Can you tell us what the separate audio recorder was, the file type recorded, timecode or not, timecode type (ie PAL/ NTSC DF non drop),plus the video file information, including frame rate and timecode type.
Then we need to know the sequence settings including frame rate, timecode settings and audio sample rate. This is the basic information needed to help solve your problem.
Please also think about basic punctuation. Your post is hard to read.
