You've finally finished that killer transition. The easing is perfect. The motion blur looks professional. But when you go to export your asset for a collab or a different project, you're met with a solid, boring black void where your transparency should be. It's frustrating. Honestly, dealing with alight motion png transparent files is one of those things that seems like it should be a one-click fix, but the app has some quirks you need to navigate if you don't want to lose your mind.
Most mobile editors treat transparency like an afterthought. Alight Motion is actually pretty powerful here, but if you don't hit the right toggle in the export settings, the app defaults to filling in the "empty" space with black pixels. That's just how video encoding works by default. If you want that clean, cut-out look for your overlays or logos, you have to speak the app's specific language.
Why Your "Transparent" Exports Still Have Backgrounds
It’s usually a settings issue. When you start a new project in Alight Motion, the "Background" color you choose in the project setup—be it Black, White, or Light Gray—isn't just a workspace preference. It's a placeholder. If you want a true alight motion png transparent result, you have to select "Transparent" (the checkerboard pattern) right at the start.
If you've already started the project, don't panic. You can change this by tapping the gear icon. But even with a transparent background in the workspace, the export format is what actually kills the transparency. Most people try to export as a "Video" (MP4). Standard MP4 files do not support alpha channels. Period. They will always flatten your work onto a solid color.
To keep things see-through, you’re looking at two main options: "Current Frame as PNG" for static images or "XML/Project Package" for sharing the actual editable layers. If you're trying to make an animated sticker or a transparent video overlay, you're moving into the territory of "Image Sequence" or "GIF," though GIF transparency in Alight Motion can be hit-or-miss with edge fringing.
The Secret to Clean Alpha Channels
Let's talk about the "Current Frame as PNG" option. It's the most common way people use alight motion png transparent assets. Maybe you created a custom text glow or a specific shape that you want to use as a watermark in another app like CapCut or Premiere Pro.
- Make sure your project background is set to "Transparent." You’ll see the grey and white squares.
- Move your playhead to the exact frame you want to save.
- Hit the export icon (the square with an arrow).
- Choose "Current Frame as PNG."
- Check the preview. If it looks right, save it to your gallery.
What if you want the whole animation to be transparent? That’s where things get tricky. Alight Motion allows for "PNG Sequence" exports. This creates a folder full of individual transparent images. It's a professional workflow, but it's a nightmare for casual phone users because you then have to re-assemble those frames elsewhere. Most mobile users are better off using the "Luma Key" or "Chroma Key" effects later on if they absolutely must export as a video, but that's a "fake" transparency that often leaves weird outlines around your subject.

Avoiding the "Black Outline" Ghosting
Have you ever noticed a weird, thin black line around your transparent PNGs? This is called "pre-multiplication." Basically, the app calculates the colors based on a black background before it cuts them out.
To avoid this, try to keep your edge feathers minimal. If you're using a "Glow" effect, the transparency might look "dirty" when you import it into another app. Professional motion designers often use a "Solid Matte" and then mask it, but on a phone, the easiest fix is usually just ensuring your project settings were transparent from the very first second you hit "Create Project."
Importing PNGs vs. Creating Them
Sometimes the problem isn't exporting; it's importing. If you bring a "transparent" PNG into Alight Motion and it has a white background, the file you downloaded probably wasn't a real PNG. We've all been there—Google Images lies to us with those fake checkerboard backgrounds that are actually part of the image.
Always check the file extension. If it ends in .jpg or .jpeg, it's physically impossible for it to be transparent. It has to be .png or .webp. When you bring a real alight motion png transparent file into the timeline, Alight Motion should recognize it instantly. If it doesn't, go into "Effects," add "Chroma Key," and pick the color you want to vanish. It's a band-aid solution, but it works in a pinch.
Advanced Transparency: Using Masks
If you're doing complex masking, transparency becomes a layer-based game. You can use a "Mask Group" to define what is visible and what isn't. This is basically manual transparency. You put a shape over your video, select both, and hit the mask icon at the top.
This creates a "hole" in your project. If you have nothing beneath that masked group, it effectively becomes transparent. This is how high-end editors create those "video inside text" effects. When you export this using the PNG sequence method mentioned earlier, the "hole" remains transparent.
Practical Steps to Master Transparency
If you're serious about using Alight Motion for professional-grade overlays, stop relying on the default export button.
- Audit your project settings: Go back to the home screen, long-press your project, and check the background color. If it's not the checkerboard, change it now.
- Test your exports: Export one frame as a PNG and open it in your phone's default gallery. If the background is solid white or black, your transparency failed. If it looks like it has no background (or a neutral one depending on your phone's UI), you're golden.
- Use High-Quality Assets: Don't start with a low-res JPG and try to make it a transparent PNG. You'll get "crunchy" edges that look amateur. Always start with high-resolution vector shapes (available inside Alight Motion) or high-quality PNG imports.
- Check for "Blending Mode" conflicts: Sometimes, if you have a layer set to "Screen" or "Multiply," it won't export with transparency the way you expect because those modes require a background to interact with. Switch back to "Normal" blending if you're exporting a standalone transparent asset.
Transparency isn't just about what's not there; it's about making sure the edges of what is there stay crisp. If you're seeing jagged pixels, increase your project resolution to 1080p or 4K before you export that PNG frame. It makes a world of difference when you scale that asset up later in a different edit.
Stop settling for those annoying black boxes around your logos. Set your project to transparent, use the "Current Frame as PNG" export, and verify your file types before you start the heavy editing. Your future self—the one who doesn't have to spend three hours masking out a "transparent" logo—will thank you.
