Interlace RAM-Preview in After Effects?

Hi :-)
I'm working with 1080i50 Video-Footage (Interlace)...
And I'm searching for a possibility to get a "real" Interlace-Preview in After Effects with an external video card (for example Intensity Pro)...
If I play out the RAM-Preview I only get a progressiv-Preview and the Interlace-Fields are visible...
What can I do to get a correct Interlace-Preview from After Effects?
(I use Adobe After Effects CC 2014, iMac, Intensity Pro)
And by the way, Interlace is still STANDARD, I can't use 1080p50 because this is not a compatible Standard for a Video BluRay...
Who can help me?

I have done AFX work with my 25i material, you just have to make sure the field order box is checked when exporting.

Ram Preview - Stopping after 40 frames

Hi All,
I've recently moved to After effects CC on my home computer, and for some reason whenever I try and RAM preview it stops after 40 frames or so...
The animation is REALLY basic (full screen shape layers turning on and off to the music) and an mp3 file playing in the background.
My computer spec is:
21.5-inch iMac Mid 2011
OSX 10.8.5
2.8 Ghz Intel Core i7
16 GB 1333 MHz DDR3
AMD Radeon HD 6770M 512 MB
I have the following multiprocessing prefs:
I would greatly appreciate any help on the matter... the project seems far too basic for it to be having genuine issues with playback...
Dan

Hi Rick,
Thanks for the reply.
I've changed the .mp3 file to a .wav file and that seemed to fix everything, for the time being...
It previewed for 10 seconds fine, but after about 15mins of working on this the RAM preview area has started to shrink again and it's only previewing just over half (5 seconds).
I changed my memory and allocated 4GB to other apps, also turning off rendering multiple frames... (by the way for some reason I can't get my 'actual cpu's that will be used' to change from 0? This seemed odd). Still no change.
I've attached a screenshot of my comp details below, along with a shot of my screen when RAM previewing... (you can see the green bar does not go all the way). I'm not working with ANY footage which is why this is most peculiar, just the wav file so I can edit to the beat.
Once again if there is anything else you can think of...

Client Preview in After Effects

I'm running After Effects ver.8 (CS3) on a nearly new 2.93 GHz Quad-Core Intel Xeon Mac with 6GB RAM. I'm using an AJA ioHD for output to my broadcast monitors. I'm primarily a Final Cut Pro/Avid editor and am back on a rather large AE project after a few years hiatus other than doing minor animated type overlays and such for import back into my editing program.
The project is a little over 2 minutes and has dozens of layers - mostly type, photos and vector files. Very little footage-wise. My question is how to preview the entire 2 minute project at high quality for my clients who are behind me. Is there any way to just render it out in the timeline like you would in FCP or Avid and play it? I can preview sections of it or I can do the whole thing at half-res or skipping frames. I know that I can render out a movie to the finder and then import it back into FCP, but I would think that AE now has a way to render it and just hit "play" in the timeline.
Is there a way to do this? Or should I be getting more throughput with 6GB of RAM? Are my scratch disk settings maybe wrong?
Thanks in advance,
Eddie

No, no and no (mostly). RAM previews are the only way to get guaranteed realtime playback and prevciewing 2 minutes at a time is simply impossible with a 32bit app that can only address 4GB of RAM such as AE is. Sorry, you are really out of luck on that one. The only thing you can do is to try and use the disk cache. Cached frames may play fast enough from disk, if they are fast enough, but there is no guarantees, either. Also note, that AE will weigh your processor performanceagainst the disk performance, so if it thinks it can calculate something faster than read it from disk, it will not cache. Inm addition, caching realyl only takes off if the project is structured accordingly, meaning there are sub-comps that can be cached and are not invalidated with every small change in teh parent comp.

I have no audio when I ram preview or after rendering in CS5.5

I have read all the solutions in other threads but with no avail, I'm still stuck with no audio. I had no problem like this before in CS3 and I'm currently using/learning CS5.5. I've had no audio at all. However, I can hear audio when I click on the layer that has my mp3 file on their by pressing 0 on the number keypad. But when I go on my main comp I can't hear any audio whatsoever when I press the space bar or when I press the RAM preview button. There is no audio even after I render it and yes, I did click on the audio check box in the audio module that has the lossless link to make sure it is on.

The flaw is here:
my mp3 file
Convert it to a WAV or AIFF. Nobody knows what can hapopen with MP3 and AE sucks at using those files even today.

MEMORIA RAM PARA EL AFTER EFFECTS

Hola me gustaría saber que memoria ram utiliza como máximo el after effects. Me quiero comprar un mac nuevo y no se si comprarrmelo con 16 gb o con 32gb de ram.

"El cielo es el límite"
Quien gestiona la memoria disponibe a las aplicaciones es el Sistema Oparativo, el OSX de Apple es uno de 64 bits (desde Lion, con acceso a más de 64GB (teóricamente mucho más).
La decisión la debes tomar desde el punto de vista práctico, si crees que en algun momento, tu trabajo sacará partido práctico de tener más memoria, de forma que te ahorre tiempo (y dinero).
Si al trabajar con After Effects durante la mayoria de tiempo y ocasiones requiere menos de 16GB, el tener 32GB no va a hacer que vaya más rápido, pero si hay tareas o trabajos que podrían beneficiarse, usar más de 16GB, o tienes varias aplicaccione abiertas que consuman esa memoria..., eso si podría justificarse si ofrece una rentabilidad económica.
Tu debes ser el juez e intentar saber cuanta memoria crees que puedes necesitar, puedes monitorizar tu trabajo, el de otros, ...
De qué modelo o tipo de maquina Apple estás pensando, lo digo por el precio de la memoria y la posibilidad de poderla instalar, o no, más tarde, o de fabricantes de memoria, no preinstalada por Apple, siempre bastante más cara.

Extending Render preview in After Effects CC

I have a brand new iMac 27". I've googled to the best of my ability how to extend the render preview. Enabling cache has done nothing. changing the resolution as done nothng. Reducing the quality of the preview has done nothing, in fact it doesn't matter if it's full quality. It stops rendering the preview 100 frames into a 60 second comp. Any help is greatly apreciated.

Interlace Consecutive Frames - in After Effects (CS4)

hi
In Premiere there is an "interlace consecutive frames" option in the field render settings which is useful for resolving field judder problems in certain downloaded mpeg files. Unfortunately I need to use these files within an AEX composition and I can't find an equivalent field setting in AEX anywhere. Can anyone help?
thanks

It doesn't exist. You will have to use plug-ins like RevisionFX' FieldsKit or mimic it by manually combining compositions with doubled framerates, and possibly tricks like using Venetian Blinds to create the interlace pattern.

After Effects CS6 RAM preview seems to now be broken after 11.0.2.12 update

Updated to the latest patch for AE CS6 11.0.2.12.
When I hit RAM Preview, my After Effects just locks up, or has an enormous (minutes) delay if I have multi-processor rending turned on. Info says it is working on background processes.
In fact, if I am using Trapcode Form or Particular and multiprocessor turned on it tends to crash. Since upgrading the version I can't even render that start of a particular scene.
Is anyone else having an issue with this? I have tried it on another workstation in the office and it does exactly the same thing.
My machine is an HP Workstation Z800, Windows 7 64bit, 18Gb Ram, Xeon [email protected] and Nvidia Quadro 5000.

Yes. when using Particular 2.1 I find that if I have MP turned ON it takes forever to set up the processes. Getting out of the MP mode at that point is difficult but possible. Once MP is off everything renders great.
I have no other issues with any operations in the CS6 suite.
This happens on a HP Z820 with all current software/drivers.

After Effects CC 2014 (13.0, 13.1, 13.1.1) and Yosemite RAM preview probleme

"We are aware of one issue regarding RAM preview in After Effects on Mac OSX v10.10: When a RAM preview begins to play, the first several frames of the video will not play the first time through; subsequent loops through the same RAM preview duration will play all frames."
when will it be repaired? in the next update?
thanks

They have said that it is set to be fixed in the next update. Which should be within the month, if I'm not misremembering.
EDIT: I was misremembering. It is an issue that they're aware of, but are still working with Apple to try to find the source of the problem and, thus, the fix.

After Effects CC sluggish "Fast Preview" playback

Hello,
I've recently upgraded from After Effects 5.5 to CC. I've found CC to be very sluggish in many ways, from using the interface itself, to scrolling down my layers using the mouse wheel, to not being able to get realtime playback once I spacebar preview a bit of my timeline.
None of these things were or are issues with After Effects 5.5 which I still have installed thankfully.
My main question is about space bar previewing (foreground memory) bits of your timeline in CC. (Not ram preview)
In After Effects 5.5, it didn't matter how complex my project was, if I hit spacebar to preview it would slowly preview and load, you could see the green render line building, as soon as I was happy I could scrub the rendered green area and if I hit spacebar at any point in the rendered area, After Effects would playback realtime.
This is very important to me because when dealing with little intricate key framing it's nice to be able to playback a given spot within the rendered green area and get realtime playback instantly.
This is impossible to do in CC, it doesn't matter if I spacebar preview or RAM preview an area. When I scrub the green rendered area and hit spacebar to get realtime playback it will never manage to playback at full framerate. The only way to do this is to RAM preview but that defeats the purpose because you have to keep adjusting the work area bar, and it's just not the same as spacebar previewing which gives you more freedom and you don't have to wait for the RAM preview to kick in.
Is their any work around for this? and is their any plans to fixing the general sluggishness of After Effects CC?
Any feedback would be greatly appreciated.
Many Thanks,
Jakub

Mac Pro
2 x 2.4 GHz Quad-Core Intel Ceon
32GB DDR3
ATI Radeon HD 5770 1024 MB
OS X 10.8.2 (Mountain Lion)

Hey Szalam,
I'm on Mountain Lion, the sluggish interaction occurs with or without multiprocessing enabled, my cache is set to 100GB, my composition's are always set to standard classic renderer. Again I also have CS5.5 installed simultaneously and it runs lightning fast in comparison just with default settings. But to be clear, this is not a complaint about actual rendering to file but of not having realtime spacebar preview and the general sluggishness of the UI interaction.
The benefit of realtime spacebar preview is you can preview yourself a little section of timeline and work within that area in almost realtime. If you make a small keyframe adjustment then the green preview line only breaks in that tiny section and it only takes half a second to spacebar render it again, then once you hit stop, the scrub line stay exactly at that frame.
Not having it playback in realtime really does slowdown the process and as Coolbaboon said, it forces you to work in a less intuitive manner.
Again if theirs any current workaround I'm all ears. In the meantime I hope this will be fixed as part of the big overhaul hopefully coming soon. Realtime spacebar preview and a way more responsive UI, like 5.5 had.

RAM preview audio will not play through bluetooth headphones

I am using bluetooth headphones (Jaybird Freedom Sprint) to try and edit audio/video in after effects. However, when I go to Preferences>Audio Output Mapping and choose "Freedom Sprint" and click OK, close the preference window, and it will automatically go back to the default "Built in Output" when I open it back up. It will only play the sound through the Mac Pro tower I am using. Is there a way to get the headphone option output to stay permanently?? Is there a reason why it is not staying selected? Another thing I forgot to mention is that all other sounds work (like iTunes, volume up/down) through the headphones except for the audio RAM preview in After Effects. How can I disable the audio from playing through the tower? Very frustrating!
BTW - the only time headphones actually work is when they are plugged into the tower. These ones obviously can't be plugged in.
Thanks! (Screenshots provided for help)

Thanks! I definitely did try that first... (trying to find a solution with the headphones). You can't find any info about them online/their website. Regardless though, After Effects will not allow me to play the audio output through any other device except for the Mac Pro tower - even playing it through the LCD Cinema Display won't work.
Thanks for your reply

Can't do ram preview, but why?

Hello,
I've been asking this question allready in several forums. I got a problem with ram preview in After Effects.
My PC system:
CPU: AMD Phenom II X6 1055T
Mainboard/Motherboard: GIGABYTE GA-870A-UD3
Graphic Card: Gainward GTX 460 GS 2048MB GDDR5
HDD: WD 500MB
Ram: 12GB SO-DIMM DDR3 A-Data Value 1333 CL9
Windows 7
After Effects CS5
Now when I want to do a ram preview it gives me only about 1,5 seconds, then it stops rendering. Enabling the multicore function will lead to an error message: "Not enough ram installed". When I click on "Details" in pre-settings window in AE, it tells me:
Installed ram: 12GB
Current Ram usage: 0,31 GB
Permissible Ram usage: 0,4 GB
Max. usable memory: 12 GB
Max. allowed memory: 0,4 GB
Minimum required memory: 0,4 GB
Isn't this weird? It seems like AE is not checking that there is 12 GB installed.
PS: In the settings I have set "Ram reserved to other applications" to 1 and "Ram available for AE" to 11.

I have win7 64bit.
C:\Program Files\Adobe\Adobe After Effects CS5\ and all the files are actually in \Support Files\
I've found some talk online about the problem being tied to the Dynamic Link processor. But I have allowed my Dynamic Link manager through my firewall and nothing has happened for me. I've uninstalled AE and had no luck either. I reinstalled it and the problem was still there. I re-installed the latest patch and still nothing. Oddly, I have noticed the Premiere lists my RAM for other programs at 0 now too. I had previously set that to 3GB.
Are there other .dlls I need to permit through the firewall?

After effects takes too long to render, broadcasting time is soon, so I'm in a lot of trouble!!! :(

Hello!
I started to render a pretty easy animation 13 days ago.
The animation is 4.30 minutes long, and there's no 3d involved. Only illustrations from Illustrator and some textures.
After these 13 days of rendering, and finishing 4 minutes, it felt like crashing. So it did.
This animation is for Belgian television (broadcasting time is soon), along with 20 more, so I am in deep deep trouble.
I use my mac pro, from a seagate hard drive.
> codec apple prores hq (this is what the company wants)
Could really use help to solve this problem!!
Thanks a lot
Ellen

Hi!
I agree, something is very wrong with your scene or setup. I would recommend the following actions:
1. Make a RAM preview in After Effects, in full resolution. If you have layers with frame blending or motion blur, make sure to enable the frame blending and motion blur boxes in the top of the timeline so that it shows up in the preview. Also, check the Preview settings window and make sure that no frames are skipped and that it renders in full resolution.
If the RAM preview is rendered as slowly as your final render, then the problem is inside of after effects or with your source files. If the RAM preview is a lot faster than the rendering, the problem is likely in the codec or Adobe Media Encoder (if you render through AMC that is).
2A: IF your RAM preview is extremely slow, try hiding the layers one by one and making more RAM previews to locate problematic source files.
2B: If the RAM preview worked fine, try to render into a different, lossless format – like an uncompressed quicktime or avi file or a quicktime animation with max quality – directly from after effects (In the top menu: Composition/Add to render queue, where you'll likely find some lossless preset). Make sure you have A LOT of free hard drive space before rendering. If this rendering works fine you are left with a lossless file that can be compressed to the apple prores hq-format in any compatible software. For example, you can try opening the file in Premiere and render the Prores from there. With a google search you will probably find lots of ways to render Apple Prores files.
You could also check the resolution of both your main composition and your pre-comps. Avoid using unnecessarily high resolutions, it will only slow things down.
Restarting your computer to clear RAM memory and close eventual bugging processes could also be a good idea.
Good luck!

After Effects Ram Preview Help

Hello. I have recently got into after effects, and haven't had this problem until i deleted and then re downloaded AE (I was having a problem with creative cloud) So, I usually I want to render a 10 second clip, which isn't much, but when I try and render it with RAM Preview, it only renders about one second. I looked at other forum posts, and they suggested to upgrade your ram, but I have 12GB's of RAM dedicated to after effects, and my computer ONLY has 12, so I'm really stuck here. if someone could help me, that would be great as I really can't do anything in AE without a full RAM preview. Thank you.

12 GB RAM isn't much for After Effects. You also need to allow for some RAM usage by the system for it to work properly.
