"size and position" vs preview "video mode"

[ndq0345934]

i always set preview to either “auto” or a low-res so i can work efficiently.

I often use “size and position” filter, then realize that exporting at a high-res will have those size and positions way off from expected location.

Can we have percentile size and position rather than static?

There is an explanation here:

Logo does not show up when exporting with other resolution

This used to work in older versions of Shotcut because size and position info was saved used percentages, which would scale when you changed the resolution at export time (but it never worked for HTML-based filters because HTML is not such a simple thing to go into programmatically and adjust everything). Since the introduction of keyframes, Shotcut needed to start using some different APIs that is now saving the information using pixel values. I am aware of this and am working on a fix to save …

Can we have percentile size and position rather than static?

Recent versions avoid the problem in the linked post by internally rendering at the project/composition resolution and then scaling to the export resolution. This makes a more universal solution including HTML-based effects, which may be used more in the future. In that case, having size and position information stored as percentile will not help. I think we need to come up with a separate solution for working in a lower-res draft/preview mode.
