Graphics card: GeForce GTX M 970, 6 GB

    All the drivers are up to date.

    The problem is: I create a new project and import a video in. The video has a full HD resolution and is 12.5 MB in size. First of all, it takes a minute to play the video of RAM so that it begins to play in real time. Then, the video is 30 frames per second, but reading the preview, he plays at 60 frames per second (frame rate is defined as 30 fps in composition settings). I saw the RAM usage in the Task Manager and After Effects using 5 GB of RAM. Then I applied an effect and the CPU usage rose to 100% and it took about 5 minutes to get the applied effect, and after that, After Effects crashed.

    I'm quite new to After Effects, but I'm also a tech geek. I tried to play in the settings but it didn't help. I also searched on google and forums, but to no avail. This problem is essentially what makes the software unusable for me. Please HELP!

    You do not want to edit long movies in AE. After effects is NOT video editing software.  A non-linear editing (NLE) like Premiere Pro is for editing photos to tell a story. AE is for compositing, Visual effects and graphic cartoons. It is for the creation of clichés that you then use in an NLE.

    I suggest to get at least 16 GB of RAM to work with AE, but your system should work as it is. You will need to learn to manage your memory well and to get a glimpse at lower resolutions where possible.

    Now, as to your original question. AE is not simply to play a video stream, as does a NLE. After effects (such as other software based compositing on pixels) with completely decompressed frames. When you put a video compressed in a composition, the size of the original video file has no effect on the size of the images that works with After Effects. After effects unpacks this video and works internally with a full, uncompressed resolution, frames. AE calculates the values of each pixel in each image, comes with a new pixel and then reads these pixels. Who is?

    In fact, since you have so little RAM and the processor is not either, it may be a good idea to convert your video files highly compressed in a good intermediate codec for the shots, that you intend to use in AE. QuickTime with the PNG codec would be a decent choice. This way AE doesn't have to do a ton of work to decompress images behind the scenes until you can even work with him.

  • Flash player 11.3.300.262 is using a lot of memory

    Since the update flash a few days ago, that the plugin uses a lot more memory than usual. He uses normally between 150 MB to 200 MB, but now I've seen him use up to 900 MB.

    I noticed that the memory use increases of 5 MB or more, when you browse through a video until I stop the plugin because of the ridiculous amount of memory used.

    Please check if all your plugins are up to date. To do this, go to the Mozilla Plugin Check site.

    Once you are there, the site will check if all your plugins have the latest versions.
    If you see in the list of plugins that have a yellow button to update or a red button update now , please put to update these immediately.

    To do this, click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps in the installation process.

  • I would like to know what svchost processes I can disable and how. Some of them use a lot of memory on an older machine making it almost useless .___Thank you, ___Ray

    Some of the processes running in the Task Manager use a lot of memory in an old machine (laptop), and the amount of additional memory that can be installed is very limited.
    I would like to disable the process I do not always use or need and speed up things a bit.

    http://aumha.org/a/loads.htm - which loads at startup?
    http://www.theeldergeek.com/services_guide.htm
    http://www.blackviper.com

    Some reasons for the slow pace of the computer:

    1. computer has not been maintained - http://www.elephantboycomputers.com/page2.html#Maintenance

    2. the computer is infected with the malware - http://www.elephantboycomputers.com/page2.html#Removing_Malware

    3. the disk is too full. Remove useless stuff, uninstall unused programs. Do not forget to save!
    http://www.elephantboycomputers.com/page2.html#Backing_Up

    4. flaky third party software. Toolbars and modules are particularly guilty in this area. Uninstall toolbars (Google, Yahoo, ISP brand, etc) and look at what modules are in use in your browser (s).

    5. computer has too many unnecessary programs/processes running in the background. Manage your Startup:

    For XP - How to troubleshoot using the Msconfig in Windows XP utility - http://support.microsoft.com/?id=310560
    The free Autoruns program is very useful for managing your Startup - http://www.microsoft.com/technet/sysinternals/default.mspx

    6. the user runs an inflated/invasive such as Norton and McAfee antivirus program. Replace it with a better program. I recommend NOD32 (commercial) or Avast (free). Avira is also good, but the free version has an unpleasant reminder screen (Google for instructions on how to disable it). The user can also run several real-time antivirus/firewall/security programs.

    7. the user has installed new programs that are processor and/or memory-intensive (Photoshop, AutoCAD, Mathmatica or similar) and does not have the power of the equipment.

    8 drive fails and is in PIO Mode. It's very much slow (like being in 1985). See Hans-Georg Michna here information - http://winhlp.com/?q=node/10

  • Can not browse the Presets of After Effects using bridge

    Whenever I try to browse the presets in After Effects using Bridge, a warning notification appears saying bridge to not installed when I installed it well. So I try to uninstall it and then installed it again and it still doesn't work. Help, please.

    Hello

    We published a new version of Adobe Bridge (CC 2015) on July 19, 2016. This update is available via the Adobe Creative Cloud application.

    We addressed some launch bridge issues experienced on the launch of the After Effects application. Please try the new version and look for problems you encounter.

    If you are not able to locate the bridge (CC 2015) on the creative cloud application, you will need to update the creative cloud application and restart your computer.

    Thank you

  • My XP guest uses a lot more memory on the new laptop

    I just got a Dell Studio 15 and moved my Windows XP VM to it, and it uses a lot more memory than on my old system.  I don't know how VMWare allocates memory, but on my old system, I saw almost no additional memory used when you start this virtual machine (with the exception of the cache memory), but on the new, it uses almost as much memory that I have assigned to the virtual machine (1024 MB).  It is also worth noting that I use VMWare 7 on a new and 6.5 on the old host.

    Anything I can do to get great efficiency that I was getting on my old system?

    really not use 2 virtual processors on a host that has 2 CPUs.

    What is an Ubuntu 9.10 system?

    Other than adding

    mainmem.backing = 'name '.

    for the vmx file.

    This will slow down the virtual machine, but you wanted to do that ;-)

  • the process Svchost.exe to netsvcs uses a lot of memory (~ 600 MB) and 100% cpu

    I have windows xp edition sp3 family. I hit the power button to hibernate the pc but I think an automatice update was running.  Pc crashes when windows resumes after hibernation. I forced a re-boot, but now the svchost.exe to netsvcs process uses a lot of RAM and CPU. I have a Dell Dimension 8250 with 1 GB of RAM. Svchost uses > 600 MB of memory and 100% of the CPU unless I have stop the DHCP service. When I stop DHCP the svchost stops using CPU and memory affected slowly decreases to about 150 MB and remains at this level. But without DHCP I do have access to the network.

    After installing SP3 recently I started having some weird problems, as I lost my printer and had to re - install the software. Also noticed that after re-booting and desktop appears completely empty, the screen turns white and the taskbar at the bottom will appear empty for about 30 seconds, then reappears. PC seems to be more slow tha before installing SP3.

    I've tried everything. Nothing stopped the svchost to chew all the memory, virtual memory and time processor. Had to re - install windows xp.

    original title: scanning for dell studio 1737 and recommended bios update

    Hello, generally, I read until I have my answer, but I can't so I think I give it a try. Somehow I screwed things up with my computer. My main complaint is that I have something running that takes a lot of memory according to the Task Manager. My fan runs often, 1-1/2 minute stop time, pop up messages telling me to stop then reload IE9 sp2. I found some stuff on my event viewer, but I can't seem to cross the first error which is something on my bios. I go to the dell website to try to update with a flash of the bios but note comes up saying that my computer does not accept the flash. I have other issues in both event viewer, but can't remember them that I can't get beyond the the bios issue. The computer is a Dell Studio 1737 plenty of core duo memory 4 MB with plenty of space on hard drive and it seems to do well but all the * running in the background makes it run hot so the fan. All I want to do is get a scan for my installed bios system and install an updated version. I am not able to do at Dell. Maybe they want me to pay to support or something. I did all the FixIt of ms, I ran three different registry cleaners, I ran three viruses different scans, nothing. I've loaded my vista dell disk and tried to recover or repair and cannot do it either. I notice weird things with ie. I've done several downloads for versions 32 and 64 bit, to do the right thing. Maybe he has an it is to say the conflict or something. Whatever it is, I'm sure it's related to the fact that my computer takes 1-1/2 minutes to stop, even if it starts normally. I played with it for about a month now and I'm traps at all reading. If I can Flash my bios and get this update, maybe, I'll be able to get then some of the other things go. Here are some tips from the event viewer if anyone has any time for her. $ 1 million for any help thanks! If anyone knows where I can find a site that can digitize to my existing configuration and then recommend the installed updates. Oh, just in case anyone is wondering why I do not pay just for a few servieces for help me, or take it to a computer store, I don't have a job and can not afford it. Believe me. I have many errors saying: the embedded controller (EC) has failed in the specified time-out period. This may indicate that there is an error in the EC hardware or firmware or BIOS is accessing the EC incorrectly. You should check with the manufacturer of your computer for an updated BIOS. In some cases, this error may cause the computer to function properly. And The Office Source Engine service entered the stopped state. Service WinHTTP Web Proxy Auto - Discovery Service entered the running state. The Google Software Updater service entered the running state. The Google software update service entered the stopped state. A total of 60 errors in a single day, for weeks. Thanks again!

    Ok..

    The first task manager...

    Open it and then click the CPU tab until the processes that use most of time processor are grouped at the top of the list.

    The system idle process should be at the top and then maybe three points below that seem to take the time to processort.

    Make a note of them and then look on the Internet that each fact or the program, application or process to which they are linked.

    Forget the event viewer and any reference to it in the BIOS...

    All the * running in the background will not cause it's running more hot so the fan. BUT, you can have installed something knowingly or perhaps inadvertently causing the CPU work all the time. Reference to what I said about the Task Manager. This is where you will find the cause most likely.

    BIOS... How to download and install... taken directly from the Dell support site. No payment at ALL is required. BUT, you probably don't need to do and if you do, it should choose to do so, it should be performed using socket at a time when it will present no risk of a power failure...

    Fact MS Fix - its for what exactly?

    Use of registry cleaners will create more problems than they ever solve. You may well have created one of the issues by running a registry cleaner. Uninstall them as best as POSSIBLE...

    Three viruses different scans? Without doubt completely uninstalled before the installation and execution of another? In addition, what av scanners?

    Many downloads of 32 and 64 bits, what?

    Your computer may take a long time to stop if an open e-mail program is defined on control too frequently, or if a backup utility is configured to check the differences between system and backup is too frequent. In addition, some gadgets can slow down to stop, and USB keys will cause Windows to ensure that there is no process to read/write that run to them before she stops them.

    Flashing the BIOS is not and has never been the panacea for all the ills of the computer and won't solve ANYTHING in your case.

    If you have upgraded from Vista...

    Go to the Dell support site and downlaod driver and install any Windows 7 drivers for your machine other than BIOS. If you enter your number of service on this site...

    http://support.Dell.com/support/downloads/index.aspx?c=CA&CS=cadhs1&l=en&s=DHS

    you will be presented only with the specific drivers for your machine.
