How to merge all frame images in video file in C#?

Question

Ravi Vishwakarma · Answer

FFmpeg is the best option for merging images into a video.
Steps:
Install FFmpeg from ffmpeg.org.Ensure all frames are named in a sequential format (e.g., frame_0001.jpg,
frame_0002.jpg, etc.).Run the FFmpeg command from C#.
and 
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.");
    }
}
and 
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:
Very fastHigh-quality video outputSupports multiple formats (MP4, AVI, etc.)
