please can someone help
i have imported a video clip into photoshop successfully so now i have 200 frames

i wanted to green out the area around the persons head its a headshot and apply it to all 200 frames so it still shows her head talking but greenscreens around the outside of the head

Now i know very little but i know it involved the actions tab recording and then file automate it however heres my problem

When i do this it only automates and processes the first image with green backing rest are all same as original and i get a no feather exists error at end of each frame

HELP!!! Please

Then once this is Done HOW do i Export or save it back into a video clip??

i originally tried exporting from premiere to photoshop as filmstrip (.flm) but it saved as 1 file

i also get a select document that appears in the action window and no idea what to do
