PNG Sequence to Transparent Webm converter For Unity

Requires FFMPEG to be installed.
Tested on Unity 6

The PNG to WebM Converter is a Unity plugin that makes it super easy to turn a series of PNG images (like sprite sheets or frame sequences) into a WebM video with transparency. WebM is great for web apps, especially when you need videos with see-through backgrounds. This plugin uses VP8 encoding to keep the alpha (transparency) intact.

Key Features:

• Convert PNG Sequences to WebM: Turn PNG image sequences (like image1.png, image2.png, etc.) into a WebM video while keeping the transparency. Perfect for animated sprites, UI elements, and effects in games or web apps.
• Auto File Name Detection: The plugin automatically figures out your file naming pattern from the first selected PNG image, saving you time.
• Adjustable Frame Rate: Set the frame rate for your WebM video, so you control how fast or slow your animation plays.
• FFmpeg Integration: Uses FFmpeg (a popular video tool) to handle the conversion and keep the alpha transparency in the WebM file.
• Custom File Name: Choose a name for the output WebM file, making it easy to organize your projects.
• Optional FFmpeg Path: If FFmpeg isn’t set up on your system, you can manually point the plugin to its location.
• Easy UI: The user-friendly interface in Unity lets you select your first frame, adjust the frame rate, set the file name, and more—all with just a few clicks.
• Clear Feedback: After converting, the plugin will either show you success with the output folder opening, or an error message to help fix any issues.

Tip: Don’t forget to enable transcoding and the "Keep Alpha" option in the video player to preserve transparency in the final video.
