How would I create a Transparent Background for a video?

Right now I have a really simple particle setup which I'm trying to export as just that, without any solid backgrounds, is there a workaround?

@Melanie Stirner well I'm asking specifically how to fix that ap4h encoding, ultimately I wish to see the video rendered as a png, on top of another png (image), it sounds rugged but I just wanted to get a rough sketch for a banner I'm working on


Hi @LEFT4LAZY 

Ok, so I got you wrong. I just had a look at you screenshots and the text. Your output settings for the export are right, Prores 4444 works with Alpha. I think that aph4 is just the same, but in Windows language. Looks like you can't preview it in Media Player because the format is not supported. Since .mov is an Apple format (and the codec as well), there are often issues with Windows. If you try to open it in Quicktime Player the preview should work.
 It should still be working when you import the file into After Effects or Premiere Pro. So, if you want the video to be above another video (or image), that's just the way to go.
Is that what you wanted to achieve?

If you turn on Transparency Grid and see through the black, all you have to do is add the composition to the Render Queue and choose the High Quality with Alpha Output Module template from the dropdown list. 

 

It would help us help you if you told us how you generated the particles. I see that effects are added to the Adjustment layer and Layer 2, and it looks like CC Particle world is applied to Layer 3. CC Particle World generates a transparent background, so You might be all set.

Hey @Rick Gerard so if I am not mistaken, I've done as you've said in the provided photos, yet once I render the video it exports into 'encoded ap4h' which I tried to convert to .mp4 (was .mov) through a third party app, yet the issue presists, what might I be doing wrong in these steps?

Hi @LEFT4LAZY 🙂

.mp4 does not support alpha, so you will have a solid background again as soon as you convert your .mov to .mp4

The settings you chose are right and the rendered .mov should be with transparent background in the end. Still, the file will probably be quite big (even bigger when you use animation codec). You could also work with .png or .psd sequences with alpha. It could be that they won't be that big, give it a try. It depends on what you would like to achieve with the transparent bg of the video.
