        Dim strEachFile As String
        Dim intFile As Integer
        Dim intFrame As Integer
        Dim intFLoop As Integer
        objFProcess = New System.Diagnostics.Process
        objFProcess.StartInfo.FileName = "c:\ffmpeg.exe"
        objFProcess.StartInfo.Arguments = "-r 1 -f image2pipe -i pipe:.bmp -pix_fmt yuv420p -crf 35.0 -vcodec libx264 -an -coder 1 -rc_lookahead 50 -threads 0 D:\test.mp4"

        objFProcess.StartInfo.RedirectStandardInput = True
        objFProcess.StartInfo.RedirectStandardOutput = True
        objFProcess.StartInfo.RedirectStandardError = True
        'objFProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
        'objFProcess.StartInfo.CreateNoWindow = True
        objFProcess.Start()
        objStream = New System.IO.BinaryWriter(objFProcess.StandardInput.BaseStream)
        strFiles = My.Computer.Clipboard.GetText().Split({System.Environment.NewLine}, StringSplitOptions.None)
        intFrame = 0
        intFile = 0
        For Each strEachFile In strFiles
            'MessageBox.Show(strEachFile)
            intFile = intFile + 1
            objBitmap = New System.Drawing.Bitmap(strEachFile)
            For intFLoop = 0 To 24
                intFrame = intFrame + 1
                cmd1.Text = intFile.ToString & "-" & intFrame.ToString
                My.Application.DoEvents()
                objBitmap.Save(objStream.BaseStream, System.Drawing.Imaging.ImageFormat.Bmp) Rem this line give me below (attached) error :(
