To import an image sequence, in the Studio tap on Import and on Sequence.
Select the folder containing your image sequence and tap on Open.
Then the import windows lets you select the images you wish to import. All the images contained in the folder are selected by default.
You can import several folders at once, which will create a shot with a layer per folder.
To do so, select the parent folder of the group of folders you wish to import.
An image sequence can be imported directly from the shot.
Tap on then Open Layers to open the layers panel, and tap on and choose Sequence.
