Need to hold last frame of gif after looping twice - export from .mov file
Overview:
I am creating some animated ads in After Effects (from templates provided by my client), then exporting them to .mov files
After this, I open them in Photoshop in order to export them as gifs.
After the gif plays twice, I would like to have the last "frame" stay there (client logo, CTA button, etc.) but those disappear, leaving just a black rectangle (the background color of the ads).
Can someone help please? Thank you!
