Spout2

Spout2 is a simple way to share video between programs on your computer. It sends video directly from one app to another, which is especially useful for streaming things like VTuber avatars or visual effects.

The best part about Spout2 is that it preserves transparency perfectly. VTuber avatars with transparent backgrounds stay transparent in Meld Studio. Window capture requires chroma key to remove backgrounds, which can be tricky and doesn't always look good. Spout2 makes it much easier. Transparent avatars work without additional setup.
