Trying to reuse package for "video cropping" as well

[ColorsCL]

Hi! I've been using the library lately and it's awesome but I wanted to also use it for cropping videos (on the server-side),
I tried loading a transparent image in base64 so I can still use the resizer with the video playing on the back but I encounter some issues...

Has anyone tried to do something like this with this package? Any ideas?

Thanks!
