[FFmpeg-user] Fast Conversion with compressed size and maintain Quality

[AMIT KUMAR]

Hi,

 I have a Mp4 file whose size is 235 MB but i need to compress and
    Maintain quality  and convert without taking too much time.

    But when i use this command to create that all thing they are taking 4
    to 5 min time and quality is very low whereas the size is compressed (It
    becomes 32 Mb).

    So, can any one help me to perform this operation.

   1).  "-i 503148_inn.mp4 -codec:a copy -vcodec libx264 -crf 24 503148.mp4"

   2).  "-i 503148_inn.mp4 -codec:a copy -preset ultrafast -vcodec h264 -b:v
       1000k -acodec mp3 503148.mp4"

 whereas i am sending the file URL where you all are download and test the
 file.
 Please help me its very very urgent for me.Thanks in advance.
