alpha channel batching
on Feb 1, 2015 at 1:55:01 pm

Is there a way to batch Animation files with an alpha channel?
I have a to of lower third seminar points to produce.
Does media encoder have a way to support alpha channels.
I can batch my full page with backgrounds no problem, but I don't see a codec that supports alpha channels.

The Animation codec has an alpha channel. Make sure you set it to output RGB+Alpha in the Output Module settings. You can save that as a preset and export as many lower thirds as you would like. :)

I have been using the method you sent in the screen capture, only exporting one at a time.
Each time I have to reset the RGB + Alpha. Sometimes I forget. I've had over a hundred of these to do.
How do I save it as a preset? I don't see any options here.
Can this preset be used in Media encoder with the Alpha channel?

Thanks

Click the small arrow next to where you select the format in the Render Queue and go to the bottom where it says "Make template". You can name it whatever you like. This preset will be saved and will also be available in Media Encoder.

Ok I made a new template and I can access in AE, but it doesn't show up in media encoder.
I saved all to my documents, then tried to import in media encoder, but it was greyed out.
How do I make it available to media encoder?

Thanks

I just tried it and it seems the presets only appear in AME when you make them in Premiere. No matter, you can make a preset right from within AME. Click the + button that is in the Preset browser, then set it to Quicktime Animation. To add an Alpha channel, set the Depth option to 32 bit. That should do the trick.
