We're constantly working on ways to improve the processing times of Artwork. At the moment, processing can vary depending on what files were provided. In particular, the duration of the audio track affects the timing most. If you plan on sharing your video on Instagram afterwards, we suggest trimming it down to Instagram's maximum length of 60 seconds to both lower your file size and speed up processing.
If your video doesn't arrive after 10 minutes, first check your Spam folder. If it isn't there, please try creating your video again. If that still doesn't succeed, please reach out to support and we'll investigate the issue for you.
