By default Premiere Composer only shows a static image for each MOGRT in the User Library. However, you can render your own video previews like this:
- Render a preview for your mogrt as ".mp4" or ".webm" format (H264 or Vorbis).
- Move the preview file next to your .mogrt file
- Rename the preview file like so:
- Let's suppose your mogrt is called Example Graphics.mogrt
- Call the preview file Example Graphics.mogrt.mhpreview.mp4
Here is an example with MOGRT called "Book"
