When SmoothCam analyzes a clip, it analyses the entire clip. This is probably the most important thing to know about the SmoothCam filter. If you move the clip or change the In and Out points of the clip, the analyzed file will still work. Second, the analysis files tend to be large in size, but this process only needs to be performed once. First, it does take time for the filter to go through each and every frame and note the positions and movement of the pixels, however, this analysis goes on as a background process, which means that you can return to FCP and continue working while the analysis process continues. There are several things that we need to know about the analysis file that SmoothCam creates. Once the clip has been analyzed, FCP will use the information during RT playback or render, to compensate for and correct the unwanted camera motion. If you are working on a network where you don't have permission to write back to the folder that contains the source video, then FCP will place the 'analyzed' file in either User > Library/Caches// or Library/Caches//. SmoothCam creates a file containing the tracking information about the camera movement and, by default, places the 'analyzed' file into the folder that contains the source video of the clip. The first step of the SmoothCam process is to analyze the direction of the camera movement by tracking the movement of the pixels in each video frame. SmoothCam uses a two step process to corrected for camera movement. When Apple released FCP 6, they introduced 'SmoothCam' a new filter, whose technology comes from the Shake application. In the past we could either not use the clip or trim it as short as possible and hope that no one would notice. A clip, that we want to use in an edit, was shot hand-held, and of course, there is unwanted camera movement.
