@Kailash Sahu , you could try the following code to drag files to listbox and convert it to the mp4 files.

Code:

public partial class Form1 : Form  
    {  
        public Form1()  
        {  
            InitializeComponent();  
            listBox1.AllowDrop=true;  
        }  
  
        private void button1_Click(object sender, EventArgs e)  
        {  
            string[] clist = listBox1.Items.OfType<string>().ToArray();  
            FFMpegConverter converter = new FFMpegConverter();  
            foreach (var item in clist)  
            {  
                converter.ConvertMedia(item, Path.Combine("D:\\",Path.GetFileNameWithoutExtension(item)+".gif"), NReco.VideoConverter.Format.gif);  
            }  
        }  
  
        private void listBox1_DragEnter(object sender, DragEventArgs e)  
        {  
            if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.Copy;  
        }  
  
        private void listBox1_DragDrop(object sender, DragEventArgs e)  
        {  
            string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);  
            foreach (string file in files)  
                listBox1.Items.Add(file);  
        }  
    }  

Based on my test, it can convert gif to mp4 successfully at the same time.
