First off just have to say I love this application. Used it a lot and never had issues with it. That being said I just installed a video computer running resolume avenue (current version) and everything seemed okay, but after about 30 minutes or longer it freezes the current playback. The issue seems to have no bearing on what effects are running or how many layers, just like some strange glitch. You usually have to ctrl alt del and force to quit, and restart the app. The current setup is as follows:
Lenovo PC
I7 3.4 ghz processor
12Gb of memory
2 Radeon HD 4770 gfx cards
1 TB hard drive (app on same partition as OS and clips)
Windows 8 OS
I havent heard anyone having issues with windows 8 but I have never ran this software with anything but windows 7 or OSx for mac. Hope you have some ideas, im stumped.
