You use the videos, GIFs, and PSDs that you created in the other apps as the background layer of your sequence.
First, please save your videos, GIFs, or PSDs created in other apps to the iOS Files. Select “Open Files” when creating a new Sequence. Switch to the “Browse” tab. Select the app folder, and import the files that you are looking for.
For example, you might want to import a PSD file from Procreate. Select “Open Files” while creating a new sequence.
Tab “Browse” and find Procreate’s folder.
Select the file that you wish to import to the sequence.
