I'm trying to put together a recording of a game I've played with commentary I recorded while playing it. I'm not using the most efficient software since I'm running as cheaply as possible. I recorded the game footage using the emulator I was playing with, VisualBoyAdvance. I recorded the commentary with Audacity. I'm using Windows Movie Maker to string them together. The audio seems to be getting more out-of-sync as I go along, in that towards the end of the video, the audio is playing seconds after the corresponding video. If I have the audio play earlier to rectify this, then towards the start of the video the audio is playing earlier than the video. This is giving me a headache synchronising the audio.
Is there any way this can be rectified?
