Video goes black, Audio Continues, but I've already tried everything?
Here's the problem: I am trying to record myself playing sims 4. If I run the game with no lag the audio and video align perfectly, but if the game starts to lag EVEN A LITTLE then when I go into playback the video is sped up a random amount, and when it's done the screen goes black but the audio continues as it should be. It's a common problem so there are a lot of solutions available online.
What I've Tried: I tried that little thing where you change which boxes are clicked for show a recording box and make it blink, no combination of clicked and unclicked worked. Next I closed background programs and put my laptop on a laptop fan or even ice pack, no dice. Then I tried changing the frame rate (fps), because I've heard that this will happen because your computer drops frames. When I check at the bottom of the hypercam window it still says dropped frames 0, but the problem persists. I then tried changing the number of keyframes. I brought my settings down from 10,1,100 (looking down those three boxes on the avi file tab) down all the way to 3,1,5 (and other variations but that's as low as I went) only to get the same problems after about 30 seconds of recording when the game would lag. This used to not be a problem when I played on my old computer but now I've lost the settings I used to play with that and don't know what to do anymore!
What You Can Do: I'd greatly appreciate it if someone could recommend another fix, even just an idea. I'd also like to know if you think Hypercam 3 or an altogether different program would solve this issue. The model of computer I used to use hypercam on was several models worse than the one I use it one now, so I don't understand how the bad computer can "handle campturing the frames" when the good one can't.
