Can anyone suggest what may be causing poor quality audio when I edit my video. I am running Windows XP SP2, with all updates, with an Athlon xp1700 processor and the software I have tried is Windows Movie Maker, Serif Movie Maker V1 both with the same results. The video quality is fine, no dropped frames but the audio, while quite good has little "gaps". If audio was recorded in frames, it would be like a couple of dropped frames every few seconds. I have now tried Serif Movie Maker V4 with very similar results except the "gaps" are filled with high pitched squeaks. I capture the video from a Samsung DV recorder via firewire and my sound card is a PCI soundblaster 128. I also have onboard audio, AC97 but all the video software defaults to the Soundblaster card and doesn't allow me to select the onboard.
BBW, I had tried recording in 12bit and 16bit audio which made no difference. I've just tried playing with the bit rates through the editing software. It's default rate is 32 bit on playback, which does sync with the video. I tried upping it and lowering it but it just speeds up or slows down the audio playback. I cannot select which bit rate it captures at, it just defaults to the settings for microsoft DV.
