I have been using the Mercalli plugin from proDad since it was introduced, and I have had great success with it. The fact that I could use it as a plugin with my NLE made it very convenient to use, and it worked great. I have used both Mercalli and Virtual Dub, but I have always felt that Mercalli gave me a slightly better final result. Of course that may be subjective on my part, but there are a few others that agree. This past year I decided to go total 64bit and not bother installing the 32bit NLE. As a result I needed to update to Mercalli V2 Pro which comes in 32bit and 64bit versions. proDad has done a great job provide several versions of the Pro stabilizer for the cost of the upgrade (32bit, 64bit and a Stand Alone Version).

John RoFrano has done an excellent job reviewing Mercalli V2 Pro. No sense rehashing what John has so thoroughly already done.

Warning: You may need to alter your work flow if you find yourself needing to stabilize a clip. For example if you split the clip in to two clips each segment will need to have the Mercalli plugin applied. That could result in a different border/zoom for each clip. The seamless flow between the split clip could cause what appears to be a jump cut, because the two clips most assuredly will have a different zoom (caused by the settings and unsteadiness for that unique clip).

In John's video he shows you the zoom change between Mercalli 1 and 2. In my clip I decided to use the borders option which does not zoom. This example allows you to see how much more of the picture Mercalli 2 displays than older V1 when applying an almost exact same amount of stabilization.

In the above video clip Mercalli Expert is applied to the left half of the video and Mercalli V2 Pro is applied to the right half. I used the border option so no zoom would be applied. As you can see the stabilization is very close to matching for each half, but notice how much more of the image can be seen on the right side using V2. Well worth the investment! I was able to upgrade for $111.20. After the purchase it took about 6 hours to get the license key and links to download the Mercalli software.

In the video below Hyderabad traffic was captured on a Sony HDR-XR520. I then applied Mercalli V2, color correction, unsharp mask and a small amount of saturation.
