Pan and zoom of still images - problems

[MikeA]

I have used the built-in pan and zoom (not the FX) for years on still images. It has largely worked well. In the past I noticed a few quirks.
1) If a keyframe was moved, the feature would not properly recalculate the path of the pan and zoom. Instead, it would jerk to position close to the revised keyframe. I would have to change the zoom and then reset it to what I wanted. Then it would be smooth again.

2) Sometimes changes made to a pan and zoom setup were not stored on return to the timeline. I would have to go back and do them again.

And now, in addition to these, I am getting another issue:
3) After completing a pan and zoom sequence, and on playing through the movie on the timeline later, I would see that the programmed sequence was not being followed. On going back into the pan and zoom screen, all was as it should be. But despite this, it had been doing its own thing. Going back into the pan and zoom screen fixed the issue.

All of these are not serious, but they are annoying and cause a project to take longer than it should. There's enough fussy work without having to fix little things like this.

Anyone else had this issue? Any ideas on how to fix?

Hi Mike

I have not noticed a problem and don't think this has been posted before?

And what version of video studio are you using.
I assume it used to work ok in the past so whats changed on the pc.

I have just tried your first issue changing the keyframes, I do not have a problem with that?

The logo says Pro 16.1.0.45 Ult.

I have had problem 1 for a long time. I just tried it, and of course it worked perfectly. But then, it is not a predictable issue. Most times I don't have any problem. The same with the other two - just occasionally. The 3rd issue is a new one I just spotted.

I will be editing today, and if any errors occur I will try to document them.

Just had the first problem happen. I was applying pan and zoom to a still image. I set the first keyframe position and zoom, created a second keyframe shortly after the first, created one near the end, adjusting position and zoom, and copied those settings to the final keyframe. After I returned to the timeline I realized I hadn't copied the settings for the first keyframe to the second (the idea was to stay at the first zoom and position for a few seconds, move to another setting, and keep that for the last few seconds). So I went back in and copied the first settings to the second keyframe. The change did not take effect properly between the second and third. There was a hiccup just before the third keyframe, when the picture jumped suddenly to the settings for that keyframe. To fix it I adjusted the zoom using the handles on the third keyframe, making a note of the zoom factor. I then entered the zoom level into the box numerically. The transition then became smooth. This has happened occasionally to me for years.

Hi Mike

Thanks for the further explanation----Yes I can replicate that problem.

It seems as though the first settings are saved to a cache file somewhere and not overwritten when you alter / update a keyframe, and that seems to upset the whole sequence.

I found that playing the sequence from the Pan and Zoom panel before hitting OK seemed to cure that.
Scrubbing the timeline – that is dragging the curser from Left to Right also seems to work? As though refreshing the settings?

But yes, at first I thought it was self inflicted using the wrong setting.

I can only suggest you drag that curser before closing the panel.

Given a bit of time I will do a few more tests

Thank you for investigation and wonderful to have been found neither crazy nor with a defective computer. In my simple-minded view, a fix for this should be easy by Corel - just refresh the settings when OK is clicked. It seems likely that my second issue - edits not being saved could also be due to the same basic problem and, for now, could be dealt with by scanning the timeline. I will try. The third error, which I have only noticed in the last few weeks with the most current version of VS and its update, seems to be coming from a different source, like the settings are getting corrupted, or least the place where they are read from is (since when I go back into the image the settings are fine).

Hi Mike

Scrubbing the timeline or playing the effect in the customise panel does seem to refresh and set the correct pan and zoom, I guess that’s the work-round.

Unfortunately the problem is not limited to X6 but affects all versions at least back to X3? As you rightly say it should be easy for Corel to fix
