Lossless MKV to MP4
Hello everybody!
I need a (simple) method to transform a mkv container format (video, audio tracks, subtitles, ecc) into a mp4 container format without loss of quality and eventually without become crazy. Last edited by gigirex; 15th May 2011 at 12:15. |

Get crazy!!
Thanks, Brazil2, but this is exactly what I means when I say "get crazy!":

Simple, you can't put DTS in mp4
> [mp4 @ 03fa5260] track 1: could not find tag, codec not currently supported in container

Hi gigirex, I once have the same requirements as you and I call some customer service center for help, and most of them tell me that any conversion need to recode, so the quality loss is unavoidable anyway, you should also remember that if the output bit rate is smaller than your input bit rate, the quality would be bad. So a suitable bit rate is a must while converting. And I used ojosoft MKV to MP4 converter to settle my problem at last. You can freely set your bit rate, frame size and frequency range by an edit button. Maybe it is suitable for you, too. http://www.ojosoft.com/how-to-conver...converter.html
