Photoshop transparency to alpha channel

[Ronaldo Montalvo]

maybe try the action under video actions called “alpha channel from visible layer”. this might work for what you need, but you need to turn off any layers you don’t want alpha for. you could also create a new action and assign an open F-key command. start recording, command click the layer menu with the artwork you need the alpha for, then select “save selection as channel” and stop recording. when you hit the F-key it should create a new alpha channel from whatever layer you have selected instead of the just the visible layer.

I wrote the action.. it works well. You can also combine it with the Image Processor Script to batch process a folder of iamges.

OK
I’m missing something. I looked in my Actions folder and there is no “alpha channel from visible layer”.
Where do I find Video Actions?

i don’t think you’ll see an individual action file for that. it’s part of the file in the pshop actions folder called “Video Actions.atn”. look at the ACTIONS menu under WINDOW in pshop. you should see the “alpha from visible layer command” under the list of actions in the video actions menu. if for some reason you don’t have it you can always create and record your own video actions.

I had the same problem, no actions appeared in my action panel except default. Click on the twirl down menu for actions and go to Load Actions. Then find your PS folder and go to Photoshop/Presets/Actions. All of my missing actions were stored in that folder. Just open them up and you are ready to go!

When I went to “Load Actions” in the twirl down menu, the actions folder appeared empty. But Explorer showed the six stock .atn files in the folder. I found I could drag the desired file from Explorer to the “Load Actions” window, and the actions would load.

Thanks everybody. This is a big help. It’s always fun to find hidden goodies that make your life easier.
