Preview scaling "rearranges"

Hi,

AFAIK has PreviewScaling a problem with ‘Mask Simple’ and ‘Rot/Scale’.
In my case I’m using first the mask filter and then the Rot/Scale filter…

None PreviewScaling:

With PreviewScaling:

It doesn’t matter, which scaling…

-------EDIT--------
In addition:
If you use ‘Mask Simple’ e.g. for a video clip and you have set width and height and you then add ‘Rot/Scale’ then the width of ‘Mask Simple’ is “broken”.

I tried to reproduce, but I have not been able to figure out the combination to cause the problem you see. Please post a screenshot that shows the filters panel to see all filters and in which order. Also, include the timeline if you are using Mask: Simple Shape for compositing tracks instead of using Mask: Apply.

First ‘Mask Simple’ and ‘Rot/Scale’:

I have only activated the ‘Rot/Scale’ filter:

----------EDIT-------------
I just tried with (all) PreviewScaling:
PreviewScaling (in that case) is ok.

And now the issue with PreviewScaling:

It shows the ‘Mask Simple’ placement (yes, it’s not pretty ):

This shows, how it looks with all filter activated and without PreviewScaling:

This shows with PreviewSclaing (doesn’t matter which scaling):

--------------EDIT-------------------
The issue is, when I move the source (in the Timeline) (with ‘Mask Simple’ and ‘Rot/Scale’ filter) by ‘Rot/Scale’ filter (e.g. x axes), then PreviewScaling “rearranges”…

[Earlybite]

And (hopefully) the final:

Source not moved by ‘Rot/Scale’ and without PreviewScaling:

Source not moved by ‘Rot/Scale’ and with PreviewScaling:

Source moved by ‘Rot/Scale’ and without PreviewScaling:

Source moved by ‘Rot/Scale’ and with PreviewScaling:

Ok, I hope this is it…

--------------EDIT------------------

But I’ve found some more :

In this case x axes is ok, but the with of ‘Mask Simple’ has changed…

Without PreviewSclaing:

You raised two issues. For the below:

@Earlybite

If you use ‘Mask Simple’ e.g. for a video clip and you have set width and height and you then add ‘Rot/Scale’ then the width of ‘Mask Simple’ is “broken”.

This happens when the aspect ratio of the clip differs from that of the project. This problem is unrelated to preview scale and has been there forever. I doubt I can fix it.

The second issue I reproduced: the Rotate and Scale X and Y parameters are not scaling correctly under preview scale. I am looking into it.

Thanks for the interest…

I just tried it…, e.g. the image from the previous post (with that door) is original 1920x1277 and I resized it to 1920x1080 and all is fine.
Ok, good to know, now I definitely can use PreviewScaling, what means even more filter…

Thanks!

Hi, again!

Maybe I’m wrong, but it seems, that the ‘Size/Pos’ filter do not have the issue like with the ‘Rot/Scale’ filter…, definitely with the mode ‘Anfüllen’. I can resize the masked part, move…, and everything works fine.
What is the difference to ‘Rot/Scale’?

---------EDIT----------
The following applies to ‘Size/Pos’ in mode ‘Auffüllen’:

‘Mask Simple’ + ‘Rot/Scale’ == Issue // ok
‘Mask Simple’ + ‘Size/Pos’ == No Issue // ok
‘Mask Simple’ + ‘Size/Pos’ + ‘Rot/Scale’ (and e.g. moving x axes) == no Issue // ok

Best regards

The second issue I reproduced: the Rotate and Scale X and Y parameters are not scaling correctly under preview scale.

This is fixed for the next version 20.04
