Try this
> -vf "[in]pad=1920:1080:240:0[p];movie=logo.png[watermark];[p][watermark]overlay=10:10[out]"
Any filter needs an input and if you don't specify one, it will take the last used/available.
You cannot reuse an already used input. To work around this, the op split= was introduced, but in my opinion fails to work. I always get grey instead of content on the second output of split.

best wishes,
