Also keep these considerations in mind when creating images for use in video:
•
Video-editing applications, such as Adobe Premiere, do not support 16-bits-per-channel images.
•
Some video-editing applications can import an individual layer from a multilayer Photoshop (PSD) file.
•
If your Photoshop image file has transparency, some video applications, such as Adobe Premiere, preserve it.
•
If your file uses a layer mask or multiple layers, you might not have to flatten the layers, but you might want to
include a flattened copy of the PSD file in the PSD format to maximize backward compatibility. In this way, you
will be able to import your Photoshop file successfully into video-editing applications such as Adobe Premiere.
