![]() ![]() The results of using Mercalli with otherwise horrible footage are amazing as you can see from the company’s promo reel. ![]() Supported video resolutions include Standard Definition (640 x 480, 1024 x 764, 720 x 480), High Definition (720P, 1080i, 1080p), and Ultra High Definition (2.7K, 4K). Mercalli also has a simple editor so you can create clips for assembly in other editors and you can export in HEVC/H.265 (mov), H.264/AVC (mp4 & mov), Motion JPEG (mov), and Apple ProRes (mov) and Dolby AC-3 audio is supported. Mercalli has lots of presets for different camera types such as sports cams and forensic cameras, fisheye correction for generic as well as specific cameras (including most GoPro models), and rolling shutter compensation for general and specific cases. On one of my non-GPU equipped laptops the rendering of a 46 second test video took an hour so having a GPU is highly advised if you, like me, are impatient. You can tweak a large number of parameters that affect how things like panning shots are smoothed, how tilting is corrected, and so on, then render the result. Once your clips are loaded into the Media Bin you then start the analysis process which examines the footage frame-by-frame to measure the shift, roll, CMOS sensor response, zoom, tilt, and zoom-in between frames. To process a video you can either drag and drop from Explorer onto the edit window or use the file browser and import formats include mov, mpg, mpeg, mp4, mts, m2t, m2ts, m2v, avi, wmv, mxf, vob, vcd, 3pg, Canopus DV, and Canopus HD. Mercalli, which is only available for Windows, is easy to install and when you run the program it looks for a GPU and if one isn’t available warns you that its performance will be slower and the results less polished. If these are problems that affect your video projects I have the answer, proDAD Mercalli V4 SAL+ software, which smooths video jitter, wobbles, and shake as well as removing CMOS sensor distortions. ![]() You see a lot of this type of subpar content from sports videos where a camera is attached to a runner or a mountain biker while video from drones often suffers from “jello” from unbalanced propellers. Unless you’re using really expensive gear with professional booms or completely stable mounts to shoot action video, you’re going to wind up with footage that wobbles and jiggles often to the point of unwatchability (even with the professional gear, unwanted effects aren’t completely avoidable).
