I have no idea what the heck is wrong with my computer but I used to be running a 1.6 ghz amd processor with 256mb ddr memory and the only problem I had was that I couldn't view complex transitions or video fx very well, and it took a reallllllly long time to render files. Recently I switched my memory and video cards for 1gb of ddr memory and a 256mb graphics card by nvidia. For the first week or so I could view all the media I was editing at 29.97fps at draft quality without any problems. Also when I rendered the files vegas would use about 800 out of 1000 mb of my memory, so it would pop the files out real fast. Now for some reason, only sometimes can I view the transitions and/or it will all of a sudden try to show them but get jittery and just skip over them. This is causing a serious problem because my transitions are ending up in the wrong place since I can't "see" them. Also, it is back to rendering the files real slow, almost as if the memory didn't exist. And for some reason if I minimize the program and try to maximize it again, vegas freezes up and I have to manually close it and restart in order for it to work...this is a problem because popups from the internet come on all the time and screw me over. My computer's properties dialogue says that my memory and processor speed are fine. When I’m rendering and I check the task manager the program is now usually using less than 60mb of the memory which accounts for the slowed render process. My real problem is that I’m working on a pictorial video that’s due in about a weeks time and these issues are causing some major problems as I find myself having to go back and blindly edit the spots that need correction. What do you think? Any feedback would be GREATLY appreciated!
