How to extend clip pixels on canvas?

Post by Ra4bo »

Hey, if I move a clip with Transform Position X or Y and I don't scale the clip to fit, there will be an empty area on the canvas. Adding another layer will reveal an ugly dividing line at the border of the transformed video.

Is there any function or effect to extend the bounds of a clip, i.e. if the video has a black border, filling the empty space with that color?

Thanks guys.

A solid color effect after transform with show image enabled and color set to black should do what you'd like.

Here is a short video showing another approach using blur and vignette.

To disable alpha I usually throw a cheap effect like Flip: disable the flip checkmark and enable black bg. This comes in handy also if you dont want alpha for the entire composition so you can stack slices in the advanced output

That's the pre-post mult-demult filter we lack of.
Dealing with this from 4, I use to believe solid color has lower impact on pipeline.

I was wondering when you’d show up, Francoe. For real though, I’m honestly curious what you think a multiply filter would bring to the table that solid color with show image enabled doesn’t already do.

Oh Joris, sorry, I'm not expecting a different behaviour or result.
Is just my kind of work use that process all the time. So I was using solid, flip, sometimes an inverted crop, even the reveal fx. I can do all the job with the bundled filters. But allways have the suspect that I'm doing something wrong because the use of filters that are not especifically designed for that (you know, I come from the node based school, stacking simple tasks).
I use to ask myself: is there an overprocess if I use that filter for an solid composite? Is certain filter adding weight to the pipeline if I use it for an alpha switch? etc..
Maybe I'm getting the best I can get, but the lack of an specific filter makes me doubt. :lol:
