Issue transcode MPEG2 to DNxHD120

by

I use the software Kdenlive in Archlinux OS to transcode a 1 hour of video (1:12 :10) in Mpeg2 format in 1440x1080px 50i to DNxHD120 1920×1080 25p. Kdenlive print those parameters in the transcode’s window : -s 1920x1080 -r 25 -vb 120000k -threads 0 -vcodec dnxhd -acodec pcm_s16le -ar 48000 %1.mov.
The problem is : the final video is more shorter (00:53:35) and the video and audio is not synchronized. Do you know how resolve this issue?

Thank a lot 🙂
