I have a simple animation for a midterm project; someone walks up and pushes dominoes over. I can set something with physics to knock the dominoes over at frame 125, then play the engine and he will walk up and push the dominoes up easy enough. When I record though, the animation will still show those things happening simultaneously, but the keyframes for the dominoes falling over are recorded at frame 270, a very long time after they're pushed over. How can I fix this?
If your issue is simply that all of your keyframes on the dominoes are starting too late, you can easily fix this by using the dope sheet. Select all of the keyframes in your scene by hitting A (or select just the ones you want by using box selection with B, or circle selection with C). Then simply move them closer to the beginning of your timeline. (shortcut would be G).
