After Effects RAM Preview not showing first 50 frames or so - Mac OS

So I'm on a 2012 iMac, and when i RAM preview, it plays audio but video does not show until about 50 or 60 frames in, its like a glitch or lag thats started recently, so it makes ram previewing from a certain time a real pain as i then miss the exact part i want and it c matches up with video a second or two later, i can't find any solutions, please help!!

As Andrew says, Adobe and Apple are working on figuring this bug out. See the known issues section of this page: After Effects good to go with Mac OSX v10.10 (Yosemite)
If you let the RAM preview loop at the end of its playback and play through again, it should be smooth and issue-free.

Error in After Effects RAM Preview after updating to Yosemite

There is an issue of RAM preview not showing video for the first several frames (a second or so) on the first run in After Effects.
No problem under Maverick.
Which means it has to do with the yosemite System-update.
This bug should really be fixed with some priority!
Apparently, Adobe cannot fix it (or don't want to).
So it's Apple who has to do something!!!

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

After Effects Ram Preview Drops Frames , Using Strangely Too Much Ram

System Specs :
     CPU : Core i7 4770k
     Memory : 16 GB DDRIII
     Graphic Card : GTX 770 4GB RAM
     Storage : 256 GB SSD + 2 TB HDD
     OS : Windows 7 SP1
     Using After Effects CC 12.2.1.5
NOTE : NOT ANY ADDITIONAL HARDWARE IS ATTACHED TO MY PC . NO SOUND RELATED EQUIPMENT NOR CAPTURE CARD NOR ANY THING ELSE
Hi there
As you Already Don't know I'm an After effects Specialist Using it for quite long time . There is an Ancient Problem with CS6 CC versions . I have a short Small size 1080p Video , about 8 MB , I drag it into project panel and then put it into timeline hence it creates a sequence . There are no Effects and nothing added to timeline , just a small simple video . The Strange Problem is when I click "0" for ram preview , The video starts playing and the green bar above timeline starts to fill . When Ram preview Finishes and plays the video from beginning I See there are several frames Between which are not being loaded to Ram ! The video plays RGB color bar instead of main video and when I check the Green bar above Timeline I see that those frames are being dropped and there is no Green bar above them !
I have had this problem several times before but this time it is too important and the problem should be solved . What is obvious is that some frames are not being rendered or are being deleted after render !
Another Strange problem is that when I open Task manager , It shows AE uses around 10 GB ! of RAM when I press "0" for Ram previewing this video !
So there is a Logical explanation here , Somehow when I do ram preview this video it uses extra ordinary too much ram so AE is unable to load the full video (8 MB) into Ram and hence deletes some of frames .
most of my videos have not this problem and use acceptable amount of ram .I've had this issue with some of my videos till now .
Listen carefully : "This has nothing to do with AE preferences or low memory or plugins . because there is nothing wrong with any individual components of may hardware or software . I have far more than enough RAM for a 8MB video . My Memory has no hardware or software problem . I tested them and if there was any problem with memory or other hardware that should have affected other applications . I have the most recent AE version . I have the most Recent windows updates and drivers . I have a Clean virus free system , and as a computer engineer this strange AE problem is rarely caused by viruses , trust me . I have not any hardware instead of ones a normal PC has . I have not any problem with my whole entire system configuration because I have benchmarked my PC with several up to date softwares . I have tested my PC with almost any STRESS TESTING solutions available for really long period of time , 3 days by IDA64 . Not any driver conflict , dll missing , registry problem have been discovered , as I know perfectly how to solve them ."
I asked some of my friend whom are expert in AE . I handed them my videos and Watched ALL OF THEM HAD THE SAME ISSUE ! So the problem isn't related to my Local PC . What i believe is that there is some malfunctioning or miss coded part in AE source code that decides to reserve such a huge strange amount of ram for such a tiny 8MB video . The point is that the AE works fine , no crash or any problem report . So the AE it Self decides to allocate such huge amount of ram and thinks it is correct ! So I think this is a work around that AE developers in adobe are using to bypass a problem or conflict ! by Using more amount of RAM . I think that there might be some miss understanding between the AE and my installed codec . I installed MEGA CODEC PACK on my PC to enable some new codec supports , and so are some of Windows default de/encoders changed to new ones . I think there shouldn't be any problem But there is something wrong between AE and de/encoder modules !
Please any one with any suggestion , I really appreciate your advices .

###UPDATED###
Well thank you guys for your patience ...
as you considered I forgot to mention the codec itself and other stuff ...
The video is in 1080p , 35 sec long , it is a green screen shot , this video is directly downloaded from YouTube and plays perfectly on all tested PCs . here are detailed info :

NOTICE : This video is just for testing the lighting and etc , and so the Sampling and other specs are not considered for broadcast .
I think you hit the point ! Thats K-lite codec pack installed on every machine which the video is tested on ! The point is whats wrong with it ?! I have had never ever any problem with this codec pack !!!
The deadly question : So what are the alternative ways to work with codecs that AE doesn't support ?! because installing codec looks simple and sufficient !

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.

After effects ram preview video playback issue

Greetings -- I have Mac Pro 2.93 GHz 12 Core with Nvidia Quadro 4000 & 24GB Ram.
During ram preview playback, it seems as though the video isn't refreshing fast enough in the display -- meaning its almost as if I can see the refresh on the top/bottom half of the frame happening separately. It's a bit diffucut to describe, actually. This does not happen with the same clip in Premiere, just AE.
The rendered video is fine and plays in QT/VLC, etc. without issue, it's just ram preview and is very distracting.
Any help woul dbe greatly appreciated!

Adobe After Effects RAM preview crash

My computer specs:
Processor: AMD9(Quadcore) A8-5600k APU with Radeon HD Graphics 3.60 Ghz
Memory: 8.00 GB (7.40 Usable)
64 bit OS and AAE CS6 is 64 as well.
(I also updated my graphics card driver to Catalyst 12.8 and it still crashes.
Can someone help me solve this problem with it crashing?

Are you saying that After Effects closes when you RAM preview? Does it pop up an error message? How far into a RAM preview? How are you initiating this RAM preview? What kind of footage are you using? What effects are in your comp? Does this happen in every project? Has it worked before without crashing? What EXACT OS are you using? What is your EXACT version number of After Effects (11.0.2?) What are your memory and multiprocessing settings?

After effects layers do not show

Hi can anyone help me,
I've looked around for lots of tutorials and nobody seems to have this simple problem.
When I create a layer in CS5 it dosnt show the layer. Just a box - usually black.
So, lets guide you a bit through the problem.
I load after effects up.
I click on new composition - I leave all the settings as default.
I click ok.
(It dosnt matter what back ground color I select, the screen is always black when I have clicked ok).
No matter what I do from here nothing happens.
If I click the txt Icon and type something, no matter what color txt I select it cannot be seen.
If I then click the selection tool a box appears around where the txt should be so it is definitly there - but no matter what color I select this is what happens.
If I then click on new layer (again leaving everything defaulted) I get a new layer but I just get like a wireframe X across it.
This happens no matter what I do.
The only way to change this is if I mess around with the roto brush and then go back to the original compisition box I can see my txt against a white and grey checked background!!!!
Can anyone help because ive been trying to use since installing 2 days ago!!!
Thanks in advance.

It sounds like you've put the Composition panel in Wireframe view mode.
The reason that using the Roto Brush tool makes a difference is that using the Roto Brush tool forces the Composition panel out of Wireframe mode.
I'm going to guess that this happened because you're new to After Effects and you started choosing menu commands and clicking buttons just to see what they did. The problem is that doing that can get you into situation like this one.
I recommend beginning here and working your way through the getting-started materials:
http://blogs.adobe.com/toddkopriva/2010/01/getting-started-with-after-eff.html
It'll save you a lot of headaches later.
By the way, the Roto Brush tool is actually one of the trickiest and most advanced features in After Effects. I strongly recommend against using it until you've familiarized yourself with the basics.

Thumbnails/Previews not showing on tiffs viewed on Mac

I have a client who is asking me why the tiffs I'm supplying him with don't have thumbnails/previews. He's working an a Mac and has had to resave the files in order to create previews. I haven't been able to answer his question. Any takers? TIA. PShop CS4 / Windows XP.

Well, Photoshop does offer the ability to choose not to save thumbnails/previews... Check Edit - Preferences - File Handling. What's your setting?

After Effects RAM needs 2 or more frames to playback

ADOBE,
IT'S TIME TO FIX THIS ****, IMMEDIATELY!
I read a couple of forums dated months ago. This problem needs to be in an update immediately, goddammit:(

If this is the RAM leak that's been mentioned before that happens in CC 2014 when scrubbing the timeline with audio, the fix is in an update that's coming within a month or so. Personally, I would like them to release it only when they're ready so that the update doesn't cause more bugs.
In the meantime, you can work in CC instead of CC 2014 to do any audio scrubbing you need to do. (You can Save As CC, if you need to get a CC 2014 project to be compatible with the previous version.) This bug should not be interfering with any your work as the issue is not present in CC. The previous version of CC is available from the CC app as shown here: Creative Cloud Help | Install, update, or uninstall apps

My After Effects re sized after a ram preview in full screen and is stuck like that.

What are the pixel dimensions of your monitor?
You can reset the workspace to its default by deleting your preferences folder.
Information on finding and deleting the preferences folder can be found here, in After Effects Help:

MTS file preview not showing in Elements 8

I am trying to use Premiere 8 to edit my AVCHD files from a Panasonic camcorder. The files are MTS format and in Windows 7 explorer the file icons show a preview of the first frame as you would normally expect.
However in Premiere 8 organiser the preview does not show and all the files show a generic "filmstrip" icon so there is no way of identifying which clip is which.
If I drag one of these files into Premiere 8 editor, the first frames show up normally in Sceneline and it appears to be possible to edit the files OK.
Is this normal behaviour for Premiere 8? I have to say I am not too impressed with Premiere (which I have only had for a few days) as it keeps hanging my laptop (core i7 4GB ram Windows 7 64 bit)
Any sugggestions anyone?
Peter

I have just found a work-around to my own problem.
If I select all (CTR-A) then R-click and choose "update" it then shows all the previews.
Wierd!
Peter

In After Effects, it says NOT Realtime and the video is really slow

I'm editing a clip in after effects and the video preview is really slow. I also says in the preview section, "NOT realtime".

How, exactly, are you initiating the preview? Are you using RAM preview?
