Run ZD Soft Game Recorder before running the PC game you want to record. It runs in the background. It automatically detects which PC game you are running in the foreground.
After you press the hotkey to start recording, it grabs every frame of the game, compresses the frame data in MPEG4 format and stores the compressed data to a video file.
It also captures, compresses and stores the audio data of the game to the video file if the audio recording option is enabled. Everything is done in real-time.
The video file is automatically named bases on the executable file name of the game you are recording. Press the same hotkey again to stop recording.
