Bug Report - Image Stabilization

Click on a video obect and then rotate it 180 degrees.

Now, go to the Image Stabilizer. You'll see your video rotated 180 degrees in the preview window. BUT, when you draw your frame for stabiliztion, the program uses the original object, not your rotated image!

Since, I'm reporting a bug, how about if Magix simply writes "More stabilization, less stabilization" on the radius and temporal sliders?

And a request for enhancement: When you use Image Stabilization, if you happen to have the Key Frames showing, it takes "forever" for the program to finish the stabilization process because it has to draw in a thousand key frames. How about delaying key frame redraws and/or moving that to a background thread?

Just a brief comment on your report of the Image Stabilizer not working on images flipped 180 degrees. I think that makes sense since the stabilizer needs to work on the "original" footage in its "best" version. (If you try to use the stabilizer when having Preview set to anything other than Full Resolution, it will fail. A flipped image is NOT the original footage in its "best" version.)

Clearly, the solution to your problem is to stabilize first, possibly then Preview Render that section and then rotate the image.

I think your suggestion that the settings on the Stabilizer ought to be more explicit is a good one, though I confess my very limited use of this facility in VPX has always produced reasonable results without too much human input!

I agree. It does make sense to do Image Stabilization first. Magix should say that in the manual.

I agree that the IS needs to work on the original footage first. So the Preview should show the original, not the modified image. (I spent an houir trying to figure out why it wasn't stabilizing the image because it was showing the modified image in the preview window!)

And we're agreed that the Engineers need to step back a bit and stop talking in terms of "radius" or "temporal," and instead, just tell us in plain language what the end effect of chaning a setting will be.

Having said all this, MEP is an amazing piece of work. In another post, i commented on using a VST de-esser. I got to thinking that there must be a way to de-ess just one track (instead of the Master channel). Sure enough, Magix already had a way. "If you can think it, Magix can do it."
