I need 1080p mp4 output quality from adobe spark for the videos im making. I have a free account currently. Will i get better resolution mp4 if i get a paid adobe account ?? I further need to edit these videos in iMovie and want to publish these videos on youtube at 1080p streaming quality. Spark does not provide 1080p currently.

Oh, and also if Adobe plans to discontinue Spark then please do launch a replacement app pronto which does everything that spark does.
