Delivery suggestions
- Use thin mattes for narrative projects where titles sit inside the frame.
- Use Film Border mode for vintage edits, creator packs, and social overlays.
- Use custom sizes when a platform, LED wall, or client deck needs exact dimensions.
FAQ
- Will the PNG work in mobile editing apps?
- Yes. Exported files are lightweight and keep their transparency, so they drop onto CapCut, VN, and InShot timelines with no extra blending steps.
- Can I customize sizes?
- Yes. Use the width and height fields to generate custom transparent PNG frames for non-standard ratios and exact client specs.
