After Effects: MP RAM Vorschau Problem bei Frame-Interpolationen

Hallo Zusammen,
ich nutze die neuste Version von After Effects CC unter Windows 7.
Wenn Multiprocessing für RAM Vorschau aktiviert ist tritt bei mir folgendes Problem auf:
Wenn ich Frame-Interpolation nutze, dann flackert die RAM - Vorschau zwischen Video und dem AE - Testbild (das normalerweise angezeigt wird, wenn eine Mediendatei fehlt) hin und her.
Keine Probleme habe ich dagegen, wenn ich die RAM - Vorschau ohne MP erstelle oder keine Frameinterpolation genutzt wird.
Ich habe außerdem schon probiert, AE weniger Kerne oder mehr RAM zuzuweisen, was jedoch keine Verbesserung bewirkt hat.
Handelt es sich hierbei um einen bekannten BUG in After Effects CC oder hat das nur etwas mit meinem System zu tun?

Ist wohl eher ein Bug...

After effects cc RAM preview problem

I recently bought a new rig
i7 4790K running at stock
8gb 1866mhz corsair vengeance pro ram 2x4gb
EVGA GTX 770 2gb superclocked
WD Black 1TB 7200rpm
Samsung 840 Pro 128gb
Asus Z97-PRO motherboard
I run AE and open a file and import my clip (59.94fps) and add twixtor and then hit ram preview to see if all is good and it either takes a little bit longer than it should
or it would say "Rendering frame switching to foreground" When this happens all seems ok but after the preview I can not scroll through the timeline without lag and pixelation again like as if I havnt hit the ram preview. So it would have the green bar above the clips showing for the ram preview but once the preview is over I can scroll through the timeline for a second then the green bar goes away. I know that the pixelation is due to adaptive resolution
but I have tried changing that to "fast draft" and the pixelation stops but still struggle to view in timeline. I have the preview resolution set to third or quarter.
I thought that getting higher clocked ram would solve the problem atleast a little more. But not to much. So my main question is what am I doing wrong? Or how can I correctly setup AE or my computer to handle this?
The main clip is actually 200fps but I go to File>Interperate footage>Main>Conform to framerate
Changing it from 200fps to 59.94.
My main frustration is I see videos of the kinds of clips I'm editing posted by kids that edited them and I think theres no way they have a pc as expensive as mine that would allow them to edit these clips. So Its gotta be something I'm doing wrong.
Thank you to anyone that helps so much!

Well, for starters, turn off MP rendering. That warning during RAM previews is a clear indication that you are using it and well, with just 8GB RAM it doesn't exactly make sense. The rest is too vague since you haven't provided any proper details about your source file, but suffice it to say that temporal mangling of any kind can have weird effects, even more so if your source files are compressed. Therefore the pertinent thing to do first would be to convert your file to an uncompressed intermediate format, including conforming it to your target framerate. In addition you may simply consider not using any fast previews or the disk cache at all. It is known to be flaky with temporal plug-ins. set your comp to Final quality to enforce software mode rendering.

"After Effects error: RAM Preview needs 2 or more frames for playback"

i7-980x, Win 7 64, 16 gb RAM
I STILL get the "After Effects error: RAM Preview needs 2 or more frames for playback" and max allowed memory of 0.4, despite max usable memory listed as 15.99. Sometimes if I run Premiere Pro, PS, AI, 3-4 QT movies and 5 or six other programs simultaneously, after effects will recognize Premiere Pro and allopw me 5-6 gigs active memory, but this can take an hour or two and is hit and miss.
VERY FRUSTRATED here.
This happens with and without the firewall turned on.
Please help

I get this error message when I accidentaly move my CTI (Current Time Indicator) to the end of the composition. If besides also the option "From current time" in the preview panel is checked, After Effects will see that I just marked less than 2 frames namely 1 (from the end frame of my comp to this end frame).
Check therefore where your CTI is positioned!
Also you could have the same problem, if this option "From current time" is not checked, but you have your work areas in- and out-points closer than 2 frames together.
So condensed: Check your CTI and your work area and set the CTI on a previous frame or let your work area start earlier.

After Effects Error: RAM preview needs 2 or more frames to playback

I keep getting this error message on a Windows 7 64bit system with 12GB of RAM. I have tried rebooting and re-installing the application and After Effects still gives me this error message when I press '0' to perform a RAM preview
Any suggestions would be appreciated.
Thanks

I would suspect that is the problem.... From what I gather, it uses H.264 compression inside MOVs, but it may use an unusual, non-standard profile and thus throw off AE. Can you check these settings in the extended info in the Quicktime Player? would help to know some more details. If you have Quicktime Pro, it may be enough to re-export the clip from there. Using identical settings, this should go pretty fast and not cause any changes in quality, but doing so may fix little annoyances commonlyy associated with such formats like open gaps or invalid timecode markers. If that doesn't help, then I guess it's time to run it through SUPER©, ffmpeg etc. to get workable converted files...

Adobe After Effects CS6 Ram Preview Crash Problem

Hey, Recently my AE cs6 has been crashing when I started to RAM preview and the message that shows up is. "After Effects error: Crash In Progress. last logged message was: <1948><ai.blit.pipe><2> HardwareBlitpipe Disenaged."
Specs:
AMB 8150

After Effects will RAM Preview not in real time

Hi, we have 3 adobe After Effects CC up to date here, we are working on a 60fps project in HD 1080. Nothing crazy.
We have 20 Gigas of ram. Mac OS 10.8.5 octo core 2011. ATI Radeon HD 5870 1024 Mo. SSD disque crucial m500 256 gigas.
We have a lot of problem with Ram Preview. (on every project)
Everything works fine until, we don't know why, the ram preview is getting not realtime, like 30fps or under.
Sometimes purge memory do the trick but not always.
We need to reboot and it works again, but few minutes.
We made a test on CS5 and it works well realtime, but same problem on CS6.
I tried to delete all the preferences to check but no difference.
We are working with nfs network account but i always redirect disk cache to local disk (set to 20 gigas) and also media conformed cache (database and cache)
We are getting mad, it's really hard to work that way, rebooting each time.
Maybe an issue with Global performance cache introduced in CS6 ?
It's not a footage/project issue because the entire project (a blend of tiff, png, prores422) can be played 120 frames/sec without any problem on after CS5, after CS6 (when it works), CC (when it works).
The problem is when working on project, changing layers, adding effects, After CC starts not be slow and not realtime using Ram Preview.
Also, when we are previewing, a lot of ram is not used, it only uses like 20% of the ram.
We hope for a nice patch very soon ....

60 fps is a very high frame rate not usually supported. If your footage is shot at 60i then it is probably 29.97 fps when converted to progressive video. If the footage is actually 60 fps then you will be better off, and by better off I mean more folks and streaming services will be able to view your video at the proper speed.
So my recommendation is to first determine your audience and then set up your comp appropriately. In all my years in the business I have only delivered one high frame rate project and that was 48 fps.
The other thing I would recommend is to optimize your system for AE. That does not necessarily mean throw all your available ram and processors at the app. There are some good recommendations here: Optimizing After Effects Performance

After Effects CS5 DNxHD rendering problems

Hello folks, I posted this last month, but still haven't worked it out. My problem is that everytime I try to render a quicktime from After Effects CS5 using Avid's DNxHD codec, I get this error, about 60 - 100 frames in: "Rendering error while writing to file (path name here). An output module failed. The file may be damaged or corrupted. (-1610153464) I've tried rendering to different drives, rendering with and w/out multiprocessing, with and w/out Open GL rendering, different comps / projects, and different flavors of the DNxHD codec (8 bit, 10bit, 145, 220, etc). Here's my basic system specs:
Win 7 Pro 64bit
Dual 6 core Westmere Processors
48GB Ram
Quadro FX 3800 1.5GB (driving 2 x 24" HP monitors)
GeForce GT 240 (driving a Cintiq tablet)
I have another system, same operation system, but with dual quad core Nehalem's and 16GB Ram and a Quadro FX 3400 and it renders to DNxHD just fine. I'm certain I have the latest codecs from Avid, and I've tried both the LE and PE versions. Any thoughts?
Nate

It's a bug in the CoDec itself, if I'm not mistaken. I've seen this being discussed somewhere, but can't remember the full details. I believe the issue oils down to the Avid stuff using an older version of some compiler library and not dealing correctly with some SSE stuff on some processors. You may try to toy around with the BIOS settings to suppress SSE4 and 4.1 and see if it helps. Also consider installing the .NET runtimes. They still have those magical healing poweers, as the install resolves any version conflicts that may exist with outdated system DLLs bundled with some programs. That may also help. In the long run, though, I think Avid will just have to update DNx to properly work on 64bit and those new processors...

After Effects Lossless AVI Export Problems

Hi,
I have a very strange problem that only occurs sometimes. It is kind of hard to explain, so bare with me.
I'll just explain my process first:
I import and edit all my video files in premiere pro CS5.5. Then I import my Premiere Pro Project into After Effects CS5.5 for Color Grading. While I scrub through my footage everything looks fine.
I then Add my Comp to the Render queue, and select Best Settings, and Lossless AVI with Audio Output.
After the footage renders, I watch it and every now and then a frame will be inserted from at least 7 frames up into the current time. This makes the footage look choppy/jumpy. Example: The character is walking and for one frame he will jump a couple inches forward, and the next frame he will be back again.
This might happen a couple times in a row or every other shot. I thought maybe my computer was just playing it slow in Windows Media Player - but I imported the Lossless AVI file into Premiere Pro to play it in that, and it still has the same problem.
I don't know what the problem is. I would just like my AE Comp to output smoothly without adding those extra frames on my footage.
Here's an example image:
If any of you could please help me, that would be great! Thanks!

Okay, I just made a bunch of tests.
1) I converted an .MTS file to an .AVI with the Lagarith codec. Then I imported that into AE. When I RAM Previewed it, I did not get the jump from frame to frame thing.
2) I also imported the same video file, only an .MTS version and RAM Previewed that. Again, I did not have the problem I have been having.
3) I made a new Premiere Pro Sequence and imported the same .MTS file I had been using. Then I went to AE and imported that Premiere Pro project (trying to go through the steps that got me to the problem in the first place), and tried RAM previewing that. Again, I did not have the problem I had been getting.
So I obviously cannot re-create my issue. But the issue is still there in my other AE project. If I open up my AE Project that I had the problem with in the first place, I still get the jumpy frame issue when I preview it!
I even tried creating a new AE project (willing to re-color grade all my footage), hoping that the problem would not be there. But when I create the new AE project and import my Premiere Pro project, the issue is still there.
Is there something wrong with my Premiere pro project? When I play my premiere pro project without it going to AE it works fine, no issue. But when I import it into AE the issue is there!
It has to be the Premiere Pro Project or the sequences in that project. Since, like I said above in test number 3: " I made a new Premiere Pro Sequence. Then I went to AE and imported that Premiere Pro sequence, RAM previewed that. And I did not have the problem."
What is going on? Will re-editing my entire project in a whole new Premiere Pro project fix my issue? What if it doesn't, and this happens again? How do I fix this?
I really appreciate your help. I'm glad there is a place to go when I have a problem with Adobe Programs. I would never be able to figure this out by myself. Thanks!

Black magic and Adobe After effect cs6 Ram Preview not real time

Hello,
I'm on a MAC PRO with the OS 10.6.8 and 8Go Ram, the problem is when i turn on my preview video on the Blackmagic the video monitor is not in real time and the after effect is so slow. When i put it off (computer monitor only) it's ok but i havn't my video monitor of course....and i need it. Is there some tricks for having my black magic (1080 i 50) ON and a RAM Preview in real time ??? ! My drivers Black magic is the 9.5.3 it's the highest driver for MAC OS 10.6.8 + ADOBE CS6+ FCP7. Thanks for the read. ( i tried update adobe, change qt library, change aspect ratio, pixel, preview ram settings, change drivers black magic and other but nothing work )

What is the color bit depth of your project? (8, 16 or 32?) Have you changed that recently, or have you changed the frame rate or frame size of your comp?
Performance with video preview to an external monitor is almost always related to the pure bandwidth requirements of the frames you're sending to it. If the frames require more memory, it may be slower. Frame size, frame rate, and color bit depth all affect the memory requirements of the frames.
If none of those parameters has changed, troubleshoot the general performance of your machine. If there are other processes (look in Activity Monitor) that are using significant processor and/or memory resources, they may be causing a bottleneck for the frames getting out.

After Effects CS5 Ram, Codecs and Graphic card

hi im using AF CS5 with all latest updates. I have few questions
i have problem with codecs included in CS5. could please someone tell me why when i try to "render que" and i tried every possible codec included in AF cs5 the output is rubbish like hell. i been reading googling etc some on Adobe forums, some people say use 32bit instead 8bit, other say use this codec instead that one another say maybe maybe hmmm maybe .../.. let me think ahhh this codec isnt supported in AF cs5 yet it will be in next 2025 release.
could please someone tell me what codec should i use to make output look like standard video instead crappy sh**t?
ram preview work great no problems when i save on my desktop ram preview, it use auto AVI WRAW (1gb/min) and the video look great im satisfied.
when i checked add to render que codecs under avi, wraw isnt included so i cant use it but why the hell ram preview use this codec?
when i use quick time mpeg avi etc codecs included in cs5 the output look like i dont even know how to describe it look very bad. i tried also encode the shi**y output trough media encoder tried h264 etc tried to use other third party software to correct AF bad output and nothing helped and im tired.!!!!!
how can Adobe sale something crapp that doesnt work ?!!!
where is WRAW ?
what codec should i use to make my 2 min clip look good ?
another thing i got with AF thing called media encoder could please someone tell me why the hell i cant encode AVI movie in it ??? and then make out of it FLV or MPEG etc ?
the result after making out of avi flv or mpeag etc is that the sound disappear probably everyone in Adobe know it. could you please sort it out ?!!!!
why when i use free encoding software such as mediacoder etc no problem with AVI decoding encoding etc?
Another Question i have 4x ATI HD4850 installed so i would like to use it right ?? why? cuz everyone on earth know that normally graphic cards are designed for graphics.. not when you use Adobe products. Adobe preffer to make people buy 280gb of ram and 20 x Q9000 quad core.
why the f***K open GL After Effects doesnt work ???? just dont ask me what opengl ver do i have !!!! when i use open gl the rendering is slower with Gpu than than using the CPU whys that? why it isnt in MAYA ??? etc
people buy product people expect it to work right ?not install it then install all plugins you need, then try try and try to make AF work. AF remaind me Linux still use it sometimes, when you install ubuntu you need a bit of time to make your graphic card work sound etc many of your devices wont never work cuz they arent supported no drivers or buggy drivers. the thing about linux is that it is free.
Adobe cost money so people expect it to work i dont have time to wait or try to make it work for the next 5 years !!!!!

If you're looking for help this is a great place to be. Just maybe dial back the "adobe sucks" rhetoric a bit. The folks here are extremely helpful but I think they're all volunteering their time so try to keep that in mind. Nothing wrong with complaining and/or suggesting improvements. Just try to respect the process and be patient. If you ask one or two specific questions (i know you did re: sound in .avi files) you'll get help faster.
wish I knew why OpenGL for rendering was still so bad. I was told long time ago "just don't use it for rendering" and I've followed that advice ever since. Maybe someday it'll be useful. Meanwhile it works great for everything else inside AE so I don't condemn the whole idea of OpenGL in Adobe products. Every CS release supports it more and more...they'll get there. For now just don't use it for rendering and you'll be fine.
At least you're using CS5 and can take advantage of all your RAM. just think, a few short years ago...
Sorry I can't help you with your missing audio in .avi. I generally render to QT or an img sequence and then layer my audio on top of that.
If you find an answer post back - I'm sure it will help someone else.
Good luck!

Adobe After Effects CS4 trial installation problem, Please Help!

Ok, I downloaded the trail version of Adobe After Effects CS4 onto my PC (Windows XP). When I try to run the setup (by double-clicking it), a window pops up saying 'Adobe setup has encountered a problem and needs to close.' Does anyone know why this is, and how I might be able to fix it? I already tried re-downloading it, and I checked the system requirements. I WOULD REALLY APPRECIATE ANY HELP YOU CAN GIVE ME BECAUSE I REALLY WANT TO USE THIS! If it will help here are my PC's specs:
Operating System - Windows XP with service pack 3
RAM - 2.0GB
Graphics Card - ATI Radeon HD 4830
Processor - Intel Core 2 Dual 2.2GHz
Monitor Resolution - 1280x1024
Thanks

Verify the following:
a) you run as administrator
b) your virus scanner and firewall don't interfere
c) you have enough temporary disk space
d) no other tools are interfering
For b), simply turn those tools off during install. For c), check your user temp directory (C:\Documents and Settings\You\Local Settings\Temp). Clean it out either manually or using tools like CCleaner. Also defragment your drive. For d), you may need to uninstall otehr Adobe software. also monitor your task manager for processes and services that may have a negative impact. A dump of those can easily be generated using HijackThis!, so you can post the list here for verification, if needed. also provide any otehr info that could be important, like e.g. special drivers or user settings.

After Effects--Composition not using entire image frame??

Hello,
I'm very new to After Effects so I'm sorry if this is a very simple question. I've Googled it and I think maybe I'm using incorrect terminology because I haven't found anything that describes what is happening. So, I've taken a screen shot to hopefully help illustrate my issue.
I'm using After Effects CC - 2014.1 Release on a Late 2013 Mac Pro. Trying to piece together an animation render from Autodesk Maya.
Right now I'm using a test render so that I can figure out the import settings for when the final one is finished rendering. In this test there are 94 images, each intended to be one "frame" in a 24 frames per second animation. I think I have altered these settings correctly as it seems to be about the correct length (94 "frames" / 24 fps = 3.9167 or 3:55 seconds)
The problem I'm running into is that After Effects is only showing a small viewport of the actual images. I've outlined in the bright green dashed line the approximate actual image size and where in the image it is showing in After Effects. All of the images are the same size and same resolution, and they are all being shown only in this small window.
How can I change the settings to have the final animation show the entirety of the frame? Obviously it's showing such a small area that it won't work for me-- I really need all of that missing information shown.
Thanks for any help anyone can offer.

What size movie does Maya expect? If it's conventional HD, 1920x1080, you must scale your images to fit the comp size. If you need a comp that is 4k you must change the properties of the comp. they are both easy to do but require a bit experience with the AE interface. Start at the beginning of the basic tutorials that we refer to around here.
and welcome to the family. AE is hard. Really hard.

After Effects CS6 RAM usage

Hey there,
i have 32 Gb of RAM in my Pc but After Effects only uses 15% when it renders. How can i set it to use up to like 90%?

You also have to realize that After Effects only renders one frame at a time and a HD frame, when compared to 32GB of RAM isn't very big. Memory usage depends entirely on what's going on in your composition and what codec you are using. I'm not saying that 15% is always the best, but it could be for certain projects while a much higher usage may be shown for others. I have found the recommendations that Todd supplied through his link work quite well for just about every situation I've ever run into. It's highly unlikely that you can achieve 90% system resource usage in any more than a very small percentage of your projects.
