Im very glad for KDEnlive. It is what I needed. Now I can do what I need. I can correctly export only to "high quality" (dv or avi). I cannot correctly export to MPEG, MPEG4, DVD (I have not done exact tests). Only first clip (my first clip is created from picture) is exported without effects. It is not problem for me, because I can encode high quality by mencoder. I use Debian Etch and packages from debian-multimedia.org I have installed: ffmpeg and DVDauthor. Jirka (GeBu) |

I can confirm this on Debian unstable. Cheers, Carsten |

I did a quick test mixing a low res mpeg with a color clip and dv file, sepia filter and crossfades, all formats exported fine. For your info, exports are all passed to FFMPEG using the parameters found in the file exports.profile in the profile folder. For example. DV AVI export has an entry: 2:HQ:DV:Avi DV:PAL::avformat:PAL:avi:format=avi vcodec=dvvideo acodec=pcm_s16le size=720x576 The last section of the line (after the last ":") is directly passed to FFMPEG (libavformat) I have to say that I am far from understanding all FFMPEG parameters, so I did just put some parameters that seemed to work for me, but if anyone with a better knowledge wants to spend some time on it, there is probably room for improvement. I think we could maybe one day ask on the ffmpeg-users mailing list what people think are the best parameters to convert a dv video (MLT internally works with dv resolution) to the various export formats... But for sure there is no easy answer. (you can see the exports.profile file online at: http://svn.sourceforge.net/viewvc/kdenlive/trunk/kdenlive/profiles/exports.profile?view=markup ) regards jb |

I have no text clips there. I have clip created from picture (png) and this clip is exported (it is first clip) but without transition (crossfade) at the end. I want to join picture video at start and end of my clip with crossfade between pictures and my clip. I have in second track 10s picture video (start), my clip, 10s picture video (stop). In first track I have 4 black 5s videos with transition (crossfade). For me it looks as problem with export transitions.

By default, MLT passes a value of zero for parameter qscale. Changing that value to 1 fixed my problem. Before submitting a patch to MLT, I would like to know if it also works for you, so could you please try to do the following : In Kdenlive export dialog, select an export format that doesn't work for you and copy the parameters that appear in the line just below the formats list. For example, parameter line for MPEG 320x200 medium is: format=mpeg video_rc_min_rate=0 video_bit_rate=500000 audio_bit_rate=64000 frequency=32000 size=320x200 progressive=1 Then go to the "Custom" tab in export dialog and create a new profile. Give the name you want, put the correct extension (mpeg for example) and paste the parameters from the buggy profile. Then, add "qscale=1" (without quotes) at the end of the parameters. Click ok and try exporting with that profile. Let me know if it solves your export problem. regards jb |

Yes. It works for me.
