First, you want to get the best quality from the tape possible. For our Pro SD and Pro HD process we use professional broadcast machines. Our broadcast machines will get the best color and exposure possible from the tape itself. In addition, these broadcast machines can correct tape tracking/rolling issues in most cases.
Below, we are showing the difference between our SD and Pro SD/HD process. The SD process will produce video that looks like the original tape on the left. The Pro SD/Pro HD process with tracking/rolling correction produces video like that on the right.
