After Effects :: CC Slow Renders On IMac (low CPU Usage?)
Mar 1, 2014
i have an fully specced late 2013 27" iMac for working with the Creative Cloud Programms. At the moment i only have 8GB installed because of problems with my 32 GB Ram kit. I have an internal SSD for the OS and Programms, an 256GB USB3 SSD for Chache Files and a Raid 0 for my Source Files.
I am now rendering an 7min long movie shot on an Red Epic in 5K and 4K to an ProRes422HQ 1080p File out of After Effect. I mainly used the "Levels" Effect and an Plug-In called "Film Convert". No crazy animations or effects. My Render time is about 18 hours (it`s nearly finished, so this are no wrong calculations by AE).
Are this normal render times that should be expected when working with such large source files?What makes me wonder is that the Activity Monitor show only bout 40% CPU Usage (see attached screenshot), shouldn`t that be maxed out?I have to render out a few more similar clips.
i have the imac 27 680mx 32gb ram,when i render on cs6 takes very long time, the first one takes 8-10mins,when i do the second time its very fast 30seconds
I installed After Effects pretty much without changing anything, so the settings are more or less default. I'm using a Macbook Pro with OS 10.6.8 and After Effects CS6
I have enabled media and disk cache, max disc cache is at 100GB and I have an external drive (with 900GB spare) as the volume selected beneath that option. My internal SSD has not much spare on it. I previously had the internal SSD as the disc cache and still had this same problem.
My project is 1920 x 1080 25fps - And I'm trying to render to Quicktime. I've tried rendering to stills and then outputting to Quicktime (so as to have less computational effort), then running them through but the same problem persists.
If After Effects is the application in focus the project renders fine.
If After Effects is not the application in focus - ie. I work with it rendering in the background, the 'FINISHED' sound plays and the render is cut short a short while after I started working in another program.
The project render time is about an hour, so it's not really convenient.
My AE comp renders as a full-length video of a black screen (with audio, when enabled). Comp plays fine in RAM preview, and I've tried all types of codecs and disabling RAM intensive effects, though I'm working on a quad-core i7 macbook pro with 8 gigs of RAM, so that shouldn't be a problem.
I have been faced with an almost identical problem listed here URL....The only thing that changes it from complete blackness is the "Ambience" value. I've done all software and hardware updates, reinstalled the graphics card driver, and restarted a multitude of times. I am using:
Dell Optiplex 390 Intel(R) HD Graphics 2000 Windows 7 64 bit Photoshop CC No Color Management No plug-ins, or anything other than default PS settings
I used Lighting Effects on Photoshop CS3 and CS6 for almost two years on this machine with no problem. This was the first time I had tried to use it since I upgraded to CC. I uninstalled all other versions of PS when I upgraded, so I have not tried to replicate the problem in older versions.
I've just installed photoshop cs2 and every time I go to use the brush, my cpu does some major laggin. I've opened task manager while I begin to draw, and right when I start, the cpu usage shoots up to 100% usage. My specs are:
i have a certain tv-promo-project where i have to render several comps which all include the same amount of text and just a hand full of additional graphic elements, e.g. a lensflare and a glowing line which separats the text blocks.
The text of the specific promo-comps are read out of a "main text comp" by expressions. The expression is as follows:
The rendertimes of the project are constantly slowing down as the render queue and the process goes on. The first comp takes about 8 Minutes to render (it is only 10 sec long) and the second already 20 min, where the third comp reaches like 2 hours of render time. I also recognized that even the preview in the timeline is really slow, although the used effects are usually not that performance heavy.
The thing is that I recently bought a new pc workstation w/ the following specs:
32 Bg Gigabyte Motherboard - Intel i7 hexacore 4930K 3,4GHz w/ hyperthr. (12Mb Cache) NVidia GTX-780 2 x Kingston HyperX 3K SSD 120GB - raid for OS and apps 1 x Kingston HyperX 3K SSD 120GB - as AE's dedicated Scratch disk 1 x Western Digital WD20EZRX 2 TB - as storage Windows 8 / AE CS6 11.0.2.12
Previews: - Adaptive Resolution Limit: 1/8 (Ray-tracing on CPU since my GTX-780 isn't in the list) Viewer Quality: Zoom Quality: Faster Color Mgmt Quality: More Accurate Except RAM Preview Alternate RAM Preview: Preview: 5 frames
Media & Disk Cache: - Disk Cache enabled (max. Disk Cache Size: 100 Gb) - set on AE's dedicated Scratch disk - Conformed Media Cache: Database & Cache - also set on AE's dedicated Scratch disk
Memory & Multiprocessing - Installed RAM: 31,0 Gb - RAM reserved for other applications: 15Gb (I'm also using Maxon C4d) - After Effects Multiprocessing's Render Multiple Frames Simulteneously: enabled - Installed CPU's: 12 - CPUs reserved for other apps: 6 - RAM allocation per background CPU: 3 Gb - Actual CPUs that will be used: 4
My problem now is that my RAM previews (w/ and w/o Shift) are pretty darn slow, regarding the fact that I'm working on a really basic scene now in 3D space (Classic Render), involving 1 layer w/ the Stroke effect, VCP's Sure Target 2 cam set up and 2 small precomps w/ a small folding contentframe.
To RAM preview a 5 sec take, it takes almost 10 sec to build up this little scene. When I look at the processes in my task manager, I see that as soon as I RAM preview to my Scratch disk, the writing speed is a very dissapointing 3,4 Mb/s. I take it that this is an AE issue, since writingspeed to my Scratch SSD is checked and confirmed 180Gb/s +.
I need to make a 30 second long zoom in Z space and I'm using a 3D camera for that. I've separated the dimension on the positioning of the camera so I could use only the 'Z position' to make the zoom.
I'm starting the Z positioning from 0 until -700000 (I know, It's kinda far!) But I've noticed that my images (which I've placed in 3D space so they pass the camera in Z space) are getting slower and slower because of the far zoom I quess?
How closer I get to the number -700000 how slower the camera movement is going.
The performance was fast without OpenGL(Fast Previews > Off), with my old graphic card, GeForce GTS250. After I upgrade the graphic card to Quadro 5000, it's really slow with exactly the same settings.
that is having really slow performance using AE CS6 or AECC and possibly AE CS5.5 I think i might of found out what the problem is.My System specs are below:
- Really slow performance when scrubbing along the timeline.
- Adaptive Resoltion wasn't working at all super slow previewing
- Multiprocessor rendering not working, or taking forever to start up, and sometimes it would work but still not the way it should it was hit or miss
- Disk Caching not working
- many others that I can't think of at the moment
SOLUTION for slow scrubbing of the timeline for Quad, Six and Eight core systems
Here is what I figured out after hours and hours of testing and configuring. I even went back to AE CS5.5 to see if all these problems existed in that version. Although some did but not all
From what I can tell it looks like certain plugins are not compatible to Quad, Six and Eight Core machines. The main plugin that has the problem is Keylight 1.2 that comes bundled now with CS6 and CC.
If you turn off the plugin on your layers scrubbing the timeline speeds up and works like it should. If you want to use keylight then do the following:
- under screenmatte, set the screen softness to 0
- shrink and grow to 0.
If you use any number other than these settings it causes scrubbing and rendering of the timeline to go extremely slow.
SOLUTION for all the issues above for Quad, Six and Eight core systems
After hours and hours of testing I have come to the conclusion that AE CS6 and CC don't work well with Quad, six and eight core systems in general and especially with the keylight plugin.
FIX: Go into your Bios of your computer and set your multiple core to either 1, 2 cores, theis will give you 2 thread or 4 threads. This will fix all the issues as stated below. I haven't tested 4 cores yet but soon will. But I know that 6 and 8 cores definitely does not work it causes all the major issues above.
After setting my system to 1 or 2 cores, Ae is extremelly fast and responsive. Timeline scrubbing is super fast now even with keylight 1.2 and all it's settings. Adaptive resolution now works, Multiprocessing starts up immediately and disk caching is working.
Conclusion
I am not able to set my system to use 8 or all cores in my bios, This causes so many performance issues in AE CS6 and CC and some in even CS 5.5. I need to use either 1 or 2 cores. As you might no this really sucks when I am limiting myself to only 4 threads when I could be using 32 threads. Pleas Adobe look into this issues with these systems that have 4, 6 or 8 core systems. This could possibley just be for Dual core systems too since that is what I have here.
I am working with something new in AE this week and I am curious if I am doing something wrong. I need to insert a 3D thumb tack PSD file I imported into AE with a film I am working on. As a test I just wanted to see what quailty the pin would render out for the final because the preview in AE looked horrible. So I have a static shot of the Thumb tack and it is going for 10 seconds. I started the Render and it has been going for 9 minutes so far and still shows 1hr 28 minutes left. I've rendered 8 minutes music videos in 45 minutes on this same PC.
I am using a PSD for 3D because I do not have 3D software.
Why is the scrolling on the timeline so slow when Cache indicators are enabled? It's very useful to have cache indicators on but when they are enabled the scrolling (up-down/left-right) on the timeline becomes significantly slow and unresponsive enough to make it unusable. It's more noticeable the more layers are present in each composition. It's very frustrating and it is something that started happening from 5.5 onwards.
I am now on After Effect 12.2 with a Macbook Retina 2.6Ghz i7 and 16gb of ram. The problem was also present on my previous laptop.
I am creating 3D renders in PS CS6, and I am getting strange blocky artefacts in the renders. These appear on first pass and persist throughout the render. This has happened in the last 2 renders I have tried - I haven't used 3D for a while before this and I don't remember these before.
By blocky artefacts I don't mean the JPG artefacts created by the forum's degrading of the uploaded image, but the light coloured rectangular blocks around the "s",On Win7x64 with latest PS CS6 update; NVidia 650M2GB on a Core i78GB.
When viewing the model on screen it's exposed correctly, but whenever I try and render it out it's overexposed. I have included a screenshot of the rpref.
I seem to be having this issue with rendering in Max. I play this game called SimCity 4 and have a special user-built script for 3ds Max that allows exporting models made in Max into the game after a few steps.
The script basically sets up Mental Ray and some camera/light rigs to mimic realistic sunlight. In this image you can see the problem pretty obviously.. In some areas it looks like there is coplanar geometry, and i've double checked to ensure there isn't. Some objects have complete portions of the geometry missing, such as the roof.
Whats the best way to blend renders to backgrounds? I've learned a few ways, but not sure which is best. So, two questions, is this blending and if not how do you blend? Also, this is only my second sig, I'm not looking for judging in this thread just tips on blending for now.
Uhm, whenever I render I only get white outputs. I'm used to use Revit, and have forgot how to use autocad. But this project relies on making a couple of renders in Autocad.
How do I get useful outdoor as well as indoor renders?
I am quite new to 3D modeling & rendering. I did a simple 3d model of a standing unit, but once i clicked on render, only a black screen appeared.
I did try to put a point light and increase its intensity but the model can barely be seen. I also created a new camera and clicked render but to no avail.
when I send an image from Lightroom 4.3 to Photoshop CS6 (CMD+E), it renders slightly differently. I notice Photoshop (CR) seems to not apply the lens correction profile I apply in Lightroom. Sometimes it seems the luminosity of the image too is slightly off, but updating the image preview in Lightroom seems to fix this (but not the lens profile issue). I thought it was a monitor color profile problem, but what has it to do with the lens profile correction? To me, it just seems Photoshop renders the dng differently than Lightroom.
I'm on a Mac and everything is updated to the latest release (both Adobe and OSX), so I don't think there should be a compatibility problem between software versions..
However, when I do some heavy editing, like anything that takes a few minutes of CPU processing, I tend to look at the task manager only to find that 4 cores are utilizing 50% at max thus taking longer to compute the results.
Is there a way to maximize CPU usage by Photoshop? I would like it to use 100% when performing tasks to speed up process time. Is there a windows plug in?
I am using Vista 32 bit with 4 GB ram installed ( 3gb availible ). In the Performance Settings the max. Ram allowed is 1620 Mb, not the 3gb availible. How can I use this?
how to make my photshop application fast few days ago it was working good but now its performance is slow and my computers speed is also slow. How to fix it?
After shelling out a pretty penny for Inventor 2012, my boss set me up with a less-than-adequate off-the-shelf PC. I don't need faster visualizations as I'm not dealing with super complex assemblies, maybe 100-200 parts. I also don't care about ray-tracing while modeling. My problem is it took 24 hours to render a 65 second animation (about 1000 frames).
my boss is going to allow me to build a new, more inventor optimized workstation. I am using studio to do fairly complex animations. Fades, camera changes, constraint animations, all rendered with higher quality. I need a computer that will render quickly, and possibly higher quality if available.
I don't fully understand the whole "Direct X vs OpenGL" stuff. What should I spend my money on, knowing that rendering, not modeling is where I need improvement. I am thinking AMD system to save $$. Also, what to look for, fast bus, cache, etc. Just remember, I need faster RENDERING in STUDIO ANIMATIONS.
I have these cable segments in my models. The problem I have is that when I render them or zoom out all of the work points and segment points become visible. It's only when zoomed in that they disappear.Look at the attached images for an example.I would really like my rendered videos to not have bright yellow spots.
How can I decide to have all my proxies on one location and full renders on another storage location... I can add more locations, but how to send all proxies to one location and full to another ?
