In case you've don't receive notifications from Prodad, two days ago I received a notice about their video optimization product Mercalli SAL V4 + (that's a plus sign on the end). Upgrade cost me $130.50 (ouch) after entering coupon code in checkout: xmas2014-25. That coupon code probably won't work for you, as I now see Prodad has come out with another notice that the Christmas code doesn't apply to Mercalli SAL V4 + because there is already a 25% discount on it. I guess I was lucky.
You can download a trial version, which puts a Prodad logo on the stabilized media. [url]http:\\www.prodad.com\[/url]
Some of the new items I noticed so far: There is now lens correction, dynamic stabilization, noise/sharpen filter, greatly improved CMOS analysis and correction. I was astonished at the results. This makes Mercalli SAL V3 obsolete. With dynamic stabilization, the amount of zoom is kept to a minimum. Instead of applying one zoom level to an entire clip, V4 will adjust the zoom so that the parts of a video that are the least shakiest aren't zoomed in to the same level as the amounts needed for the shakiest parts. V4 produces much sharper and smoother video than V3.
You can do batches. After adding one or more videos to a batch, you can then click the button to export the stabilized media. Mercalli will analyze each video automatically and apply what it considers to be the best settings before the export. This feature is in V3 as well, but now the results are better.
Happy editing.
