Okay here is a quick update.
I noticed when i advance key frame by key frame there is not a frame change rather its a duplicate frame which when seen in the video makes it looks like a brief pause or studder.
For example, in my movie at frames 1700-1701 they are the same frame twice and this continues for 1706-1707, 15-16, 21-22, 30-31, 36-37, 45-46 and so on.
iMovie must be doing this to the movie but I don't know why.
Serial are you using iMovie as well?
