Add alpha to video material and image transparency

I would like to have the possibility to add alpha to video material in some cases it is interesting to put transparency in the videos.

and image sequence to be able to add video as a sequence and not in video format.

Thanks for the suggestion :seedling:, adding alpha to video material template is already in our development plan.
:face_in_clouds:Sorry I don’t quite understand the second suggestion you mentioned, could you please explain the scenario?

that the input format can be a sequence of images instead of an .mpe4/.avi…
