Can you save a scene (performance) without a background? I'm going through Media Encoder CC2018.
In Character Animator, whether I select no background, or white background, the rendered .mp4 video always has a black background......
The mp4 does not support a transparent background. You need to export to a format with an alpha channel, such as mov. Or you can drag the scene from Character Animator to After Effects or Premiere Pro, and the background will remain transparent.
Or you can export from CH as a png sequence.
I use “QuickTime/GoPro cineform RGB with alpha” in media encoder to keep transparencies. No problems yet. I find my personal workflow is quicker this way.
But if you want to scale etc in AE I think the dynamic linking gives better results. So I do that for more complex scenes mixing CH and video and trying to get scaling and clipping right
i stopped using export of png sequences as above two good enough and fewer files to manage.
