After Effects :: Where RAM Cache Disappears As Soon As Playback Stopped
Dec 4, 2013
I've been having an issue where the RAM cache disappears as soon as the RAM playback is stopped. Just to be clear, I'm referring to the green indicator along the top of the timeline so you know which frames are cached. This happens on various computers in our facility. It seems to be more common when multiprocessing is enabled. It also happens if you tell After Effects to RAM preview and then switch to another application. After Effects will complete rendering the RAM preview in the background, the icon will bounce in the dock to let you know it's ready, but nothing is cached when you switch back to After Effects. This is something that I've noticed for a couple of years over multiple versions of After Effects both at home and at the office. It seems to happen fairly consistently with specific comps which makes me wonder if it's related to any of the effects that have been applied in that comp.

Every now and again and usually after a crash, when I start up AE I get a message saying that the AE media cache folder does not exist. When I check on my drive for that folder, AE is quite right - it is not there. I use a separate SSD for all my media caching and another drive for footage and another as my start up drive. I set AE to use a folder called A:AE Cache. For whatever reason AE is deleting this folder. Other folders on this drive remain as they are. Unless I have a goblin sneaking into my suite on a night deleting this folder or Windows decides to delete this folder all on it's own then it is almost definitely AE that is doing it.

I am running W8 with i5 3350 and a GTX 640 and 20GB of 1600 Mhz RAM (all at default settings). I am using AE CS6 11.0.2.12
I am using a dedicated 256 SSD for my cache drive------i.e. the ONLY thing on that drive is the AE cache information. I have allotted different sizes in the cache preferences, from 140- 220GB (The drive has 240GB free space when formatted).
The problem is, that no mater what the size of the cache that I try, if there is less free space on the drive than what the specified cache size is I will get the error
"your disk cache folder is on a drive that does not have enough available space" when opening After Effects.
( 240GB formatted capacity)
160GB of cache specified in preferences + 100GB of information currently cached on drive = 260GB = The error message upon opening after effects
160GB of cache specified in preferences + 60GB of information currently cached on drive = 220GB = No error message
I do NOT get the error if I make the cache small enough, or delete the cache before opening AE, but that completely destroys the purpose of the cache in the first place.
With that, I have two questions:
1. Is there a fix for this that tells AE to cool its jets a little and recognize that the information on the SSD that is taking up space and making not enough space available is AE's own cache information?
2. If the answer to (1) is no, then is this an error I can just ignore without any major issues?
Right now it seems that this means that I can only make my cache<50% of the total formatted capacity of the drive, which seems a bit over zealous.

I recently purchased a LaCie external SSD solely for the purpose of storing my After Effects disk cache. The SSD connects to my MacBook Pro via Thunderbolt.
When I check the info on the SSD, it says it has 254 GB available, so I set the maximum disk cache size in AE to 200 GB, and created a folder on the SSD for the cache. Then I pointed to that folder in AE as the specified disk cache folder.
When I relaunch AE, though, it tells me I don't have enough space in my disk cache folder to accomodate the 200 GB max I set, even though I have 254 GB free on the SSD when I check.
Does this have to do with me creating an empty folder on the SSD to house the cache? Do I have to just use the root folder of the SSD to make use of all the available space?I just found out AE doesn't even let you use the root of a drive as the cache folder, so that can't be the problem..

When i open up after effects i get this warning "Your disk cache folder is on a drive that does not have enough available space to safely store the full amount secified in your preferences. please make more space available or go to media & disk cache preferences to change the folder or maximum disk cache size" I think this is slowing up my whole suite. I clear my disc cache folder all the time and i still get this warning. How can i fix this? Also this is a 2 part question if it can be answered i think it may have to do with the first question. When i try to add a cross dissolve in premiere pro i get this "insufficient media. this transition will contain repeated frames" .

I have an SSD disk which has 20 GB of free space that AE uses for cache, and it gets full quite often and I have to empty it every ~4 hours.
My question is can I assign a secondary location for cache for AE to store the cache files and access it from there? If I can't, is there a big difference in working speed between SSD & HDD disks regarding AE cache? (I have 2 TB of free space on an HDD disk that I can use for AE cache).
Additional info.

After Effects CS6: Cache and Reload Footage Problem
I am having trouble getting my footage to update in an AE project.
In an existing project, there is an image sequence in a composition. I have saved and closed AE, modified the footage (same dimensions and qty. of frames, only the pixel data changes), and then re-launched AE and opened the project. Though I have changed the footage, the old content still appears. I have done the following:
Edit>Purge>All Memory
Edit>Purge>Image Cache Memory
Edit>Preferences>Media & Disk Cache>Empty Disk Cache[code].....
None of these got the footage to update. I could double-click on the footage in the project bin and scrub the play head and the old footage was still displayed.Finally I had to replace the footage with itself and that resolved the issue.
If this is operator error, lack of understanding the cache functions, or something else. I don't recall this behavior in CS 5.5, so I am guessing this is a change in CS 6.
Win 7 Pro 64bit Service Pack 1
Intel Xeon CPU X5450 @ 3.00 GHz 2.99 GHz

"After Effects error: RAM Preview needs 2 or more frames to playback."And I have searched this entire forum about a solution but nothing worked.I have been in Preferences-> Memory & Multiprocessing and adjustet the settings.
I have tried PURGE all memory. Uninstalled After Effects CS6. Installed again with update 11.0.3.6 .....and still the problem occurs? I have fought with this error since I installed After Effects CS6. As you can see my computer have enough RAM and CPU power.

Today I got a SSD just for the cache in AE and set the preferences. I changed the "Disk Cache" to the new SSD and then also changed the second option "Conformed Media Cache" to the new SSD - then watching some videos I noticed others have only changed the "Disk Cache" and left the second option as c:users ameAppDataLocalTemp. I tried to put the second option back, but when I browse for the folder within the preferences framework I cannot see it. Deleting the preferences didn't alter the Conformed Media Cache as set by me today. I changed it today thinking that the new SSD has more space than my c drive which is also an SSD. My questions are, can I leave the conformed media cache on the same drive as the disk cache? If not, can I just make a folder on c drive under users and use that? If neither and I need to reinstate the default folder, how can I see that through the AE preferences dialogue box?
My setup is an i7 3820 with 64gig of RAM, programs running from a SSD, another SSD just for the cache, standard modern hard drives that keep my assets from my project files and another for finished and rendered items. My GPU is an Nvidia GeForce 560 and I have added this to the list so AE uses it.

I have installed After Effects CS6 in a Mac running 10.6.8(Snow Leopard) with 4 GB ram and have installed all the updates of After Effects. Whenever I try to get the audio output, i get an error: " After Effects Warning: Unable to start audio playback. confirm your audio hardware is properly configured or change the driver selection in Preferences: Audio Hardware "
I tried to reinstall the software and also I tried the Audio MIDI Setup configuration but it too is of no use.

I am using a Lumix GH3 camera and recording in .mov at 50fps progressive and 50mbps. My computer is a macbook pro two years old with 2.2ghz intel core i7 and 8gb of ram (1333 MHz DDR3).
The footage plays fine in the editing suite until I add an effect then the playback is extremely slow and jerky even after render. I am new to PPCC and I've just moved from FCP 7 as it didn't recognise the footage at all.

This issue started out of nowhere for what I consider to be no reason. Working on average sized 720p compositions with modest animations.
I am running fresh comps in AE CC with absolutely no plugins, freshly purged memory, cleaned cache, restarted comp, no other applications running on computer and 13 gb of memory allocated to AE... etc.

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:
Dell T7600 Dual XEON E5-2687W 3.1/3.8GHz w turbo / Dell M6700 i7 -3940XM 3.9GHz
64GB Ram / 32GB Ram
Nvidia Quadro K5000 / Nvidia Quadro K5000M
Windows 7 x64
Here are the issues I was having
- 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.

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'm new to Premiere Pro CS6,I thought I had a pretty powerful computer all things considered. Basically, what's happening is the moment I put any sort of basic video effects on a clip, (e.g. "brightness & contrast" or "fast color corrector") the video playback (but not the audio) becomes extremely choppy and laggy. Playback and overall performance are excellent before I put effects on. It's just the moment I put some on it slows down tremendously.

When I turn a layer into a 3D layer it disappears. If i turn draft 3D on it will reappear, or if I preComp it will reappear. continuous rasterize is not on so its not that. Active camera is set in preview window, so its not front view thing.

I'm running into a problem whenever I use multi frame rendering in the ram preview. If the machine is rendering and I don't have After Effects as the active application or whenever I stop playback of the ram preview, the cached frames are immediately deleted. I can see the green line moving forward as the image is rendered, but the second I stop the preview (or if AE is rendering in the background and I don't click back to it in time for it to begin playback) then the frames are gone and the green line disappears and I cannot scrub through the rendered frames.
If I disable multi frame rendering, then the green line and the cached frames remain in the preview window, and I can scrub through them like normal; they do not clear. Only when multi frame rendering is enabled does it disappear after render.
I know the frames are saving, because I have 32 GB set on my SSD for the disk cache (I also put them on an external HDD to test with the same results). It will fill up that 32GB of space presumably with the cached frames that disappear after render, but they are not accessible. I also have 16GB of ram, with plenty free for AE to use for caching (3GB per core = 12GB set for AE ram preview). I have not had this problem of the frames clearing until AE CC.
The only thing I can think that would be different from other times when I've not had this problem is that I'm using ProRes 422 (LT) clips in the compositions. But I don't know why they would cache normally without multiframe and then be immediately deleted with it enabled.
And no, rendering without multiframe is not an option. RAM previews take four times as long with single frame rendering, and I don't want to sit at my computer all day waiting for previews. This is extremely frusterating, as I must have AE open as the foremost program at all times. If I miss that crucial moment where the render completes and click back to the program a second late, all the frames are gone and I must rerender again! It happened twice while writing this message.
So what's the deal?
Specs:
AE CC 12.0.0.404
Retina Macbook Pro / OSX 10.8.5
2.6Ghz Core i7
16GB RAM
512 GB primary SSD (where footage & cache is located)
3TB 7200rpm cache drive

I've never used a Photoshop psd image in AE CS6, but yesterday I did, thinking I could tweak more easily...it's a flat (non3D) one-layer image with alpha. I dragged it into the project. The layer has some intense rotation expressions if that matters. I can work on it fine, it plays using RAM preview and I can save a portion of it as a RAM Preview Save, which is also fine. But when I render to a video file, the object disappears complete....I just get a black screen.

I created a 3D object (a Doctor Who TARDIS) just for fun and I'm trying to figure out how to animate it spinning in space with the orbit camera and keyframes. I do the orbit and the keyframing works fine, but when I play it back the whole thing zooms in and out madly, almost like it is throbbing in and out. This funny "throbbing" happens in between the keyframes.
The zoom attribute in the camera options is actually locked, the only attributes changing as I move along the timeline are the position attributes, which I am keyframing off.

I am working in Photoshop CS6. I am putting a light effect over a layer and the lighting effect using the alpha channel.Everything is fine in the preview stage, however when I go back to the main part of my document the effect appears for a little while then disappears. I save it before it disappears as a JPEG and as a psd to input into indesign but when saved the lighting effect does not show up on either file.

I am relatively new to After Effects CC and am using it to create a stop motion film with a large amount of photos.Usually, when importing the individual images into my composition panel, a sequence of editable rectangles appears in the composition panel allowing me to edit the frame length of the still photos.
After around 950 imported images, the little rectangles suddenly stopped showing up. But when looking at a preview of the project, it's as if the photos are in there, in the sequence they should be. I'm just unable to edit them like the previous ones with rectangles showing.
The area of issue is where you see the descending sequence of boxes in the comp panel. The red tracking bar is there to show that there are still photos continuing the sequence.

sometimes in a heavy scene - it seems to depend on the topology/object count, more than on the actual poly count, when you start moving the viewport/camera there is a short lag in the first second. I assume that has something to do with the directx caching. If you know what i am talking about - here is the workaround: freeze everything you dont need right now (and set "frozen grey" to off). for some reason the lag is no more.
When you use the "orbit" button this is not happening - i guess the time you need moving the mouse from the button to the circle does the trick.
A personal comment at the end: i use 3d studio since the release 4 for ms-dos - so i saw it evolving in the past 15 years and used it nearly everyday. since max 8-9 things went worse with every new release .
