Update your graphics card driver/ configure the settings. Both issues point to generic hardware acceleration issues in AE and Quicktime also. For the latter, you might avoid the problem by enabling the use GDI mode option in teh QT system control panel, but of course it may hamper playback of all QT files...
In addition to Mylenium's advice, I see two troubling settings in your screen shots:
1) Your comp is set to 24 frames/sec. Except for very sophisticated HD cameras -- typically coming with price tags rivaling those of brand-new Corvettes -- the proper frame rate is ALMOST NEVER 24 frames/sec, but 23.976 fps. That fractional difference really does count. We don't know a thing about your workflow or other footage you use, but I have five whole American Dollars that say you have the wrong frame rate.
2) Here's something that's COMPLETELY wrong: your memory settings. You've allocated all your RAM to AE, and have left nothing for tiny little considerations like the operating system and any applications that need to remain open. Thus, you're strangling your machine. You ought to look carefully at this page:
Mylenium thanks a lot for your quick reply I will update the drivers and such and get back to you with the results.
Hey Dave thanks alot I'm a bit of a newbie when it comes to the PC, the file that I showed you was a credit sequence template, however most of my footage have been 23.976, all of which Including the 24frames sequence plays fine on all my macs.
I'll go back and use your settings on the PC and make sure I have allocated the memory based on the chart reccomendations. I'll let you know how it goes ASAP.
Thanks for all of your help, I follow your psots on creative cow!
Unfortunatley still the same issue. I'm stumped
I think its an issue where After Effects is not picking up that I have Ram installed, when i allocate Ram to AE and the resereve applications the settingd reset.
I'm hoping you might have another solution.
I'd try restoring default AE preferences. Look in AE Help, search for preferences, and the technique should be right near the top in a help section called, oddly enough, Preferences.
Well i'm back to square one, It's now saying I have to install quicktime and i'm having the same issues lol.
I'll get back to you once i've solved the issue. If you have any other suggestions I welcome them.
I'm sure its something minor, but for someone who's not used to a Windows file structure it's like searching for a needle in a haystack.
Thanks Dave and Mylenium
i know this issue is from the 29 of January, but if your problem still exist maybe this solution works for you, too.
I tried a lot (install and uninstall After Effects, turn MP on and off, purged my cache, install and uninstall different codecs, convert the footage in different formats etc) and nothing solved the problem with the RAM Preview.
Last week i figured out its my firewall that produces this weird error message. After Effects had all access to the internet and the system, so normally there shouldn´t be any issue with the firewall. All of my friends used the Comodo Firewall as i do... and they had the same problem (not always, sometimes its disappeared and came back).
When i recommended to deactivate or uninstall the firewall, it worked for all of them.
First of all, make sure that your dynamiclinkmanager.exe has access to your system, if its blocked, allow the access. If that doesn´t work, try to deactivate your firewall and try to RAM-Preview again.
Would be nice if you let me know if its working.
Maybe it will help someone in this forum.
