After Effects CC 2017 RAM preview problem

Hey,

i use After Effects two years. Now I had buy new hardware.

System:

i7 6700k

GTX 1070

16 RAM

Win 10 Pro

I thought it works good, but i can't use the ram preview correctly.

If I would play a clip (30s long) without a effect, so the clip rendered to 1 second an played in a loop.

The same clip with a effect for example twitch, it rendered the same time of 1 second and played also in a loop.

AE can use 14GB of RAM and there is maybe 1 or 2 GB in use.

I swichted the view render from CPU to GPU and reversed. I see no different.

Where is the problem (?), my cache had I clean up. By the way premiere work very goog and without problems.

Thank you!

MESMO ERRO! Ta dando Loop

Fiz todos os testes que postaram aqui. É um problema muito estranho...
E fiz meus próprios testes: Não é a potencia da maquina.. Minha maquina é um Notebook Win10 / 16G RAM / SSD / 1T HD / GTX 1050ti 4G

CC Adobe After Effects 2018. Numa composição de 60fps e duração de 20segundos eu coloquei 1stroke 2texto - Funciona tranquilo (consigo visualizar toda timelime)

Coloco um simples efeito de texto do presets do After Effects. Consigo visualizar EXATOS 185FRAMES (6segundos) e gera um loop.

Abaixei pela metada a quantidade de RAM que o programa executa... 8G. Visualizo Exatos 620Frames e volta a dar loop

EXACTLY 3G de RAM dedicated to AE - (1 Stroke, 2Texts, one of tem with NO EFFECT, the other with a "Fade up words" (Effects and Presets - Animation Preset* - Text - Animated in - Fade up words) only preciews, precisely 1058frames in a composition of 60fps with 20sec a full composition.

thats how the preview works according to the RAMs

RAM
3G - Low - 1058 frames (17sec)
8G - Half - 620 frames (10sec)
14,9G - full 65 frames (1sec)

Open After Effects creat
1 stroke animated with Trim Paths
1 Text with no effect
1 Text with preset animation - Fade up words

Revert to Adobe AE CC 15.0.0

the AE 15.0.1 has a bug

After 4 months i got some feedback from adobe support. Obviously their suggestions didn't work.

What worked for me was switching from my great MSI 980TI Gaming Edition to my ooooold ATI Radeon 7850. Et voila... 4k in 60fps Ram Preview is no issue no more. Even the timeline glitches are gone. Seems to be a nvidia issue here, even with the latest nvidia drivers.

Thanks a lot for the feedback. I don't own a Radeon right now but I'll manage to get one and I'll let you know.

Adobe should investigate in this way and tell us.

After six months (!!!) Adobe today closed my 4K major bug ticket with this solution:
Just use FullHD instead. Ticket closed.

No comment.

Ok I may be repeating some posts but this is what i encountered and my fix so far.

My specs: Intel Core i7-7700HQ CPU @ 2.8HGz with 16gb of RAM

I am editing with a very large 4k video files, (4096 x 2160, 60fps .MOV file)

Everyone's case is different but here are some tricks and tips to try fix:

Firstly your preview settings:

1. Make sure you have cache before playback set

2. match your frame rate with the frame rate of your composition settings

3. I have my resolution set to auto, setting this to quarter will allow a faster preview and allow you to preview more as it requires less memory.

Dedicate more RAM for After Effects: Edit > preferences > Memory

Drag the slider to dedicate more RAM. The more RAM, the more cache memory is designated which will allow a "larger green line", making you able to RAM preview more.

Third, use proxies!

No matter how powerful your computer is, sometimes you need proxies when dealing with large amounts of 4k, 6k, 8k files.

For anyone who doesn't know what these are. After effects can render a lower quality of the footage you are using.

You can then edit with this lower quality footage much much faster and when you are finished you simply click a small tick box

and After Effects will change it back to your original footage for you to render.

AND FINALLY!

For advanced users that have done all the above and are tearing their hair out I have found a solution that worked for me.

I use an external monitor connected to my laptop via HDMI. The external monitor was the problem.

I think it was either trying to upscale the output from my laptop causing after effects to play back my RAM preview in slow motion/dropping frames/ skipping etc.

I simply resulted back to using my laptop, but down-scaling the resolution of my monitor also worked. This may also be a result of using HDMI, in that the preview isn't transferring quick enough to the monitor.

As my cache loaded fine and loaded my work area, but on playing back it dropped frames and distorted the audio terribly, like slow motion.

I hope this helped.

Well Fmulvey thank you for your advices witch are a list of good practices but it is not really relevant here since we (by "we" I mean at least myself and Efekt, because it seems that people are talking about different issues in this thread) we are talking about a bug in AE. This bug was introduced in AE since the CC 2015 release. It is related to the UI and the timeline panel and has never been seriously handle by Adobe. In my case the same project, on the same machine, the RAM preview runs perflectly on CC 2014 whereas on CC 2015 to the last version of AE it stutters and lost real time playback.

So it is not a question of settings or proxies or whatever else it is a plain and simple (3 years old !) bug.

If you've ever had glitchy frames in your composition or

if the Composition window is stuck displaying one frame despite moving the playhead around,

sometimes these issues are caused by problems with the cache. Purging the RAM previews often clears these problems up, and if it doesn't, you can try purging the Disk Cache as well.

check this article: The Definitive Guide to RAM Previews and Disk Caches in After Effects (i.e. Those Blue and Green Lines) — Video Review &…

Hope it helps you.

Thanks for the response Kevin,

As far as I can tell, this isn't an issue with my monitors. I've been working off of this Apple Thunderbolt Display on this new Windows machine for a few months now and had no display related issues. I believe this is an issue that happens occasionally in AE 2017, where the project gets corrupted, or something along those lines. So, far I've been able to workaround this issue by importing the problematic project into a new project. In the case of the project I was referring to in the previous post, I had to rebuild the whole thing from scratch, which was annoying, but didn't take that long. I will report back if I notice an increase in the occurrence of this particular issue. I'm still not sure what causes it, but it seems to only happen occasionally.

SAME PREVIEW ISSUE AS DESCRIBED BELOW. Their computers are even much better than my 8GB RAM machine, yet we're experiencing the same issue??? If it's not ram, what's really going on Adobe? Just to skip frivolous questions, my comp is 2013 yet fits every requirement to run AE listed under "System Requirements".

"This happens, in both After Effects 2017 and earlier versions where the space bar preview, or any other form of normal RAM preview, i.e. button click, or using the 0 key on the numpad, no longer works. The green bar fills up as it caches the shot into RAM, but then I get just one or two frames of real time playback, maybe more if I'm lucky, but never the entire shot and then it just stops dead. I can scrub just fine, but I can't preview an entire shot. I've been using AE for almost 11 years now and never had an issue like this."

Is there any ETA for a RAM preview fix? Going by the thousands of people looking at this thread, it is a pretty clear problem.

I have the same problem and all I have in my pre-comp is one simple 3d logo rotating and than the trim stroke effect... and the comp "above" i have some camera movements - not too complicated too - and I can't preview it whole, it gets stuck after 1 sec! Please, help! I can upload my ae file if it would help find the solution!

You have the minimum ram required for AE. If your comp is HD and and the resolution is set to full then you won't get a very long ram preview. This is normal. If you are new to AE then you have not studied the app to learn how it works. If this is something new then something else is going on.

Changing the preview to the lowest possible resolution isn't changing a thing, and I can preview it in a composition that has in it the pre-comp, but I cannot preview it in the pre-comp itself. I've done much more complicated things with such RAM on AE CS6 (3d objects built from vector images with heavy camera movement), and it worked. I had to wait a while to generate the preview - that's ok. But here - no loading, no nothing.

I just did AE 2017 latest update and I again have issues with playback (it slows down everything and audio becames slow). Horrible. Will adobe at least try to fix this bloody issue. I don't want workarounds, I want it work properly already, I've been waiting for Adobe to fix this for almost 3 years now.

So angry...

Adobe has fixed several causes of this issue.

Unfortunately, it seems they haven't fixed what's causing the issue for you.

But, we forum volunteers can try to help! (It might be a simple fix.)

What OS are you using and what monitor(s)?

Does docking another panel (like the Progress panel) underneath your timeline help?

What are you running previews of? (Footage, 2d layers, 3d layers, etc.) What are the specs of any footage or assets you're using?

Do you have issues after a preview has been cached (green line over the whole work area) or are you talking about it running slowly while it's caching a preview?

Hi Szalam, thank you very much for your help.

- I'm using MacOS Sierra 10.12.5 - MacPro 2012 - Dual Xeons - 64GB Ram - SSD

- Apple LED Cinema Display 27"

- Yes it does

- Running extremely simple 3D rendered footage!! (1920x1080) with few solids here and there, nothing heavy

- That is the issue. Issues is that is jagged after it's been cached with numpad 0. I wouldn't have complained about anything else, what's making me crazy is that it's jagged after being cached.

I'm using After Effects since CS3 version, this never happened until 2014 or 2015 I think.

Has anyone found a solution for this? I'm on the current release 14.2.1.34. I've tried minimizing the timeline, moving the timeline below the comp window, adding another panel to the timeline window group. I've also tried updating my video driver. Sometimes it works, sometimes it doesn't. This is severely impacting my ability to work.

You've docked another panel (like the Progress panel) underneath the timeline?

Wait, you wouldn't happen to be using a Dell 4K monitor, would you?

I think the latest update fixed the issue with the 4k monitors.
