Sony Stabilize Effect bad... adds "jump"

cimotion wrote on 12/16/2011, 10:19 PM

I submitted a ticket to sony for this but thought I'd throw this out to see if anybody else see's the same problem or if they have a fix. Im on Windows 7 64bit, with the latest vegas build 511.

Question to Support:
Sony stabilize program has an error. 90% of the time when I add stabilization to a clip it does a decent job at stabilizing but i get a "jump". Even if I run the stabilize several times on that same clip and the "jump" will not allways be in the same place. Also sometimes when I removed stabilize media effect, it still had the "jump" on my subclip even though the effect was removed. Sometimes the stabilize will work and I move on. Later when I come back to watch the clip it has many jumps and they are extreme. How can I get stabilized media that's not "jumpy"

cimotion, I think you will solve your jerkiness problems if you follow this principle, "When stabilizing video in Sony Vegas 11 using the internal stabilizer or Mercalli V2, best results are obtained when matching properties of source footage, project properties and render properties. If render properties must be different, render to an intermediate or a new track."

Much more info in this thread: First Look at the Vegas 11 Stabilizer Pay particular attention to post #29 (If I counted correctly).

Please post a confirmation that that this fixed your problem. If not, we do, indeed, need to get Sony's attention on this.

Without knowing what cimotion's footage is, not sure if I experienced the same thing but here's what I did notice: Applied stabilizaiton to a sub-clip (about 8 sec. of 1080p24) of a slow drive-by shot that included a pan. All of Jerry's rules were followed. There was one definite "jump" with smooth motion on both sides of it. Stabilized the same clip in V10 - no jump but motion wasn't quite as smooth.

And this wasn't done as an in-depth test. Just used default settings in both stabilizers. And didn't take it any further. I'll try to see if I can correct the jump in V 11 today by adjusting the settings.

Atom12, Humor me on this... could you go back and check your project properties, source footage & render settings and see if there might be a mixture of 24.000 & 23.976 fps settings?

MediaInfo might help.

Jerry, can't reproduce it now. All project and render settings were consistent, all clips from AF100 23.976. I reapplied the default stabilizer settings to the same subclip and it rendered fine. Closed and reopened project several times and reappled stabilizer to original subclip. All fine.
When I saw this yesterday it appeared to be the kind of jump you see from OIS camera stabilization when it "catches up" to a pan. But not today.

atom12, I generally attribute these inconsistent results to Cosmic Rays striking my CPU just as I perform my render. [grin]

I use that justification as well - much too often. Some software just has better radiation shields than others.

Yup, same problem here when going from 425 to 511. See my post in Abandoning Build 511 for the details. Have since gone back to 425, and yes all settings were exactly the same as noted in this thread.

I experience the same problem in 10e with HDV footage. If I choose to create a subclip and stabilize, I get a jump--usually 2 frames at the end of the clip. However, if I stabilize the entire clip, the jump disappears Since most of my clips are very short (6-10 sec), it's not too much of a problem just to stabilize the entire clip.

For events in which only small portions need stabilizing (e.g. camera bounce, jerk), I find it preferable to split the event to isolate those portions and apply deshaker. It's my understanding that the first and last frames of a "deshaked" clip are untouched, thus providing a smooth transition to the remainder of the event. Also, no zoom.

amendegw, Thanks for your suggestion but yes, my project matches my source footage. Before I even render it out I see the "jump" in the preview window. But also upon rendering to the correct settings, the final rendered video still has the problem.

Also as a note the footage I am stabilizing is already very stable (shot with glidecam) but I just wanted to smooth out the footage even more.

Vegas did a good job when it stabilized but that crazy, unpredictable jump drives me crazy.

The music video I was working on is here.

I would have stabilized more of my glidecam shots except for that "jump" that it gave me.

cimotion,

This sounds like an intermittant problem that some cannot solve by matching Project, Source Footage & Render Settings.

Suggest you submit a bug report to Sony. Top of this page Support->Technical Support -> send us your technical support question

btw: fantastic voice on that young lady. Is she your daughter?
