[INFO] [Feature request] Keep height ?

[Selur]

I understand that Hybrid will modify the width only when the input PAR is not 1x1 : is it the case ?

yes.

this sets Crop/Resize > Base > Picture resize > resize method = "10 - bicubic spline"

No it shouldn't change the resizer, '10 - bicubic spline' is just the default.

this enables Crop/Resize > Base > Picture resize > "Auto adjust" --> I chose "width" (I understand the width will adjust to the height with output PAR = 1x1)

yes.

then the "target resolution" is set to a certain value in Hybrid --> is it a value specific for the 1st video to be encoded, or for all the videos ?

that resolution is based on the currently selected video unless 'adjust keep resize for source' (or 'keep resize for new source' for multi file input) is enabled.

Crop/Resize > Misc > On source change > auto crop : enabled

makes only sense in case your sources have black borders to crop

do you agree ?

yes, looks okay.
