Automatically Upscale Clips in Upscaled Sequence

[KuleshovEffect]

I have a sequence at 1920x1080.

Some of the clips in this sequence are UHD (3840x2160).

The scale of these clips are at 50% so they fit in the HD sequence.

I want to create at new sequence at 3840x2160 that uses the full resolution of these clips, so their scale should be at 100%.

But if I change the sequence settings to UHD, all of my clips remain at 50% scale (even if "Scale motion effects..." is checked).

I could go through every clip and double the scale, but is there a way to automaticlly rescale clips when the sequence is resized?

Nesting the HD sequence in a UHD sequence isn't an option - nests don't concatenate, and I lose the full UHD resolution.

Select all the clips, right-click and choose "Set to frame size."

Note that any 1080 or smaller clips in the sequence will also get scaled up over 100% in order to fit the UHD frame (which I assume you want?)

Sorry, I oversimplified.

I've repo'd and scaled many clips in the sequence - "Set to frame size" will throw away all of my Motion effects.

But it looks like if I nest the HD sequence in a UHD sequence and select "Scale to frame size", it re-rasterizes everything correctly. So perhaps I finally found the use case for Scale instead of Set.
