@melory-f Hi, I made a long post about how the Track motion settings relate to Media/Project, size, aspect ratio etc.. but to be honest after a couple of hrs trying to work it all out the sizes in Track Motion didn't seem to corelate to anything. I'm quite happy to be schooled on this.

Basically I added a 1920x1080 clip to a 1080x1920 project, increased it size with Track Motion, I had to increase the height to 6069 to fill the preview project size/height. (I tried working out why that number but couldn't)

Half of 6069 = 3034.5

So if you set the project to 1080x1920 as you have done, leave Pan/Crop to the default 1920x1080, & set Track Motion height to 3034.5 you'll get the desired effect. (+ or - 480), save this as a two Presets, one for +480 the other for -480..

1080x1920

This picture is on 2160x3840, the same Track Motion presets I created work but the height auto changes to 6069.

@Gid 1920 * (16 / 9)² = 6068.148

@melory-f However, I don't recommend scaling the footages too much in Track Motion. The scaling of Track Motion is based on project size, so it may cause the footages to become blurred. In this case, it's better to use Event Pan/Crop, which is based on the resolutions of the footages themselves.

@zzzzzz9125 Ah thanks 👍 I got to the 16÷9 to get 1.7777777777778 but didn't sq it, that's the step I was missing. I guess I was only working on one axis. (if that's the correct term, I can see it in my head 🙃😁) 👍

@melory-f

Probably, the most direct way to achieve your goal is to recognize that you are trying to vertically stack parts of two 1920x1080 images into a 1080x1920 frame. The symmetrical dimensions available for each vertical half is 1080x960 (aspect ratio 1.125). 

• Using Event Pan/Crop, untick the Lock Aspect Ratio lozenge.
• Type 1080 into the Width field on the Pan/Crop panel.
• Type 960 into the Height field on the Pan/Crop panel
• Tick the Lock Aspect Ratio lozenge.
• Resize the crop box to include your desired subject.
• Repeat Pan/Crop operation for both tracks.

On the Track Motion panel, locate the top and bottom view to fill the screen.

Have you changed any Pan/Crop settings?

Post a screen shot of the Pan/Crop panel.

No, I haven't changed any Pan/Crop settings

@melory-f said: "I haven't changed any Pan/Crop settings"

That's why you're getting unexpected results with Track Motion. Follow my previous post.

For best results, use Pan/Crop to set the size and shape of the event(s). Use Track Motion to locate the event(s) on the canvas.

that's the feeling track motion arose in me as well!

anyway, thanks for your input and time trying to figure that out 🙏

I'm sorry, but I don't understand this...absolutely, could you please explain about scaling of track motion and pan/crop? How they differ and how they work?

Thank you! I tried this and that worked for me! However, I still have a feeling that I don't fully understand how it works.

When the dimensions are symmetrical - all is fine, but I think when there will be deffirernt sizes and dimensions, that when the difficult times begin...

@melory-f Hi, sorry I can't explain it, I 98% understand it but can't put it into words, in my calcs I was doing 6÷9 to get 1.7777777777778 but I didn't sq it, so I was still working in 1 dimension, squaring it puts it into 2 dimensions, (1 dimension is a simple line, 2 dimensions is a sq) Like I say I can't explain it 😵😂🤦‍♂️ Your quote tagged me (in blue) but maybe @zzzzzz9125 or @john_dennis can explain better.

Googling it just adds confusion to my thoughts 😂

Squaring a number doesn't "put it into 2 dimensions" in a geometric sense. Squaring a number is a mathematical operation that multiplies a number by itself, resulting in a new numerical value. It doesn't change the dimensionality of the number itself. The term "squaring" is also used in geometry to describe the area of a square, which is a two-dimensional shape, but this is different from the mathematical operation of squaring a number. 

I'm sorry, but I don't understand this...

@melory-f @Gid This is a very simple math problem. Just think about their actual width and height, as well as the target width and height.

If you directly import a 16:9 footage into a 9:16 project, it will look like this:

It's not 1920 * 1080, but 1080 * 607.5.

Scale it by 16/9 times:

Scale it again by 16/9 times:

Therefore, we need to scale it by a total of (16/9)² times.

absolutely, could you please explain about scaling of track motion and pan/crop? How they differ and how they work?

You can check out my explanation in another post: https://www.vegascreativesoftware.info/us/forum/nearest-neighbor-video-interpolation--148895/#ca936539

When you scale it only using Track Motion as above, the original size you are scaling is only 1080 * 607.5. On this basis, you also have to scale it by (16/9)² times, which of course will make the footages blurry.

From my point of view, avoid using Track Motion to enlarge the footages. (Decreasing is acceptable.) In most cases, Pan/Crop should be used for enlarging.
