The Problem with Might and Magic (Heroes of Might and Magic 4)

I record the game on Bandicam, but not in OpenGL or DritX format, because it simply does not take it, but in windowed mode and somewhere after 1 hour of the game, it crashes from the game itself, when recording that I have both the recording and the game turned on completely. who knows the other way of recording, through what else? Fraps is not an option, there are even no screen functions, and any others are too dead. The point of the question is to avoid crashes in the window shooting of the program.
