It definitely works so thank you very much for the solution. Unfortunately i don't really understand what you did.


If you have the time, could you explain what the [p] is going on there?

Thanks in advance.

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.
