>>When I render a default stabilisation of the plugin to another framerate or resolution than the projectsettings after analysing, this is the result:

Can you be more specific.  What were the project settings?  What were the render settings -- render template?  I'm not having this issue with Mercalli 4 plugin but I normally try to render to the project settings.  But I can say that the Mercalli plugin is not entirely solid.  Sometimes unexpectedly the  "ANALYSIS" banner pops up.

By the way, the Deshaker script in V13 looks very good.  But so far, for me, Mercalli 4 is giving good results at the default setting.  

Hi xberk, sorry to jump again in this thread, but I can bring some updates of my tests.

In my case, as I need to mix videos from Sony Cx700 (Full HD 50i) and videos from GoPro Hero 4 (Full HD 25p Wide).
So my project is set to HD 1080-50i (1920x1080; 25,000 fps)
The stabilization I try to do is for Gopro videos, and you are right, there is a difference with the project settings (interleaved pictures) and the Gopro footages (plain picture).
However, sometimes it is working fine, and I've tried to understand what is going wrong. I've also understood that each time you change a small thing in the timeline arround this Gopro video (for example, change the duration of the clip), you'll have to launch again the Mercalli analysis button. If not, the result is bad!
Maybe I should do the test with Gopro videos converted by GoPro Studio first instead of trying to use direclty native MP4 Gopro footage.
I will give more updates when I find more stuff.

Mercalli v4 does not like it if you change the frame rate. In my experience, your should keep your media, project settings, and rendered  output at all the same frame rate.   If you need to mix media of different frame rates or change the frame rate on output, I would suggest  first working with the clips you need stabilized, render out a stabilized version to a suitable intermediate codec (I like cineform, but there are lots of alternatives), then import those clips into your mixed media project and continue editing from there.

Mercalli 4 SAL is great, but the Mercalli 4 plug-in for Vegas Pro 13 is terrible - in my case, it adds verticle judder to the image rather than reducing it.  It even adds verticle judder to a jpg still image - how crazy is that!

With all respect, I still think you guys are doing something wrong.  I get great results from mercalli v4.  Why would mercalli 4 be worse than mercalli 2 (the one in vegas)?   And why would you apply stabilization to a still image?  That is a totally artificial test - not real world usage  - so you shouldn't draw any conclusions from that.

Hi Cornico,

I am happy to try, as long as we all understand that I am not here to defend Prodad, and obviously I am not a software support guy, just another user.

That said, when I look at your footage, it looks like what I get in two situations: 1) frame rate changes, and 2) problems with mercalli interpreting interlacing.  I can MAKE my footage judder & shake by manipulating these variables, and conversely that is how I think you can make it work.

So, we already discussed frame rates: the short answer is media  / project / render should all stay the same unless you do an intermediate to "bake" the stabilisation in .

For interlacing problems I have found that if I put HDV footage on the timeline matched to this footage (60i, upper) I will get poor results and judder in some cases.  BUT if I temporarily change the project to progressive, then let mercalli analyse, it works great, even if I then change the project properties back to 60i upper.  Can you try that too?

I can certainly see that in cases where you want to change to a different frame rate,  that mercalli 4 is more of a hassle than mercalli 2. 

My argument for using mercalli 4 is that I cannot get anywhere near as good stabilization when using mercalli 2, mercalli 2 has to be applied as a media fx to the whole clip (unless you first make a subclip),  and it is slow slow slow.  So for me taking the extra step to render to an intermediate (only in those special cases) really is not a big deal.

The last thing to clarify:  those original videos you posted at the start of this thread are no longer an accurate representation of mercalli 4. Right?  If you set things up the way mercalli wants you can get much better results. Right?
