To quickly get familiar with mocha before you dive into the rest of the manual, here is a breakdown
of the interface and its controls.
Note: Interface Overview uses mocha Pro Interface. Mocha, mocha for After Effects and mocha for
Final Cut may differ in presentation, but their tools perform the same function

    Stabilizing Shaky Camera Footage
    One of the most common reasons to stabilize is to remove jitter from a shaky camera shot. With shaky
    camera footage you are primarily concerned with removing position and rotation data. This means
    you do not have to use the shear or perspective options when tracking. Here is the common method:
    1. Track a static area of the shot using Translation, Scale and Rotation only. You don’t want to track
    a moving object within the shot as this will throw off the stabilization.
    2. Once tracked, switch to the Stabilization tool.
    3. Choose which fields of motion you wish to stabilize in the Smooth parameters. By default, translation
    is automatically selected. In many cases you may only be interested in position stabilization,
    but hand-held cameras can introduce scale and rotation jitter as well.
    4. Adjust the number of frames you want to look for jitter over. A small amount of frames will look
    for tiny adjustments in the overall motion, whereas bigger values in this field will adjust larger
    ranges of motion.

      5. If there is a significant amount of motion being stabilized and you are losing a lot of your picture
      in some frames, try fixing those frames by adding them to the Frame List on the left. Mocha will
      then interpolate the stabilization between these fixed frames

        Locking Down Areas of Motion
        Sometimes you want to be able to completely lock down a section of the footage so that it stays in one
        place and everything else moves around it. For this you can use more aggressive stabilization:
        1. Track the area you want to lock down using whichever of the motion parameters you require.
        Tracking perspective also works for this technique.
        2. Once tracked, switch to the Stabilization tool.
        3. Choose which fields of motion you wish to lock down in the Smooth parameters. By default, translation
        is automatically selected. If you want to completely lock down everything, just choose the
        “All Motion” checkbox.
        4. Adjust the number of frames you want to use to look for stablisation. A small amount of frames
        will look for tiny adjustments in the overall motion, whereas bigger values in this field will adjust
        larger ranges of motion. Again, if you want to completely lock down everything for all motion,
        choose the “Maximum Smoothing” option.
        5. When you play back the timeline you will see the rest of the footage warp and move around your
        locked off area.
