RAM Preview – Not in real-time

Hello.

I'm having a hard time dealing with this new Preview in AE. A lot of times it is not giving me a real-time playback.

It is nice to have the preview continuously playing while making some changes on the comp, but sometimes I would like to have a real-time preview, like the old RAM preview.

Is it possible to generate a real-time RAM preview? I don't mind waiting for AE to render before playing back the animation.

I have tried the Numpad 0 and also spacebar. I've tried to purge all, restart machine, etc...

Thanks in advance.

Best,

Possibly. Your scene description should DEFINITELY have no problem playing back in real time, so something is amiss and that would be the first thing I'd troubleshoot if I were in your position.

Changing the monitor to 60Hz solved the problem here =]

Got the same issue here on a windows machine, since i moved to a 4k Screen. It's a shame paying for those buggy Adobe software, yet nothing really improves over there years.

my setup:

Win10 (latest)

AFX '18 (latest)

Intel 2600k

32gb Ram

nvidia 980TI (hdmi 2.0 4k 60hz)

LG 32UD89-W (4k 60hz)

any ideas? the ridiculous stacking fix helped improving the framerate (yet this a terrible workaround). If i close the timeline, it says it's playing with full framerate (up to 100) on a full preview 3k sequence. but comparing it to a rendered clip in external video player, it's far away from being real time.

so?

Same issue here.

My workstation:

Win 10

AE CC 2018 (15.0.0 build 180)

Intel i7 5960x

64 Go

Nvidia 1080 ti

BL 2711U Benq 4k (60 Hz)

On the same machine, with the same project, AE CC 2014 ram preview give me a rock solid fps playback.

Since CC 2015 the ram preview is wrong with unconsistant framerate playback.

Perhaps you should stop setting these forums to "ANSWERED" when they most certainly freaking are not.

Well, to be fair, changing monitor refresh rate to 60Hz solved it for papanapa , so it's probably the right thing to do for this post. But clearly there are people coming to this post trying to find the answer, only to be let down. #metoo This post doesn't solve all these similar RAM preview issues. RAM previews have been rock solid in the past, and at the moment they are not!

Hello, this is the end of 2017 and I have all updates on Ae CC 2017 MacOS 10.12.6

and I still have this issue on 59,94 fps 1080p composition. The cached area doesn't playback properly and this is very annoying! because it's not obvious at first look and happens from time to time. You just can't get expected result (no matter preview resolution down factor) and the same time you can't understand is this animation timing or playback that is not synchronized. I've tried all the tricks in the thread. Bigger work-areas works slower. I can't believe that this is not a joke to get in a situation when you simply can't finalize the urgent project because of this little annoying bug.

What version number of your OS are you running?

What exact version number of AE have you updated to?

MacOS 10.12.3

After Effects 14.1.0.57

Just as an example, I've just created a simple FullHD 8 layers shape animation on position and it does not give me real-time preview.

After the 3rd loop on the preview it started to run on 29.97fps. But if I stop the preview and press 0 again, without any changes, it won't play real-time preview on the first playback.

My monitor (Samsung 4k) is running on 30Hz, even though the Mac Pro and the monitor both support 60Hz. Could that be an issue?

Mac Pro (Late 2013)

3.5 GHz 6-Core Intel Xeon E5

64 GB 1866 MHz DDR3 ECC

Monitor Samsung 28" 4k - U28D590

Plugged with the HDMI cable provided with the monitor, directly into the HDMI port on the MacPro.

Preview is — no one wants to edit footage in real time. BRING BACK RAM PREVIEW! I have the same problem as thousands of after effects users audio glitching during "Preview" then when it plays the audio it is actually out of sync, preview is never at frame rate, highly frustrating if you use any sort of audio with visual effects, or actually want to preview your work without having to pre render. I am running a mac pro 2015, and this software is just a load of B. I have been using after effects for over 5 years and didn't install the 2015 when they switched to "preview" as to me it seems ridiculous. After effects cc ran better on my 2012 mac book pro than this does on my 2015 mac pro! The "RAM Preview" renders the frames first so then you are assured a smooth playback whatever ram you have installed, now there is no option for ram preview so the use of this program is pointless. Does anyone know how to re-download CC2014 as now in my adobe account I can only access cc2015 which has the same render process as this. Adobe sort it out.

I have paid more for adobe CC than I would if i bought the adobe package back when it was CS6, and now you screw over hardworking people who use your software daily so that you can try and make it cooler! Do everyone favour and test this on multiple machines with multiple different graphics cards before launching the update!!!! Thinking that everyone who uses after effects has a top spec desktop. No one I know who uses this software is happy with cc2015 or now cc2017 "preview" function, yet again you have forgotten about the general user. Please Adobe do some customer research before you bring out a product, ask consumers before you alienate yourself from the market

Everybody who is having this issue, please install the latest update that came out last night: After Effects CC (November 2017) Bug-Fix Update Is Now Available

This update is 14.0.1 and should be a bug fix for this and several other disturbing issues - especially for Mac users. It does not fix all the bugs that are new with the CC 2017 release (Known issues in After Effects CC 2017), but it does fix some issues that have been plaguing After Effects since the first parts of the new architecture showed up in the CC 2015 release.

If you can't see the update yet, you may need to wait a while until you see it as it can take up to 24 hours to populate an update across all the data centers. You may need to log out, relaunch the Creative Cloud app, and log in again.

HUZZAH!

Change the timeline to a Stacked Panel. It should playback in realtime now.

That is so wierd! It did work for me though but how can that be an issue if its stacked or not?

Anyway thanks a lot!

Here's a simplified answer: Mac 10.11 changed how redraw rectangles are calculated when they intersect the region at the bottom of the application window between the rounded corners, which forced After Effects to invalidate how it was re-drawing the timeline and then draw a much bigger region than expected, which slowed down the refresh rate during previews. So, doing odd things with the UI fixes it in some cases (like docking a panel underneath.)

Hopefully a proper fix from Adobe comes so workarounds like this aren't needed.

I have a simple animation which shouldn't be any problems at all to preview but even if I cache the preview, lover my timeline, add a panel beneath it it still previews in 9-15fps with a quarter resolution. This is insane! I need to render out my animation to see it in real time! Unacceptable! My impression is that it's better to install AE 2014 and work in that. The AE CC has had this problem all along!

for now best you can do is shrink the timeline as Szalam said:

Make your timeline smaller. I'm assuming you're working on a 4K or 5K screen. Shrink your timeline panel vertically so it takes up a lot less screen space and try again.
If that doesn't help, try pressing ` to make your comp window fill the screen and try it.
If that doesn't help, try putting another panel (such as the libraries panel) underneath the timeline.

The last one work for me (putting another panel underneath)

Shrinking timeline seems to improve it. But I hope someone fixes this. I'm on a 5k iMac - I shouldn't be having this problem!

Hello, so now its for me also time to get into the discussion because I have the exact same issues with the RAM Preview.

What I tried and what helps to get around this:

- making the timelinewindow smaller, so its just some layers high

- moving the rendered workarea out of the timeline view

If I see the timeline in "normal" size and the rendered work area, it makes also a lot of these vertical lines which look like coming from the current time indicator.

My system is a Z800 Win10 PC with latest AE 13.8.1.38 running. AND I am working with a two 4K Monitor Setup, while Windows scales 125%.

Another "strange" behavior while RAM Preview is, that during the glitchy playback, the Disk Cache is creating a lot of workload on my Media Stripeset, which I would not really expect because it should play out of the RAM? Shouldnt it?

Maybe I also should file in a bug report...

The green bar used to mean a rock-solid assurance that this cached content will play back right now. It now isn't worth the pixels it's displayed in.
