FFmpeg is the best option for merging images into a video.

Steps:

  1. Install FFmpeg from ffmpeg.org.
  2. Ensure all frames are named in a sequential format (e.g., frame_0001.jpg, frame_0002.jpg, etc.).
  3. Run the FFmpeg command from C#.

C# Code Using FFmpeg

using System;
using System.Diagnostics;
class Program
{
    static void Main()
    {
        string framesFolder = "Frames";  // Folder containing extracted frames
        string outputVideo = "output.mp4"; // Output video file
        string frameRate = "30";  // Adjust frame rate as needed
        
        string ffmpegCmd = $"-framerate {frameRate} -i \"{framesFolder}/frame_%04d.jpg\" -c:v libx264 -pifmt yuv420p \"{outputVideo}\"";

        ProcessStartInfo processInfo = new ProcessStartInfo
        {
            FileName = "ffmpeg",
            Arguments = ffmpegCmd,
            RedirectStandardOutput = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };

        Process process = new Process { StartInfo = processInfo };
        process.Start();
        process.WaitForExit();

        Console.WriteLine("Video created successfully.");
    }
}

How It Works?

  • -framerate 30: Sets video frame rate to 30 FPS.
  • -i "Frames/frame_%04d.jpg": Reads images in sequence (frame_0001.jpg, frame_0002.jpg).
  • -c:v libx264 -pifmt yuv420p: Encodes using H.264 codec.
  • Creates output.mp4.

Pros:

  1. Very fast
  2. High-quality video output
  3. Supports multiple formats (MP4, AVI, etc.)
