AE CS4, Kona 3 and Half Res RAM Preview.

Hi,
I am having a very annoying problem trying to RAM preview in AE CS4 at half res/50% and below.
My system configuration is
MacPro 2008, 16GB RAM, 8800GT.
I am running AE 9.02 on 10.5.7 and am not using the AJA CS4 utilities as they create some problems on my workstation, AJA Kona3 driver v7.1
I am outputting and HD SDI signal to HD SDI monitor, with the AE preference video preview selected on AJAKona 1080i25 RGBA. (Full HD comp of course) While at Full/100% everything is working in Realtime and I have my full HD preview running on my monitor, as soon as I choose to preview in Half Res and 50% size, everything runs at 6-8 fps. IT IS IMPOSSIBLE TO WORK LIKE THIS! and is very frustrating.
In a comp which is standard PAL all works fine in Full/Half/Quarter etc...
My AJA control panel output1 is set to 1080i and the secondary output to 625i and is connected to an SD monitor in order to have both HD and SD monitoring but this should not be a problem....
I am desperately looking for a solution for that and any help will be appreciated.
ThanX in advance and happy holiday season to all.

Cool, I tried that as well and it worked.
Then I remembered that I had had to stretch things out originally because when I imported them they played at double speed. So I bumped my preview playback from 29.97fps to 15fps and un-stretched them. Then I created the preview and the preview played right, and also the RAM save copy played right. So that was it. I just had to change my preview speed and render speed to 15fps, which is apparently the speed of the video from my input device.
Thanks a million!

Audio Tempo is Wrong and Slow in RAM Preview

I am trying to get After Effects and audio to play nice, but I am having problems. I exported 2 minutes of audio from GarageBand (no compression) and brought it into AF. I have a new composition (set at 29.97) and my Preview panel is also set to 29.97.
The problem is that my RAM preview sounds wrong. Not only does it seem a hair slow, it also sounds like the tone is lower throughout the piece (one may cause the other). When I render a movie, the audio sounds fine. Any thoughts?
I have an iMac i7 with 8GB RAM and I have set my buffer size to 4096 in the AF preferences pane for Audio Hardware (is there any reason not to crank this all the way up?). I am running Mac OS 10.6.3.

check the audio hardware settings in your prefs and in your system's Quicktime settings panel. Sounds like you are having audio buffer delay set too long/ buffer size set to high, resulting in the playback getting out of sync.

There are no such controls for the MacOS and sound cards are rare in the Macintosh, usually only associated with big audio apps like MOTU (but I've never used any of those products). The non-expandable iMac does not have a sound card at all. You gets what you pays for in the iMac.
If an audio track cannot play well or properly in AE, it is my experience that it's easier to use a lower rez version of the track than to fight what is going to be a losing battle with AE's audio preview paradigm. Doesn't always work, though, which is why I can only rely the audio waveform display for placing accurate audio hooks.

After Effects CS6 error: RAM Preview needs 2 or more frames to playback - any ideas please?

Hi everyone,
I'm running After Effects CS6 (11.0.4.2) on a MacBook Pro 2.8Ghz with 16GB RAM (Mac OS 10.9.4)
As a test, I created a 3 and a half minute Sequence in Adobe Premiere CS6, and then imported this into After Effects CS6, and placed it on the AE timeline.
This footage involves a couple of 1920x1080p footage movies, some psds and a large number of JPGs exported from two videos arranged as a sequence in two layers in Premiere, one on top of the other. So all in all for a Premiere / After Effects file I'd say it's reasonably heavy.
I then did a RAM Preview with Multiprocessing switched off - the 3 and a half minute sequence loaded into RAM, taking about 1min 30seconds, and played back in realtime at 25fps. This worked fine with 3,4,5 and 6 GB RAM available to other applications in the Memory Preferences. All things considered I think this is quite good. I can make changes, reclick the RAM Preview icon and my changes load into RAM and it previews ok.
My only 'complaint' is how long the RAM Preview takes to load up the whole thing.
I've been reading up on Multiprocessing and decided to try this to see if I can speed up the time it takes my RAM Preview to load up.
So I looked at some recommendations from Adobe and read information on various forums including this one.
My settings in the Memory Preferences are currently
• 6GB reserved for other applications
• Reduce cache size when system is low on memory - unticked
• After Effects Multiprocessing - ticked
• Installed CPUs (processor cores) - 8
• CPUs reserved for other applications - 6
• RAM allocation per background CPU - 3GB
• Actual CPUs that will be used - 2
This combination takes about 25 seconds to load up my 3 and a half minute sequence which I thought was pretty amazing.
I then pressed the stop button and then the play button - so now just playing the sequence briefly.
And also added a new layer - into the timeline - just a simple shape.
Then I tried a RAM Preview again.
I found I could load up part of the sequence but not load the whole thing into RAM.
I kept trying to get a RAM Preview and got this message
"After Effects error: RAM Preview needs 2 or more frames to playback" which seems to prevent RAM Preview from working.
Eventually I quit and restarted After Effects and the problem went away temporarily and then came back when I tried again.
I tried various changes to the Memory Preferences - trying 3GB available for other applications. This gave 13GB of my 16GB RAM to After Effects.
This made it take slightly longer for the After Effects error to appear but it still appeared.
I tried ticking Reduce Cache size in the Memory Prefs - the After Effects error still appeared, so having read this is supposed to make the issue better I now leave it untucked, but as far as I can see ticked or untucked, it makes no difference, the problem remains.
I've since tried -
Making 2,3,4,5 and 6 CPUs available for other applications.
Changing the Background RAM allocation per background CPU to 0.75GB, 1GB, 1.5GB, 2GB and 3GB
Lots of combinations.
But in the end, I always get the "After Effects error: RAM Preview needs 2 or more frames to playback" error.
It might take less or more time for the message to show up, depending on the combination of settings, but in the end I always got the same message appearing.
And I notice that I can RAM Preview less and less of the timeline. i.e. it becomes more blue than it does green and will load in only a small section of the timeline as opposed to the whole thing.
Reading further, I tried Edit > Purge > Image Cache and Edit > Purge > All Memory but still get the error message.
I also tried ensuring there were no other applications running e.g. Safari or Chrome or Firefox. And certainly not Photoshop or Premiere etc.
Reading even further, I tried two Memory management applications - 'Memory Clean' and 'Purge.'
Neither has had any effect - the After Effects error still appears.
Then I went back into the Memory and Multiprocessing Preferences.
I unticked Render Multiple Frames Simultaneously. And now the RAM Preview loads the whole 3 and half minute sequence in entirety, taking about 1 and half minutes to do so. It's working as perfectly as if I'd just quit and re-opened the application.
Then I went back into the Memory and Multiprocessing Preferences.
I reticked Render Multiple Frames Simultaneously.
The chose Edit > Purge > All
And tried a RAM Preview again. It loaded up in 25 seconds, but then, as previously, the error message came.
I tried Edit > Purge All - no effect.
And I tried going into the Media and Disk Cache Preferences and clicked Empty Disk Cache - still the problem remains.
I understand from my reading that After Effects CS6 11.0.2 was intended to fix this issue but I'm on 11.0.4 and as far as I can tell, I still have it - assuming it's the same thing.
As far as I can see, not using Multiprocessing allows me to work without these errors but take a bit longer to load the RAM Preview.
However I'd like to be able to use Multiprocessing as it seems it can potentially speeds things up quite a lot. I realise I could just not use it and AE would work, but I'd rather be able to make use of a feature of the software if possible, especially if it will speed things up and make optimum use of the my computer's hardware.
I've downloaded a trial copy of After Effects CC 2014. I'm still testing it but as far as I can see the RAM Preview error appears in this version of AE as well, but can take bit longer to show up in my experience.
Thanks everyone - if anyone has any thoughts or advice I'd appreciate hearing your opinions.
Kind regards,
John

You need to have much more RAM reserved for other applications and more CPUs reserved for other applications. Your current settings are crippling your performance.

After you have adjusted your settings according to the recommendations on those pages, restart your computer and try again.

Shrinking ram previews, even with All Purged!

Hi there,
I had the same problem with AE ram previews on my G4 Powerbook that I am now having on the MacBook Pro which replaced it.
What happens is the ram previews get shorter and shorter. I have two gigs of memory, not a ton, but enough for at least a minute and a half of ram preview time at half resolution (D1 project). I just opened a project, loaded up a ram preview and it loads well over a minute and a half. Then what happens is I keep working and creating new portions to ram preview and little by little the ram preview time gets smaller and smaller. Before long, I have a 20 second region selected for ram preview and it only loads 2 seconds.
If I Purge All I will then get about 30 seconds of preview time, but soon after, it gets down to a second, and sometimes just a few frames. I have to quit the program and start it up again to get the full preview time... :(!
Because this exact same problem happened with my last Apple laptop, I assume this is a problem not with the computer, or the particular memory, but with either AfterEffects, or some of the other software I have on my computer, which is Logic Studio, Flash, Illustrator, Photoshop CS3 and a bunch of smaller apps. But I really can't believe it's any of the other apps... Anyway, that's why I have written. To see if anyone else has encountered this problem, or heard about it.
Thanks so much!
Again, I have a MacBook Pro
2.2 Ghz Intel Core 2 Duo
2 GB 667 MHz DDR2 DRAM
21 GB available disc space on the actual computer
Mac OS 10.4.10
AE CS3 8.0.2.27

Thanks again! I really really appreciate your advice.
The format I have been using was quicktime DVC50 NTSC exported directly from FCP. And, again, this behavior is identical to the way AE behaved on other projects and an earlier version of the OS like 5 months ago... It's really since I upgraded to the latest version of AE. But I have been considering upgrading to 10.5 for a while now. Maybe now it the time... It's worth a try.
I have purged the media cache. Again, it will free up some portion, but not all, and afterwards this "sticky filling" starts to happen much faster.
Of course, after posting the blog AE behaved perfectly! Just to make things more strange! Hopefully somebody will have heard of this problem and know how to solve, or at least can offer more clues.
Thanks again for your great help, Mylenium.

RAM Preview/Renders begin after long delay.

This problem began last week. Suddenly, my RAM Previews and renders cause the spinning beach ball of death, which will last anywhere from 1-3 minutes before the actual RAM Preview or render process begins. The longest being 5 minutes, but that's only happened once.
I'm using a Mac Pro with 8GB RAM, 2 x 3 GHz Quad-Core Intel, OSX is current build at 10.5.7. And, I'm using CS4 AE.
So, what could be causing the atrocious delays before beginning the Previews and Renders?
Under preferences, I enabled disk cache, with max at 3500MB. The folder is located on an external drive connected with 800 Firewire. It's been set like this for a while without problems...
Conformed media cache is set for the same drive.
For memory prefs, I have:
Total AE mem usage at 6.5GB, other apps have 1.5.
Render mult frames simultaneously is checked, the longer RAM preview/faster rendering knob is set around midway point.
Hopefully I didn't leave anything out. Thanks for the help in advance.

Yes, it does happen in all of my projects.
The fonts are fine. I just created a new project, typed a regular text layer with a Times, and even that RAM preview took over a minute. The render was the same.
Well, lookee there. Just unchecked the option for rendering multi frames simultaneously and it instantly begins both processes.
Thanks for the help. Hopefully this doesn't crop up again.

No realtime playback during RAM preview

Ever since I upgraded to the newest MacPro, AE has been unable to play a RAM Preview in realtime. Even during the most simple of compesitions, RAM preview fluctuates between 20fps and 59.94fps and will never "lock in" to realtime. Resolution is set to full and zoom is set to 100%. We have compared all the settings to other, less powerful, machines in our studio and still cannot make it play realtime.
Mac Pro 2 x 2.66 Ghz - 6 Core intel Zeon
24 gb Ram
30 inch Apple Cinema Display
ATI Radeon HD 5870
OSX 10.6.6
Kona LHe 9.1
AE 10.5.0.253

I'm guessing the problem is with your Kona card. AJA has been having issues with CS5.5 and they just released updated drivers and have split the Adobe app plugins into their own installer now on the Windows side.
Unfortunately, you say you're already using the Kona 9.1 drivers so you're in the same boat as me with the poor playback in RAM previews.
Removing the Kona card instantly put my RAM previews back to normal, but it's not a proper solution.
Here are some tips I received from AJA support on this issue a few days ago:
OPTIMUM AE Settings for best performance:
Make sure the AJA video preview setting matches the sequence.
Use a RGBA video preview setting and not RGB 10-bit.
In AE preferences -> video preview set Output Quality to Faster.
Go to Project Settings -> set color settings -> depth and set to 8-bits per channel.
Make sure you are viewing at 100% during playback.
I just put the Kona 3G card in last week and CS5.5 instantly had playback issues in both AE and Premiere. I got the 9.1 drivers AJA released this week and everything was fine after that! Halfway through a project yesterday, my RAM previews started lagging again. I'm working with AJA to resolve and if I get it figured out, I will post the solution here.

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.

Only get 1 frame or green background in RAM-Preview AE CS5.5

Hi All,
I've been working with AE for a few years now, and nothing like this has ever happened to me before:
I have a batch of quicktime videos (.mov)(stats are 1080 @24p) that play just fine outside of AE or Premiere. But when I stick them in and do a RAM-Preview, I get only the audio and 1 frame. If I scroll through the video I may get another frame or 2 if i'm lucky, or a dark green background. I have no idea what could possibly be doing this. And it happens in Premeire Pro CS 5.5 as well.
Stats for my mac are 4 gb of RAM and running OSX Mavricks

Codec is AAC, H.264, 2 Channel Audio, etc.
Opening up a file with VLC gives me 516 streams ( ! ) with
Stream 0 having Audio | MPEG AAC Audio (mp4a) | Stereo | 48000 Hz
Stream(s) 1 - 516 having Video | H264 - MPEG-4 AVC (part 10)(avc1) | 1920x1080 | Frame rate of 23.9744...
Some, however, have the (correct) decoding of Planer 4:2:0 YUV, as of which I believe this causes the Purp/Green colors & sometimes dropped frame.
Edit: (More Info)
Due note that the movies where recorded as AVCHD, then opened into Quicktime and then saved as a .MOV for greater flexibility with different programs.
Would it be worth it to try and find the .MTS files again, and use those?
Or, if they have gone missing, what would I do anyways?
Thanks.

After Effects CC not saving ram preview when switching to different tab.

Okay so just recently upgraded to CC and have been experiencing some ram preview problems.
What happens is I will do a ram preview, watch it, then switch to a different window (Chrome, word, etc)
and when I go back to AE and do a ram preview it does it all over again even though i haven't changed anything in the comp.
I dont believe this was a problem in CS5.
Any help on what settings i should check or if its a coding problem would be appreciated.
Some specs:
16gb ddr3 ram
AMD FX-6300
Radeon R7 250
Everything Program/Cache is on SSD and the project file/video files are on Ext HDD

Okay it's kind of fixed. (it isnt deleting it like it used too)
i cleared my cache which was about 30gb, but I still had about 20gb of free space when i cleared it
but Now I am getting some crashes and other stuff (colored bars, i already read thats getting fixed though)
Do you think lowering the CPUs used to 3 will help?
Ill update if it does it again when the cache is getting close to full

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.

RAM Preview Problems in After Effects CC

AE CS 6 RAM Previews work, but two problems to report with AE CC on the same computer. Possibly two faces of the same problem.
1. Having QuickTime Player open while doing a RAM preview makes the RAM preview stutter. I quit the player, and now the RAM preview plays back without dropping a frame, though Info palate shows "fps: 24 (realtime)", but the RAM preview playback is slow: ie, a tenor sounds like a baritone.
2. A RAM preview that looked and sounded fine last night, is now playing back slowly (tenor sounds like a baritone), though Info Palate shows "fps: 24 (realtime)". I have no other applications open. The only thing that changed is that I quit AE, slept the computer, slept a little myself, and then launched AE. Trashing the cache files (manually), rebooting, relaunching and re-RAM-previewing creates a functional RAM preview, so I assume there is some problem with the cached files or the retrieval of them.
Is anyone else getting either of these? If so, what is your system configuration?
Also, I posted on another thread that Quicktime import/render works with AE CS6 on this computer, but AE CC can not import, play, or render QT reliably (without throwing error messages). Perhaps all of this is part of the same problem.
Thoughts?
Cheers,
Benjamin
CS 6 CC | Mac OS 10.8.4 | MacPro5,1 | 96 GB Ram | PROJECT & MEDIA drive: Mercury Accelsior > 500 MB/s read/write | CACHE drive: Mercury Accelsior > 500 MB/s read/write | Nvidia Quadro 4000 Mac | CUDA Driver: latest update | Wacom Intuos 5

96 GB RAM is accessible in 10.8.4 on my machine according to OWC. I'm working on a stereoscopic 4K project with large files and hundreds of layers. I regurlarly render with AE MP while working with huge files in PS, and am glad to see the % of RAM AE uses displayed in my render cue between 3 and 60%.
I have 12 processors (24 with hyperthreading)
I have reserved 10 for other applications leaving 14 for After Effects
4 GB per x 14 = 56 GB for AE. leaving 40 GB for everything else
I've played with what and how much I have allocated being sure to keep the CPU counts even, but this does not fix the RAM preview problems described above. Any other suggestions?
Thanks,
Benjamin

AE CC 2014 Mercury Transmit Ram Preview with AJA flickers

Hey Everyone,
I have installed the latest AJA drivers and plugins and enabled Mercury Transmit preview in AE but when I render the preview the output flickers. One frame is normal the next is darker, normal, darker etc.
Has anyone got this working yet ?
Nic

Hi Nic,
I'm not familiar with that error message. It's probably generated by the AJA Preview plug-in. Can you post a screen shot?
8-bpc vs. 16-bpc does not always affect the appearance of the comp, it depends on the source material in use and how you are manipulating it. And in any case you can always switch between 8/16-bpc to get better performance when necessary. Keep in mind that switching color depths will invalidate any cached frames.
Some facts about RAM preview playback performance with video preview in After Effects:
Enabling video preview of any form uses the CPU and memory resources of your computer, and when these are in low supply can eventually result in slow frame rates during RAM preview playback. This is because as the frames are played they are transformed on-the-fly (no caching) to the format of the video preview device. The higher the memory requirements of the frame (resolution, frame rate, color depth), the sooner you'll see the playback frame rate slow down. After Effects does not have the option of dropping frames during playback to maintain playback speed, like how Premiere Pro does.
The AJA Preview plug-in does this frame transform more efficiently than After Effects, because AJA has optimized their hardware-based playback pipeline to perform these transformations. It can still eventually be impacted by performance issues. Also, the AJA Preview plug-in currently has some limitations with scaled comp resolutions and color management, so there may be times when you may want to use Mercury Transmit for video preview instead.
When you are having problems with real-time playback with RAM preview, regardless of whether or not video preview is enabled the answer is always the same: reduce the resolution, frame rate, and/or color depth of the comp. The Resolution and Frame Rate/Skip controls in the Preview panel are intended for you to do exactly that, and the Shift+RAM Preview Options allow you to define two different sets of controls so you don't have to fiddle with those options frequently. Also, enabling color management will slow down RAM preview, as it does an on-the-fly transformation to correct the colors for screen display, similar to video preview. You can either choose View > Use Display Color Management to disable just the display correction, which will likely result in wrong color appearance of your comp, or disable color management in the Project Settings dialog altogether. Re-enable color management when you want to check the colors.
Otherwise, the best solution for slow playback in After Effects when you have a memory-intensive comp is a more powerful CPU and more RAM.

After Effects CC crash when RAM preview

Hello,
I have project im working for 2 weeks. It was all good till yesterday. Today I opened and tried to Ram preview it, but either it crash and close or if I click the space bar to watch in the midle of ram preview it opens a warning window, with nothing inside (see attach) and I can not close it or do anything else.
Im running a Windows 8 in a IntelCore i7 4770 3.4GHz 3.4GHz, RAM installed 16GB - Video - NVIDIA GFORCE GTX 660
I just can not work this way, I need to finish this program and I can not find a good explanation for this crashes.
Thank you.
Edit: insert attachment

Hello Mylenium,
First I apologise for my poor english, see it is not my native language.
Now, I have tried that and it didn´t do me any good.
I have backups, however Im not sure if "save incrementally" means the same thing.
Plus, I have managed to RAM preview going by parts, however I don´t feel like that must be the only way to do it.
Thank you,
Eduardo

QuickTime Player open while doing a RAM preview makes the RAM preview stutter

Update: Ooof. Having QuickTime Player open while doing a RAM preview makes the RAM preview stutter. I quit the player, and now the RAM preview plays back without dropping a frame, says it's 24 FPS, but the RAM preview playback is slow: iE, a tenor sounds like a baritone. Trashing cache, restarting, no luck.
system details in my profile.
ug. I just updated to 7/0/1 DL. Hope that didn't make things worse.

HI Tim. In a rendering, tweaking marathon for delivery. Awaiting progress bar now, and will unplug my monitor and thoroughly reinstal after delivery.
Regarding QT player, it is open with a reference movie that is not called upon by After Effects. I have not had a QT in my project since this problem arose a few weeks ago, just PNG sequences and .AIFs.
Multiprocessing is enabled with 4GB ram assigned to each thread, leaving 10 processers avilable for other applications.
I did just see 83% of my 96GB of ram "in use" while AE was divvying up tasks between processors on a failed PNG render. Quit, trashed cache files, and now it's rendering using 6% of RAM.
Happy to start a new thread... what would I call it?
Cheers,

RAM preview crash when Time Remapping applied

Dear All,
I've recently upgraded from CS6 to CC 2014. Unfortunately I'm experiencing a strange problem and I couldn't find an answer yet.
Whenever I Time Remap a footage (Canon 7D, H.264, MOV, straight out from the camera) and try to RAM Preview, AE crashes.
There is nothing in the Comp, no effects, only 1 video with just the Time Remapping applied.
My system is:
Mac OS 10.8.5
3.4 Ghz
32Gb RAM
NVIDIA GeForce GTX 680MX 2048 MB
After Effects CC 13.2
Any thoughts and help are much appreciated!
Many thanks,
Laszlo

Hi Rick,
Thank you for your reply. I don't really want to transcode the footage because it takes time and I never had to do that in order to edit it in AE.
I did a test with the same footage, same settings etc. on my laptop which is on Mavericks and it did work. So I'm thinking it must be the combination of Mountain Lion and After Effects 13.2. Very strange.
Probably time to upgrade the OS.
Thanks again for your time!
All the best,
Laszlo
