Saving Video on Mobile – Hide or Show Video while saving it?

Quick and short question.

I'm building iOS Video Editor app. Within the Video Edit Screen I'm placing a "Save button" so the user can press Save quickly.

Do you think:

1) I should place the "saving" pop up in the middle of the screen, hiding the video and focusing on the saving process

2) Or should I place it below the video, on-top of the edit tools, and keep the video visible?

Would love to hear your thoughts. Roi
