Mif – Image sequence to video / GIF

A small C# WPF app for Windows that makes videos or animated GIFs from a sequence of images, with GIF-style controls.

I'm not a programmer, so this whole thing was vibe-coded using Cursor.

Features

• Frame stack: Add multiple images (PNG, JPG, BMP, GIF, TIFF), reorder with ↑/↓, remove or clear.
• Frame delay: Set delay per frame in 1/100 of a second (e.g. 50 = 0.5 s).
• Export as GIF: Saves an animated GIF using the current frame order and delay.
• Export as video: Saves an MP4 via FFmpeg (same delay = frame duration).

Build and run

dotnet restore
dotnet build
dotnet run

Or run bin\Debug\net8.0-windows\Mif.exe after building.

Video export (FFmpeg)

Video export uses FFmpeg. Either:

1. Install FFmpeg and add it to your PATH, or
2. Place ffmpeg.exe in the same folder as Mif.exe.

Without FFmpeg, video export will show an error; GIF export does not need FFmpeg.

Requirements

• Windows
• .NET 8.0 (or SDK for building)
