After effects error ram preview needs 2 or more frames to playback

Hi there,

this has been asked before, but none of the given solutions solved the problem for me.

As soon as my projects get a little bigger, Playback is limited to just a couple of frames, before it jumps back to the first cached frame.

On my current project, most of the time playback doesn’t even start but prompts me with the message:

After Effects error: Cached Preview needs 2 ore more frames to playback (actually the german version of it: After-Effects Fehler: Wiedergabe einer Cache-Vorschau benötigt mindestens 2 Frames.)

When this Error occurs, After Effects only uses about 2.5 — 5 Gig of the installed 16 Gig RAM, although i set it up to use 12.

CPU usage is arround 15%

No other CC applications are running, browsers are closed.

On this specific project, i have a couple of audio layers and 4K Video Footage (XAVC-S / .mp4 from a Sony A7SII)

The «rewinding» Playback after just a few frames also occurs on projects that have no video footage but are done fully within After Effects.

My PC Specs:

Windows 10 Pro 64bit

Intel Core i7-4790 @ 3.60GHz
16 Gig Ram

AMD FirePro W5100 (FireGL V)

After Effects CC 14.0.1.5

Windows and After Effects running on a 232 Gig SSD with currently 36,5 Gig available space.

Some of my footage is on this Drive, most is on a regular HDD (450 Gig/360 available)

What i already tried:

— Raising the allowed RAM from 8 Gig to 12.

— Purching the Disc Cache (Its currently set to 15, but raising it didn’t change the result)

— Cleared Databank and Cache

— Unchecked «Reduce Cache Size when system is low on memory»

— Reduced Viewer resolution to Quater and turned on «Fast Preview»

— And of course i closed, reopened and restarted the PC…multiple times.

Thank you!

How to Fix the ‘Cached Preview’ Error in After Effects

Let’s fix the dreaded ‘Cached Preview’ error in After Effects.

If you’re reading this article then chances are you probably have just recently received the dreaded ‘Cached Preview Needs 2 or More Frames to Playback’ error in After Effects. This error usually leaves me feeling like this. but that doesn’t mean you can’t do something about it. In this article we’re going to talk about how to fix this common error. If you follow all of the steps below there’s a good chance that you’ll fix this error in only a matter of seconds. If you just want to fix the error you can follow the steps below, but first we thought it’d be helpful to talk about why you get this error in the first place.

What’s the ‘Cached Preview’ Problem?

After Effects previews compositions by creating temporary video files that are stored on your machine. These files are known as ‘cached’ preview files and they come in two flavors: Disk Cache and RAM Cache files.

RAM cache files are the preview video files that After Effects plays when you hit the spacebar. The bright green bar at the top of the timeline indicates the portion of your composition that is playing off of your RAM. Most of the time when you get the ‘Cached Preview Needs 2 or More Frames to Playback’ error it is because there is not enough room on your RAM (memory) to load these temporary video files. Because After Effects utilizes RAM to playback preview files it’s advised that you have at least 8GB or RAM if not more in order to ensure that you have enough memory to playback large compositions.

Disk cache files are temporary video files that are typically rendered in the background while you’re working in After Effects. After Effects does not directly preview video from the disk cache. Instead video files from your disk cache are loaded into your RAM cache when you’re ready to preview. You can tell if a frame is rendered in the disk cache by looking for the dark blue bar at the top of the After Effects timeline. Disk cache files can be stored anywhere you want. You can even control how big your disk cache can get under the preferences menu.

How to Fix the ‘Cached Preview’ Error

Here’s a step-by-step guide for fixing the ‘Cached Preview Needs 2 or More Frames to Playback’ error in After Effects.

1. PURGE RAM CACHE (MEMORY)

The first thing you should do is purge your RAM. This will erase any temporary cache files currently stored in your memory. To do this navigate to Edit>Purge>All Memory. This will reset your RAM cache from scratch.

2. EMPTY YOUR DISK CACHE

You can also try emptying your disk cache. The fastest way to do this is to navigate to Edit>Purge>All Memory and Disk Cache. This will (obviously) purge both your RAM and Disk Cache.

3. CHANGE RAM RESERVED FOR OTHER APPLICATIONS

After Effects allows you to set how much RAM is available for other applications. This is especially important if you have multiple applications open at the same time. If you use After Effects a lot I recommend giving After Effects as much RAM as you can. Navigate to After Effects>Preferences>Memory… From the popup menu change the value of ‘RAM reserved for other applications’ to a low number.

4. CLOSE OUT UNNECESSARY APPLICATIONS

If you have a lot of applications open on your machine you may need to close them out so After Effects isn’t competing for memory. I have a nasty habit of leaving Premiere Pro open when I’m working on After Effects projects. Go ahead and close out any unnecessary applications. This includes Spotify and iTunes. Just listen to music on your phone if you can’t stand the silence.

5. CHANGE PREVIEW QUALITY

The fastest way to reduce the size of the file being written to your RAM is to reduce the preview quality on your machine. To change this hit the menu at the bottom of the composition panel. By default it should be set to ‘Auto’. If you have a complicated project that won’t render go ahead and reduce this to half, third, or quarter. There’s also some handy keyboard shortcuts for doing this:

6. INCREASE DISK CACHE SIZE

You also might be running into an issue where your disk cache is simply not large enough to effectively render in the background. To troubleshoot this go to After Effects>Preferences>Media & Disk Cache. Once the popup window appears increase the size of your disk cache. I like to keep mine above 50GB, which should be more than enough for most projects.

7. UNCHECK ‘REDUCE CACHE SIZE WHEN SYSTEM IS LOW ON MEMORY’

Some people have found success by navigating to After Effects>Preferences>Memory… and deselecting the ‘Reduce cache size when system is low on memory’ button.

8. CHANGE DISK CACHE LOCATION

One common problem that people have when it comes to rendering in After Effects is placing their project files and their disk cache on the same drive. This can bog down your machine as After Effects will read and write files simultaneously to the same drive. Instead it is recommended that you separate your disk cache and project files across two separate drives. I typically have my project files on an external SSD and my disk cache on my local storage.

To change your disk cache location navigate to After Effects > Preferences > Media and Disk Cache and select ‘Choose Folder’ under Disk Cache.

9. SAVE AND CLOSE AFTER EFFECTS

While it may seem obvious sometimes this error can be often be solved by simply closing out After Effects and opening it back up. In my experience this will fix the problem for a few preview renders, but the error will likely pop-up again.

10. CLEAN DATABASE & CACHE

If you’ve made it this far and are still seeing that dreaded error it’s not the end of the world, but we will need to start getting creative. Try cleaning the database and cache by navigating to After Effects > Preferences > Media and Disk Cache. Once you’re there, hit ‘Clean Database & Cache’.

11. SET WORK AREA TO THE APPROPRIATE DURATION

Sometimes this annoying error can be fixed by setting your work area to the exact length that it needs to be. You can very quickly change your previewable work area by using the B and N keys to set the start and end of your work area.

12. SET YOUR REGION OF INTEREST

You’ve likely accidentally set your region of interest once or twice when working in After Effects, but this little-used tool can actually be very helpful when you’re trying to preview a small portion of your video frame in After Effects. In short, After Effects will render a smaller portion of the video instead of the entire frame. You can activate the ‘Region of Interest’ tool by navigating to the small region of interest button at the bottom of the composition panel.

13. OPTIMIZE YOUR EFFECTS

Not all After Effects are created equal. Some effects like the Lens Blur effect are simply much more intense on your machine than say a Fast Box Blur effect. Before you give up on your project try changing out any effects that may be unnecessary for your scene.

14. ORGANIZE YOUR PROJECT

Ask yourself if you’ve organized your project in an efficient and practical way. A project with hundreds of pre-comps and unnecessarily large asset files could possibly benefit from some better organization. It may be tempting to want to just hop into a big project and start animating, but this is actually a fast way to get lost in a disorganized project. Spend some time on the front-end to plan out your project and you might not end up with the ‘Cached Preview’ error.

15. RENDER INSTEAD OF PREVIEWING

While this is certainly not what After Effects was designed to do one solution that could work would be to render out your project in the Render Queue instead of previewing the project in After Effects. For example, if you’re working on a huge Element 3D sequence it might make sense to work in the wireframe preview mode until you’re ready to export. In a way this method of animating is very similar to a 3D pipeline, we’ve just been spoiled by After Effects’ quick previews inside of the composition.

16. OPTIMIZE YOUR MACHINE

It’s time to take a look at your computer. We all know that After Effects is an incredibly intense program to operate. If you’ve optimized your project and are still receiving an error it might be time to consider upgrading your hardware. The first place to look would be your RAM (because that’s where RAM cache is stored), but honestly if any part of your system is lacking it can bring the whole animation process to a screeching halt. Go check out Adobe’s recommended system specs to get an idea for the type of machine you should be running. Sure a system upgrade can cost some money, but if you’re working in After Effects every day it is definitely worth it.

So that is every way that we were able to find that could potentially fix the ‘Cached Preview Needs 2 or More Frames to Playback’ error in After Effects. If you want to learn more about After Effects check out the rest of the site here on School of Motion. Hopefully this error hasn’t completely ruined your day, but look on the bright side. a bad day in After Effects is better than a good day at a ‘normal’ job.

‘cached preview needs 2 or more frames to playback’

ive no clue what im suppose to do. please if you suggest something, explain it to me very clearly in case i dont understand. this is urgent client work and i dont wanna be waiting for responses too long.

Max Haller

If it’s only a problem with that one comp try to figure out whats different between that comp and the ones that are working. It sounds like you tried everything that would rule out problems with the cache. I’m confused why the rendered file would be incompatible too.

Try deleting a layer or effects and previewing and if that works then at least you’ve isolated the problem. Try opening the comp in a new project or in a new comp too

Jeff Kay

If you are rasterizing the AI files it might be worthwhile to instead export those as raster rather than using the AI files directly. Also, how much are those files scaled?

If it doesn’t affect the final product, try converting the AI file to a shape layer (shape layers can only hold paths/fills/stroke and no gradients).

There is a possibility that the AI files themselves are not very well optimized and contain far more information than is necessary and directly trimming down superfluous information in the AI files themselves could improve performance. I guess also try turning off individual AI files and see if it will preview with about half of the AI files active, or if there is one particular AI file that is causing the difficulties.

Agne Jurkenaite

thank you both! its fortunate the designs are super simple so everything was convertable to shape layers. i believe the true problem was the puppet tool. strange. was there a particular reason why? is my computer not strong enough to handle puppet tool? curious to know

Jeff Kay

I have noticed a whole lot of rather odd issues with AI files in AE. As a result I end up either moving the vector information out of the AI file (into something that can hold paths like a shape layer), or I end up opening it in Illustrator to export a PNG (sized such that I don’t have to scale it much, if at all); depends on whether I need the image or I need the vector information.

As to what’s causing it, I have no clue. Here are a list of things I’ve seen that have caused issue with AI files in AE.
-Scaling the file up too much
-Scaling the file down too much
-Gradients in the file
-Unoptimized file (any mess of too many superfluous paths, too many points in paths, extra layers that are not visible, incomplete paths, needless nesting of groups)
-AI files with links inside of them
-Fills that overlap
-Precomping anything with AI files
-Multiple artboards
-You are close to a deadline

Try the puppet tool with raster images, shape layers, and video. The puppet tool is more resource intensive than most simple effects, but it hasn’t seemed to be a resource hog the way 3D lighting, particle generators, or any of the other big resource intensive effects.

Agne Jurkenaite

reading that list, i definitely ticked off several. all these ai files were done by someone else and looking at them they could use some organising. thanks a bunch!

Tarun Jatav

I am facing the same issue. I have an AI character and used puppet tool when I choose the continuous vector to option it give the problem otherwise it is working fine for my case. But I want to use a continuous vector if anyone can provide a solution plz help.

How can we improve After Effects?

I’m currently in 2018 cc and I just hit space once and it doesn’t preview anything. Then I save and when i open the after effects the box is my composition doesn’t show anything. This is really annoying because I tried everything, purge the cache and all.

10 комментариев

you have to increase the preview bar size right to play the frames which should be more than 2

In the case of the illustrator file with a puppet tool, change the puppet engine to legacy seems to solve the issue.

@Atanas Atanasov still doesn’t work. I don’t have a big project, just a few layers with parenting and some duik scripts. I just hit space «once» and the error box pops up.
This is a problem that happens to many people for not particular reason and Adobe must fix this. This happens since 5 Version and it’s 2018 they haven’t fix it yet.

@gab Did you tried 1/4 resolution and then wait? Usually heavier projects cause that. If the project you open is not heavy, the problem and the solution may be other.

Followed what Atanas said and it still doesn’t work. Very frustrating.

It’s too easy to solve! Happens to me on almost any template I open. Just wait. If your PC parameters are lower than others you may have lower loading preview speed. What I experienced was that:

The bar, showing the progress of loading frames, was blank. I waited around 15 min or less and it came.

When you have nothing in the preview window, that most often will mean that your preview hasn’t loaded yet. Yeah, you may not want to wait. But no other options except if Adobe fix that.

Могу только предположить. Возможно папка Image.
Поищите эту композицию в других папках.
Или на крайний случай скажите что за проект вы редактируете.

Юрий вы не правы.
При копировании композиции на таймлайн мы получим «зеркало» копируемого.
Т.е. при вставке контента в одну композицию, он автоматом вставится в копию.
Что бы этого не случилось дублировать надо именно в окне проекта, как я показывал ранее.

Если все перечисленное выше не помогло (или просто вам неохота возиться, пробуя все подряд), значит, скорее всего ошибка происходит из-за конкретного проекта. При возникновении ошибки или другой проблемы обратите внимание на таймкод (время) ошибки. Если баг возникает каждый раз в одном и том же месте, то есть вероятность, что он вызывается каким-нибудь конкретным эффектом или анимацией, которую придется изучить и, возможно, изменить. Например, при работе с частицами можно выбрать другой режим работы CPU/GPU в плагине (если поддержка есть), уменьшить количество частиц, для Element 3D упростить геометрию, уменьшить количество полигонов, проверить материалы, текстуры, размер и т.п.
Для уточнения проблемного слоя или эффекта мне несколько раз помогал такой способ. Вы выбираете половину слоев в композиции и удаляете их все. Рендерите видео, ну или как вы там предпочитаете проверять. Тут возможны два варианта:

• Если ошибка пропала, значит, она была в удаленных слоях композиции, отменяем удаление, и теперь удаляем только половину удаленных ранее слоев. И снова запускаем рендер.
• Если ошибка осталась, то продолжаем дальше удалять слои, упрощая проект.

Если ошибку вызывает что-то конкретное, рано или поздно мы найдем виновника таким методом. Я понимаю, что это долгий, муторный и неудобный способ, но если вы знаете лучше, то пишите мне, буду благодарен!
А если ошибка возникает каждый раз в случайных местах композиции, то можно попробовать рендерить не готовое видео, а набор кадров Image Sequence. В After Effects есть несколько пресетов для этой цели под общим названием Multi-Machine Settings/Sequence в очереди рендера Render Queue.

В таком случае каждый кадр будет отдельным изображением на диске, и если рендер оборвется, вы не потеряете уже просчитанный готовый материал. А когда вы продолжите рендер (можно продублировать задание в очереди рендера Render Queue), After Effects пропустит уже существующие на диске кадры и начнет считать со следующего места. За это отвечает отдельная настройка в Render Settings — Skip existing files (allows multi-machine rendering) («Пропустить существующие файлы (позволяет осуществлять рендеринг на нескольких компьютерах)«).

Но, естественно, звук в таком виде не получится вывести из программы After Effects и придется потом дополнительно его считать как WAV файл без видео и объединять с набором отрендеренных кадров композиции. Их, конечно же, надо предварительно импортировать в любую программу для работы с видео — After Effects, Premiere Pro, да любую. Даже мой любимый FFMPEG может это сделать, да все нормальные программы умеют делать такое. Только проверьте частоту кадров, так как куча файлов на диске не имеет такой информации, и это надо задавать руками.
Вообще, это было сделано для рендеринга по сети несколькими компьютерами одновременно, чтобы они не считали одинаковые кадры, назначенные другому After Effects. А самое интересное, что такое можно провернуть и на одной машине для ускорения рендера, ведь одна копия After Effects не задействует ресурсы процессора CPU на полную.

Please for the love of god and all that is glory, help me fix this bullcr*p.

I’ve tried prettymuch everything I’ve found online and AE CC 2014 Keeps popping up with that message, no matter what I do or what video file(s) I use.

If anyone has any fixes, I’m happy to try them out, even if I have tried them before already, I will try them again and again if necessary..

UPDATE: Updating QuickTime fixed the problem for a minute, and I was able to prerender a few frames untill it gave the error again.

UPDATE 2: Upgrading Codecs had the same effect as updating QuickTime did, I was able to render a few frames, albeit extremely slowly, and then AE started throwing the error at me again.

UPDATE 3: Converted the .mp4 file into .mkv and .m4v, neither work.

UPDATE 4: .mkv, mp4, m4v & .avi file types do not work.

UPDATE 5: I’ve installed AE CC 15, 3x CC 14, 2x CS6, CS5. Reinstalled QuickTime 10x. Delete Adobe Prefrence Folder 15x.

UPDATE 6: I’ve traced the problem down to Media Core freezing upon launching AE, and AE not registering QuickTime.
