"I believe" that the issue of internationalization should not influence. I just followed the contents of the manual, that is, I tried to trigger on a clip, NORMAL. But the button goes out as if there was no action involved.

I never mentioned that the localization/internationalization would influence. Please read again this comment. And

(or the same advice in your language version.)

(User xberk in 2015.)

feel for understanding s / internationalization /
ok Only with this referenced post did I understand
it works on the clip located in the media of the project
only (I was applying on the timeline)
thanks for your help.

Good that you seem to have solved your issue. Please study also the "several methods available for adding effects to video. Video plug-ins can be added to tracks, video events, source media files (via the Project Media window), or to the entire video project" (in online Help, "Adding video effects").

@Betovalle

ops ... Now this problem: I did a simple test with a video mp4 and applied the stabilization. Then rendered and the result was a video displaying only black screen. Any suggestions for you to evaluate?

Maybe you had a problem to understand what the error message tells you about adding to an "event". To understand this: Event is called for every item placed on a timeline, that can also be a clip or a part of a clip.
The stabilisation placed on such a clip has to be an add to : rightclick only the videopart of it and choose MediaFX.
On a part of a clip you first have to make a subclip through rigclick and add it the same way to that subclip in order to make a better analysis for only that part.

the clip original before stabilize have this properties

@Betovalle your source media is variable frame rate. You will get better stabilization (and general everything, preview, editing, and rendering) results if it is constant frame rate. If you cannot record constant frame rate, you may like to try converting your source using Handbrake or Avidemux programs before adding them to Movie Studio.

You used Handbrake with wrong settings.
I don't know your sourcesettings before sending it to Handbrake, so publish here the original MediaInfo of your made videos

Ok Now I solved and understand: (I restructured the clip) clip, project has to be the same size (width, height, frame rate)

I'm sorry, but I still can not get what you are doing.
The file from which you published the MediaInfo is made by Handbrake.
But Handbrake cannot make video's, Handbrake is for converting video from files made through screencapture, video app's or camera's and so on.
We like to know wat that first video has for Info before you let it convert by Handbrake.

j-v: is there a difference in the stabilization between versions 15 and 16 of vms platinum?

j-v: is there a difference in the stabilization between versions 15 and 16 of vms platinum?

@Betovalle the answer is Yes, No, Somewhat, Maybe! Movie Studio 15 comes with VEGAS Stabilizer (and I will further reference this as Sony legacy Stabilizer as it is left over from Sony Movie Studio 13). Movie Studio 16, as installed, will come with VEGAS Video Stabilization. However, the Sony legacy Stabilizer is still included, just not shown in the default installation settings.

VEGAS Stabilizer is the Sony Legacy Stabilizer which if I'm not mistaken is actually Mercalli v2.

VEGAS Video Stabilization is new in v16 and is Magix's version.

I think, until there is an improvement in the VEGAS Video Stabilization, the older legacy Stabilizer actually works better, at least on the test I have performed.

the original file was an avi file made of screen video/ convert to mp4 only to quick test without worry /

what should have been done I did now successfully! I consider that the manual was not well written, for those who are familiar with the product. Thank you!
