Why Your Moho Animations Have White Edges After Importing into After Effects


Are your outlines looking blurred, washed out, or surrounded by a strange milky glow?


In this short video, I’ll show you exactly why this happens — and how to fix it in just a few seconds, even if you’re not an After Effects expert.


You export your animation from Moho Pro as a .mov file with transparency, import it into After Effects, and suddenly you see bright halos around your characters or graphics?

This is one of the most common issues when exporting from Moho — but luckily, it’s also one of the easiest to fix.

In this episode, you’ll learn:

  • The difference between Straight Alpha and Premultiplied Alpha,

  • Why Moho exports using Premultiplied Alpha by default,

  • How to correctly interpret the alpha channel in After Effects so the white edges disappear.

You’ll also see a simple two-circle RGBA demo that clearly shows what’s really happening in the pixels - so you’ll finally understand where those “milky” borders come from.

Watch the video to the end and fix your renders once and for all!

After this tutorial, your characters and graphics will look clean, sharp, and professional — with no artifacts, no glowing outlines, and no frustration.

In a world overflowing with visuals, your product has only seconds to make an impression. You want people not just to see it — but to feel its story, its quality, and the idea behind it. The challenge? Static images rarely do justice to the experience you’ve built. They can show what your product looks like, but not what it feels like.  That’s where motion design in 3D changes everything.  Imagine this:  A small plastic jar slowly rotates in the light. The cap twists open, and three tablets pop up playfully — as if inviting the viewer to explore. After a brief moment, they gently drop back inside, the lid closes with a smooth click, and the jar completes its turn, revealing a clean label with your logo.  It’s just a few seconds of motion — yet it tells a complete story of innovation, precision, and trust.  This is the power of motion design:  • It turns a simple product shot into an immersive visual story.   • It helps your a...

Behind the Visual Design of the 40th World Youth Day of the Diocese of Kielce

For this year’s 40th World Youth Day of the Diocese of Kielce, held on November 22, 2025 at the Congress Center - Targi Kielce, I had the opportunity to create the background visuals and the intro animation displayed on stage during the event. The starting point for the intro was the official promotional poster designed by Jakub Radek. Using elements from the poster, I developed animated sequences that matched the event’s visual identity and worked well with the stage lighting and overall atmosphere. Seeing the visuals presented live—together with the music, lighting, and the energy of the audience—was a meaningful moment. It’s always satisfying to watch a digital project become part of a real, shared space. I’m grateful for the chance to contribute to the visual side of this celebration.
