Filter Pan and Zoom. Troubleshooting.

[Kolobokk11]

I have long been using the program. I like the filter Video Pan and Zoom, if not a big BUT.

If the clip you select multiple control points pan and some of them coincide with the center, it is impossible to capture the crossing point for the desired position correction frame, since the engine is the player immediately jumps to the first control point. If the pre-shift frame with panels Anchor, then grab the frame with the mouse is already possible, but the trajectory of the frame after this change. The latter leads to the door frame at the edge of the screen in motion.

How to select a frame, which is currently in focus when several centers framework be at each other?

Thank you!
Sorry for my English!

Hi Kolobokk11

and welcome to the forums, apologies for the slow response to your question.

If I am reading the question correctly you are having problems selecting the correct "cross-hair" when trying to set pan & zoom, mainly because thay stack on top of each other.

select one of the keyframes
click one of the anchor points shown lower left as nine (9) coloured squares.
This will move the keyframe away from the centre allowing you to select it on screen.

---------------------
a little extra info.....
You can also copy and paste the keyframe details to other keyframes.
Right click the keyframe showing as a red diamond and right click.

Thanks for the tip, Trevor! That's something which has always bugged me.

No offense, but that is only half the solution Trevor.
You explained how to easily get an anchorpoint out of the way, but how about getting that same anchorpoint exactly back at its spot once it's been moved?
See, that's the big problem really. Anybody can move anchorpoints to a default location, but moving them back to exactly where they came from, thát's the big issue.
Bottom line: VS doesn't have the right tools to handle detailed work like that. Unfortunately.

lata, thanks for the reply!
I have the following problem. If I want to make a direct panorama, the virtual camera is outside the frame.

GIF animation, click to view

[Kolobokk11]

I can fix that, if adding more anchors. But, when more than a hundred of these anchors, it is impossible to work.

We need to do that when, in the focus on the timeline active anchor does not jump to another position.

P.S. I divided the message into two parts, because your PHPBB incorrectly inserts two GIF in one post.

Hi Kolobokk11

When you first customise the pan and zoom the timeline starts with two key points.

1 / Position the first key point and apply the zoom. this is the start point.
(Your image shows it lower left)

2 / Create another keyframe by double clicking the timeline, position this keyframe.
If you want the same zoom then right click the first keyframe and copy, paste to second keyframe

Now use the anchor points to move this frame away from the first keyframe. (Your image shows it top left)

3 / repeat 2 above. Anchor top right.

4 / if you wish to finish at the start point, copy and paste the first keyframe to the last frame.

Kolobokk11, the keyframes will take on a curve path, this may leave the full frame showing the black border, your only option is to either reposition the keyrrames away from the edge, or using another keyframe zoom in further.

Safe Area and Overscan.
When we view video on a TV set some details around the perimeter about/upto10% does not show, this effect is known as OverScan, do a google search.
You should keep the frame details within the safe area, when we create a Title or work on the Overlay tracks the rectangle you see represents the safe area.
Keep this in mind when setting Pan and Zoom

No offence taken, but I think I did answer Kolobokk11 question in full.

The pan and zoom panel does not have X and Y locations, maybe that would help.
But using the Copy and Paste options works very well, and is quick to apply.

Start your pan and zoom from the left, once you have set the first keyframe then it does not need to be moved again, you select the second keyframe from the timeline, then an anchor point will move that keyframe for you to position on screen. No need to change the first.

Thanks for the response and support!
I think the problem was in my poor knowledge of English.

I take my technical 1080p video and convert it to 720p with simulated camera movements.
So I recorded a demo, which shows that you can not change the position of the anchor if the position of the two anchors coincided.
Focus jumps to the selected anchor to the previous anchor. But this is the simplest case. In real video can be much more anchors.

Hi Kolobokk11

I do not understand why you require so many keyframes, I guess the track will be in a figure of 8.

After selecting the Keyframe, change the zoom from 200% to 300%
Use the anchor points to move the "cross-hair"
Reset the zoom to 200%

[Kolobokk11]

I do not understand why you require so many keyframes...

I wrote above that I take my technical 1080p video and convert it to 720p with simulated camera movements.
Sometimes I have so many anchors, even more than a hundred. This is due to the need of correction, when the virtual camera moves along the edge of the frame, and when it goes beyond the frame. Thus there is a need to add a lot of anchors, as I showed in the picture above.

...figure of 8.

I did not understand what it is.

After selecting the Keyframe, change the zoom from 200% to 300%

It is good only in the simplest cases, when the anchors are not very many. When the field is filled with all the anchors, it is extremely uncomfortable. Once the anchor is moved, it is difficult to get it back into place.

It would be much easier if it were possible to move the active anchor powerfully mouse and do not use other techniques. I think everyone is interested, the product is even better.

[Bushdoctor]

Once the anchor is moved, it is difficult to get it back into place.

I'm afraid it can not be solved and you are right, VirtualStudio simply needs better controls for the anchor points.
It would make much more sense if users can only move one anchor point at a time: once it has been selected in the effect's time line.
Anchor points that are not selected should be anchored in place and not be able to move. Voila, problem solved Corel.

I too use a lot of anchor points sometimes and in order to get that effect just the way I want it, I have to make a lot of small corrections.
The only way I am able to prevent moving the wrong anchor point is by paying very close attention to the time line so I can see which one I actually selected before I move it.
Sometimes Trevor's suggestion is the only solution and you will have to temporarily move anchor points.

Good luck on your project Kolobokk11!

Hi Guys

Sorry for the delay in replying
I have a problem in understanding exactly what you are trying to achieve.


I recognise the problem of selecting the keyframes, but that does not answer why you are using so many. Are adding keypoints simply to straighten the path'

If the problem is simply that the Pan path takes on a curved route then there may be a workround.

Try this :-
Cut the video into two at approx 33%
Using the first clip apply pan and zoom from lower left to upper left
Using the second clip pan and zoom from upper left to upper right.

See attached Smart Package.

[Kolobokk11]

Do not take offense at me! Continue discussion on a serious note tiring.

…but that does not answer why you are using so many.

Maybe you position Corel Video Studio as a product for housewives. But why pay more if for most tasks can be used this editor?

Using the first clip apply pan and zoom from lower left to upper left…

Repeat this procedure 100 times ...

This is normal. Most software developers do not make concessions to users.

In attachment is the static image that shows the ten seconds. That it should illustrate?
